DETERMINATION WHETHER A TREATY HAS LAPSED
At the same time, there is clear judicial recognition that the President may without consulting Congress validly determine the question whether specific treaty provisions have lapsed. The following passage from Justice Lurton's opinion in Charlton v. Kelly[188] is pertinent: "If the attitude of Italy was, as contended, a violation of the obligation of the treaty, which, in international law, would have justified the United States in denouncing the treaty as no longer obligatory, it did not automatically have that effect. If the United States elected not to declare its abrogation, or come to a rupture, the treaty would remain in force. It was only voidable, not void; and if the United States should prefer, it might waive any breach which in its judgment had occurred and conform to its own obligation as if there had been no such breach. * * * That the political branch of the Government recognizes the treaty obligation as still existing is evidenced by its action in this case. * * * The executive department having thus elected to waive any right to free itself from the obligation to deliver up its own citizens, it is the plain duty of this court to recognize the obligation to surrender the appellant as one imposed by the treaty as the supreme law of the land as affording authority for the warrant of extradition."[189] So also it is primarily for the political departments to determine whether certain provisions of a treaty have survived a war in which the other contracting state ceased to exist as a member of the international community.[190]
STATUS OF A TREATY A POLITICAL QUESTION
All in all, it would seem that the vast weight both of legislative practice and of executive opinion supports the proposition that the power of terminating outright international compacts to which the United States is party belongs, as a prerogative of sovereignty, to Congress alone, but that the President may, as an incident of his function of interpreting treaties preparatory to enforcing them, sometimes authoritatively find that a treaty contract with another power has or has not been breached by the latter and whether, for that reason, it is or is not longer binding on the United States.[191] At any rate, it is clear that any such questions which arise concerning a treaty are of a political nature and will not be decided by the courts. In the words of Justice Curtis in Taylor v. Morton:[192] It is not "a judicial question, whether a treaty with a foreign sovereign has been violated by him; whether the consideration of a particular stipulation in a treaty, has been voluntarily withdrawn by one party, so that it is no longer obligatory on the other; whether the views and acts of a foreign sovereign, manifested through his representative have given just occasion to the political departments of our government to withhold the execution of a promise contained in a treaty, or to act in direct contravention of such promise. * * * These powers have not been confided by the people to the judiciary, which has no suitable means to exercise them; but to the executive and the legislative departments of our government. They belong to diplomacy and legislation, and not to the administration of existing laws. And it necessarily follows, that if they are denied to Congress and the Executive, in the exercise of their legislative power, they can be found nowhere, in our system of government." Chief Justice Marshall's language in Foster v. Neilson[193] is to the same effect.
TREATIES AND THE NECESSARY AND PROPER CLAUSE
What power, or powers, does Congress exercise when it enacts legislation for the purpose of carrying treaties of the United States into effect? When the subject matter of the treaty falls within the ambit of Congress's enumerated powers (those listed in the first 17 clauses of article I, section 8 of the Constitution), then it is these powers which it exercises in carrying such treaty into effect. But if the treaty deals with a subject which falls normally to the States to legislate upon, or a subject which falls within the national jurisdiction because of its international character, then recourse is had to the necessary and proper clause. Thus, of itself, Congress would have no power to confer judicial powers upon foreign consuls in the United States, but the treaty-power can do this and has done it repeatedly and Congress has supplemented these treaties by appropriate legislation.[194] Again, Congress could not confer judicial power upon American consuls abroad to be there exercised over American citizens, but the treaty-power can and has, and Congress has passed legislation perfecting such agreements and such legislation has been upheld.[195] Again, Congress of itself could not provide for the extradition of fugitives from justice, but the treaty-power can and has done so scores of times, and Congress has passed legislation carrying our extradition treaties into effect.[196] Again, Congress could not ordinarily penalize private acts of violence within a State, but it can punish such acts if they deprive aliens of their rights under a treaty.[197] Referring to such legislation the Court has said: "The power of Congress to make all laws necessary and proper for carrying into execution as well the powers enumerated in section 8 of article I of the Constitution, as all others vested in the Government of the United States, or in any Department or the officers thereof, includes the power to enact such legislation as is appropriate to give efficacy to any stipulations which it is competent for the President by and with the advice and consent of the Senate to insert in a treaty with a foreign power."[198] In a word, the treaty-power cannot purport to amend the Constitution by adding to the list of Congress's enumerated powers, but having acted, the consequence will often be that it has provided Congress with an opportunity to enact measures which independently of a treaty Congress could not pass; and the only question that can be raised as to such measures will be whether they are "necessary and proper" measures for the carrying of the treaty in question into operation. The matter is further treated under the next heading.
CONSTITUTIONAL LIMITS OF THE TREATY-MAKING POWER; MISSOURI v. HOLLAND
Our system being theoretically opposed to the lodgement anywhere in government of unlimited power, the question of the scope of this exclusive power has often been pressed upon the Court, which has sometimes used language vaguely suggestive of limitation, as in the following passage from Justice Field's opinion for the Court in Geofroy v. Riggs,[199] which was decided in 1890: "The treaty power, as expressed in the Constitution, is in terms unlimited except by those restraints which are found in that instrument against the action of the government or of its departments, and those arising from the nature of the government itself and of that of the States. It would not be contended that it extends so far as to authorize what the Constitution forbids, or a change in the character of the government or in that of one of the States, or a cession of any portion of the territory of the latter, without its consent. * * * But with these exceptions, it is not perceived that there is any limit to the questions which can be adjusted touching any matter which is properly the subject of negotiation with a foreign country."[200] The fact is none the less, that no treaty of the United States nor any provision thereof has ever been found by the Court to be unconstitutional. The most persistently urged proposition in limitation of the treaty-making power has been that it must not invade certain reserved powers of the States. In view of the sweeping language of the supremacy clause, it is hardly surprising that this argument has not prevailed.[201] Nevertheless, the Court was forced to answer it as recently as 1923. This was in the case of Missouri v. Holland,[202] in which the Court sustained a treaty between the United States and Great Britain providing for the reciprocal protection of migratory birds which make seasonal flights from Canada into the United States and vice versa, and an act of Congress passed in pursuance thereof which authorized the Department of Agriculture to draw up regulations to govern the hunting of such birds, subject to the penalties specified by the act. To the objection that the treaty and implementing legislation invaded the acknowledged police power of the State in the protection of game within its borders, Justice Holmes, speaking for the Court, answered: "Acts of Congress are the supreme law of the land only when made in pursuance of the Constitution, while treaties are declared to be so when made under the authority of the United States. It is open to question whether the authority of the United States means more than the formal acts prescribed to make the convention. We do not mean to imply that there are no qualifications to the treaty-making power; but they must be ascertained in a different way. It is obvious that there may be matters of the sharpest exigency for the national well being that an act of Congress could not deal with but that a treaty followed by such an act could, and it is not lightly to be assumed that, in matters requiring national action, 'a power which must belong to and somewhere reside in every civilized government' is not to be found. (Andrews v. Andrews, 188 U.S. 14, 33 (1903)). What was said in that case with regard to the powers of the States applies with equal force to the powers of the nation in cases where the States individually are incompetent to act. * * * The treaty in question does not contravene any prohibitory words to be found in the Constitution. The only question is whether it is forbidden by some invisible radiation from the general terms of the Tenth Amendment. We must consider what this country has become in deciding what that Amendment has reserved."[203] And again: "Here a national interest of very nearly the first magnitude is involved. It can be protected only by national action in concert with that of another power. The subject-matter is only transitorily within the State and has no permanent habitat therein. But for the treaty and the statute there soon might be no birds for any powers to deal with. We see nothing in the Constitution that compels the Government to sit by while a food supply is cut off and the protectors of our forests and our crops are destroyed. It is not sufficient to rely upon the States. The reliance is vain, and were it otherwise, the question is whether the United States is forbidden to act. We are of opinion that the treaty and statute must be upheld."[204]
Justice Sutherland's later assertion in the Curtiss-Wright case[205] that the powers "to declare and wage war, to conclude peace, to make treaties," etc., belong to "the Federal Government as the necessary concomitants of nationality" leaves even less room for the notion of a limited treaty-making power, as indeed appears from his further statement that "as a member of the family of nations, the right and power of the United States * * * are equal to the right and power of the other members of the international family."[206] No doubt there are specific limitations in the Constitution in favor of private rights which "go to the roots" of all power. But these do not include the reserved powers of the States; nor do they appear to limit the National Government in its choice of matters concerning which it may treat with other governments.[207]
