In all civil cases, a party may obtain one automatic leave to move or plead by certifying to the Clerk or by motion and order, stating that no previous leave has been taken. Such leave may not exceed twenty-one (21) days.
One additional leave to move or plead may be obtained at the discretion of the assigned judge or magistrate. The request for leave shall be in writing, with notice to other parties, stating the reason for requesting such leave and setting forth the particulars of the prior leave. Such additional leave shall not exceed twenty-one (21) days. A judge, for good cause, may waive any requirement in this paragraph.
