Hugo Black,
United States v. Lovett — Opinion of the Court
(1946)
“ Congress need merely omit its ground of condemnation and legislate the penalty! But the prohibition against a 'Bill of Attainder' is only one of the safeguards of liberty in the arsenal of the Constitution. There are other provisions in the Constitution, specific and comprehensive, effectively designed to assure the liberties of our citizens. The restrictive function of this clause against bills of attainder was to take from the legislature a judicial function which the legislature once possessed. ”
