While the validity of several of the measures just reviewed was assailed on one constitutional ground or another, the general power of Congress to regulate their subject matter in time of war was not disputed. Not until the Government sought to recover excessive profits realized on war contracts did the Supreme Court have occasion to affirm the broad authority of the National Government to mobilize the industrial resources of the nation in time of war. Using the power of Congress to conscript men for the armed forces as a measure of its power to regulate industry, the Court sustained the legislation, saying: "The Renegotiation Act was developed as a major wartime policy of Congress comparable to that of the Selective Service Act. The authority of Congress to authorize each of them sprang from its war powers. * * * With the advent of * * * [global] warfare, mobilized property in the form of equipment and supplies became as essential as mobilized manpower. Mobilization of effort extended not only to the uniformed armed services but to the entire population. Both Acts were a form of mobilization. The language of the Constitution authorizing such measures is broad rather than restrictive. * * * [It] * * * places emphasis upon the supporting as well as upon the raising of armies. The power of Congress as to both is inescapably express, not merely implied."[1268]
DELEGATION OF LEGISLATIVE POWER IN WARTIME
While insisting that, "in peace or in war it is essential that the Constitution be scrupulously obeyed, and particularly that the respective branches of the Government keep within the powers assigned to each,"[1269] the Supreme Court has recognized that in the conduct of a war delegations of power may be valid which would not be admissible in other circumstances. The cases in which this issue has been raised have been few in number. In one, the Selective Draft Law cases,[1270] the objection was dismissed without discussion. In a second, the price-fixing authority exercised by the Office of Price Administration during the second world war, was, on the issue of delegation of power, sustained by reference to peace time precedents.[1271] Where the war power has been the basis of decision, two different theories concerning its significance can be recognized. The first is that since the war power is an inherent power shared by the legislative and executive departments rather than an enumerated power granted to the former, Congress does not delegate legislative power when it authorizes the President to exercise the war power in a prescribed manner. Opposed to this is the view that the right of Congress to delegate power to the President is limited in this as in other cases but that where the validity of the delegation depends upon whether or not too great a latitude of discretion has been conferred upon the Executive, the existence of a state of war is a factor to be considered in determining whether the delegation in the particular case is necessary and hence permissible.
The idea that a delegation of discretion in the exercise of the war power stands on a different footing than delegation of authority to levy a tax is implicit in Justice Bradley's opinion in Hamilton v. Dillin.[1272] The plaintiffs in that case contended that the sum they were required to pay for the privileges of buying cotton in the South was a tax, which, since it was imposed by the Secretary of the Treasury, was invalid because the taxing power was not susceptible of delegation to the Executive Department. To this argument the Court replied: "It is hardly necessary, under the view we have taken of the character of the regulations in question, * * *, to discuss the question of the constitutionality of the act of July 13th, 1861, regarded as authorizing such regulations. * * *, the power of the Government to impose such conditions upon commercial intercourse with an enemy in time of war * * * does not belong to the same category as the power to levy and collect taxes, duties, and excises. It belongs to the war powers of the Government * * *."[1273]
The Mergence of Legislative and Executive in Wartime
Both theories receive countenance in different passages in the opinion of Chief Justice Stone in Hirabayashi v. United States.[1274] In disposing of the contention that the curfew imposed upon a citizen of Japanese descent involved an invalid delegation of legislative power, the Chief Justice said: "The question then is not one of Congressional power to delegate to the President the promulgation of the Executive Order, but whether, acting in cooperation, Congress and the Executive have constitutional authority to impose the curfew restriction here complained of. * * *, we conclude that it was within the constitutional power of Congress and the executive arm of the Government to prescribe this curfew order for the period under consideration and that its promulgation by the military commander involved no unlawful delegation of legislative power. * * * Where, as in the present case, the standard set up for the guidance of the military commander, and the action taken and the reasons for it, are in fact recorded in the military orders, so that Congress, the courts and the public are assured that the orders, in the judgment of the commander, conform to the standards approved by the President and Congress, there is no failure in the performance of the legislative function."[1275] He went on to say, however, that: "The essentials of [the legislative] * * * function are the determination by Congress of the legislative policy and its approval of a rule of conduct to carry that policy into execution. The very necessities which attend the conduct of military operations in time of war in this instance as in many others preclude Congress from holding committee meetings to determine whether there is danger, before it enacts legislation to combat the danger."[1276]
Doctrine of Lichter v. United States
A similar ambiguity is found in Lichter v. United States,[1277] but on the whole the opinion seems to espouse the second theory, as the following excerpts indicate: "A constitutional power implies a power of delegation of authority under it sufficient to effect its purposes.—This power is especially significant in connection with constitutional war powers under which the exercise of broad discretion as to methods to be employed may be essential to an effective use of its war powers by Congress. The degree to which Congress must specify its policies and standards in order that the administrative authority granted may not be an unconstitutional delegation of its own legislative power is not capable of precise definition.[1278] * * * Thus, while the constitutional structure and controls of our Government are our guides equally in war and in peace, they must be read with the realistic purposes of the entire instrument fully in mind. In 1942, in the early stages of total global warfare, the exercise of a war power such as the power 'To raise and support Armies, * * *' and 'To provide and maintain a Navy; * * *,' called for the production by us of war goods in unprecedented volume with the utmost speed, combined with flexibility of control over the product and with a high degree of initiative on the part of the producers. Faced with the need to exercise that power, the question was whether it was beyond the constitutional power of Congress to delegate to the high officials named therein the discretion contained in the Original Renegotiation Act of April 28, 1942, and the amendments of October 21, 1942. We believe that the administrative authority there granted was well within the constitutional war powers then being put to their predestined uses."[1279]
WAR POWERS IN TIME OF PEACE
To some indeterminate extent the power to wage war embraces the power to prepare for it and the further power to deal with the problem of adjustment after hostilities have ceased. In his Commentaries, Justice Story wrote as follows with specific reference to the question of preparation for war: "'It is important also to consider, that the surest means of avoiding war is to be prepared for it in peace. * * * How could a readiness for war in time of peace be safely prohibited, unless we could in like manner prohibit the preparations and establishments of every hostile nation? The means of security can be only regulated by the means and the danger of attack. * * * It will be in vain to oppose constitutional barriers to the impulse of self-preservation.'"[1280] Authoritative judicial recognition of the power is found in Ashwander v. Tennessee Valley Authority,[1281] where, in sustaining the power of the Government to construct and operate Wilson Dam and the power plant connected with it, pursuant to the National Defense Act of June 3, 1916,[1282] the Court said: "While the District Court found that there is no intention to use the nitrate plants or the hydroelectric units installed at Wilson Dam for the production of war materials in time of peace, 'the maintenance of said properties in operating condition and the assurance of an abundant supply of electric energy in the event of war, constitute national defense assets.' This finding has ample support."[1283]
