2. ABAYA vs. EBDANE, G.R. No. 167919
February 14, 2007

Supreme Court Ruling

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,69 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.

3. DEPARTMENT of BUDGET and MANAGEMENT PROCUREMENT SERVICE vs. KOLONWEL TRADING,
G.R. No. 175616, June 8, 2007

Supreme Court Ruling

Under the fundamental international law principle of pacta sunt servanda, [36] 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.


4. BAYAN vs. EXEC. SEC. ZAMORA, G.R. No. 138570.
January 25, 2000

Supreme Court Ruling

This Court is of the firm view that the phrase “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.

Well-entrenched is the principle that the words used in the Constitution are to be given their ordinary meaning except where technical terms are employed, in which case the significance thus attached to them prevails. Its language should be understood in the sense they have in common use.

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.[35] 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.


5. COMMISSIONER OF INTERNAL REVENUE vs. S.C. JOHNSON AND SON,INC., G.R. No. 127105 June 25, 1999

Supreme Court Ruling

The phrase "paid under similar circumstances in Article 13 (2) (b), (iii) of the RP-US Tax Treaty should be interpreted to refer to payment of royalty, and not to the payment of the tax, for the reason that the phrase "paid under similar circumstances" is followed by the phrase "to a resident of a third state". The respondent court held that "Words are to be understood in the context in which they are used", and since what is paid to a resident of a third state is not a tax but a royalty "logic instructs" that the treaty provision in question should refer to royalties of the same kind paid under similar circumstances.

The above construction is based principally on syntax or sentence structure but fails to take into account the purpose animating the treaty provisions in point. To begin with, we are not aware of any law or rule pertinent to the payment of royalties, and none has been brought to our attention, which provides for the payment of royalties under dissimilar circumstances. The tax rates on royalties and the circumstances of payment thereof are the same for all the recipients of such royalties and there is no disparity based on nationality in the circumstances of such payment.6 On the other hand, a cursory reading of the various tax treaties will show that there is no similarity in the provisions on relief from or avoidance of double taxation7 as this is a matter of negotiation between the contracting parties.

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. 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. 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. 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. 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.

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.

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.

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.

6. AKBAYAN vs. Aquino, G.R. No. 170516
July 16, 2008

Supreme Court Ruling

By constitutional fiat and by the intrinsic nature of his office, the President, as head of State, is the sole organ and authority in the external affairs of the country. In many ways, the President is the chief architect of the nation's foreign policy; his "dominance in the field of foreign relations is (then) conceded." Wielding vast powers and influence, his conduct in the external affairs of the nation, as Jefferson describes, is “executive altogether.”

As regards the power to enter into treaties or international agreements, the Constitution vests the same in the President, subject only to the concurrence of at least two thirds vote of all the members of the Senate. In this light, the negotiation of the VFA and the subsequent ratification of the agreement are exclusive acts which pertain solely to the President, in the lawful exercise of his vast executive and diplomatic powers granted him no less than by the fundamental law itself. Into the field of negotiation the Senate cannot intrude, and Congress itself is powerless to invade it.

While the power then to fix tariff rates and other taxes clearly belongs to Congress, and is exercised by the President only by delegation of that body, it has long been recognized that the power to enter into treaties is vested directly and exclusively in the President, subject only to the concurrence of at least two-thirds of all the Members of the Senate for the validity of the treaty. In this light, the authority of the President to enter into trade agreements with foreign nations provided under P.D. 1464 may be interpreted as an acknowledgment of a power already inherent in its office. It may not be used as basis to hold the President or its representatives accountable to Congress for the conduct of treaty negotiations.

7. PIMENTEL vs. EXECUTIVE SECRETARY, G.R. No. 158088
July 6, 2005

Supreme Court Ruling

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.


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.
