"Sequestration is a process of automatic, largely across-the-board spending reductions under which budgetary resources are permanently canceled to enforce certain budget policy goals. It was first authorized by the Balanced Budget and Emergency Deficit Control Act of 1985 (BBEDCA, Title II of P.L. 99-177, commonly known as the Gramm-Rudman-Hollings Act). Sequestration is of current interest because it has been triggered as an enforcement tool under the Budget Control Act of 2011 (BCA, P.L. 112-25). Sequestration can also occur under the Statutory Pay-As-You-Go Act of 2010 (Statutory PAYGO, Title I of P.L. 111-139). In either case, certain programs are exempt from sequestration, and special rules govern the effects of sequestration on others. Most of these provisions are found in Sections 255 and 256 of BBEDCA, as amended."--Summary.
