Section 1304. Time for rendering judgment or decision

If a jury trial is not demanded or directed as provided in § 1303, the
  court  must  render  judgment  within thirty days from the time when the
  case is submitted for that purpose, except when further time is given by
  the consent of the parties. If no decision is rendered within  the  time
  thus  limited,  the  case  shall  be placed upon such calendar as may be
  provided by rule.
