The proceedings, findings and sentences of court-martial as reviewed and approved, as required by sections 40.005 to 40.490, and all dismissals and discharges carried into execution under sentences by courts-martial following review and approval, as required by sections 40.005 to 40.490, are final and conclusive. Orders publishing the proceedings of courts-martial and all action taken pursuant to those proceedings are binding upon all departments, courts, agencies, and officers of the state subject only to action upon a petition for a new trial or action by the governor as provided in sections 40.220 and 40.225; provided, however, that nothing in sections 40.005 to 40.490 shall be construed to prevent petition to appropriate state or federal courts for relief on questions of law.
