Miller & Associates Insurance Broking Pty Ltd v BMW Australia Finance Limited

Miller & Associates Insurance Broking Pty Ltd (Miller) and BMW Australia Finance Limited (BMW) were the parties involved in this dispute before the High Court of Australia. The core of the disagreement concerned the enforceability of a guarantee provided by Miller in favour of BMW, relating to a loan facility extended to a third party, a company known as "the Company". Miller sought to avoid liability under the guarantee, alleging that BMW had breached its duty of care to Miller by failing to disclose material information regarding the Company's financial position and the risks associated with the loan.

The High Court was required to determine whether BMW owed a duty of care to Miller, as a guarantor, to disclose material information about the principal debtor's financial circumstances. Specifically, the Court considered whether the relationship between BMW and Miller, in the context of the guarantee, gave rise to such a duty, and if so, whether BMW had breached that duty. The Court also had to consider the nature and scope of any such duty, and whether the terms of the guarantee itself might have excluded or limited any such obligation.

The High Court ultimately held that BMW did not owe a duty of care to Miller to disclose material information regarding the Company's financial position. The Court reasoned that the relationship between a creditor and a guarantor, in the absence of special circumstances, does not ordinarily give rise to a duty on the creditor to disclose information about the principal debtor's financial standing. The Court emphasised that a guarantor is expected to make their own inquiries and assess the risks involved, and that the terms of the guarantee itself, which typically place the onus on the guarantor to satisfy themselves about the debtor's position, were critical. The Court found that the standard commercial relationship and the terms of the guarantee did not create the necessary proximity or assumption of responsibility for BMW to owe a duty of disclosure to Miller.

The High Court dismissed Miller's appeal, upholding the decision of the lower court.
