Rule 3-604. Trial by jury.

Juries in the metropolitan 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 five of them agree upon a verdict or are discharged by the judge. Whenever the judge is satisfied that five jurors cannot agree on a verdict after a reasonable time, he may discharge it and summon a new jury unless the parties agree that the judge may render judgment.
