Art. 333.  Crier

The crier of a court shall attend all sessions thereof; under the direction of the judge shall open and close court at each session, and maintain order and decorum in the court room; and shall perform such other duties as are assigned to him by law, the court, or the sheriff.

The crier of a trial court, when requested to do so, shall call all witnesses in the building whose testimony is desired by the court or by a party.

When a court has no crier, and there is no deputy sheriff available for such duty, the sheriff shall perform the duties of crier.
