Bill of attainder

Legislation declaring a person guilty

A bill of attainder is an act of a legislature declaring a person, or a group of people, guilty of some crime, and providing for a punishment, often without a trial. As with attainder resulting from the normal judicial process, the effect of such a bill is to nullify the targeted person's civil rights, most notably the right to own property, the right to a title of nobility, and, in at least the original usage, the right to life itself.
