John Paul Stevens,
United States v. R. Enterprises…
“ I stress, however, that the Court's opinion should not be read to suggest that the deferential relevance standard the Court has formulated will govern decision in every case, no matter how intrusive or burdensome the request. See ante, at 301 ("The Court of Appeals accordingly did not consider these aspects of the subpoenas, nor do we") .I agree with the Court that what is "unreasonable or oppressive" in the context of a trial subpoena is not necessarily unreasonable or oppressive in the grand jury context. ”
