Thoroughgood v Emmerton

In *Thoroughgood v Emmerton*, the New South Wales Court of Appeal considered an appeal concerning the amendment of a defence. The specific dispute involved the circumstances under which a party should be permitted to amend their defence, particularly when such an amendment might introduce new issues or alter the nature of the defence late in proceedings.

The primary legal issue before the Court of Appeal was whether the primary judge had erred in exercising their discretion to disallow the proposed amendment to the defence. This required the Court to consider the principles governing the amendment of pleadings, including the need for the amendment to be bona fide, the potential prejudice to the opposing party, and whether the amendment would likely lead to a just determination of the substantive issues in dispute.

The Court of Appeal affirmed the principles that amendments to pleadings should be allowed unless they are vexatious, an abuse of process, or would cause unfair prejudice that cannot be adequately compensated by costs. In this instance, the Court found that the primary judge had correctly applied these principles and that there was no error in the exercise of discretion in refusing the amendment. The proposed amendment was considered to be an attempt to raise a substantially different defence at a late stage, which would have caused significant prejudice to the plaintiff.

Consequently, the appeal was dismissed with costs.
