Ga. Unif. Mun. Ct. R. 4.1
Unless provided by approved internal procedures or pursuant to assignment by the chief judge, cases shall not be assigned to a particular judge. Provided, however, that once any judge has first heard sworn testimony or made any ruling in a case other than the granting of an arrest or search warrant, the setting of bail and the initial finding of probable cause, or the granting of a continuance, that case shall thereafter be considered only by that judge, except upon the approval of that judge. In municipal courts served by more than one judge, the clerk of court shall schedule the presiding of those judges over the various court calendars according to a plan approved by a majority of those judges. This rule shall not apply to probation revocation hearings.
