Charles Evans Whittaker,
McPhaul v. United States — Opinion of the Court
“ We allow a man to go to prison for doing no more, so far as this record reveals, than challenging the right of a Committee to ask him to produce documents. The Congress had the right to get these documents from someone. But, when it comes to criminal prosecutions, the Government must turn square corners. If Congress desires to have the judiciary adjudge a man guilty for failure to produce documents, the prosecution should be required to prove that the man whom we send to prison had the power to produce them. ”
