Cockburn v GIO Finance Ltd (No 2)

The Court of Appeal of New South Wales heard an appeal concerning equitable contribution and recoupment. The dispute involved a mortgagor, Mr. Cockburn, and an insurance company, GIO Finance Ltd, in relation to a mortgage and guarantee that were alleged to be void ab initio due to undue influence. The central question was whether GIO Finance Ltd had suffered a loss upon discharging the mortgage, and conversely, whether Mr. Cockburn had suffered a loss under the void mortgage. The court also considered whether the solicitor involved and GIO Finance Ltd bore co-ordinate liabilities to rectify the same loss, and if so, whether the solicitors were liable to contribute.

The primary legal issues before the court were: (1) whether GIO Finance Ltd had suffered a compensable loss in discharging the mortgage, given its void nature; (2) whether Mr. Cockburn had suffered a loss under the void mortgage; and (3) whether the solicitor and GIO Finance Ltd were under co-ordinate liabilities to make good the one loss, thereby giving rise to a claim for contribution against the solicitor.

The court reasoned that for a claim of equitable contribution to arise, there must be a common liability to make good the same loss. In this instance, the court found that GIO Finance Ltd had not suffered a loss because the mortgage and guarantee were void from the outset, meaning there was no valid debt to discharge. Consequently, there was no common liability between GIO Finance Ltd and the solicitor to make good a loss, and therefore, no basis for a claim of contribution. The appeal was upheld, and specific orders were made by the court.
