Glad Cleaning Service Pty Ltd v Vukelic

Glad Cleaning Service Pty Ltd and others brought a claim against Vukelic in the Federal Circuit Court of Australia. The dispute involved an issue of unjust enrichment, where the second plaintiff had paid a workers compensation settlement to the defendant without deducting monies owed to the Commonwealth. Centrelink had issued a Recovery Notice to the second plaintiff, requesting payment of $63,603.12 before the payment to the defendant. The second plaintiff complied with this notice by paying the sum to Centrelink after making the payment to the defendant. The second plaintiff sought restitution, claiming a mistake of fact or law was made by their claims officer, leading to a miscalculation of the sum to be paid to the defendant.

The court was required to determine whether there was a mistake of fact or law made by the second plaintiff's claims officer that could serve as a defence to the claim for restitution. The court also had to assess if the miscalculation by the second plaintiff's claims officer constituted a valid defence to the claim. The court found that there was no defence to the claim for restitution, as the mistake of fact or law made by the claims officer did not absolve the second plaintiff of its obligation to pay the sum owed to the Commonwealth.

The court's reasoning was based on the principle that the second plaintiff had an obligation to ensure that monies owed to the Commonwealth were deducted from the settlement before making the payment to the defendant. The court found that the mistake of fact or law made by the claims officer did not negate this obligation. The court held that the second plaintiff was unjustly enriched by the amount of $63,603.12, and as such, judgment was entered for the plaintiffs in the amount of $63,603.12 plus interest accrued up to judgment.
