United States v. Curtiss-Wright Export Corp.

Mr. Justice SUTHERLAND delivered the opinion of the Court.

On January 27, 1936, an indictment was returned in the court below, the first count of which charges that appellees, beginning with the 29th day of May, 1934, conspired to sell in the United States certain arms of war, namely, fifteen machine guns, to Bolivia, a country then engaged in armed conflict in the Chaco, in violation of the Joint Resolution of Congress approved May 28, 1934, and the provisions of a proclamation issued on the same day by the President of the United States pursuant to authority conferred by section 1 of the resolution. In pursuance of the conspiracy, the commission of certain overt acts was alleged, details of which need not be stated.

Whether, if the Joint Resolution had related solely to internal affairs, it would be open to the challenge that it constituted an unlawful delegation of legislative power to the Executive, we find it unnecessary to determine. The whole aim of the resolution is to affect a situation entirely external to the United States, and falling within the category of foreign affairs. The determination which we are called to make, therefore, is whether the Joint Resolution, as applied to that situation, is vulnerable to attack under the rule that forbids a delegation of the lawmaking power. In other words, assuming (but not deciding) that the challenged delegation, if it were confined to internal affairs, would be invalid, may it nevertheless be sustained on the ground that its exclusive aim is to afford a remedy for a hurtful condition within foreign territory?

It will contribute to the elucidation of the question if we first consider the differences between the powers of the federal government in respect of foreign or external affairs and those in respect of domestic or internal affairs. That there are differences between them, and that these differences are fundamental, may not be doubted.

The two classes of powers are different, both in respect of their origin and their nature. The broad statement that the federal government can exercise no powers except those specifically enumerated in the Constitution, and such implied powers as are necessary and proper to carry into effect the enumerated powers, is categorically true only in respect of our internal affairs. In that field, the primary purpose of the Constitution was to carve from the general mass of legislative powers then possessed by the states such portions as it was thought desirable to vest in the federal government, leaving those not included in the enumeration still in the states. That this doctrine applies only to powers which the states had is self-evident. And since the states severally never possessed international powers, such powers could not have been carved from the mass of state powers but obviously were transmitted to the United States from some other source. During the Colonial period, those powers were possessed exclusively by and were entirely under the control of the Crown. By the Declaration of Independence, 'the Representatives of the United States of America' declared the United (not the several) Colonies to be free and independent states, and as such to have 'full Power to levy War, conclude Peace, contract Alliances, establish Commerce and to do all other Acts and Things which Independent States may of right do.'

As a result of the separation from Great Britain by the colonies, acting as a unit, the powers of external sovereignty passed from the Crown not to the colonies severally, but to the colonies in their collective and corporate capacity as the United States of America. Even before the Declaration, the colonies were a unit in foreign affairs, acting through a common agency-namely, the Continental Congress, composed of delegates from the thirteen colonies. That agency exercised the powers of war and peace, raised an army, created a navy, and finally adopted the Declaration of Independence. Rulers come and go; governments end and forms of government change; but sovereignty survives. A political society cannot endure without a supreme will somewhere.

It results that the investment of the federal government with the powers of external sovereignty did not depend upon the affirmative grants of the Constitution. The powers to declare and wage war, to conclude peace, to make treaties, to maintain diplomatic relations with other sovereignties, if they had never been mentioned in the Constitution, would have vested in the federal government as necessary concomitants of nationality.

Not only, as we have shown, is the federal power over external affairs in origin and essential character different from that over internal affairs, but participation in the exercise of the power is significantly limited. 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.'

It is important to bear in mind that we are here dealing not alone with an authority vested in the President by an exertion of legislative power, but with such an authority plus the very delicate, plenary and exclusive power of the President as the sole organ of the federal government in the field of international relations-a power which does not require as a basis for its exercise an act of Congress, but which, of course, like every other governmental power, must be exercised in subordination to the applicable provisions of the Constitution. It is quite apparent that if, in the maintenance of our international relations, embarrassment-perhaps serious embarrassment-is to be avoided and success for our aims achieved, congressional legislation which is to be made effective through negotiation and inquiry within the international field must often accord to the President a degree of discretion and freedom from statutory restriction which would not be admissible were domestic affairs alone involved. Moreover, he, not Congress, has the better opportunity of knowing the conditions which prevail in foreign countries, and especially is this true in time of war. He has his confidential sources of information. He has his agents in the form of diplomatic, consular and other officials. Secrecy in respect of information gathered by them may be highly necessary, and the premature disclosure of it productive of harmful results.

In the light of the foregoing observations, it is evident that this court should not be in haste to apply a general rule which will have the effect of condemning legislation like that under review as constituting an unlawful delegation of legislative power. The principles which justify such legislation find overwhelming support in the unbroken legislative practice which has prevailed almost from the inception of the national government to the present day.
