Hugo Black,
United States Marcus v. Hess — Opinion of the Court
“ The short of it is that where two such proceedings merely carry out the remedies which Congress has prescribed in advance for a wrong, they do not twice put a man in jeopardy for the same offense. Congress thereby merely allows the comprehensive penalties which it has imposed to be enforced in separate suits instead of in a single proceeding. By doing this Congress does not impose more than a single punishment. And the double jeopardy clause does not prevent Congress from prescribing such a procedure for the vindication of punitive remedies. ”
