Henry Billings Brown,
Hale v. Henkel — Opinion of the Court
“ While there may be some doubt whether the examination of witnesses before a grand jury is a suit or prosecution, we have no doubt that it is a 'proceeding' within the meaning of this proviso. The word should receive as wide a construction as is necessary to protect the witness in his disclosures, whenever such disclosures are made in pursuance of a judicial inquiry, whether such inquiry be instituted by a grand jury, or upon the trial of an indictment found by them. The word 'proceeding' is not a technical one, and is aptly used by the courts to designate an inquiry before a grant jury. ”
