R.I. Gen. Laws § 30-3-22
The physical fitness for service of commissioned officers or warrant officers of the national guard shall be determined by a board of five (5) medical persons, who shall be appointed by the governor for that purpose. Two (2) of the medical persons shall be selected by the governor and two (2) shall be selected by the officer under examination. The four (4) medical persons shall select a fifth medical person. The officer shall submit his or her selections to the governor within ten (10) days of receipt of notice that he or she is to be examined for physical fitness. Failure of the officer to submit his or her selections to the governor within the prescribed period of time shall be deemed to have been a waiver of his or her rights and the governor shall select the remaining members of the examining board. The findings and recommendations of the board shall be transmitted to the governor. If the officer is found to be physically unfit for service by a majority vote of the examining board, and the finding is approved by the governor, the officer shall be discharged from the national guard, subject to the provisions of § 30-3-39.
