1 After the discharge of tfie defendant by the district court, as recited in State v. Jamison, 100 Iowa, 342, another information was filed with C. L. Jones, a justice of tfie peace, accusing him of tfie same offense, and to which he entered a plea of guilty. He withdrew this on appeal, and pleaded, not guilty, and that fie had been convicted of tfie identical offense' before tfie mayor of Allison. Tfie defendant having introduced that officer’s record of conviction, tfie state introduced that of the district court, adjudging tfie mayor to have been without jurisdiction. It is urged that this was in the nature of a confession and avoidance of tfie special plea of tfie defendant, and was not admissible without a reply. See Code 1873, section 2718. But the rules of pleading in civil cases have no application to criminal procedure. The statute expressly provides that to tfie plea of former adjudication no replication or further pleading is necessary. Code 1873, section 4349. Any evidence which tended to overcome that plea was admissible.
*3452 II. Tbe record shows conclusively that the former conviction was by a tribunal without jurisdiction, and the court very properly advised the jury to disregard the special plea of the def endant. The only issue was purely one of law, and might have been raised by demurrer, had the facts been fully pleaded. State v. Callendine, 8 Iowa, 289; State v. Redman, 17 Iowa, 829. And when, under the law, or for want of evidence, the plea is not sustained, the court may so charge the jury. State v. Parker, 66 Iowa, 586, Wharton, Criminal Pleading and Practice, 484, and note.
The motion to retax costs was properly overruled. —Affirmed.
