William Rehnquist,
Murray v. Giarratano — Opinion of the Court
“ State collateral proceedings are not constitutionally required as an adjunct to the state criminal proceeding and serve a different and more limited purpose than either the trial or appeal. Eighth Amendment safeguards imposed at the trial stage-where the court and jury hear testimony, receive evidence, and decide the question of guilt and punishment-are sufficient to assure the reliability of the process by which the death penalty is imposed. ”
