Hacide Pty Ltd v Commonwealth Bank

Hacide Pty Ltd (the appellant) appealed to the New South Wales Court of Appeal against a decision of the Supreme Court of New South Wales. The dispute concerned the appellant's liability to the Commonwealth Bank (the respondent) under a guarantee. The appellant argued that it was not liable under the guarantee due to certain conduct of the respondent.

The primary legal issue before the Court of Appeal was whether the respondent's conduct in relation to the principal debtor amounted to a release of the appellant from its obligations under the guarantee. Specifically, the court had to consider whether the respondent's actions constituted a variation of the principal debtor's obligations or a release of the principal debtor, which would, in turn, discharge the guarantor.

The Court of Appeal found that the respondent's actions did not amount to a release of the principal debtor. The court applied the established legal principle that a guarantor is discharged from liability if the creditor, without the guarantor's consent, varies the principal debtor's obligations in a way that prejudices the guarantor, or if the creditor releases the principal debtor from their obligations. However, the court held that the conduct in question did not reach this threshold. The appeal was dismissed.
