Commissioner for Fair Trading v Jonval Builders Pty Ltd (No 3)

The dispute involved the Commissioner for Fair Trading and Jonval Builders Pty Ltd, with the Commissioner seeking clarification on the calculation of post-judgment interest under the Civil Procedure Act 2005 (NSW). The case was heard in the Supreme Court of New South Wales. The Commissioner, having successfully obtained judgment against Jonval Builders, sought to ensure that post-judgment interest was calculated correctly, particularly in circumstances where the judgment required Jonval Builders to pay named consumers who were not parties to the proceedings. The core issue was whether the judgment remained unpaid until the payments were made to the consumers.

The court had to determine the meaning of "unpaid" in the context of the Act and whether the judgment remained unpaid despite the defendants having made payments into court, albeit under a conditional stay. The court also had to consider whether the judgment was considered unpaid until the conditions of the stay were satisfied, and if so, how this affected the calculation of post-judgment interest. The question of when the interest should commence and whether it should be calculated from the date of the original judgment or from the date the conditions of the stay were met was central to the case.

The court held that the judgment remained unpaid until the conditions of the stay were satisfied and the payments were made to the consumers. The court found that post-judgment interest should only commence from the date when the judgment was fully satisfied. The court reasoned that until the conditions of the stay were met and the consumers received their payments, the judgment could not be considered fully satisfied. Consequently, the interest was not payable until the consumers received their payments, and the calculation of post-judgment interest should reflect this timeline. The court's decision clarified that the statutory language of "unpaid" encompasses situations where the judgment conditions are not fully met, even if interim payments are made into court.

The court ordered that the post-judgment interest be calculated from the date the consumers received their payments, and not from the date of the original judgment. This ruling provided clarity for future cases involving similar circumstances and ensured that the interpretation of "unpaid" aligns with the practical outcomes of the judgment enforcement process.
