Conference & Exhibition Organisers Pty Ltd v Johnson

The appeal in *Conference & Exhibition Organisers Pty Ltd v Johnson* concerned the application of *Anshun* estoppel. The appellant, Conference & Exhibition Organisers Pty Ltd, sought to set aside a District Court judgment and have two preliminary questions answered in its favour. The dispute arose from the appellant's contention that the respondents' claims were barred by an earlier settlement and consent judgment in the Local Court.

The central legal issue before the Court of Appeal was whether the appellant had acted unreasonably in not raising the claims that formed the basis of the District Court proceedings in the earlier Local Court proceedings, which had been settled by consent judgment. This required the court to consider the principles of *Anshun* estoppel, particularly whether the earlier consent judgment gave rise to issue estoppels and whether the respondents' current claims were so closely connected to the subject matter of the earlier proceedings that it would have been unreasonable not to have raised them then.

The Court of Appeal reasoned that the earlier consent judgment in the Local Court did give rise to issue estoppels, as it resolved common factual controversies between the parties. However, the court found that there was no risk of inconsistent judgments. Crucially, the court determined that it would not have been unreasonable for the appellant to have separately pursued the later claims. This was because raising those claims in the earlier Local Court proceedings would have necessitated refusing the settlement, delaying those proceedings, and requiring a transfer to the District Court. The court concluded that the appellant acted reasonably in settling the earlier proceedings and separately pursuing the later claims.

Consequently, the appeal was allowed. The judgment for the respondents in the District Court and the answers to the two preliminary questions were set aside. The two preliminary questions were answered in the negative, and the respondents were ordered to pay the appellant's costs of the notice of motion in the District Court and the costs of the appeal.
