by John Marshall Harlan, Hepner v. United States — Opinion of the Court
“ If, in a civil action to recover a penalty, the defendant is entitled, the evidence being undisputed, to have a peremptory instruction in his behalf, it is difficult to perceive why the government is not entitled to a peremptory instruction in its favor, where the undisputed testimony left no facts for the jury to consider, but established, beyond all question and as matter of law, its right to judgment for the prescribed penalty. ”
