Municipal courts are courts of limited jurisdiction that typically hear cases involving:

• Misdemeanors, including traffic crimes like DUII and reckless driving
• Traffic violations such as speeding, failing to obey traffic signals, and driving while suspended
• Civil infractions under municipal codes
• Municipal judges are appointed by city councils or elected by city voters. There are over 130 municipal courts in Oregon.

The OMJA is a nonprofit organization governed by a board of directors and officers elected by the membership at annual conferences.
