Mallesons Stephen Jaques v Trenorth Ltd

In the matter of Mallesons Stephen Jaques v Trenorth Ltd, the parties were engaged in a legal dispute which ultimately reached the Court of Appeal. Trenorth Ltd sought to recover costs paid to the Krakowskis and its own costs of defending the action brought by the Krakowskis, while Mallesons Stephen Jaques sought repayment of the sums paid under the judgment below. The court was required to determine the appropriate relief in light of the overturned judgment.

The central legal issues before the court were whether Mallesons was entitled to repayment of the sums paid under the judgment that had been set aside and whether interest should be payable on such sums. Trenorth argued for the repayment of costs and interest on the judgment sum, while Mallesons contended that it was entitled to restitution of the amounts paid. The court had to consider the principles of restitution and the appropriate interest rate to apply.

The court found that Mallesons was entitled to an order for the repayment of the sums paid under the erroneous judgment. The principle of restitution was applied, which mandates the restoration of what was wrongly taken from one party and given to another. The court rejected the argument for interest on the judgment sum as misconceived. However, interest on the repaid sums was to be calculated at the rate fixed by the Penalty Interest Rates Act 1983. The court held that it had the power to order such repayment, drawing on precedents such as Burke v Gillett and Commonwealth v McCormack.

The final orders of the court provided that Mallesons was to be repaid the total sum of $1,408,480.25, which included the judgment sum, interest thereon, and the Krakowskis' costs, with interest on the repaid sum calculated at the rate prescribed by the Penalty Interest Rates Act 1983.
