Congress sometimes requires great specificity in administrative reporting. Exemplifying such demands are the following statutes. A 1950 statute limited the number of Army officers who might be assigned to permanent duty in the Department of the Army and the number who could be assigned to the Army General Staff at any one time. The Secretary of the Army is required to report quarterly to the Congress the number of officers and the justification therefor.[597] This is a simple but extremely precise reporting requirement. The May, 1937 amendment to the Neutrality Act more generally defined and described the various topics to be covered in the annual report of the National Munitions Control Board, but stipulated that the report contain a list of all persons required to register under the provisions of the Act, and full information concerning the licenses which had been issued thereunder.[598] A like blend of liberality and rigidity in stipulating the content of reports was manifested in a 1937 Act designed to establish a government monopoly of the production of helium gas.[599] The National Munitions Control Board was to include in its Annual Report to the Congress full information concerning the export licenses issued thereunder and whatever additional information and data the Board considered of value in the determination of questions related to the exportation of helium gas.[600] The Secretary of the Navy was directed in 1938 to report annually to the Congress all agreements entered into for leasing naval petroleum reserves;[601] and a 1939 statute to facilitate certain construction work for the Army required the Secretary of War to report annually to the Congress all contracts entered into under authority of the Act, including the names of the contractors and copies of the contracts concerned, together with the amounts involved.[602] The Sixth Supplemental National Defense Appropriation Act of 1942 established the duty of the Secretary of War and Secretary of the Navy to submit a complete list of all contracts awarded in excess of $150,000 together with the names of the contractors, and the subject matter of each contract. If the contract had been awarded without competitive bidding, the Secretaries had to supply Congress with a statement of the principal or controlling reason for selection of the contractors. Reports had to be submitted within sixty days after the end of the fiscal year.[603] In the main the congressional requirement of reporting is cast in general terms, permitting the administrator considerable discretion as to content and precise date (if not periodicity) of submission. On occasion, however, Congress is disposed to insist upon specificity in exacting reports from agencies, particularly agencies assigned such tasks as the registering of individuals, licensing, letting contracts, and the like.
