Constitutional bans
The United States Constitution forbids legislative bills of attainder under Article I, Section 9. It was considered an excess or abuse by the British monarchy and Parliament. No bills of attainder have been passed since 1798 in the UK.[citation needed] Attainder as such was also a legal consequence of convictions in courts of law, but this ceased to be a part of punishment in 1870.[11] The provision forbidding state law bills of attainder, Article I, Section 10, reflects the importance that the framers attached to this issue.
Within the U.S. Constitution, the clauses forbidding attainder laws serve two purposes. First, they reinforced the separation of powers, by forbidding the legislature to perform judicial or executive functions—since the outcome of any such acts of legislature would of necessity take the form of a bill of attainder. Second, they embody the concept of due process, which was partially reinforced by the Fifth Amendment to the Constitution. The text of the Constitution, Article I, Section 9; Clause 3 is "No Bill of Attainder or ex post facto Law shall be passed". The constitution of every State also expressly forbids bills of attainder. For example, Wisconsin's constitution Article I, Section 12 reads:
No bill of attainder, ex post facto law, nor any law impairing the obligation of contracts, shall ever be passed, and no conviction shall work corruption of blood or forfeiture of estate.
Contrast this with the subtly more modern variation of the Texas version: Article 1 (Titled Bill of Rights) Section 16, entitled Bills of Attainder; Ex Post Facto or Retroactive Laws: Impairing Obligation of Contracts: "No bill of attainder, ex post facto law, retroactive law, or any law impairing the obligation of contracts, shall be made".
