United States constitutional sentencing law

The United States Constitution contains several provisions related to criminal sentencing.

The Excessive Fines Clause and the Cruel and Unusual Punishments Clause of the Eighth Amendment to the United States Constitution prohibit certain disproportionate sentences. Further, the Cruel and Unusual Punishments Clause prohibits the imposition of the death penalty for certain crimes, for certain classes of defendants, and in the absence of certain procedures. The Sixth Amendment to the United States Constitution prohibits increasing the maximum authorized sentence for an offense based on a fact not found by a jury. Mandatory minimums based on judicial fact-finding are not prohibited. The Double Jeopardy Clause of the Fifth Amendment to the United States Constitution prohibits multiple punishments for the same offense. The test of Blockburger v. United States (1932) is whether each crime contains an element that the other does not.
