ORS § 408.570
When a veteran who has been adjudged under ORS 426.130 to be a person with mental illness is eligible for treatment in a United States veterans facility and commitment is necessary for the proper care and treatment of such veteran, the Oregon Health Authority or community mental health program director, as provided under ORS 426.060, may, upon receipt of a certificate of eligibility from the United States Department of Veterans Affairs, assign the person to the United States Department of Veterans Affairs for care, custody and treatment in a United States veterans facility. Upon admission to any such facility, the veteran shall be subject to the rules and regulations of the United States Department of Veterans Affairs and provisions of ORS 426.060 to 426.395 and related rules and regulations of the Oregon Health Authority. The chief officer of such facility shall be vested with the same powers exercised by superintendents of state hospitals for persons with mental illness within this state with reference to the retention, transfer, trial visit or discharge of the veteran so assigned. The commitment of a veteran to a veterans facility within this state by a court of another state under a similar provision of law has the same force and effect as if the veteran was committed to a veterans facility within that other state.
