Municipal Courts function as city government's "judicial branch." Municipal courts are not part of the state government courts in Oregon. Not all Oregon cities have a Municipal Court, but those that do, hear cases involving violations of city laws (ordinances) and some state statutes that regulate animal control, fire control, parking, and traffic violations with city limits.
County Courts exist in seven eastern Oregon counties. The Board of Commissioners in those counties acts as the County Court, each with a county judge who also chairs the county commission and has limited judicial functions. The county judge, whose primary job involves non-judicial administrative responsibilities as chair of the county commission, may handle either probate and juvenile cases, or both, within the county.
Justice Courts are funded by county government, but are under the administrative authority of the State of Oregon, which also pays the salaries of the 13 elected Justice Court judges and their staff. The judge of a justice court is called a Justice of the Peace, and is elected to serve for six years. Justice Courts are the equivalent of city government municipal courts in that they hear cases involving minor traffic and boating violations, fish and game offenses, small civil claims, violations of some county ordinances (excessive noise, dogs running at large), and can perform weddings in a specific section of the county to which the justice court is assigned. Most misdemeanors, all felonies, most civil cases, and some appeals of justice court decisions are heard in the state circuit courts.
Tribal Courts are an important part of tribal self-government in Oregon’s Indian Nations. Most tribes have their own constitutions and justice codes that determine how tribal courts resolve civil and criminal matters that occur on reservation lands and property. Some tribes choose to use native customs and traditional forms of dispute resolution and other tribes use an adversarial process (involving a plaintiff and defendant) to settle disputes.
Federal Courts (United States district courts) are the "trial courts" of the United States federal court system. The United States District Court for the District of Oregon has four courthouses – located in Eugene, Medford, Pendleton, and Portland. Federal district courts hear cases related to federal law, administrative actions of federal agencies, or the United States Constitution. The federal appellate court, called the Ninth Circuit Court of Appeals, is based in San Francisco. It has offices in and hears appeals from lower federal courts in states belonging to the “Ninth Circuit” including Alaska, Arizona, California, Guam, Hawaii, Idaho, Montana, Nevada, Northern Marianas Islands, Oregon, and Washington. Decisions of the federal appellate courts may be appealed to the United States Supreme Court.
Federal courts also handle all bankruptcy cases. The Federal Bankruptcy Court for the District of Oregon hears cases in two locations – Portland and Eugene.
