Origin of the Conception
How did this distinctive feature of the Constitution come about, by virtue of which the treaty-making authority is enabled to stamp upon its promises the quality of municipal law, thereby rendering them "self-executory," as it is said; in other words, enforceable by the courts? The answer is that article VI, paragraph 2 was, at its inception, an outgrowth of a major weakness of the Articles of Confederation. Although the Articles entrusted the treaty-making power to Congress, fulfillment of Congress' promises was dependent on the State legislatures. The result was that two highly important Articles of the Treaty of Peace of 1783 not only went unenforced, but were in some instances directly flouted by the local legislatures. These were articles IV and VI, which contained stipulations in favor, respectively, of British creditors of American citizens and of the former Loyalists; in short of private persons. Confronted with the reiterated protests of the British government, John Jay, Secretary of the United States for Foreign Affairs, suggested to Congress late in 1786 that it request the State legislatures to repeal all legislation repugnant to the Treaty of Peace, and at the same time authorize their courts in all cases arising from the said treaty to decide and adjudge according to the true intent and meaning of the same, "anything in the said acts * * * to the contrary notwithstanding." On April 13, 1787 Congress unanimously voted Jay's proposal, which on the eve of the assembling of the Federal Convention was transmitted to the State legislatures, by seven of which it was promptly adopted.[155]
TREATY RIGHTS VERSUS STATE POWER
The first case to arise under article VI, clause 2, was Ware v. Hylton.[156] The facts and bearing of the decision are indicated in the syllabus: "A debt, due before the war from an American to a British subject, was during the war, paid into the loan office of Virginia, in pursuance of a law of that State of the 20th of December, 1777, sequestering British property and providing that such payment, and a receipt therefor, should discharge the debt. Held: That the legislature of Virginia which from the 4th of July, 1776, and before the Confederation of the United States, * * * possessed and exercised all the rights of independent governments, had authority to make such law and that the same was obligatory, since every nation at war with another may confiscate all property of, including private debts due, the enemy. Such payment and discharge would therefore be a bar to a subsequent action, unless the creditor's right was revived by the treaty of peace, by which alone the restitution of, or compensation for, British property confiscated during the war by any of the United States could only be provided for. Held, that the fourth article of the treaty of peace between Great Britain and the United States, of September 3, 1783, nullifies said law of Virginia, destroys the payment made under it, and revives the debt, and gives a right of recovery against the principal debtor, notwithstanding such payment thereof, under the authority of State law." In Hopkirk v. Bell[157] the Court further held that this same treaty provision prevented the operation of a Virginia statute of limitation to bar collection of antecedent debts. In numerous subsequent cases the Court invariably ruled that treaty provisions supersede inconsistent State laws governing the right of aliens to inherit real estate.[158] Such a case was Hauenstein v. Lynham,[159] in which the Court upheld the right of a citizen of the Swiss Republic, under the treaty of 1850 with that country, to recover the estate of a relative dying intestate in Virginia, to sell the same and to export the proceeds from the sale.[160]
Certain more recent cases stem from California legislation, most of it directed against Japanese immigrants. A statute which excluded aliens ineligible to American citizenship from owning real estate was upheld in 1923 on the ground that the treaty in question did not secure the rights claimed.[161] But in Oyama v. California,[162] decided in 1948, a majority of the Court indicated a strongly held opinion that this legislation conflicted with the equal protection clause of Amendment XIV, a view which has since received the endorsement of the California Supreme Court by a narrow majority.[163] Meantime, California was informed that the rights of German nationals, under the Treaty of December 8, 1923 between the United States and the Reich, to whom real property in the United States had descended or been devised, to dispose of it, had survived the recent war and certain war legislation, and accordingly prevailed over conflicting State legislation.[164]
WHEN IS A TREATY SELF-EXECUTING?
What is the scope of the power of American courts under article VI, clause 2, to lend ear to private claims based on treaty provisions, on the ground that such provisions are self-executing? Jay had in mind certain intended victims of State legislation; and in fact the cases reviewed above all arose within the normal field of State legislative power. Nevertheless, as early as 1801, in United States v. Schooner Peggy,[165] the Supreme Court, speaking by Chief Justice Marshall, took notice of a treaty with France, executed after a court of admiralty had entered a final judgment condemning a captured French vessel, and finding it applicable to the situation before it, set the judgment aside and ordered the vessel restored to her owners. Since that time the Court has declared repeatedly in cases in which State law was not involved that when a treaty prescribes a rule by which private rights are to be determined, the courts are bound to take judicial notice thereof and to accept it as a rule of decision in any appropriate proceeding to enforce such rights.[166] In short, whether a given treaty provision is self-executing is a question for the Court; although it does not altogether lack guiding principles in deciding it, the most important of which is the doctrine of political questions.[167] See pp. [426], [471-472].
CONSTITUTIONAL FREEDOM OF CONGRESS WITH RESPECT TO TREATIES
From the foregoing two other questions arise: first, are there types of treaty provisions which only Congress can put into effect? Second, assuming an affirmative answer to the above question, is Congress under constitutional obligation to supply such implementation? For such answer as exists to the first question resort must be had to the record of practice and nonjudicial opinion. The question arose originally in 1796 in connection with the Jay Treaty, certain provisions of which required appropriations to carry them into effect. In view of the third clause of article I, section 9 of the Constitution, which says that "no money shall be drawn from the Treasury, but in Consequence of Appropriations made by law; * * *," it was universally agreed that Congress must be applied to if the treaty provisions alluded to were to be put into execution. But at this point the second question arose, to the solution of which the Court has subsequently contributed indirectly. (See pp. [420-421]). A bill being introduced into the House of Representatives to vote the needed funds, supporters of the treaty, Hamilton, Chief Justice Ellsworth, and others, argued that the House must make the appropriation willy nilly; that the treaty, having been ratified by and with the advice and consent of the Senate, was "supreme law of the land," and that the legislative branch was bound thereby no less than the executive and judicial branches.[168] Madison, a member of the House, opposed this thesis in a series of resolutions, the nub of which is comprised in the following statement: "When a Treaty stipulates regulations on any of the subjects submitted by the Constitution to the power of Congress, it must depend for its execution, as to such stipulations, on a law or laws to be passed by Congress. And it is the Constitutional right and duty of the House of Representatives, in all such cases, to deliberate on the expediency or inexpediency of carrying such Treaty into effect, and to determine and act thereon, as, in their judgment, may be most conducive to the public good."[169] The upshot of the matter was that the House adopted Madison's resolutions, while at the same time voting the required funds.[170]
