The United States Sentencing Commission is an independent agency of the judicial branch of the U.S. federal government. It is responsible for articulating the U.S. Federal Sentencing Guidelines for the federal courts. The Commission promulgates the Federal Sentencing Guidelines, which replaced the prior system of indeterminate sentencing that allowed trial judges to give sentences ranging from probation to the maximum statutory punishment for the offense. It is headquartered in Washington, D.C.
The commission was created by the Sentencing Reform Act provisions of the Comprehensive Crime Control Act of 1984. The constitutionality of the commission was challenged as a congressional encroachment on the power of the executive but upheld by the Supreme Court in Mistretta v. United States, 488 U.S. 361 (1989).
