Tyne (Trustee) v UBS AG (No 2)

In the case of Tyne (Trustee) v UBS AG (No 2), the dispute arose from the discontinuance of proceedings in the Supreme Court of New South Wales and the subsequent filing of new proceedings in the Federal Court of Australia. The matter was ultimately decided by the Full Court of the Federal Court of Australia. The appellants, Mr. Tyne as trustee of a trust and Ms. Marks, sought to challenge the primary judge's decision that the recommencement of their claims in the Federal Court constituted an abuse of process. They argued that the primary judge erred in law by not recognising that the previous Supreme Court proceedings had not been determined on their merits.

The legal issues before the court included whether the appellants' recommencement of their claims in the Federal Court constituted an abuse of process, and if so, whether the primary judge's decision was correct. The court also needed to consider whether the appellants' conduct, including the delay and duplication of proceedings, amounted to an abuse of process. Furthermore, the court had to assess whether the primary judge's findings on the merits of the appellants' claims were correct, and whether there was any manifest unfairness or oppression in the recommencement of the proceedings.

The Full Court found that the primary judge's decision was correct. The court held that the recommencement of the proceedings in the Federal Court amounted to an abuse of process, as it unnecessarily extended the time taken to resolve the dispute and caused duplication of process. The Full Court emphasised that even a meritorious claim may be dismissed as an abuse of process if it causes unfairness or brings the administration of justice into disrepute. The court also noted that the appellants had delayed the resolution of their claims against UBS by not participating in the Supreme Court proceedings, which contributed to the abuse of process. The Full Court concluded that the primary judge's findings on the merits of the appellants' claims were not in error and that there was no manifest unfairness or oppression in the recommencement of the proceedings.

The appeal was allowed, and the orders made by the primary judge were set aside. In lieu thereof, the interlocutory application was dismissed, and the respondent was ordered to pay the appellants' costs of the appeal, the application for leave to appeal, and the interlocutory application, as agreed or taxed.
