Felix Frankfurter,
Piemonte v. United States — Opinion of the Court
“ Petitioner plainly must have known-and gave every indication that he knew-that he was required to answer all questions put to him by the grand jury in return for equivalent, compensating immunity. We find no merit in an argument which is contradicted by petitioner's own assertion, supported by his counsel's argument, that he refused to testify solely because of fear. ”
