The First Decontrol Act of 1947, providing for the termination of certain of the provisions of the Second War Powers Act, permitted the continued exercise of power to allocate materials which were certified by the Secretaries of State and Commerce as necessary to meet international commitments.[348] Section 101 of the Defense Production Act of 1950 empowered the President to allocate materials in such manner, upon such conditions, and to such extent as he deems necessary or appropriate to promote the national defense.[349] A related section provided that no person should accumulate (1) in excess of the reasonable demands of business, personal, or home consumption, or (2) for the purpose of resale at prices in excess of prevailing market prices, materials which had been designated by the President as scarce materials or materials the supply of which would be threatened by such accumulation.[350] The Atomic Energy Act of 1946, as amended in 1951, expands the allocation power to its logical extreme by allocating all fissionable material to the federal government, making it unlawful for any person to possess or transfer any fissionable material, except as authorized by the Atomic Energy Commission.[351] CONTROL OF PRODUCTIVE FACILITIES _Priorities_: Particularly in the conversion period preceding full-scale defense production it is necessary to compel producers to accord first priority to fulfillment of government contracts. During such interval prior to all-out defense mobilization, when his competitors may be satisfying the demands of consumers, the businessman has ample cause to fear that in giving priority to government orders disgruntled private customers will be permanently lost to competing firms. Accordingly, a June 1940 statute provided that, in the discretion of the President, fulfillment of Army or Navy contracts was to take priority over all deliveries for private account or for export.[352] In a year this was amended to extend the President’s power over priorities to include contracts or orders for the Government of any country whose defense the President deemed vital to the defense of the United States and contracts or orders, or subcontracts or sub-orders, which the President deemed necessary or appropriate to promote the defense of the United States.[353] In May 1941 the Maritime Commission was empowered to demand that work on its contracts take priority over the furnishing of materials or performance of work for private account or for export.[354] The Second War Powers Act continued in effect the provision of the June 1940 and May 1941 statutes[355] by providing that all orders for vessels, equipment, and weapons placed by the Army and Navy were, in the discretion of the President, to take priority over all deliveries for private account or for export.
