A bill of attainder is a legislative act declaring a person or group of persons guilty of a crime and punishing them without benefit of a trial. During the eighteenth century, England applied bills of attainder to its colonies in America. Declaration of guilt usually meant, among other consequences, that the guilty party forfeited all of their property to the Crown. The U.S. Constitution forbids both the federal and state governments to enact bills of attainder.

The Fifth Amendment to the U.S. Constitution provides: “In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury. . . .” How does this amendment relate to the prohibition of bills of attainder as provided in the Constitution?
