Portrait of Hugo Black 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.

The scrupulous observance, with some deviations, of the professed limits of this Court's power to strike down legislation has been, perhaps, the one quality the great judges of the Court have had in common. Particularly when congressional legislation is under scrutiny, every rational trail must be pursued to prevent collision between Congress and Court. For Congress can readily mend its ways, or the people may express disapproval by choosing different representatives.

The fact that the punishment is inflicted through the instrumentality of an Act specifically cutting off the pay of certain named individuals found guilty of disloyalty, makes it no less galling or effective than if it had been done by an Act which designated the conduct as criminal. [5] No one would think that Congress could have passed a valid law, stating that after investigation it had found Lovett, Dodd, and Watson 'guilty' of the crime of engaging in 'subversive activities,' defined that term for the first time, and sentenced them to perpetual exclusion from any government employment.
