George Sutherland, United States v. Benz — Opinion of the Court
“ We find nothing in the suggestion that the action of the district court in reducing the punishment after the prisoner had served a part of the imprisonment originally imposed was a usurpation of the pardoning power of the executive. The judicial power and the executive power over sentences are readily distinguishable. To render judgment is a judicial function. To carry the judgment into effect is an executive function. To cut short a sentence by an act of clemency is an exercise of executive power which abridges the enforcement of the judgment, but does not alter it qua judgment. ”
