The orders were taken out by the Commonwealth. Now the Commonwealth applies, pursuant to O. 29, r. 11 of the Rules of this Court ("the slip rule"), for a variation of these orders. The variation is sought to take account of a fact which was not adverted to by the Commonwealth at the time when the appeals were before this Court. The fact is that on 21 September 1982, that is in the period between judgment in the Supreme Court and the appeal coming on for hearing before the Full Court of the Federal Court, the Commonwealth paid $91,990.06 to Mr. McCormack's solicitors in satisfaction of the judgment for $75,000 and interest which had been given in his favour in the Supreme Court and which was subsequently set aside on appeal. The fact that the Commonwealth had made that payment was not disclosed either to the Full Court of the Federal Court or to this Court. Indeed, we are informed that senior counsel who appeared for the Commonwealth on the hearing of the appeal to this Court was not informed that the payment had been made. The Commonwealth has sought to obtain repayment of the $91,990.06 from Mr. McCormack but has not succeeded in its efforts. In the present notice of motion, the Commonwealth seeks an order either varying or adding to the orders already made which will have the effect that there is some final order obliging Mr. McCormack to repay to the Commonwealth the sum of money which was paid to him in satisfaction of the judgment of the Supreme Court which has now been set aside.
