—(1) Subject to Order 15, Rules 6, 6A, 7 and 8, and this Rule, the Court may at any stage of the proceedings allow the plaintiff to amend his writ, or any party to amend his pleading, on such terms as to costs or otherwise as may be just and in such manner (if any) as it may direct.
(2) Where an application to the Court for leave to make the amendment mentioned in paragraph (3), (4) or (5) is made after any relevant period of limitation current at the date of issue of the writ has expired, the Court may nevertheless grant such leave in the circumstances mentioned in that paragraph if it thinks it just to do so.
(3) An amendment to correct the name of a party may be allowed under paragraph (2) notwithstanding that it is alleged that the effect of the amendment will be to substitute a new party if the Court is satisfied that the mistake sought to be corrected was a genuine mistake and was not misleading or such as to cause any reasonable doubt as to the identity of the person intending to sue or, as the case may be, intended to be sued.
(4) An amendment to alter the capacity in which a party sues (whether as plaintiff or as defendant by counterclaim) may be allowed under paragraph (2) if the capacity in which, if the amendment is made, the party will sue is one in which at the date of issue of the writ or the making of the counterclaim, as the case may be, he might have sued.
(5) An amendment may be allowed under paragraph (2) notwithstanding that the effect of the amendment will be to add or substitute a new cause of action if the new cause of action arises out of the same facts or substantially the same facts as a cause of action in respect of which relief has already been claimed in the action by the party applying for leave to make the amendment.
