North Dakota Century Code Title 29. Judicial Procedure, Criminal § 29-22-24. Finding on charge of previous conviction

Whenever the fact of a previous conviction of another offense is charged in the information or indictment, the jurors, if they find a verdict of guilty of the offense with which the defendant is charged, also must find whether or not the defendant has suffered such previous conviction, unless the answer of defendant admits the charge. In addition to the verdict of “guilty”, the verdict of the jurors upon a charge of previous conviction may be, “we also find the charge of previous conviction true”, or “we also find the charge of previous conviction not true”, as they find that the defendant has or has not suffered such conviction.
