N.M. R. Crim. P. Magist. Ct. 6-603
Juries in the magistrate court shall hear the evidence in the action which shall be delivered in public in its presence. After hearing the evidence, the members of the jury shall be kept together until they unanimously agree on a verdict or are discharged by the magistrate. When the magistrate is satisfied that there is no reasonable probability that a jury can agree unanimously on a verdict after a reasonable time, the magistrate may discharge it and summon a new jury unless the parties agree that the magistrate may render judgment.
