Many Oregon cities have a municipal court, a court in which small offenses are tried to a judge or jury of six. (Portland gave up its municipal court in 1971.) Some municipal courts are courts of record (meaning that they must record their proceedings and comply with some other state requirements), with lawyers as judges; others are not courts of record and can engage any responsible adult to be the judge. Cities that choose to have a municipal court adopt ordinances to establish the court and set down the rules.
Gearhart, that placid coastal village, has a municipal court with an interesting twist that I can't imagine the city fathers and mothers intended when they wrote their code. If you should appear before the municipal court and ask for a jury trial, the city fines the judge $30. It's true! Here's the code section, or check the PDF of the code for yourself (page 53):
§ 32.43 COURT COSTS.
In all cases tried before a jury in the Municipal Court, the Municipal Judge shall add the costs and disbursements of the trial and be fined a sum not exceeding $30.
