Tabbaa v Nine Network Pty Ltd (No 11)

The case of Tabbaa v Nine Network Pty Ltd involved a defamation claim brought by Mr Tabbaa against Nine Network. The dispute centred on several articles published by the defendant, which Mr Tabbaa alleged were defamatory. The case was heard in the Federal Court of Australia. The primary legal issues the court had to address were whether the basis of quantification of costs could be altered from indemnity to party/party, and whether the pursuit of the claim constituted an abuse of process given the false evidence provided by the plaintiff.

The court examined the nature of the costs order in light of the plaintiff's conduct throughout the litigation. It was established that the defamatory imputations were found substantially true by the jury, and the jury's answers were construed to implicitly find the plaintiff deliberately untruthful. The court also considered that the claim was pursued based on false or misleading evidence, which the plaintiff was aware was false. Given these findings, the court considered whether the pursuit of the claim was an abuse of process, which would warrant a departure from the usual indemnity basis for costs. The court concluded that the plaintiff's actions warranted such a departure, leading to a party/party costs order.

Ultimately, the court determined that the plaintiff's conduct justified altering the usual basis for quantifying costs from indemnity to party/party. The court found that the plaintiff's pursuit of the claim on a knowingly false basis amounted to an abuse of process, justifying the costs order in favour of the defendant. This decision highlights the court's power to adjust costs orders in cases where a party has acted in a manner that constitutes an abuse of the judicial process.
