Acoustic and Felts Pty Ltd v Misthos

Acoustic and Felts Pty Ltd appealed to the New South Wales Court of Appeal against a decision of the Supreme Court of New South Wales. The dispute concerned the enforceability of a guarantee provided by the respondents in favour of the appellant.

The primary legal issue before the Court of Appeal was whether the respondents were discharged from their obligations under the guarantee due to the appellant's conduct. Specifically, the court had to determine if the appellant had, by its actions or omissions, prejudiced the respondents' position as guarantors, thereby releasing them from their liability.

The Court of Appeal considered the principles of equity relating to guarantees, particularly the duty of a creditor to a surety. The court found that the appellant had not acted in a way that fundamentally altered the nature of the principal debtor's obligations or prejudiced the respondents' rights of subrogation. The appellant's conduct was found not to have discharged the respondents from their liability under the guarantee. The appeal was dismissed.
