Rippon v Chilcotin Pty Ltd

In *Rippon v Chilcotin Pty Ltd*, the plaintiffs sought to re-litigate an issue they had previously lost in earlier proceedings. The defendant, Chilcotin Pty Ltd, was not a party to those earlier proceedings. The primary judge had dismissed the plaintiffs' action on the basis that it constituted an abuse of process.

The central legal issue before the Full Court of the Supreme Court of Victoria was whether the plaintiffs' current action, brought against a new defendant but seeking to re-litigate a matter already decided against them, was an abuse of process, specifically in relation to the doctrine of *res judicata*. The court had to consider the circumstances in which a party might be prevented from bringing a claim that, while not technically bound by *res judicata* due to the different defendant, sought to relitigate an issue already determined.

The Full Court reasoned that while *res judicata* strictly applies between the same parties or their privies, the court has an inherent power to prevent an abuse of its process. In this instance, the court found that the plaintiffs were attempting to circumvent the earlier adverse finding by bringing a new action against a different party. This was considered an abuse of process because it undermined the finality of judicial decisions and wasted court resources. The court applied the principle that a party should not be permitted to relitigate issues that have been finally determined, even if the new proceedings involve a different defendant, where the purpose is clearly to avoid the consequences of the earlier judgment.

The appeal was allowed, and the orders made by the Full Court reflected this determination.
