ORS § 399.440
Efficiency and medical examining boards appointed by the Governor hereby are vested with the powers of courts of inquiry and courts-martial. Such boards shall follow the practice and procedure prescribed by applicable federal and state laws and regulations. Any officer ordered to appear before such a board shall be allowed to appear in person or by counsel, to cross-examine witnesses and to call witnesses on behalf of the officer. The officer shall at all stages of the proceeding be allowed full access to records pertinent to the case and be furnished copies of same. Failure to appear before such examining board shall be sufficient ground for a finding by such board that the officer ordered to appear be discharged from the service of the state. If the findings of such board are unfavorable to an officer and are approved as provided by applicable laws of the United States or this chapter and ORS chapters 396 and 398, the Governor shall relieve the officer from duty and shall give the officer a discharge in such form as may be appropriate. If the discharge of an officer is recommended solely because of physical inability to perform active service, such officer may be transferred to the retired reserve if eligible.
