Congress cannot limit the effects of a Presidential amnesty. Thus the act of July 12, 1870, making proof of loyalty necessary to recover property abandoned and sold by the government during the Civil War, notwithstanding any Executive proclamation, pardon, amnesty, or other act of condonation or oblivion, was pronounced void. Said Chief Justice Chase for the majority: "* * * the legislature cannot change the effect of such a pardon any more than the executive can change a law. Yet this is attempted by the provision under consideration. The Court is required to receive special pardons as evidence of guilt and to treat them as null and void. It is required to disregard pardons granted by proclamation on condition, though the condition has been fulfilled, and to deny them their legal effect. This certainly impairs the executive authority and directs the Court to be instrumental to that end."[140] On the other hand, Congress may itself, under the necessary and proper clause, enact amnesty laws remitting penalties incurred under the national statutes,[141] and may stipulate that witnesses before courts or other bodies qualified to take testimony shall not be prosecuted by the National Government for any offenses disclosed by their testimony.[142]
Clause 2. He shall have Power, by and with the Advice and Consent of the Senate, to make Treaties, provided two thirds of the Senators present concur; and he shall nominate, and by and with the Advice and Consent of the Senate, shall appoint Ambassadors, other public Ministers and Consuls, Judges of the supreme Court, and all other Officers of the United States, whose Appointments are not herein otherwise provided for, and which shall be established by Law: but the Congress may by Law vest the Appointment of such inferior Officers, as they think proper, in the President alone, in the Courts of Law, or in the Heads of Departments.
The Treaty-Making Power
PRESIDENT AND SENATE
The plan which the Committee of Detail reported to the Federal Convention on August 6, 1787 provided that "the Senate of the United States shall have power to make treaties, and to appoint Ambassadors, and Judges of the Supreme Court."[143] Not until September 7, ten days before the Convention's final adjournment, was the President made a participant in these powers.[144] The constitutional clause evidently assumes that the President and Senate will be associated throughout the entire process of making a treaty, although Jay, writing in The Federalist, foresaw that the initiative must often be seized by the President without benefit of Senatorial counsel.[145] Yet so late as 1818 Rufus King, Senator from New York, who had been a member of the Convention, declared on the floor of the Senate: "In these concerns the Senate are the Constitutional and the only responsible counsellors of the President. And in this capacity the Senate may, and ought to, look into and watch over every branch of the foreign affairs of the nation; they may, therefore, at any time call for full and exact information respecting the foreign affairs, and express their opinion and advice to the President respecting the same, when, and under whatever other circumstances, they may think such advice expedient."[146]
NEGOTIATION A PRESIDENTIAL MONOPOLY
Actually, the negotiation of treaties had long since been taken over by the President; the Senate's role in relation to treaties is today essentially legislative in character.[147] "He alone negotiates. Into the field of negotiation, the Senate cannot intrude; and Congress itself is powerless to invade it," declared Justice Sutherland for the Court in 1936.[148] The Senate must, moreover, content itself with such information as the President chooses to furnish it.[149] In performing the function that remains to it, however, it has several options. It may consent unconditionally to a proposed treaty, or it may refuse its consent, or it may stipulate conditions in the form of amendments to the treaty or of reservations to the act of ratification, the difference between the two being that, whereas amendments, if accepted by the President and the other party or parties to the Treaty,[150] change it for all parties, reservations limit only the obligations of the United States thereunder. The act of ratification for the United States is the President's act, but may not be forthcoming unless the Senate has consented to it by the required two-thirds of the Senators present, which signifies two-thirds of a quorum, otherwise the consent rendered would not be that of the Senate as organized under the Constitution to do business.[151] Conversely, the President may, if dissatisfied with amendments which have been affixed by the Senate to a proposed treaty or with the conditions stipulated by it to ratification, decide to abandon the negotiation, which he is entirely free to do.[152]
TREATIES AS LAW OF THE LAND
Treaty commitments of the United States are of two kinds. In the language of Chief Justice Marshall in 1829; "A treaty is, in its nature, a contract between two nations, not a legislative act. It does not generally effect, of itself, the object to be accomplished; especially, so far as its operation is infraterritorial; but is carried into execution by the sovereign power of the respective parties to the instrument. In the United States, a different principle is established. Our constitution declares a treaty to be the law of the land. It is, consequently, to be regarded in courts of justice as equivalent to an act of the legislature, whenever it operates of itself, without the aid of any legislative provision. But when the terms of the stipulation import a contract—when either of the parties engages to perform a particular act, the treaty addresses itself to the political, not the judicial department; and the legislature must execute the contract, before it can become a rule for the Court."[153] To the same effect, but more accurate, is Justice Miller's language for the Court a half century later, in Head Money Cases: "A treaty is primarily a compact between independent nations. It depends for the enforcement of its provisions on the interest and the honor of the governments which are parties to it. * * * But a treaty may also contain provisions which confer certain rights upon the citizens or subjects of one of the nations residing in the territorial limits of the other, which partake of the nature of municipal law, and which are capable of enforcement as between private parties in the courts of the country."[154]
