A statute, rule, or order of the Court may require a party to file a pleading. A party may amend a pleading without leave of the Court until the tenth calendar day prior to the date set for hearing on the matter, unless otherwise ordered by the Court. Thereafter, a party may amend a pleading only by written consent of the opposing party or by leave of the Court for good cause shown. If a party amends a pleading to which the opposing party is required to respond or reply, a response or reply to the amendment shall be filed within seven (7) calendar days of service of the amendment unless otherwise ordered by the Court.
