Limitation Act 1981

If a court would, but for the expiry of a relevant period of limitation after the day a proceeding in the court has commenced, allow a party to amend a document in the proceeding, the court shall allow the amendment to be made if it is satisfied that no other party to the proceeding would by reason of the amendment be prejudiced in the conduct of that party's claim or defence in a way that could not be met by an adjournment, an award of costs or otherwise.

This section does not apply to an amendment in a proceeding commenced before the commencement of this section.
