Alabama v. Pugh
In Alabama v. Pugh, 438 U.S. 781, 98 S.Ct. 3057, 57 L.Ed.2d 1114 (1978) (per curiam), prison inmates in an action filed pursuant to 42 U.S.C. 1983 succeeded in obtaining an injunction against the state of Alabama, the Alabama Board of Corrections, and several prison officials prescribing measures to eradicate cruel and unusual punishment in the Alabama prison system.
Although the injunction was concededly proper as to all of the other parties, the Supreme Court held its issuance against the state and Board of Corrections was barred by the Eleventh Amendment unless Alabama consented to the filing of the suit.
