All prosecutions for violations of ordinances of this city shall be styled "The City of Eufaula, Oklahoma vs. (naming defendant or defendants)". Except as provided hereinafter, prosecution shall be initiated by the filing of a written complaint, subscribed and verified by the person making complaint, and setting forth concisely the offense charged. A complaint may be amended in matter of substance or form at any time before the defendant pleads, without leave, and may be amended after plea on order of the court where the same can be done without material prejudice to the rights of the defendant; no amendment shall cause any delay of the trial, unless good cause is shown by affidavit.
