Abe Fortas,
Gojack v. United States — Opinion of the Court
“ We do not question the authority of the Committee appropriately to delegate functions to a subcommittee of its members, nor do we doubt the availability of § 192 for punishment of contempt before such a subcommittee in proper cases. But here, not only did the Committee fail to authorize its own investigation, but also it failed to specify the subject of inquiry that the Subcommittee was to undertake. The criminal law cannot be used to implement jurisdiction so obtained, without metes and bounds, without statement or description of the subject committed to the Subcommittee. ”
