§ 4.101 Official rulings and interpretations in this subpart.

(a) The purpose of this subpart is to provide, pursuant to the authority cited in § 4.102, official rulings and interpretations with respect to the application of the McNamara-O'Hara Service Contract Act for the guidance of the agencies of the United States and the District of Columbia which may enter into and administer contracts subject to its provisions, the persons desiring to enter into such contracts with these agencies, and the contractors, subcontractors, and employees who perform work under such contracts.

(b) These rulings and interpretations are intended to indicate the construction of the law and regulations which the Department of Labor believes to be correct and which will be followed in the administration of the Act unless and until directed otherwise by Act of Congress or by authoritative ruling of the courts, or if it is concluded upon reexamination of an interpretation that it is incorrect. See for example, Skidmore v. Swift & Co., 323 U.S. 134 (1944); Roland Co. v. Walling, 326 U.S. 657 (1946); Endicott Johnson Corp. v. Perkins, 317 U.S. 501, 507-509 (1943); Perkins v. Lukens Steel Co., 310 U.S. 113, 128 (1940); United States v. Western Pacific Railroad Co., 352 U.S. 59 (1956). The Department of Labor (and not the contracting agencies) has the primary and final authority and responsibility for administering and interpreting the Act, including making determinations of coverage. See Woodside Village v. Secretary of Labor, 611 F. 2d 312 (9th Cir. 1980); Nello L. Teer Co. v. United States, 348 F.2d 533, 539-540 (Ct. Cl. 1965), cert. denied, 383 U.S. 934; North Georgia Building & Construction Trades Council v. U.S. Department of Transportation, 399 F. Supp. 58, 63 (N.D. Ga. 1975) (Davis-Bacon Act); Curtiss-Wright Corp. v. McLucas, 364 F. Supp. 750, 769-72 (D.N.J. 1973); and 43 Atty. Gen. Ops. __ (March 9, 1979); 53 Comp. Gen. 647, 649-51 (1974); 57 Comp. Gen. 501, 506 (1978).
