ORS § 221.919
The marshal shall be chief of police and shall have control over all police officers when on duty. The marshal shall be a conservator of the peace, and shall arrest all persons guilty of a breach thereof, or of violations of the city ordinances, and take them before the recorder for trial. The marshal shall make and enforce the collection of all delinquent city taxes, as the collection of delinquent county taxes is enforced, and shall perform such other duties as may be required of the marshal by the common council. The marshal may suspend any police officer for negligence or violation of duty until the case may be examined and determined by the council. On complaint being made, charging the marshal with malfeasance or nonfeasance in office, the alderpersons, by a unanimous vote without the concurrence of the mayor, or by a majority vote with the concurrence of the mayor, may remove the marshal from office at any regular meeting, after giving the marshal an opportunity to be heard in the defense of the treasurer, provided they find the charge is true.
