On the first question, there was little controversy. The applicant submitted that the appeals were arguable, and the respondent accepted that position. The substantive appeal had already been heard and was reserved. There was no competency objection or similar challenge to the costs appeal. Wheatley J said it was generally not appropriate, at this stage, to embark on a close consideration of prospects. The court was satisfied that each appeal raised reasonably arguable grounds and had some rational prospect of success.
The real contest was the second question, the balance of convenience. The applicant argued that he would suffer serious adverse consequences that could not be addressed on appeal because he was in financial hardship and unable to pay the lump-sum costs sought. He also argued that there was no identified prejudice to the respondent if a stay were granted, that there was little utility in enforcing the costs order immediately given his financial circumstances, and that bankruptcy could affect his ability to prosecute the costs appeal.
The respondent’s main points were narrower. It said the applicant had not adequately disclosed his financial position and had not proved a real risk that the respondent would proceed by way of bankruptcy. It accepted that if the court were satisfied there was a real risk of bankruptcy, the appeal would likely be rendered nugatory. So the dispute turned on whether that risk had been shown.
Wheatley J accepted the applicant’s financial evidence. The court found that he would not be able to pay the lump-sum costs order in the claimed amount, or a similar amount. The court then considered whether there was a real risk of bankruptcy. It accepted there was no direct evidence of a bankruptcy notice or an express statement from the respondent that bankruptcy would be pursued. But the court said the question was whether there was an objective likelihood of bankruptcy proceedings, not mere speculation. In the particular circumstances, the applicant was in receipt of Centrelink special benefits, was impecunious, and lacked property, income and useful bank balances. The court reasoned that other enforcement measures would be unlikely to be of benefit to the respondent. On that basis, it held that the inference was open that there was a real risk the respondent would proceed by way of bankruptcy if the costs were quantified and enforcement followed.
The court also rejected the respondent’s submission that prejudice to the respondent was irrelevant. Referring to earlier authorities, Wheatley J held that prejudice to the other party was relevant, even if the applicant still bore the onus of showing a proper basis for a stay. On the material before the court, the respondent would not suffer prejudice from a delay in recovery if a stay were granted.
That did not mean the applicant obtained everything he wanted. The court drew a distinction between the Registrar’s determination of the lump-sum amount and the exchange of costs material between the parties. It held that it was in the interests of justice for the parties to complete the quantification process on their side now, while the issues were relatively fresh. If the applicant lost the appeals, the matter could then be reactivated promptly and referred to the Registrar without waiting for the parties to reconstruct the costs issues later. If the applicant succeeded, some work might prove wasted, but the court considered that an acceptable balance in the circumstances.
The result was a partial stay. Order 4 of the 19 December 2025 orders, which referred the determination of the fixed lump-sum amount to the Registrar, was stayed until the later of the determination of the appeal in either WAD91/2025 or NSD2439/2025. Order 3, requiring the applicant to file and serve a costs response, was not stayed. Instead, the time for compliance was extended to 4:30 pm AWST on 6 February 2026. The costs of the interlocutory stay application were reserved.
The court also rejected the applicant’s submission that his status as a whistleblower was relevant to the stay application. The judge said no authority had been cited for that proposition and that the relevant question remained whether this was an appropriate case to grant a stay under the ordinary principles.
