Behind any Federal Government acquisition is legislation that permits it and provided money for it. These are normally covered in authorization and appropriation legislation. Generally, this legislation does not affect the acquisition process itself, although the appropriation process has been used to amend procurement laws, notably with the Federal Acquisition Reform Act (FARA) and the Federal Acquisitions Streamlining Act (FASA). Other relevant laws include the Federal Property and Administrative Services Act of 1949, the Armed Services Procurement Act (ASPA) and the Antideficiency Act.
