Oregon Revised Statutes Justice Courts § 51.037

Any city may enter into an agreement pursuant to ORS 190.010 with the county in which a justice of the peace district is located for the provision of judicial services. A justice of the peace providing services to a city pursuant to such an agreement shall have all judicial jurisdiction, authority, powers, functions and duties of the municipal court of the city and the judges thereof with respect to all and any violations of the charter or ordinances of the city. Unless the agreement provides otherwise, and subject to the provisions of ORS 153.640 to 153.680, all fines, costs and forfeited security deposits collected shall be paid to the prosecuting city, and the city shall reimburse the county providing judicial services for expenses incurred under the agreement. The exercise of jurisdiction under such an agreement by a justice of the peace shall not constitute the holding of more than one office.
