(2) The Oregon Health Authority may order the change, in all or part, of the purpose and use of any state institution being used as an institution for the care and treatment of persons with mental illness in order to care for persons committed to its custody whenever the authority determines that a change in purpose and use will better enable this state to meet its responsibilities to persons with mental illness. In determining whether to order the change, the authority shall consider changes in the number and source of the admissions of persons with mental illness.
