Failure to appear for duty; excuses; penalty for being absent without leave
Section 47. No officer or enlisted person of the armed forces of the commonwealth, not on leave of absence, shall be excused from duty if ordered out under section 38, 40 or 41 except upon a physician's certificate of disability. If an officer or enlisted person is absent without leave and does not produce that certificate to the commanding officer, that service member may be punished in accordance with this chapter for desertion or absence without leave. Sickness shall not be an excuse unless the service member procures that certificate or satisfies the court-martial that the service member was unable to procure the certificate.
