O'Connor v O'Connor

The appeal in *O'Connor v O'Connor* concerned a claim for damages arising from an alleged breach of an agreement to issue shares. The primary judge had dismissed the plaintiffs' claim but had also indicated that an alternative case, which was not fully pursued at trial, might have succeeded. The appeal to the Court of Appeal of New South Wales raised questions about whether the primary judge should have upheld the claim based on this alternative case, whether that alternative case was the subject of a concession made at trial, and whether that concession had been wrongly elicited by the primary judge. The plaintiffs also sought to withdraw their concession on appeal.

The central legal issues before the Court of Appeal were: first, whether the primary judge erred in failing to uphold the plaintiffs' claim on the basis of the alternative case; second, whether the concession made at trial regarding the alternative case was validly made and binding; and third, whether the Court of Appeal should permit the withdrawal of that concession on appeal.

The Court of Appeal dismissed the appeal. The reasoning of the court, though not detailed in the provided text, appears to have focused on the binding nature of the concession made at trial and the reluctance of appellate courts to permit the withdrawal of such concessions, particularly when they were central to the proceedings below and the primary judge's findings. The court likely applied principles relating to the finality of litigation and the proper role of an appellate court in reviewing decisions based on concessions made by the parties.

The appeal was dismissed with costs.
