William J. Brennan, Jr., Picard v. Connor — Opinion of the Court
“ Hence, we do not imply that respondent could have raised the equal protection claim only by citing 'book and verse on the federal constitution.' Daugharty v. Gladden, 257 F.2d 750, 758 (CA9 1958) ; see Kirby v. Warden, 296 F.2d 151 (CA4 1961) . We simply hold that the substance of a federal habeas corpus claim must first be presented to the state courts. The claim that an indictment is invalid is not the substantial equivalent of a claim that it results in an unconstitutional discrimination. ”
