(1) A party may amend a pleading once, at any time before the pleadings close, without the leave of the Court.
(2) However, a party may not amend a pleading if the pleading has previously been amended in accordance with the leave of the Court.
(3) A party may further amend a pleading at any time before the pleadings close if each other party consents to the amendment.
(4) An amendment may be made to plead a fact or matter that has occurred or arisen since the proceeding started.
