Bank of Western Australia Ltd v Tannous

The case of Bank of Western Australia Ltd v Tannous involves a dispute over the unjustness of a contract under the Contracts Review Act 1980. The primary issue was whether an advance used to pay out an existing mortgage debt rendered a prior mortgage unjust. The court also had to determine if the prior mortgagee should be joined to the proceedings and whether the unjustness of the prior mortgage constituted a justiciable issue between the borrowers and the prior mortgagee. The case revolved around whether the unjustness of the prior mortgage should be determined as part of the relief granted in respect of the unjustness of the later contract.

The legal issues that the court needed to resolve were whether the prior mortgage was rendered unjust by the use of the advance to pay out the existing mortgage debt, and if the prior mortgagee should be included in the proceedings. Additionally, the court had to examine whether the unjustness of the prior mortgage was a matter that could be decided upon between the borrowers and the prior mortgagee. Finally, the court had to consider if the determination of the unjustness of the prior mortgage should be part of the relief granted in respect of the unjustness of the later contract.

The court determined that the prior mortgage was indeed unjust due to the use of the advance to pay out the existing mortgage debt. It held that the prior mortgagee should not be joined to the proceedings as it was not a necessary party to the dispute. The court also found that the unjustness of the prior mortgage was a justiciable issue that could be decided upon between the borrowers and the prior mortgagee. Finally, the court ruled that the unjustness of the prior mortgage should be determined as part of the relief granted in respect of the unjustness of the later contract. This approach ensured that all relevant aspects of the unjust contract were addressed in a single proceeding.

The final orders of the court were that the prior mortgage was declared unjust, the prior mortgagee was not required to be joined to the proceedings, and the determination of the unjustness of the prior mortgage was to be included as part of the relief granted in respect of the unjustness of the later contract. This decision provided clarity on the scope of relief that could be granted under the Contracts Review Act 1980 in cases involving multiple unjust contracts.
