No. 471
Argued December 16, 1914
Decided January 25, 1915
236 U.S. 79
Syllabus
Acceptance, as well as delivery, of a pardon is essential to its validity; if rejected by the person to whom it is tendered, the court has no power to force it on him.
United States v. Wilson, 7 Pet. 150.
There are substantial differences between legislative immunity and a pardon;
the latter carries an imputation of guilt and acceptance of a confession of it, while the former is noncommittal, and tantamount to silence of the witness.
There is a distinction between amnesty and pardon; the former overlooks the offense, and is usually addressed to crimes against the sovereignty of the state and political offenses,
the latter remits punishment and condones infractions of the peace of the state.
