Harlan F. Stone,
Hudson v. United States — Opinion of the Court
“ The text states the rule of law that has never been questioned that the implied confession, as contrasted to the express confession, does not estop the defendant to plead and prove his innocence in a civil action.But, even if we regard the implied confession as a petition which in Hawkins' time had to be accepted as tendered, in modern practice it has been transformed into the formal plea of nolo contendere. Like the implied confession, this plea does not create an estoppel; but, like the plea of guilty, it is an admission of guilt for the purposes of the case. ”
