ANZ Banking Group Ltd v Alirezai; Alirezai v ANZ Banking Group Ltd

The matter before the court involved ANZ Banking Group Ltd and Mr Alirezai, who were in dispute over a mortgage arrangement where Mr Alirezai had acted as a surety for a company's debts. The case was heard in the High Court of Australia, which was required to determine the extent to which the bank had a duty to ensure that the surety was fully informed about the financial dealings between the debtor and the bank, and whether the bank was required to provide independent legal advice to the surety. The High Court was also required to consider whether the principles established in earlier cases, such as Garcia v National Australia Bank Ltd and Royal Bank of Scotland v Etridge (No 2), were limited to marriage or marriage-like relationships, or if they could be extended to other non-commercial relationships.

The primary legal issues before the court were whether the bank should have been aware that Mr Alirezai was in a position of special disadvantage and whether the bank had a duty to disclose the true financial position of the borrower and the bank to the surety. The court also had to determine if the principles of undue influence and unconscionable dealing, as established in earlier cases, could be extended beyond marriage or marriage-like relationships. The central question was whether the bank's failure to ensure that Mr Alirezai had independent legal advice amounted to unconscionable conduct, and if the bank was deemed to have notice of the special disadvantage where the relationship between the surety and the debtor was non-commercial.

The High Court found that the bank should have been aware that Mr Alirezai was in a position of special disadvantage due to his relationship with the company's director, who was also his close friend. The court held that the bank had a duty to ensure that the surety was fully informed about the financial dealings between the debtor and the bank, and that this duty extended to non-commercial relationships. The court also determined that the bank had a responsibility to disclose the true financial position of the borrower and the bank to the surety, especially where the proposed surety was otherwise unable to make an informed judgment as to their own best interests. The High Court concluded that the principles of undue influence and unconscionable dealing were not limited to marriage or marriage-like relationships and could be applied to other non-commercial relationships.

The High Court dismissed the appeal and ordered that costs be paid by the appellant. This decision reinforces the importance of banks ensuring that sureties are fully informed about the financial dealings between the debtor and the bank, and highlights the need for banks to take reasonable steps to ensure that sureties receive independent legal advice, particularly in situations where the surety may be in a position of special disadvantage.
