Theories on Treaties_Comparative Cases

Bayan vs Zamora October 10, 2000

“Recognized as a treaty” means that the other contracting party accepts or acknowledges the agreement as a treaty. To require the other contracting state, the United States of America in this case, to submit the VFA to the United States Senate for concurrence pursuant to its Constitution, is to accord strict meaning to the phrase.
Moreover, it is inconsequential whether the United States treats the VFA only as an executive agreement because, under international law, an executive agreement is as binding as a treaty. To be sure, as long as the VFA possesses the elements of an agreement under international law, the said agreement is to be taken equally as a treaty.
A treaty, as defined by the Vienna Convention on the Law of Treaties, is “an international instrument concluded between States in written form and governed by international law, whether embodied in a single instrument or in two or more related instruments, and whatever its particular designation.” There are many other terms used for a treaty or international agreement, some of which are: act, protocol, agreement, compromis d’ arbitrage, concordat, convention, declaration, exchange of notes, pact, statute, charter and modus vivendi. All writers, from Hugo Grotius onward, have pointed out that the names or titles of international agreements included under the general term treaty have little or no legal significance. Certain terms are useful, but they furnish little more than mere description.
Article 2(2) of the Vienna Convention provides that “the provisions of paragraph 1 regarding the use of terms in the present Convention are without prejudice to the use of those terms, or to the meanings which may be given to them in the internal law of the State.”
Thus, in international law, there is no difference between treaties and executive agreements in their binding effect upon states concerned, as long as the negotiating functionaries have remained within their powers. International law continues to make no distinction between treaties and executive agreements: they are equally binding obligations upon nations.
In our jurisdiction, we have recognized the binding effect of executive agreements even without the concurrence of the Senate or Congress. In Commissioner of Customs vs. Eastern Sea Trading, we had occasion to pronounce:
“x x x the right of the Executive to enter into binding agreements without the necessity of subsequent congressional approval has been confirmed by long usage. From the earliest days of our history we have entered into executive agreements covering such subjects as commercial and consular relations, most-favored-nation rights, patent rights, trademark and copyright protection, postal and navigation arrangements and the settlement of claims. The validity of these has never been seriously questioned by our courts.
The records reveal that the United States Government, through Ambassador Thomas C. Hubbard, has stated that the United States government has fully committed to living up to the terms of the VFA. For as long as the united States of America accepts or acknowledges the VFA as a treaty, and binds itself further to comply with its obligations under the treaty, there is indeed marked compliance with the mandate of the Constitution.
Worth stressing too, is that the ratification, by the President, of the VFA and the concurrence of the Senate should be taken as a clear an unequivocal expression of our nation’s consent to be bound by said treaty, with the concomitant duty to uphold the obligations and responsibilities embodied thereunder.
Ratification is generally held to be an executive act, undertaken by the head of the state or of the government, as the case may be, through which the formal acceptance of the treaty is proclaimed. A State may provide in its domestic legislation the process of ratification of a treaty. The consent of the State to be bound by a treaty is expressed by ratification when: (a) the treaty provides for such ratification, (b) it is otherwise established that the negotiating States agreed that ratification should be required, (c) the representative of the State has signed the treaty subject to ratification, or (d) the intention of the State to sign the treaty subject to ratification appears from the full powers of its representative, or was expressed during the negotiation.
In our jurisdiction, the power to ratify is vested in the President and not, as commonly believed, in the legislature. The role of the Senate is limited only to giving or withholding its consent, or concurrence, to the ratification.
With the ratification of the VFA, which is equivalent to final acceptance, and with the exchange of notes between the Philippines and the United States of America, it now becomes obligatory and incumbent on our part, under the principles of international law, to be bound by the terms of the agreement. Thus, no less than Section 2, Article II of the Constitution, declares that the Philippines adopts the generally accepted principles of international law as part of the law of the land and adheres to the policy of peace, equality, justice, freedom, cooperation and amity with all nations.
As a member of the family of nations, the Philippines agrees to be bound by generally accepted rules for the conduct of its international relations. While the international obligation devolves upon the state and not upon any particular branch, institution, or individual member of its government, the Philippines is nonetheless responsible for violations committed by any branch or subdivision of its government or any official thereof. As an integral part of the community of nations, we are responsible to assure that our government, Constitution and laws will carry out our international obligation. Hence, we cannot readily plead the Constitution as a convenient excuse for non-compliance with our obligations, duties and responsibilities under international law.
Beyond this, Article 13 of the Declaration of Rights and Duties of States adopted by the International Law Commission in 1949 provides: “Every State has the duty to carry out in good faith its obligations arising from treaties and other sources of international law, and it may not invoke provisions in its constitution or its laws as an excuse for failure to perform this duty.”
Equally important is Article 26 of the convention which provides that “Every treaty in force is binding upon the parties to it and must be performed by them in good faith.” This is known as the principle of pacta sunt servanda which preserves the sanctity of treaties and have been one of the most fundamental principles of positive international law, supported by the jurisprudence of international tribunals.

ABAYA vs EBDANI February 14, 2007
The petitioners, in order to place the procurement process undertaken for the CP I project within the ambit of RA 9184, vigorously assert that Loan Agreement No. PH-P204 is neither a treaty, an international agreement nor an executive agreement. They cite Executive Order No. 459 dated November 25, 1997 where the three agreements are defined in this wise:
a) International agreement � shall refer to a contract or understanding, regardless of nomenclature, entered into between the Philippines and another government in written form and governed by international law, whether embodied in a single instrument or in two or more related instruments.
b) Treaties � international agreements entered into by the Philippines which require legislative concurrence after executive ratification. This term may include compacts like conventions, declarations, covenants and acts.
c) Executive agreements � similar to treaties except that they do not require legislative concurrence.
The petitioners mainly argue that Loan Agreement No. PH-P204 does not fall under any of the three categories because to be any of the three, an agreement had to be one where the parties are the Philippines as a State and another State. The JBIC, the petitioners maintain, is a Japanese banking agency, which presumably has a separate juridical personality from the Japanese Government.
The petitioners� arguments fail to persuade. The Court holds that Loan Agreement No. PH-P204 taken in conjunction with the Exchange of Notes dated December 27, 1999 between the Japanese Government and the Philippine Government is an executive agreement.
To recall, Loan Agreement No. PH-P204 was executed by and between the JBIC and the Philippine Government pursuant to the Exchange of Notes executed by and between Mr. Yoshihisa Ara, Ambassador Extraordinary and Plenipotentiary of Japan to the Philippines, and then Foreign Affairs Secretary Siazon, in behalf of their respective governments. The Exchange of Notes expressed that the two governments have reached an understanding concerning Japanese loans to be extended to the Philippines and that these loans were aimed at promoting our country�s economic stabilization and development efforts.
Loan Agreement No. PH-P204 was subsequently executed and it declared that it was so entered by the parties "[i]n the light of the contents of the Exchange of Notes between the Government of Japan and the Government of the Republic of the Philippines dated December 27, 1999, concerning Japanese loans to be extended with a view to promoting the economic stabilization and development efforts of the Republic of the Philippines." Under the circumstances, the JBIC may well be considered an adjunct of the Japanese Government. Further, Loan Agreement No. PH-P204 is indubitably an integral part of the Exchange of Notes. It forms part of the Exchange of Notes such that it cannot be properly taken independent thereof.
In this connection, it is well to understand the definition of an "exchange of notes" under international law. The term is defined in the United Nations Treaty Collection in this wise:
An "exchange of notes" is a record of a routine agreement that has many similarities with the private law contract. The agreement consists of the exchange of two documents, each of the parties being in the possession of the one signed by the representative of the other. Under the usual procedure, the accepting State repeats the text of the offering State to record its assent. The signatories of the letters may be government Ministers, diplomats or departmental heads. The technique of exchange of notes is frequently resorted to, either because of its speedy procedure, or, sometimes, to avoid the process of legislative approval.
It is stated that "treaties, agreements, conventions, charters, protocols, declarations, memoranda of understanding, modus vivendi and exchange of notes" all refer to "international instruments binding at international law." It is further explained that-
Although these instruments differ from each other by title, they all have common features and international law has applied basically the same rules to all these instruments. These rules are the result of long practice among the States, which have accepted them as binding norms in their mutual relations. Therefore, they are regarded as international customary law. Since there was a general desire to codify these customary rules, two international conventions were negotiated. The 1969 Vienna Convention on the Law of Treaties ("1969 Vienna Convention"), which entered into force on 27 January 1980, contains rules for treaties concluded between States. The 1986 Vienna Convention on the Law of Treaties between States and International Organizations ("1986 Vienna Convention"), which has still not entered into force, added rules for treaties with international organizations as parties. Both the 1969 Vienna Convention and the 1986 Vienna Convention do not distinguish between the different designations of these instruments. Instead, their rules apply to all of those instruments as long as they meet the common requirements.
Significantly, an exchange of notes is considered a form of an executive agreement, which becomes binding through executive action without the need of a vote by the Senate or Congress. The following disquisition by Francis B. Sayre, former United States High Commissioner to the Philippines, entitled "The Constitutionality of Trade Agreement Acts," quoted in Commissioner of Customs v. Eastern Sea Trading, is apropos:
Agreements concluded by the President which fall short of treaties are commonly referred to as executive agreements and are no less common in our scheme of government than are the more formal instruments � treaties and conventions. They sometimes take the form of exchange of notes and at other times that of more formal documents denominated "agreements" or "protocols". The point where ordinary correspondence between this and other governments ends and agreements � whether denominated executive agreements or exchange of notes or otherwise � begin, may sometimes be difficult of ready ascertainment. It would be useless to undertake to discuss here the large variety of executive agreements as such, concluded from time to time. Hundreds of executive agreements, other than those entered into under the trade-agreements act, have been negotiated with foreign governments. x x x
The Exchange of Notes dated December 27, 1999, stated, inter alia, that the Government of Japan would extend loans to the Philippines with a view to promoting its economic stabilization and development efforts; Loan I in the amount of Y79,8651,000,000 would be extended by the JBIC to the Philippine Government to implement the projects in the List A (including the Arterial Road Links Development Project - Phase IV); and that such loan (Loan I) would be used to cover payments to be made by the Philippine executing agencies to suppliers, contractors and/or consultants of eligible source countries under such contracts as may be entered into between them for purchases of products and/or services required for the implementation of the projects enumerated in the List A. With respect to the procurement of the goods and services for the projects, it bears reiterating that as stipulated:
3. The Government of the Republic of the Philippines will ensure that the products and/or services mentioned in sub-paragraph (1) of paragraph 3 of Part I and sub-paragraph (1) of paragraph 4 of Part II are procured in accordance with the guidelines for procurement of the Bank, which set forth, inter alia, the procedures of international tendering to be followed except where such procedures are inapplicable or inappropriate.
The JBIC Procurements Guidelines, as quoted earlier, forbids any procedure under which bids above or below a predetermined bid value assessment are automatically disqualified. Succinctly put, it absolutely prohibits the imposition of ceilings on bids.
Under the fundamental principle of international law of pacta sunt servanda, which is, in fact, embodied in Section 4 of RA 9184 as it provides that "[a]ny treaty or international or executive agreement affecting the subject matter of this Act to which the Philippine government is a signatory shall be observed," the DPWH, as the executing agency of the projects financed by Loan Agreement No. PH-P204, rightfully awarded the contract for the implementation of civil works for the CP I project to private respondent China Road & Bridge Corporation.

DEPT OF BUDGET vs KOLONWELL TRADING June 8, 2007
The question as to whether or not foreign loan agreements with international financial institutions, such as Loan No. 7118-PH, partake of an executive or international agreement within the purview of the Section 4 of R.A. No. 9184, has been answered by the Court in the affirmative in Abaya, supra. Significantly,Abaya declared that the RP-JBIC loan agreement was to be of governing application over the CP I project and that the JBIC Procurement Guidelines, as stipulated in the loan agreement, shall primarily govern the procurement of goods necessary to implement the main project.

Under the fundamental international law principle of pacta sunt servanda which is in fact embodied in the afore-quoted Section 4 of R.A. No. 9184, the RP, as borrower, bound itself to perform in good faith its duties and obligation under Loan No. 7118- PH. Applying this postulate in the concrete to this case,the IABAC was legally obliged to comply with, or accord primacy to, the WB Guidelines on the conduct and implementation of the bidding/procurement process in question.


LIM vs EXECUTIVE SECRETARY April 11, 2002

The first question that should be addressed is whether "Balikatan 02-1" is covered by the Visiting Forces Agreement. To resolve this, it is necessary to refer to the V FA itself: Not much help can be had therefrom, unfortunately, since the terminology employed is itself the source of the problem. The VFA permits United States personnel to engage, on an impermanent basis, in "activities," the exact meaning of which was left undefined. The expression is ambiguous, permitting a wide scope of undertakings subject only to the approval of the Philippine government.8 The sole encumbrance placed on its definition is couched in the negative, in that United States personnel must "abstain from any activity inconsistent with the spirit of this agreement, and in particular, from any political activity."9 All other activities, in other words, are fair game.
We are not left completely unaided, however. The Vienna Convention on the Law of Treaties, which contains provisos governing interpretations of international agreements, state:
SECTION 3. INTERPRETATION OF TREATIES
Article 31
General rule of interpretation
1. A treaty shall be interpreted in good faith ill accordance with the ordinary meaning to be given to the tenus of the treaty in their context and in the light of its object and purpose.
2. The context for the purpose of the interpretation of a treaty shall comprise, in addition to the text, including its preamble and annexes:
(a) any agreement relating to the treaty which was made between all the parties in connexion with the conclusion of the treaty;
(b) any instrument which was made by one or more parties in connexion with the conclusion of the treaty and accepted by the other parties as an instrument related to the party .
3. There shall be taken into account, together with the context:
(a) any subsequent agreement between the parties regarding the interpretation of the treaty or the application of its provisions;
(b) any subsequent practice in the application of the treaty which establishes the agreement of the parties regarding its interpretation;
(c) any relevant rules of international law applicable in the relations between the parties.
4. A special meaning shall be given to a term if it is established that the parties so intended.
Article 32
Supplementary means of interpretation
Recourse may be had to supplementary means of interpretation, including the preparatory work of the treaty and the circumstances of its conclusion, in order to confirm the meaning resulting from the application of article 31, or to determine the meaning when the interpretation according to article 31 :
(a) leaves the meaning ambiguous or obscure; or
(b) leads to a result which is manifestly absurd unreasonable.
It is clear from the foregoing that the cardinal rule of interpretation must involve an examination of the text, which is presumed to verbalize the parties' intentions. The Convention likewise dictates what may be used as aids to deduce the meaning of terms, which it refers to as the context of the treaty, as well as other elements may be taken into account alongside the aforesaid context. As explained by a writer on the Convention ,
[t]he Commission's proposals (which were adopted virtually without change by the conference and are now reflected in Articles 31 and 32 of the Convention) were clearly based on the view that the text of a treaty must be presumed to be the authentic expression of the intentions of the parties; the Commission accordingly came down firmly in favour of the view that 'the starting point of interpretation is the elucidation of the meaning of the text, not an investigation ab initio into the intentions of the parties'. This is not to say that the travauxpreparatoires of a treaty , or the circumstances of its conclusion, are relegated to a subordinate, and wholly ineffective, role. As Professor Briggs points out, no rigid temporal prohibition on resort to travaux preparatoires of a treaty was intended by the use of the phrase 'supplementary means of interpretation' in what is now Article 32 of the Vienna Convention. The distinction between the general rule of interpretation and the supplementary means of interpretation is intended rather to ensure that the supplementary means do not constitute an alternative, autonomous method of interpretation divorced from the general rule.1O
The Terms of Reference rightly fall within the context of the VFA.
After studied reflection, it appeared farfetched that the ambiguity surrounding the meaning of the word .'activities" arose from accident. In our view, it was deliberately made that way to give both parties a certain leeway in negotiation. In this manner, visiting US forces may sojourn in Philippine territory for purposes other than military. As conceived, the joint exercises may include training on new techniques of patrol and surveillance to protect the nation's marine resources, sea search-and-rescue operations to assist vessels in distress, disaster relief operations, civic action projects such as the building of school houses, medical and humanitarian missions, and the like.
Under these auspices, the VFA gives legitimacy to the current Balikatan exercises. It is only logical to assume that .'Balikatan 02-1," a "mutual anti- terrorism advising, assisting and training exercise," falls under the umbrella of sanctioned or allowable activities in the context of the agreement. Both the history and intent of the Mutual Defense Treaty and the V FA support the conclusion that combat-related activities -as opposed to combat itself -such as the one subject of the instant petition, are indeed authorized.
That is not the end of the matter, though. Granted that "Balikatan 02-1" is permitted under the terms of the VFA, what may US forces legitimately do in furtherance of their aim to provide advice, assistance and training in the global effort against terrorism? Differently phrased, may American troops actually engage in combat in Philippine territory? The Terms of Reference are explicit enough. Paragraph 8 of section I stipulates that US exercise participants may not engage in combat "except in self-defense." We wryly note that this sentiment is admirable in the abstract but difficult in implementation. The target of "Balikatan 02-1 I" the Abu Sayyaf, cannot reasonably be expected to sit idly while the battle is brought to their very doorstep. They cannot be expected to pick and choose their targets for they will not have the luxury of doing so. We state this point if only to signify our awareness that the parties straddle a fine line, observing the honored legal maxim "Nemo potest facere per alium quod non potest facere per directum."11 The indirect violation is actually petitioners' worry, that in reality, "Balikatan 02-1 " is actually a war principally conducted by the United States government, and that the provision on self-defense serves only as camouflage to conceal the true nature of the exercise. A clear pronouncement on this matter thereby becomes crucial.
In our considered opinion, neither the MDT nor the V FA allow foreign troops to engage in an offensive war on Philippine territory. We bear in mind the salutary proscription stated in the Charter of the United Nations, to wit:
Article 2
The Organization and its Members, in pursuit of the Purposes stated in Article 1, shall act in accordance with the following Principles.
xxx xxx xxx xxx
4. All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations.
xxx xxx xxx xxx
In the same manner, both the Mutual Defense Treaty and the Visiting Forces Agreement, as in all other treaties and international agreements to which the Philippines is a party, must be read in the context of the 1987 Constitution. In particular, the Mutual Defense Treaty was concluded way before the present Charter, though it nevertheless remains in effect as a valid source of international obligation. The present Constitution contains key provisions useful in determining the extent to which foreign military troops are allowed in Philippine territory. Thus, in the Declaration of Principles and State Policies, it is provided that:
xxx xxx xxx xxx
SEC. 2. The Philippines renounces war as an instrument of national policy, adopts the generally accepted principles of international law as part of the law of the land and adheres to the policy of peace, equality, justice, freedom, cooperation, and amity with all nations.
xxx xxx xxx xxx
SEC. 7. The State shall pursue an independent foreign policy. In its relations with other states the paramount consideration shall be national sovereignty, territorial integrity, national interest, and the right to self- determination.
SEC. 8. The Philippines, consistent with the national interest, adopts and pursues a policy of freedom from nuclear weapons in the country.
xxx xxx xxx xxx
The Constitution also regulates the foreign relations powers of the Chief Executive when it provides that "[n]o treaty or international agreement shall be valid and effective unless concurred in by at least two-thirds of all the members of the Senate."12 Even more pointedly, the Transitory Provisions state:
Sec. 25. After the expiration in 1991 of the Agreement between the Republic of the Philippines and the United States of America concerning Military Bases, foreign military bases, troops or facilities shall not be allowed in the Philippines except under a treaty duly concurred in by the Senate and, when the Congress so requires, ratified by a majority of the votes cast by the people in a national referendum held for that purpose, and recognized as a treaty by the other contracting state.
The aforequoted provisions betray a marked antipathy towards foreign military presence in the country, or of foreign influence in general. Hence, foreign troops are allowed entry into the Philippines only by way of direct exception. Conflict arises then between the fundamental law and our obligations arising from international agreements.
A rather recent formulation of the relation of international law vis-a-vis municipal law was expressed in Philip Morris, Inc. v. Court of Appeals,13 to wit:
xxx Withal, the fact that international law has been made part of the law of the land does not by any means imply the primacy of international law over national law in the municipal sphere. Under the doctrine of incorporation as applied in most countries, rules of international law are given a standing equal, not superior, to national legislation.
This is not exactly helpful in solving the problem at hand since in trying to find a middle ground, it favors neither one law nor the other, which only leaves the hapless seeker with an unsolved dilemma. Other more traditional approaches may offer valuable insights.
From the perspective of public international law, a treaty is favored over municipal law pursuant to the principle of pacta sunt servanda. Hence, "[e]very treaty in force is binding upon the parties to it and must be performed by them in good faith."14 Further, a party to a treaty is not allowed to "invoke the provisions of its internal law as justification for its failure to perform a treaty."15
Our Constitution espouses the opposing view. Witness our jurisdiction as I stated in section 5 of Article VIII:
The Supreme Court shall have the following powers:
xxx xxx xxx xxx
(2) Review, revise, reverse, modify, or affirm on appeal or certiorari, as the law or the Rules of Court may provide, final judgments and order of lower courts in:
(A) All cases in which the constitutionality or validity of any treaty, international or executive agreement, law, presidential decree, proclamation, order, instruction, ordinance, or regulation is in question.
xxx xxx xxx xxx
In Ichong v. Hernandez,16 we ruled that the provisions of a treaty are always subject to qualification or amendment by a subsequent law, or that it is subject to the police power of the State. In Gonzales v. Hechanova,17
xxx As regards the question whether an international agreement may be invalidated by our courts, suffice it to say that the Constitution of the Philippines has clearly settled it in the affirmative, by providing, in Section 2 of Article VIII thereof, that the Supreme Court may not be deprived "of its jurisdiction to review, revise, reverse, modify, or affirm on appeal, certiorari, or writ of error as the law or the rules of court may provide, final judgments and decrees of inferior courts in -( I) All cases in which the constitutionality or validity of any treaty, law, ordinance, or executive order or regulation is in question." In other words, our Constitution authorizes the nullification of a treaty, not only when it conflicts with the fundamental law, but, also, when it runs counter to an act of Congress.
The foregoing premises leave us no doubt that US forces are prohibited / from engaging in an offensive war on Philippine territory.

COMMISSIONER OF INTERNAL REVENUE vs S.C. JOHNSON & SON
June 25, 1999

With respect to the merits of this petition, the main point of contention in this appeal is the interpretation of Article 13 (2) (b) (iii) of the RP-US Tax Treaty regarding the rate of tax to be imposed by the Philippines upon royalties received by a non-resident foreign corporation. The provision states insofar as pertinent that �
1) Royalties derived by a resident of one of the Contracting States from sources within the other Contracting State may be taxed by both Contracting States.
2) However, the tax imposed by that Contracting State shall not exceed.
a) In the case of the United States, 15 percent of the gross amount of the royalties, and
b) In the case of the Philippines, the least of:
(i) 25 percent of the gross amount of the royalties;
(ii) 15 percent of the gross amount of the royalties, where the royalties are paid by a corporation registered with the Philippine Board of Investments and engaged in preferred areas of activities; and
(iii) the lowest rate of Philippine tax that may be imposed on royalties of the same kind paid under similar circumstances to a resident of a third State.
x x x x x x x x x
(emphasis supplied)
Respondent S. C. Johnson and Son, Inc. claims that on the basis of the quoted provision, it is entitled to the concessional tax rate of 10 percent on royalties based on Article 12 (2) (b) of the RP-Germany Tax Treaty which provides:
(2) However, such royalties may also be taxed in the Contracting State in which they arise, and according to the law of that State, but the tax so charged shall not exceed:
x x x x x x x x x
b) 10 percent of the gross amount of royalties arising from the use of, or the right to use, any patent, trademark, design or model, plan, secret formula or process, or from the use of or the right to use, industrial, commercial, or scientific equipment, or for information concerning industrial, commercial or scientific experience.
For as long as the transfer of technology, under Philippine law, is subject to approval, the limitation of the tax rate mentioned under b) shall, in the case of royalties arising in the Republic of the Philippines, only apply if the contract giving rise to such royalties has been approved by the Philippine competent authorities.
The RP-US Tax Treaty is just one of a number of bilateral treaties which the Philippines has entered into for the avoidance of double taxation.9 The purpose of these international agreements is to reconcile the national fiscal legislations of the contracting parties in order to help the taxpayer avoid simultaneous taxation in two different jurisdictions.10 More precisely, the tax conventions are drafted with a view towards the elimination of international juridical double taxation, which is defined as the imposition of comparable taxes in two or more states on the same taxpayer in respect of the same subject matter and for identical periods.11 The apparent rationale for doing away with double taxation is of encourage the free flow of goods and services and the movement of capital, technology and persons between countries, conditions deemed vital in creating robust and dynamic economies.12 Foreign investments will only thrive in a fairly predictable and reasonable international investment climate and the protection against double taxation is crucial in creating such a climate.13
Double taxation usually takes place when a person is resident of a contracting state and derives income from, or owns capital in, the other contracting state and both states impose tax on that income or capital. In order to eliminate double taxation, a tax treaty resorts to several methods. First, it sets out the respective rights to tax of the state of source or situs and of the state of residence with regard to certain classes of income or capital. In some cases, an exclusive right to tax is conferred on one of the contracting states; however, for other items of income or capital, both states are given the right to tax, although the amount of tax that may be imposed by the state of source is limited.14
The second method for the elimination of double taxation applies whenever the state of source is given a full or limited right to tax together with the state of residence. In this case, the treaties make it incumbent upon the state of residence to allow relief in order to avoid double taxation. There are two methods of relief � the exemption method and the credit method. In the exemption method, the income or capital which is taxable in the state of source or situs is exempted in the state of residence, although in some instances it may be taken into account in determining the rate of tax applicable to the taxpayer's remaining income or capital. On the other hand, in the credit method, although the income or capital which is taxed in the state of source is still taxable in the state of residence, the tax paid in the former is credited against the tax levied in the latter. The basic difference between the two methods is that in the exemption method, the focus is on the income or capital itself, whereas the credit method focuses upon the tax.15
In negotiating tax treaties, the underlying rationale for reducing the tax rate is that the Philippines will give up a part of the tax in the expectation that the tax given up for this particular investment is not taxed by the other country.16 Thus the petitioner correctly opined that the phrase "royalties paid under similar circumstances" in the most favored nation clause of the US-RP Tax Treaty necessarily contemplated "circumstances that are tax-related".
In the case at bar, the state of source is the Philippines because the royalties are paid for the right to use property or rights, i.e. trademarks, patents and technology, located within the Philippines.17 The United States is the state of residence since the taxpayer, S. C. Johnson and Son, U. S. A., is based there. Under the RP-US Tax Treaty, the state of residence and the state of source are both permitted to tax the royalties, with a restraint on the tax that may be collected by the state of source.18 Furthermore, the method employed to give relief from double taxation is the allowance of a tax credit to citizens or residents of the United States (in an appropriate amount based upon the taxes paid or accrued to the Philippines) against the United States tax, but such amount shall not exceed the limitations provided by United States law for the taxable year.19 Under Article 13 thereof, the Philippines may impose one of three rates � 25 percent of the gross amount of the royalties; 15 percent when the royalties are paid by a corporation registered with the Philippine Board of Investments and engaged in preferred areas of activities; or the lowest rate of Philippine tax that may be imposed on royalties of the same kind paid under similar circumstances to a resident of a third state.
Given the purpose underlying tax treaties and the rationale for the most favored nation clause, the concessional tax rate of 10 percent provided for in the RP-Germany Tax Treaty should apply only if the taxes imposed upon royalties in the RP-US Tax Treaty and in the RP-Germany Tax Treaty are paid under similar circumstances. This would mean that private respondent must prove that the RP-US Tax Treaty grants similar tax reliefs to residents of the United States in respect of the taxes imposable upon royalties earned from sources within the Philippines as those allowed to their German counterparts under the RP-Germany Tax Treaty.
The RP-US and the RP-West Germany Tax Treaties do not contain similar provisions on tax crediting. Article 24 of the RP-Germany Tax Treaty, supra, expressly allows crediting against German income and corporation tax of 20% of the gross amount of royalties paid under the law of the Philippines. On the other hand, Article 23 of the RP-US Tax Treaty, which is the counterpart provision with respect to relief for double taxation, does not provide for similar crediting of 20% of the gross amount of royalties paid. Said Article 23 reads:
Article 23
Relief from double taxation
Double taxation of income shall be avoided in the following manner:
1) In accordance with the provisions and subject to the limitations of the law of the United States (as it may be amended from time to time without changing the general principle thereof), the United States shall allow to a citizen or resident of the United States as a credit against the United States tax the appropriate amount of taxes paid or accrued to the Philippines and, in the case of a United States corporation owning at least 10 percent of the voting stock of a Philippine corporation from which it receives dividends in any taxable year, shall allow credit for the appropriate amount of taxes paid or accrued to the Philippines by the Philippine corporation paying such dividends with respect to the profits out of which such dividends are paid. Such appropriate amount shall be based upon the amount of tax paid or accrued to the Philippines, but the credit shall not exceed the limitations (for the purpose of limiting the credit to the United States tax on income from sources within the Philippines or on income from sources outside the United States) provided by United States law for the taxable year. . . .
The reason for construing the phrase "paid under similar circumstances" as used in Article 13 (2) (b) (iii) of the RP-US Tax Treaty as referring to taxes is anchored upon a logical reading of the text in the light of the fundamental purpose of such treaty which is to grant an incentive to the foreign investor by lowering the tax and at the same time crediting against the domestic tax abroad a figure higher than what was collected in the Philippines.
In one case, the Supreme Court pointed out that laws are not just mere compositions, but have ends to be achieved and that the general purpose is a more important aid to the meaning of a law than any rule which grammar may lay down.20 It is the duty of the courts to look to the object to be accomplished, the evils to be remedied, or the purpose to be subserved, and should give the law a reasonable or liberal construction which will best effectuate its purpose.21 The Vienna Convention on the Law of Treaties states that a treaty shall be interpreted in good faith in accordance with the ordinary meaning to be given to the terms of the treaty in their context and in the light of its object and purpose.22
As stated earlier, the ultimate reason for avoiding double taxation is to encourage foreign investors to invest in the Philippines � a crucial economic goal for developing countries.23 The goal of double taxation conventions would be thwarted if such treaties did not provide for effective measures to minimize, if not completely eliminate, the tax burden laid upon the income or capital of the investor. Thus, if the rates of tax are lowered by the state of source, in this case, by the Philippines, there should be a concomitant commitment on the part of the state of residence to grant some form of tax relief, whether this be in the form of a tax credit or exemption.24 Otherwise, the tax which could have been collected by the Philippine government will simply be collected by another state, defeating the object of the tax treaty since the tax burden imposed upon the investor would remain unrelieved. If the state of residence does not grant some form of tax relief to the investor, no benefit would redound to the Philippines, i.e., increased investment resulting from a favorable tax regime, should it impose a lower tax rate on the royalty earnings of the investor, and it would be better to impose the regular rate rather than lose much-needed revenues to another country.
At the same time, the intention behind the adoption of the provision on "relief from double taxation" in the two tax treaties in question should be considered in light of the purpose behind the most favored nation clause.
The purpose of a most favored nation clause is to grant to the contracting party treatment not less favorable than that which has been or may be granted to the "most favored" among other countries.25 The most favored nation clause is intended to establish the principle of equality of international treatment by providing that the citizens or subjects of the contracting nations may enjoy the privileges accorded by either party to those of the most favored nation.26 The essence of the principle is to allow the taxpayer in one state to avail of more liberal provisions granted in another tax treaty to which the country of residence of such taxpayer is also a party provided that the subject matter of taxation, in this case royalty income, is the same as that in the tax treaty under which the taxpayer is liable. Both Article 13 of the RP-US Tax Treaty and Article 12 (2) (b) of the RP-West Germany Tax Treaty, above-quoted, speaks of tax on royalties for the use of trademark, patent, and technology. The entitlement of the 10% rate by U.S. firms despite the absence of a matching credit (20% for royalties) would derogate from the design behind the most grant equality of international treatment since the tax burden laid upon the income of the investor is not the same in the two countries. The similarity in the circumstances of payment of taxes is a condition for the enjoyment of most favored nation treatment precisely to underscore the need for equality of treatment.
We accordingly agree with petitioner that since the RP-US Tax Treaty does not give a matching tax credit of 20 percent for the taxes paid to the Philippines on royalties as allowed under the RP-West Germany Tax Treaty, private respondent cannot be deemed entitled to the 10 percent rate granted under the latter treaty for the reason that there is no payment of taxes on royalties under similar circumstances.
It bears stress that tax refunds are in the nature of tax exemptions. As such they are regarded as in derogation of sovereign authority and to be construed strictissimi juris against the person or entity claiming the exemption.27 The burden of proof is upon him who claims the exemption in his favor and he must be able to justify his claim by the clearest grant of organic or statute law.28 Private respondent is claiming for a refund of the alleged overpayment of tax on royalties; however, there is nothing on record to support a claim that the tax on royalties under the RP-US Tax Treaty is paid under similar circumstances as the tax on royalties under the RP-West Germany Tax Treaty.

PIMENTEL VS EXECUTIVE SECRETARY July 6, 2005
The core issue in this petition for mandamus is whether the Executive Secretary and the Department of Foreign Affairs have a ministerial duty to transmit to the Senate the copy of the Rome Statute signed by a member of the Philippine Mission to the United Nations even without the signature of the President.
We rule in the negative

In our system of government, the President, being the head of state, is regarded as the sole organ and authority in external relations and is the country’s sole representative with foreign nations.[12] As the chief architect of foreign policy, the President acts as the country’s mouthpiece with respect to international affairs. Hence, the President is vested with the authority to deal with foreign states and governments, extend or withhold recognition, maintain diplomatic relations, enter into treaties, and otherwise transact the business of foreign relations.[13] In the realm of treaty-making, the President has the sole authority to negotiate with other states.
Nonetheless, while the President has the sole authority to negotiate and enter into treaties, the Constitution provides a limitation to his power by requiring the concurrence of 2/3 of all the members of the Senate for the validity of the treaty entered into by him. Section 21, Article VII of the 1987 Constitution provides that “no treaty or international agreement shall be valid and effective unless concurred in by at least two-thirds of all the Members of the Senate.” The 1935 and the 1973 Constitution also required the concurrence by the legislature to the treaties entered into by the executive. Section 10 (7), Article VII of the 1935 Constitution provided:
Sec. 10. (7) The President shall have the power, with the concurrence of two-thirds of all the Members of the Senate, to make treaties xxx.

Section 14 (1) Article VIII of the 1973 Constitution stated:
Sec. 14. (1) Except as otherwise provided in this Constitution, no treaty shall be valid and effective unless concurred in by a majority of all the Members of the Batasang Pambansa.

The participation of the legislative branch in the treaty-making process was deemed essential to provide a check on the executive in the field of foreign relations.[14] By requiring the concurrence of the legislature in the treaties entered into by the President, the Constitution ensures a healthy system of checks and balance necessary in the nation’s pursuit of political maturity and growth.[15]
In filing this petition, the petitioners interpret Section 21, Article VII of the 1987 Constitution to mean that the power to ratify treaties belongs to the Senate.
We disagree.
Justice Isagani Cruz, in his book on International Law, describes the treaty-making process in this wise:
The usual steps in the treaty-making process are: negotiation, signature, ratification, and exchange of the instruments of ratification. The treaty may then be submitted for registration and publication under the U.N. Charter, although this step is not essential to the validity of the agreement as between the parties.

Negotiation may be undertaken directly by the head of state but he now usually assigns this task to his authorized representatives. These representatives are provided with credentials known as full powers, which they exhibit to the other negotiators at the start of the formal discussions. It is standard practice for one of the parties to submit a draft of the proposed treaty which, together with the counter-proposals, becomes the basis of the subsequent negotiations. The negotiations may be brief or protracted, depending on the issues involved, and may even “collapse” in case the parties are unable to come to an agreement on the points under consideration.

If and when the negotiators finally decide on the terms of the treaty, the same is opened for signature. This step is primarily intended as a means of authenticating the instrument and for the purpose of symbolizing the good faith of the parties; but, significantly, it does not indicate the final consent of the state in cases where ratification of the treaty is required. The document is ordinarily signed in accordance with the alternat, that is, each of the several negotiators is allowed to sign first on the copy which he will bring home to his own state.

Ratification, which is the next step, is the formal act by which a state confirms and accepts the provisions of a treaty concluded by its representatives. The purpose of ratification is to enable the contracting states to examine the treaty more closely and to give them an opportunity to refuse to be bound by it should they find it inimical to their interests. It is for this reason that most treaties are made subject to the scrutiny and consent of a department of the government other than that which negotiated them.

x x x

The last step in the treaty-making process is the exchange of the instruments of ratification, which usually also signifies the effectivity of the treaty unless a different date has been agreed upon by the parties. Where ratification is dispensed with and no effectivity clause is embodied in the treaty, the instrument is deemed effective upon its signature.[16] [emphasis supplied]

Petitioners’ arguments equate the signing of the treaty by the Philippine representative with ratification. It should be underscored that the signing of the treaty and the ratification are two separate and distinct steps in the treaty-making process. As earlier discussed, the signature is primarily intended as a means of authenticating the instrument and as a symbol of the good faith of the parties. It is usually performed by the state’s authorized representative in the diplomatic mission. Ratification, on the other hand, is the formal act by which a state confirms and accepts the provisions of a treaty concluded by its representative. It is generally held to be an executive act, undertaken by the head of the state or of the government.[17] Thus, Executive Order No. 459 issued by President Fidel V. Ramos on November 25, 1997 provides the guidelines in the negotiation of international agreements and its ratification. It mandates that after the treaty has been signed by the Philippine representative, the same shall be transmitted to the Department of Foreign Affairs. The Department of Foreign Affairs shall then prepare the ratification papers and forward the signed copy of the treaty to the President for ratification. After the President has ratified the treaty, the Department of Foreign Affairs shall submit the same to the Senate for concurrence. Upon receipt of the concurrence of the Senate, the Department of Foreign Affairs shall comply with the provisions of the treaty to render it effective. Section 7 of Executive Order No. 459 reads:


Sec. 7. Domestic Requirements for the Entry into Force of a Treaty or an Executive Agreement. — The domestic requirements for the entry into force of a treaty or an executive agreement, or any amendment thereto, shall be as follows:

A. Executive Agreements.

i. All executive agreements shall be transmitted to the Department of Foreign Affairs after their signing for the preparation of the ratification papers. The transmittal shall include the highlights of the agreements and the benefits which will accrue to the Philippines arising from them.

ii. The Department of Foreign Affairs, pursuant to the endorsement by the concerned agency, shall transmit the agreements to the President of the Philippines for his ratification. The original signed instrument of ratification shall then be returned to the Department of Foreign Affairs for appropriate action.

B. Treaties.

i. All treaties, regardless of their designation, shall comply with the requirements provided in sub-paragraph[s] 1 and 2, item A (Executive Agreements) of this Section. In addition, the Department of Foreign Affairs shall submit the treaties to the Senate of the Philippines for concurrence in the ratification by the President. A certified true copy of the treaties, in such numbers as may be required by the Senate, together with a certified true copy of the ratification instrument, shall accompany the submission of the treaties to the Senate.

ii. Upon receipt of the concurrence by the Senate, the Department of Foreign Affairs shall comply with the provision of the treaties in effecting their entry into force.

Petitioners’ submission that the Philippines is bound under treaty law and international law to ratify the treaty which it has signed is without basis. The signature does not signify the final consent of the state to the treaty. It is the ratification that binds the state to the provisions thereof. In fact, the Rome Statute itself requires that the signature of the representatives of the states be subject to ratification, acceptance or approval of the signatory states. Ratification is the act by which the provisions of a treaty are formally confirmed and approved by a State. By ratifying a treaty signed in its behalf, a state expresses its willingness to be bound by the provisions of such treaty. After the treaty is signed by the state’s representative, the President, being accountable to the people, is burdened with the responsibility and the duty to carefully study the contents of the treaty and ensure that they are not inimical to the interest of the state and its people. Thus, the President has the discretion even after the signing of the treaty by the Philippine representative whether or not to ratify the same. The Vienna Convention on the Law of Treaties does not contemplate to defeat or even restrain this power of the head of states. If that were so, the requirement of ratification of treaties would be pointless and futile. It has been held that a state has no legal or even moral duty to ratify a treaty which has been signed by its plenipotentiaries.[18] There is no legal obligation to ratify a treaty, but it goes without saying that the refusal must be based on substantial grounds and not on superficial or whimsical reasons. Otherwise, the other state would be justified in taking offense.[19]
It should be emphasized that under our Constitution, the power to ratify is vested in the President, subject to the concurrence of the Senate. The role of the Senate, however, is limited only to giving or withholding its consent, or concurrence, to the ratification.[20] Hence, it is within the authority of the President to refuse to submit a treaty to the Senate or, having secured its consent for its ratification, refuse to ratify it.[21] Although the refusal of a state to ratify a treaty which has been signed in its behalf is a serious step that should not be taken lightly,[22] such decision is within the competence of the President alone, which cannot be encroached by this Court via a writ of mandamus. This Court has no jurisdiction over actions seeking to enjoin the President in the performance of his official duties.[23] The Court, therefore, cannot issue the writ of mandamus prayed for by the petitioners as it is beyond its jurisdiction to compel the executive branch of the government to transmit the signed text of Rome Statute to the Senate.

AKBAYAN vs AQUINO July 16, 2008
The privileged character of diplomatic negotiations has been recognized in this jurisdiction. In discussing valid limitations on the right to information, the Court in Chavez v. PCGG held that “information on inter-government exchanges prior to the conclusion of treaties and executive agreements may be subject to reasonable safeguards for the sake of national interest.”[23] Even earlier, the same privilege was upheld in People’s Movement for Press Freedom (PMPF) v.Manglapus[24] wherein the Court discussed the reasons for the privilege in more precise terms.

In PMPF v. Manglapus, the therein petitioners were seeking information from the President’s representatives on the state of the then on-going negotiations of the RP-US Military Bases Agreement.[25] The Court denied the petition, stressing that “secrecy of negotiations with foreign countries is not violative of the constitutional provisions of freedom of speech or of the press nor of the freedom of access to information.” The Resolution went on to state, thus:

The nature of diplomacy requires centralization of authority and expedition of decision which are inherent in executive action. Another essential characteristic of diplomacy is its confidential nature. Although much has been said about “open” and “secret” diplomacy, with disparagement of the latter, Secretaries of State Hughes and Stimsonhave clearly analyzed and justified the practice. In the words of Mr. Stimson:

“A complicated negotiation . . . cannot be carried through without many, many private talks and discussion, man to man; many tentative suggestions and proposals. Delegates from other countries come and tell you in confidence of their troubles at home and of their differences with other countries and with other delegates; they tell you of what they would do under certain circumstances and would not do under other circumstances. . . If these reports . . .should become public . . . who would ever trust American Delegations in another conference? (United States Department of State, Press Releases, June 7, 1930, pp. 282-284.).”

x x x x

There is frequent criticism of the secrecy in which negotiation with foreign powers on nearly all subjects is concerned. This, it is claimed, is incompatible with the substance of democracy. As expressed by one writer, “It can be said that there is no more rigid system of silence anywhere in the world.” (E.J. Young, Looking Behind the Censorship, J. B. Lippincott Co., 1938) President Wilson in starting his efforts for the conclusion of the World War declared that we must have “open covenants, openly arrived at.” He quickly abandoned his thought.

No one who has studied the question believes that such a method of publicity is possible. In the moment that negotiations are started, pressure groups attempt to “muscle in.” An ill-timed speech by one of the parties or a frank declaration of the concession which are exacted or offered on both sides would quickly lead to widespread propaganda to block the negotiations. After a treaty has been drafted and its terms are fully published, there is ample opportunity for discussion before it is approved. (The New American Government and Its Works, James T. Young, 4th Edition, p. 194) (Emphasis and underscoring supplied)


Still in PMPF v. Manglapus, the Court adopted the doctrine in U.S. v. Curtiss-Wright Export Corp.[26] that the President is the sole organ of the nation in its negotiations with foreign countries, viz:

“x x x In this vast external realm, with its important, complicated, delicate and manifold problems, the President alone has the power to speak or listen as a representative of the nation. He makes treaties with the advice and consent of the Senate; but he alone negotiates. Into the field of negotiation the Senate cannot intrude; and Congress itself is powerless to invade it. As Marshall said in his great argument of March 7, 1800, in the House of Representatives, “The President is the sole organ of the nation in its external relations, and its sole representative with foreign nations.” Annals, 6th Cong., col. 613. . . (Emphasis supplied; underscoring in the original)


Applying the principles adopted in PMPF v. Manglapus, it is clear that while the final text of the JPEPA may not be kept perpetually confidential – since there should be “ample opportunity for discussion before [a treaty] is approved” – the offers exchanged by the parties during the negotiations continue to be privileged even after the JPEPA is published. It is reasonable to conclude that the Japanese representatives submitted their offers with the understanding that “historic confidentiality”[27] would govern the same. Disclosing these offers could impair the ability of the Philippines to deal not only with Japan but with other foreign governments in future negotiations.

A ruling that Philippine offers in treaty negotiations should now be open to public scrutiny would discourage future Philippine representatives from frankly expressing their views during negotiations. While, on first impression, it appears wise to deter Philippine representatives from entering into compromises, it bears noting that treaty negotiations, or any negotiation for that matter, normally involve a process of quid pro quo, and oftentimes negotiators have to be willing to grant concessions in an area of lesser importance in order to obtain more favorable terms in an area of greater national interest. Apropos are the following observations of Benjamin S. Duval, Jr.:

x x x [T]hose involved in the practice of negotiations appear to be in agreement that publicity leads to “grandstanding,” tends to freeze negotiating positions, and inhibits the give-and-take essential to successful negotiation. As Sissela Bok points out, if “negotiators have more to gain from being approved by their own sides than by making a reasoned agreement with competitors or adversaries, then they are inclined to 'play to the gallery . . .'' In fact, the public reaction may leave them little option. It would be a brave, or foolish, Arab leader who expressed publicly a willingness for peace with Israel that did not involve the return of the entire West Bank, or Israeli leader who stated publicly a willingness to remove Israel's existing settlements from Judea and Samaria in return for peace.[28] (Emphasis supplied)


Indeed, by hampering the ability of our representatives to compromise, we may be jeopardizing higher national goals for the sake of securing less critical ones.
Diplomatic negotiations, therefore, are recognized as privileged in this jurisdiction, the JPEPA negotiations constituting no exception. It bears emphasis, however, that such privilege is only presumptive. For as Senate v. Ermita holds, recognizing a type of information as privileged does not mean that it will be considered privileged in all instances. Only after a consideration of the context in which the claim is made may it be determined if there is a public interest that calls for the disclosure of the desired information, strong enough to overcome its traditionally privileged status.

Vienna Convention on the Law of Treaties

The 1969 Vienna Convention on the Law of Treaties (or VCLT) codified the pre-existing customary international law on treaties, with some necessary gap-filling and clarifications. The Convention entered into force on 27 January 1980. 108 states have ratified the VCLT (May 2007); those that have not may still recognize it as binding upon them in as much as it is a restatement of customary law.
The VCLT was drafted by the International Law Commission (ILC) of the United Nations, which began work on the Convention in 1949 and finished in 1969 with a diplomatic conference held by the UN in Vienna, Austria. The Convention was adopted on 22 May 1969 and opened for signature the following day.
The scope of the Convention is limited. It applies only to treaties concluded between states, so it does not cover agreements between states and international organizations or between international organizations themselves. Nor does it apply to agreements not in written form.
The States Parties to the present Convention,
Considering the fundamental role of treaties in the history of international relations,
Recognizing the ever-increasing importance of treaties as a source of international law and as a means of developing peaceful cooperation among nations, whatever their constitutional and social systems,
Noting that the principles of free consent and of good faith and the pacta sunt servanda rule are universally recognized,
Affirming that disputes concerning treaties, like other international disputes, should be settled by peaceful means and in conformity with the principles of justice and international law,
Recalling the determination of the peoples of the United Nations to establish conditions under which justice and respect for the obligations arising from treaties can be maintained,
Having in mind the principles of international law embodied in the Charter of the United Nations, such as the principles of the equal rights and self-determination of peoples, of the sovereign equality and independence of all States, of non-interference in the domestic affairs of States, of the prohibition of the threat or use of force and of universal respect for, and observance of, human rights and fundamental freedoms for all,
Believing that the codification and progressive development of the law of treaties achieved in the present Convention will promote the purposes of the United Nations set forth in the Charter, namely, the maintenance of international peace and security, the development of friendly relations and the achievement of cooperation among nations,
Affirming that the rules of customary international law will continue to govern questions not regulated by the provisions of the present Convention,
Have agreed as follows:

(c) the intention of the State to give that effect to the signature appears from the full powers of its representative or was expressed during the negotiation.

2. For the purposes of paragraph 1:
(a) the initialling of a text constitutes a signature of the treaty when it is established that the negotiating States so agreed;
(b) the signature ad referendum of a treaty by a representative, if confirmed by his State, constitutes a full signature of the treaty.

Article 13
Consent to be bound by a treaty expressed by an exchange of instruments constituting a treaty

The consent of States to be bound by a treaty constituted by instruments exchanged between them is expressed by that exchange when:
(a) the instruments provide that their exchange shall have that effect; or

Article 16
Exchange or deposit of instruments of ratification, acceptance, approval or accession

Unless the treaty otherwise provides, instruments of ratification, acceptance, approval or accession establish the consent of a State to be bound by a treaty upon:
(a) their exchange between the contracting States;
(b) their deposit with the depositary; or
(c) their notification to the contracting States or to the depositary, if so agreed.

Article 17
Consent to be bound by part of a treaty and choice of differing provisions

1. Without prejudice to articles 19 to 23, the consent of a State to be bound by part of a treaty is effective only if the treaty so permits or the other contracting States so agree.

2. The consent of a State to be bound by a treaty which permits a choice between differing provisions is effective only if it is made clear to which of the provisions the consent relates.

Article 18
Obligation not to defeat the object and purpose of a treaty prior to its entry into force

A State is obliged to refrain from acts which would defeat the object and purpose of a treaty when:
(a) it has signed the treaty or has exchanged instruments constituting the treaty subject to ratification, acceptance or approval, until it shall have made its intention clear not to become a party to the treaty; or
(b) it has expressed its consent to be bound by the treaty, pending the entry into force of the treaty and provided that such entry into force is not unduly delayed.

SECTION 2. RESERVATIONS

Article 19
Formulation of reservations

A State may, when signing, ratifying, accepting, approving or acceding to a treaty, formulate a reservation unless:
(a) the reservation is prohibited by the treaty;
(b) the treaty provides that only specified reservations, which do not include the reservation in question, may be made; or
(c) in cases not falling under sub-paragraphs (a) and (b), the reservation is incompatible with the object and purpose of the treaty.

Article 20
Acceptance of and objection to reservations

1. A reservation expressly authorized by a treaty does not require any subsequent acceptance by the other contracting States unless the treaty so provides.

2. When it appears from the limited number of the negotiating States and the object and purpose of a treaty that the application of the treaty in its entirety between all the parties is an essential condition of the consent of each one to be bound by the treaty, a reservation requires acceptance by all the parties.

3. When a treaty is a constituent instrument of an international organization and unless it otherwise provides, a reservation requires the acceptance of the competent organ of that organization.

4. In cases not falling under the preceding paragraphs and unless the treaty otherwise provides:
(a) acceptance by another contracting State of a reservation constitutes the reserving State a party to the treaty in relation to that other State if or when the treaty is in force for those States;
(b) an objection by another contracting State to a reservation does not preclude the entry into force of the treaty as between the objecting and reserving States unless a contrary intention is definitely expressed by the objecting State;
(c) an act expressing a State's consent to be bound by the treaty and containing a reservation is effective as soon as at least one other contracting State has accepted the reservation.

5. For the purposes of paragraphs 2 and 4 and unless the treaty otherwise provides, a reservation is considered to have been accepted by a State if it shall have raised no objection to the reservation by the end of a period of twelve months after it was notified of the reservation or by the date on which it expressed its consent to be bound by the treaty, whichever is later.

Article 21
Legal effects of reservations and of objections to reservations

1. A reservation established with regard to another party in accordance with articles 19, 20 and 23:
(a) modifies for the reserving State in its relations with that other party the provisions of the treaty to which the reservation relates to the extent of the reservation; and
(b) modifies those provisions to the same extent for that other party in its relations with the reserving State.

2. The reservation does not modify the provisions of the treaty for the other parties to the treaty inter se.

3. When a State objecting to a reservation has not opposed the entry into force of the treaty between itself and the reserving State, the provisions to which the reservation relates do not apply as between the two States to the extent of the reservation.

Article 22
Withdrawal of reservations and of objections to reservations

1. Unless the treaty otherwise provides, a reservation may be withdrawn at any time and the consent of a State which has accepted the reservation is not required for its withdrawal.

2. Unless the treaty otherwise provides, an objection to a reservation may be withdrawn at any time.

3. Unless the treaty otherwise provides, or it is otherwise agreed:
(a) the withdrawal of a reservation becomes operative in relation to another contracting State only when notice of it has been received by that State;
(b) the withdrawal of an objection to a reservation becomes operative only when notice of it has been received by the State which formulated the reservation.

Article 23
Procedure regarding reservations

1. A reservation, an express acceptance of a reservation and an objection to a reservation must be formulated in writing and communicated to the contracting States and other States entitled to become parties to the treaty.

2. If formulated when signing the treaty subject to ratification, acceptance or approval, a reservation must be formally confirmed by the reserving State when expressing its consent to be bound by the treaty. In such a case the reservation shall be considered as having been made on the date of its confirmation.

3. An express acceptance of, or an objection to, a reservation made previously to confirmation of the reservation does not itself require confirmation.

4. The withdrawal of a reservation or of an objection to a reservation must be formulated in writing.

SECTION 3. ENTRY INTO FORCE AND PROVISIONAL APPLICATION OF TREATIES

Article 24
Entry into force

1. A treaty enters into force in such manner and upon such date as it may provide or as the negotiating States may agree.

2. Failing any such provision or agreement, a treaty enters into force as soon as consent to be bound by the treaty has been established for all the negotiating States.

3. When the consent of a State to be bound by a treaty is established on a date after the treaty has come into force, the treaty enters into force for that State on that date, unless the treaty otherwise provides.

4. The provisions of a treaty regulating the authentication of its text, the establishment of the consent of States to be bound by the treaty, the manner or date of its entry into force, reservations, the functions of the depositary and other matters arising necessarily before the entry into force of the treaty apply from the time of the adoption of its text.

Article 25
Provisional application

1. A treaty or a part of a treaty is applied provisionally pending its entry into force if:
(a) the treaty itself so provides; or
(b) the negotiating States have in some other manner so agreed.

2. Unless the treaty otherwise provides or the negotiating States have otherwise agreed, the provisional application of a treaty or a part of a treaty with respect to a State shall be terminated if that State notifies the other States between which the treaty is being applied provisionally of its intention not to become a party to the treaty.

Pacta sunt servanda

Every treaty in force is binding upon the parties to it and must be performed by them in good faith.

SECTION 2. APPLICATION OF TREATIES

Article 28
Non-retroactivity of treaties

Unless a different intention appears from the treaty or is otherwise established, its provisions do not bind a party in relation to any act or fact which took place or any situation which ceased to exist before the date of the entry into force of the treaty with respect to that party.

Article 29
Territorial scope of treaties

Unless a different intention appears from the treaty or is otherwise established, a treaty is binding upon each party in respect of its entire territory.

Article 30
Application of successive treaties relating to the same subject-matter

1. Subject to Article 103 of the Charter of the United Nations, the rights and obligations of States parties to successive treaties relating to the same subject-matter shall be determined in accordance with the following paragraphs.

2. When a treaty specifies that it is subject to, or that it is not to be considered as incompatible with, an earlier or later treaty, the provisions of that other treaty prevail.

3. When all the parties to the earlier treaty are parties also to the later treaty but the earlier treaty is not terminated or suspended in operation under article 59, the earlier treaty applies only to the extent that its provisions are compatible with those of the latter treaty.

4. When the parties to the later treaty do not include all the parties to the earlier one:
(a) as between States parties to both treaties the same rule applies as in paragraph 3;
(b) as between a State party to both treaties and a State party to only one of the treaties, the treaty to which both States are parties governs their mutual rights and obligations.

5. Paragraph 4 is without prejudice to article 41, or to any question of the termination or suspension of the operation of a treaty under article 60 or to any question of responsibility which may arise for a State from the conclusion or application of a treaty the provisions of which are incompatible with its obligations towards another State under another treaty.

SECTION 3. INTERPRETATION OF TREATIES

Article 31
General rule of interpretation

1. A treaty shall be interpreted in good faith in accordance with the ordinary meaning to be given to the terms of the treaty in their context and in the light of its object and purpose.

(a) any agreement relating to the treaty which was made between all the parties in connection with the conclusion of the treaty;
(b) any instrument which was made by one or more parties in connection with the conclusion of the treaty and accepted by the other parties as an instrument related to the treaty.

3. There shall be taken into account, together with the context:
(a) any subsequent agreement between the parties regarding the interpretation of the treaty or the application of its provisions;
(b) any subsequent practice in the application of the treaty which establishes the agreement of the parties regarding its interpretation;
(c) any relevant rules of international law applicable in the relations between the parties.

4. A special meaning shall be given to a term if it is established that the parties so intended.

Article 32
Supplementary means of interpretation

Recourse may be had to supplementary means of interpretation, including the preparatory work of the treaty and the circumstances of its conclusion, in order to confirm the meaning resulting from the application of article 31, or to determine the meaning when the interpretation according to article 31:
(a) leaves the meaning ambiguous or obscure; or
(b) leads to a result which is manifestly absurd or unreasonable.

Article 33
Interpretation of treaties authenticated in two or more languages

1. When a treaty has been authenticated in two or more languages, the text is equally authoritative in each language, unless the treaty provides or the parties agree that, in case of divergence, a particular text shall prevail.

2. A version of the treaty in a language other than one of those in which the text was authenticated shall be considered an authentic text only if the treaty so provides or the parties so agree.

3. The terms of the treaty are presumed to have the same meaning in each authentic text.

4. Except where a particular text prevails in accordance with paragraph 1, when a comparison of the authentic texts discloses a difference of meaning which the application of articles 31 and 32 does not remove, the meaning which best reconciles the texts, having regard to the object and purpose of the treaty, shall be adopted.

SECTION 4. TREATIES AND THIRD STATES

Article 34
General rule regarding third States

A treaty does not create either obligations or rights for a third State without its consent.

Article 35
Treaties providing for obligations for third States

An obligation arises for a third State from a provision of a treaty if the parties to the treaty intend the provision to be the means of establishing the obligation and the third State expressly accepts that obligation in writing.

Article 36
Treaties providing for rights for third States

1. A right arises for a third State from a provision of a treaty if the parties to the treaty intend the provision to accord that right either to the third State, or to a group of States to which it belongs, or to all States, and the third State assents thereto. Its assent shall be presumed so long as the contrary is not indicated, unless the treaty otherwise provides.

2. A State exercising a right in accordance with paragraph 1 shall comply with the conditions for its exercise provided for in the treaty or established in conformity with the treaty.

Article 37
Revocation or modification of obligations or rights of third States

1. When an obligation has arisen for a third State in conformity with article 35, the obligation may be revoked or modified only with the consent of the parties to the treaty and of the third State, unless it is established that they had otherwise agreed.

2. When a right has arisen for a third State in conformity with article 36, the right may not be revoked or modified by the parties if it is established that the right was intended not to be revocable or subject to modification without the consent of the third State.

Article 38
Rules in a treaty becoming binding on third States through international custom

Nothing in articles 34 to 37 precludes a rule set forth in a treaty from becoming binding upon a third State as a customary rule of international law, recognized as such.
.
+ Part IV: Amendment and Modification of Treaties
.
Article 39
General rule regarding the amendment of treaties

A treaty may be amended by agreement between the parties. The rules laid down in Part II apply to such an agreement except in so far as the treaty may otherwise provide.

Article 40
Amendment of multilateral treaties

1. Unless the treaty otherwise provides, the amendment of multilateral treaties shall be governed by the following paragraphs.

2. Any proposal to amend a multilateral treaty as between all the parties must be notified to all the contracting States, each one of which shall have the right to take part in:

(b) the negotiation and conclusion of any agreement for the amendment of the treaty.

3. Every State entitled to become a party to the treaty shall also be entitled to become a party to the treaty as amended.

4. The amending agreement does not bind any State already a party to the treaty which does not become a party to the amending agreement; article 30, paragraph 4(b), applies in relation to such State.

5. Any State which becomes a party to the treaty after the entry into force of the amending agreement shall, failing an expression of a different intention by that State:
(a) be considered as a party to the treaty as amended; and
(b) be considered as a party to the unamended treaty in relation to any party to the treaty not bound by the amending agreement.

Article 41
Agreements to modify multilateral treaties between certain of the parties only

1. Two or more of the parties to a multilateral treaty may conclude an agreement to modify the treaty as between themselves alone if:
(a) the possibility of such a modification is provided for by the treaty; or
(b) the modification in question is not prohibited by the treaty and:
- (i) does not affect the enjoyment by the other parties of their rights under the treaty or the performance of their obligations;
- (ii) does not relate to a provision, derogation from which is incompatible with the effective execution of the object and purpose of the treaty as a whole.

+ Part V: Invalidity, Termination and Suspension of the Operation of Treaties
.
SECTION 1. GENERAL PROVISIONS

Article 42
Validity and continuance in force of treaties

1. The validity of a treaty or of the consent of a State to be bound by a treaty may be impeached only through the application of the present Convention.

2. The termination of a treaty, its denunciation or the withdrawal of a party, may take place only as a result of the application of the provisions of the treaty or of the present Convention. The same rule applies to suspension of the operation of a treaty.

Article 43
Obligations imposed by international law independently of a treaty

The invalidity, termination or denunciation of a treaty, the withdrawal of a party from it, or the suspension of its operation, as a result of the application of the present Convention or of the provisions of the treaty, shall not in any way impair the duty of any State to fulfil any obligation embodied in the treaty to which it would be subject under international law independently of the treaty.

Article 44
Separability of treaty provisions

1. A right of a party, provided for in a treaty or arising under article 56, to denounce, withdraw from or suspend the operation of the treaty may be exercised only with respect to the whole treaty unless the treaty otherwise provides or the parties otherwise agree.

2. A ground for invalidating, terminating, withdrawing from or suspending the operation of a treaty recognized in the present Convention may be invoked only with respect to the whole treaty except as provided in the following paragraphs or in article 60.

3. If the ground relates solely to particular clauses, it may be invoked only with respect to those clauses where:
(a) the said clauses are separable from the remainder of the treaty with regard to their application;
(b) it appears from the treaty or is otherwise established that acceptance of those clauses was not an essential basis of the consent of the other party or parties to be bound by the treaty as a whole; and
(c) continued performance of the remainder of the treaty would not be unjust.

4. In cases falling under articles 49 and 50 the State entitled to invoke the fraud or corruption may do so with respect either to the whole treaty or, subject to paragraph 3, to the particular clauses alone.

5. In cases falling under articles 51, 52 and 53, no separation of the provisions of the treaty is permitted.

Article 45
Loss of a right to invoke a ground for invalidating, terminating, withdrawing from or suspending the operation of a treaty

A State may no longer invoke a ground for invalidating, terminating, withdrawing from or suspending the operation of a treaty under articles 46 to 50 or articles 60 and 62 if, after becoming aware of the facts:
(a) it shall have expressly agreed that the treaty is valid or remains in force or continues in operation, as the case may be; or
(b) it must by reason of its conduct be considered as having acquiesced in the validity of the treaty or in its maintenance in force or in operation, as the case may be.

SECTION 2. INVALIDITY OF TREATIES

Article 46
Provisions of internal law regarding competence to conclude treaties

1. A State may not invoke the fact that its consent to be bound by a treaty has been expressed in violation of a provision of its internal law regarding competence to conclude treaties as invalidating its consent unless that violation was manifest and concerned a rule of its internal law of fundamental importance.

2. A violation is manifest if it would be objectively evident to any State conducting itself in the matter in accordance with normal practice and in good faith.

Article 47
Specific restrictions on authority to express the consent of a State

If the authority of a representative to express the consent of a State to be bound by a particular treaty has been made subject to a specific restriction, his omission to observe that restriction may not be invoked as invalidating the consent expressed by him unless the restriction was notified to the other negotiating States prior to his expressing such consent.

Article 48
Error

1. A State may invoke an error in a treaty as invalidating its consent to be bound by the treaty if the error relates to a fact or situation which was assumed by that State to exist at the time when the treaty was concluded and formed an essential basis of its consent to be bound by the treaty.

2. Paragraph 1 shall not apply if the State in question contributed by its own conduct to the error or if the circumstances were such as to put that State on notice of a possible error.

3. An error relating only to the wording of the text of a treaty does not affect its validity; article 79 then applies.

Article 49
Fraud

If a State has been induced to conclude a treaty by the fraudulent conduct of another negotiating State, the State may invoke the fraud as invalidating its consent to be bound by the treaty.

Article 50
Corruption of a representative of a State

If the expression of a State's consent to be bound by a treaty has been procured through the corruption of its representative directly or indirectly by another negotiating State, the State may invoke such corruption as invalidating its consent to be bound by the treaty.

Article 51
Coercion of a representative of a State

The expression of a State's consent to be bound by a treaty which has been procured by the coercion of its representative through acts or threats directed against him shall be without any legal effect.

Article 52
Coercion of a State by the threat or use of force

A treaty is void if its conclusion has been procured by the threat or use of force in violation of the principles of international law embodied in the Charter of the United Nations.

Article 53
Treaties conflicting with a peremptory norm of general international law (jus cogens)

A treaty is void if, at the time of its conclusion, it conflicts with a peremptory norm of general international law. For the purposes of the present Convention, a peremptory norm of general international law is a norm accepted and recognized by the international community of States as a whole as a norm from which no derogation is permitted and which can be modified only by a subsequent norm of general international law having the same character.

SECTION 3. TERMINATION AND SUSPENSION OF THE OPERATION OF TREATIES

Article 54
Termination of or withdrawal from a treaty under its provisions or by consent of the parties

The termination of a treaty or the withdrawal of a party may take place:

(b) at any time by consent of all the parties after consultation with the other contracting States.

Article 55
Reduction of the parties to a multilateral treaty below the number necessary for its entry into force

Unless the treaty otherwise provides, a multilateral treaty does not terminate by reason only of the fact that the number of the parties falls below the number necessary for its entry into force.

Article 56
Denunciation of or withdrawal from a treaty containing no provision regarding termination, denunciation or withdrawal

1. A treaty which contains no provision regarding its termination and which does not provide for denunciation or withdrawal is not subject to denunciation or withdrawal unless:

Article 57
Suspension of the operation of a treaty under its provisions or by consent of the parties

The operation of a treaty in regard to all the parties or to a particular party may be suspended:
(a) in conformity with the provisions of the treaty; or
(b) at any time by consent of all the parties after consultation with the other contracting States.

Article 58
Suspension of the operation of a multilateral treaty by agreement between certain of the parties only

1. Two or more parties to a multilateral treaty may conclude an agreement to suspend the operation of provisions of the treaty, temporarily and as between themselves alone, if:
(a) the possibility of such a suspension is provided for by the treaty; or
(b) the suspension in question is not prohibited by the treaty and:
- (i) does not affect the enjoyment by the other parties of their rights under the treaty or the performance of their obligations;
- (ii) is not incompatible with the object and purpose of the treaty.

2. Unless in a case falling under paragraph 1(a) the treaty otherwise provides, the parties in question shall notify the other parties of their intention to conclude the agreement and of those provisions of the treaty the operation of which they intend to suspend.

Article 59
Termination or suspension of the operation of a treaty implied by conclusion of a later treaty

1. A treaty shall be considered as terminated if all the parties to it conclude a later treaty relating to the same subject-matter and:
(a) it appears from the later treaty or is otherwise established that the parties intended that the matter should be governed by that treaty; or
(b) the provisions of the later treaty are so far incompatible with those of the earlier one that the two treaties are not capable of being applied at the same time.

2. The earlier treaty shall be considered as only suspended in operation if it appears from the later treaty or is otherwise established that such was the intention of the parties.

Article 60
Termination or suspension of the operation of a treaty as a consequence of its breach

1. A material breach of a bilateral treaty by one of the parties entitles the other to invoke the breach as a ground for terminating the treaty or suspending its operation in whole or in part.

2. A material breach of a multilateral treaty by one of the parties entitles:
(a) the other parties by unanimous agreement to suspend the operation of the treaty in whole or in part or to terminate it either:
- (i) in the relations between themselves and the defaulting State, or
- (ii) as between all the parties;
(b) a party specially affected by the breach to invoke it as a ground for suspending the operation of the treaty in whole or in part in the relations between itself and the defaulting State;
(c) any party other than the defaulting State to invoke the breach as a ground for suspending the operation of the treaty in whole or in part with respect to itself if the treaty is of such a character that a material breach of its provisions by one party radically changes the position of every party with respect to the further performance of its obligations under the treaty.

3. A material breach of a treaty, for the purposes of this article, consists in:
(a) a repudiation of the treaty not sanctioned by the present Convention; or
(b) the violation of a provision essential to the accomplishment of the object or purpose of the treaty.

4. The foregoing paragraphs are without prejudice to any provision in the treaty applicable in the event of a breach.

5. Paragraphs 1 to 3 do not apply to provisions relating to the protection of the human person contained in treaties of a humanitarian character, in particular to provisions prohibiting any form of reprisals against persons protected by such treaties.

Article 61
Supervening impossibility of performance

1. A party may invoke the impossibility of performing a treaty as a ground for terminating or withdrawing from it if the impossibility results from the permanent disappearance or destruction of an object indispensable for the execution of the treaty. If the impossibility is temporary, it may be invoked only as a ground for suspending the operation of the treaty.

2. Impossibility of performance may not be invoked by a party as a ground for terminating, withdrawing from or suspending the operation of a treaty if the impossibility is the result of a breach by that party either of an obligation under the treaty or of any other international obligation owed to any other party to the treaty.

Article 62
Fundamental change of circumstances

1. A fundamental change of circumstances which has occurred with regard to those existing at the time of the conclusion of a treaty, and which was not foreseen by the parties, may not be invoked as a ground for terminating or withdrawing from the treaty unless:
(a) the existence of those circumstances constituted an essential basis of the consent of the parties to be bound by the treaty; and
(b) the effect of the change is radically to transform the extent of obligations still to be performed under the treaty.

2. A fundamental change of circumstances may not be invoked as a ground for terminating or withdrawing from a treaty:
(a) if the treaty establishes a boundary; or
(b) if the fundamental change is the result of a breach by the party invoking it either of an obligation under the treaty or of any other international obligation owed to any other party to the treaty.

3. If, under the foregoing paragraphs, a party may invoke a fundamental change of circumstances as a ground for terminating or withdrawing from a treaty it may also invoke the change as a ground for suspending the operation of the treaty.

Article 63
Severance of diplomatic or consular relations

The severance of diplomatic or consular relations between parties to a treaty does not affect the legal relations established between them by the treaty except in so far as the existence of diplomatic or consular relations is indispensable for the application of the treaty.

Article 64
Emergence of a new peremptory norm of general international law (jus cogens)

If a new peremptory norm of general international law emerges, any existing treaty which is in conflict with that norm becomes void and terminates.

SECTION 4. PROCEDURE

Article 65
Procedure to be followed with respect to invalidity, termination, withdrawal from or suspension of the operation of a treaty

1. A party which, under the provisions of the present Convention, invokes either a defect in its consent to be bound by a treaty or a ground for impeaching the validity of a treaty, terminating it, withdrawing from it or suspending its operation, must notify the other parties of its claim. The notification shall indicate the measure proposed to be taken with respect to the treaty and the reasons therefor.

2. If, after the expiry of a period which, except in cases of special urgency, shall not be less than three months after the receipt of the notification, no party has raised any objection, the party making the notification may carry out in the manner provided in article 67 the measure which it has proposed.

3. If, however, objection has been raised by any other party, the parties shall seek a solution through the means indicated in article 33 of the Charter of the United Nations.

4. Nothing in the foregoing paragraphs shall affect the rights or obligations of the parties under any provisions in force binding the parties with regard to the settlement of disputes.

5. Without prejudice to article 45, the fact that a State has not previously made the notification prescribed in paragraph 1 shall not prevent it from making such notification in answer to another party claiming performance of the treaty or alleging its violation.

Article 66
Procedures for judicial settlement, arbitration and conciliation

If, under paragraph 3 of article 65, no solution has been reached within a period of 12 months following the date on which the objection was raised, the following procedures shall be followed:
(a) any one of the parties to a dispute concerning the application or the interpretation of articles 53 or 64 may, by a written application, submit it to the International Court of Justice for a decision unless the parties by common consent agree to submit the dispute to arbitration;
(b) any one of the parties to a dispute concerning the application or the interpretation of any of the other articles in Part V of the present Convention may set in motion the procedure specified in the Annex to the Convention by submitting a request to that effect to the Secretary-General of the United Nations.

SECTION 5. CONSEQUENCES OF THE INVALIDITY, TERMINATION OR SUSPENSION OF THE OPERATION OF A TREATY

Article 69
Consequences of the invalidity of a treaty

1. A treaty the invalidity of which is established under the present Convention is void. The provisions of a void treaty have no legal force.

2. If acts have nevertheless been performed in reliance on such a treaty:
(a) each party may require any other party to establish as far as possible in their mutual relations the position that would have existed if the acts had not been performed;
(b) acts performed in good faith before the invalidity was invoked are not rendered unlawful by reason only of the invalidity of the treaty.

3. In cases falling under articles 49, 50, 51 or 52, paragraph 2 does not apply with respect to the party to which the fraud, the act of corruption or the coercion is imputable.

4. In the case of the invalidity of a particular State's consent to be bound by a multilateral treaty, the foregoing rules apply in the relations between that State and the parties to the treaty.

Article 70
Consequences of the termination of a treaty

1. Unless the treaty otherwise provides or the parties otherwise agree, the termination of a treaty under its provisions or in accordance with the present Convention:
(a) releases the parties from any obligation further to perform the treaty;
(b) does not affect any right, obligation or legal situation of the parties created through the execution of the treaty prior to its termination.

2. If a State denounces or withdraws from a multilateral treaty, paragraph 1 applies in the relations between that State and each of the other parties to the treaty from the date when such denunciation or withdrawal takes effect.

Article 71
Consequences of the invalidity of a treaty which conflict with a peremptory norm of general international law

1. In the case of a treaty which is void under article 53 the parties shall:
(a) eliminate as far as possible the consequences of any act performed in reliance on any provision which conflicts with the peremptory norm of general international law; and
(b) bring their mutual relations into conformity with the peremptory norm of general international law.

2. In the case of a treaty which becomes void and terminates under article 64, the termination of the treaty:
(a) releases the parties from any obligation further to perform the treaty;
(b) does not affect any right, obligation or legal situation of the parties created through the execution of the treaty prior to its termination; provided that those rights, obligations or situations may thereafter be maintained only to the extent that their maintenance is not in itself in conflict with the new peremptory norm of general international law.

Article 72
Consequences of the suspension of the operation of a treaty

1. Unless the treaty otherwise provides or the parties otherwise agree, the suspension of the operation of a treaty under its provisions or in accordance with the present Convention:
(a) releases the parties between which the operation of the treaty is suspended from the obligation to perform the treaty in their mutual relations during the period of the suspension;
(b) does not otherwise affect the legal relations between the parties established by the treaty.

2. During the period of the suspension the parties shall refrain from acts tending to obstruct the resumption of the operation of the treaty.

Article 73
Cases of State succession, State responsibility and outbreak of hostilities

The provisions of the present Convention shall not prejudge any question that may arise in regard to a treaty from a succession of States or from the international responsibility of a State or from the outbreak of hostilities between States.

Article 74
Diplomatic and consular relations and the conclusion of treaties

The severance or absence of diplomatic or consular relations between two or more States does not prevent the conclusion of treaties between those States. The conclusion of a treaty does not in itself affect the situation in regard to diplomatic or consular relations.

Article 75
Case of an aggressor State

The provisions of the present Convention are without prejudice to any obligation in relation to a treaty which may arise for an aggressor State in consequence of measures taken in conformity with the Charter of the United Nations with reference to that State's aggression.
