Which court has exclusive original jurisdiction of criminal cases arising from city ordinances?

Municipal Courts hold exclusive original jurisdiction over criminal cases that arise from city ordinances. This jurisdiction is specifically established to handle violations of local laws, making Municipal Courts unique in their focus on city-related misdemeanors. These courts are created by city governments and are tasked with addressing offenses such as traffic violations, noise complaints, and other ordinance violations within their respective municipalities.

District Courts, while having significant jurisdiction over felony cases and other serious matters, do not specifically handle municipal ordinance violations. County Courts encompass a broader range of jurisdiction that may include misdemeanors, but they do not have exclusive rights over city ordinance cases. Justice Courts deal primarily with lower-level civil and criminal matters but do not have the authority to exclusively manage violations related to city ordinances, as that responsibility resides with Municipal Courts. Thus, the function and authority of Municipal Courts make them the correct answer in this context.
