A.   In all prosecutions for violations of ordinances punishable by fine of more than five hundred dollars ($500.00) excluding court costs, or by imprisonment, or by both fine and imprisonment, trial shall be by jury, unless waived by the defendant and the city. If trial by jury is waived, trial shall be to the court.
   B.   At arraignment, the defendant shall be asked whether he demands or waives trial by jury. His election shall be recorded in the minutes of the arraignment and entered on the docket of the court respecting proceedings in the case.
   C.   An election waiving jury trial, made at arraignment, may be changed by the defendant at any time prior to the day for which trial by the court is set; an election demanding jury trial may be changed at any time prior to the commencement of proceedings to impanel the jury for the trial, but if that change occurs after the case has been set for jury trial, it may not thereafter be rechanged so as again to demand trial by jury. (Prior code §§ 12-36, 12-37, 12-38; amd. Ord. 1382, 10-24-1995; 2015 Code)
