(a) In order to clarify at this time the practices and policies which will guide the administration and enforcement of the Fair Labor Standards Act of 1938, as amended (52 Stat. 1060, 29 U.S.C. 201-219), and the Walsh-Healey Act as amended (49 Stat. 2036, 41 U.S.C. 35-45), as affected by the Portal-to-Portal Act of 1947 (61 Stat. 84; 29 U.S.C. Sup. 251 et seq.), the following policy is announced effective June 30, 1947.

(b) The investigation, inspection and enforcement activities of all officers and agencies of the Department of Labor as they relate to the Fair Labor Standards Act and the Walsh-Healey Act will be carried out on the basis that all employers in all industries whose activities are subject to the provisions of the Fair Labor Standards Act or the Walsh-Healey Act are responsible for strict compliance with the provisions thereof and the regulations issued pursuant thereto.

(c) Any statements, orders, or instructions inconsistent herewith are rescinded.

Advisory interpretations announced by the Administrator serve only to indicate the construction of the law which will guide the Administrator in the performance of his administrative duties unless he is directed otherwise by the authoritative ruling of the courts, or unless he shall subsequently decide that his prior interpretation is incorrect.
