G.L. Christian and Associates v. United States (312 F.2d 418 (Ct. Cl. 1963), cert. denied, 375 U.S. 954, 84 S.Ct. 444) is a 1963 United States Federal Acquisition Regulation (FAR) court case which has become known as the Christian Doctrine. The case held that standard clauses established by regulations may be considered as being in every Federal contract. Because the FAR is the law, and government contractors are presumed to be familiar with the FAR, a mandatory clause that expresses a significant or deeply ingrained strand of public procurement policy will be incorporated into a Government contract by operation of law, even if the parties intentionally omitted it.
