In Carafas v. La Vallee (1968) 391 U.S. 234, the United States Supreme Court was dealing with a question of mootness with respect to a state prisoner who had been discharged from custody while his federal habeas corpus proceedings was pending. Noting that federal jurisdiction had attached upon the filing of the petition while the prisoner was in custody, the United States Supreme Court rejected a suggestion of mootness, remarking that the challenged state judgment created disabilities in regard to employment, voting and jury service.
