Headnotes

  1. Criminal Law & Procedure — Exclusionary Rule The essence of a constitutional provision forbidding the acquisition of evidence in a certain way is that not merely evidence so acquired shall not be used before the court, but that it shall not be used at all; the Government may not use knowledge of the existence and contents of documents, obtained through an unconstitutional search and seizure, to call upon their owners by subpoena to produce them. 251 U.S. at 392
  2. Criminal Law & Procedure — Fourth Amendment Facts obtained through an unconstitutional search and seizure do not become sacred and inaccessible; if knowledge of them is gained from an independent source, they may be proved like any others, but knowledge gained by the Government's own wrong cannot be used by it. 251 U.S. at 392
  3. Criminal Law & Procedure — Fourth Amendment Decisions holding that a collateral inquiry into the mode by which evidence has been obtained will not be allowed when the question is first raised at the trial furnish no authority in a proceeding where the objection under the Fourth Amendment is seasonably interposed, as by a prompt application for the return of the seized papers. 251 U.S. at 392
  4. Constitutional Law — Fourth Amendment The rights of a corporation against unlawful search and seizure are to be protected even if the same result might have been achieved in a lawful way, notwithstanding that a corporation is not privileged under the Fifth Amendment from producing its books and papers. 251 U.S. at 392
