National Australia Bank Limited v Wehbeh

The case of National Australia Bank Limited versus Wehbeh involved a dispute between the bank and the wife, who was both a mortgagor under a home loan and a guarantor of a business loan to her husband's company. The bank sought possession of the land under the mortgage and a judgment for the debt due under the guarantee. The wife raised several defences, including the claim that she was under a special disability, that it was unconscientious for the bank to rely on the default under the home loan to enforce the mortgage, and that there was undue influence from her husband in procuring the guarantee. She also argued that she was a volunteer in the transaction and that the bank had knowledge of any undue influence. The bank, however, contended that the mortgage and guarantee were prima facie enforceable under the Transfer of Land Act 1958 section 78.

The central legal issues before the court were whether the wife was under a special disability, which would render the mortgage and guarantee unenforceable, and whether the bank's reliance on the default under the home loan to enforce the mortgage was unconscientious. Additionally, the court had to determine if there was undue influence from the husband in procuring the guarantee and if the bank had knowledge of any undue influence. The wife's argument that she was a volunteer in the transaction was also considered.

In delivering its judgment, the court found that the wife was not under a special disability. It held that the mortgage and guarantee were enforceable as prima facie valid under the relevant legislation. The court further determined that it was not unconscientious for the bank to rely on the default under the home loan to enforce the mortgage. Regarding undue influence, the court found that there was no evidence to support the wife's claim that her husband exerted undue influence over her in procuring the guarantee. The court also concluded that the bank did not have knowledge of any undue influence. The wife's argument that she was a volunteer in the transaction was rejected, as the court found that she had willingly participated in the transaction.

The court made orders in favour of the bank, granting possession of the land under the mortgage and a judgment for the debt due under the guarantee. The wife's defences were dismissed, and the bank's claims were upheld in their entirety.
