(m) In any court having 2 or more probation officers, the first justice, subject to the approval of the court administrator and the commissioner of probation, may designate 1 probation officer to serve as chief probation officer and may designate other probation officers to serve as assistant chief probation officers, as the first justice deems necessary for the effective administration of justice.
A first justice may recommend to the commissioner of probation the initiation of disciplinary proceedings against a probation officer so promoted under this section; provided, however, that such probation officer shall receive a hearing by the commissioner of probation prior to being discharged; and provided further, that such probation officer may appeal any suspension, discipline or discharge to the court administrator.
