Primus Telecommunications Pty Ltd v Kooee Communications Pty Ltd

Primus Telecommunications Pty Ltd and Kooee Communications Pty Ltd were engaged in litigation concerning claims arising from a Separation Deed and subsequent conduct. The dispute was heard in the Supreme Court of Victoria, which had to determine the appropriateness of the Anshun principle and whether the proceeding constituted an abuse of process. The Anshun principle refers to the situation where a party should not be allowed to litigate issues that have already been determined in a previous proceeding, to prevent inconsistent judgments. Kooee argued that Primus should have raised its current claims in the New South Wales Supreme Court proceeding.

The court considered whether it was unreasonable for Primus to defer raising its current claims and found that it was not unreasonable to do so. The critical facts in the current proceeding were different from those in the New South Wales litigation and there was no risk of inconsistent judgments. The court also found that the proceeding did not amount to an abuse of process, as the matters being litigated were distinct from those resolved in the earlier proceeding. The High Court's decision in Walton v Gardiner was not applicable, as the matters were different in character.

The Supreme Court of Victoria dismissed Kooee's motion and ordered Kooee to pay Primus' costs associated with the motion. The court held that the critical facts required to make out the current application did not require examination in the earlier litigation, and no judgment or order could be made in the current proceeding which would conflict with any judgment or order made in New South Wales.
