Commonwealth of Australia v Winston

The Court of Appeal of New South Wales, comprising Gleeson, Leeming and Adamson JJA, considered an appeal by the Commonwealth of Australia against orders made by the Supreme Court. The dispute concerned the Commonwealth's application to amend its notice of motion to include a claim that was statute-barred, following an earlier grant of an extension of time.

The central legal issues before the Court of Appeal were whether a proposed amendment to a pleading, sought to be introduced after the expiry of the limitation period, pleaded the same cause of action as the original claim or a new cause of action arising out of the same or substantially the same facts. The Court was also required to consider the principles governing the determination of whether a proposed amendment arises out of substantially the same facts and whether a further extension of time should be granted in the circumstances.

The Court of Appeal allowed the appeal, finding that the proposed amendment did not arise out of substantially the same facts as the original claim. The Court set aside the previous orders and dismissed the amended notice of motion, ordering Mr Winston to pay the Commonwealth's costs of the application for leave to appeal and the appeal. Mr Winston was directed to file and serve any amended statement of claim by a specified date.
