The procurement process for executive branch agencies (as distinguished from legislative or judicial bodies) is governed primarily by the Armed Services Procurement Act and the Federal Property and Administrative Services Act. To address the many rules imposed by Congress and the courts, a body of administrative law has been developed through the Federal Acquisition Regulation. This 53 - part regulation defines the procurement process including special preference programs, and includes the specific language of many clauses in Government contracts. Most agencies also have supplemental regulatory coverage contained in what are known as FAR Supplements. These supplements appear within the Code of Federal Regulations (CFR) volumes of the respective agencies. For example, the Department of Defense (DOD) FAR Supplement can be found at 10 CFR.
