Associated Alloys Pty Ltd v Metropolitan Engineering and Anor

In *Associated Alloys Pty Ltd v Metropolitan Engineering and Anor*, the High Court of Australia considered a dispute concerning the enforceability of a guarantee. Associated Alloys Pty Ltd (the appellant) sought to enforce a guarantee provided by Metropolitan Engineering and Anor (the respondents) in favour of a company called Metal Manufacturers Ltd. The guarantee was in respect of debts owed by a third party, Metal Manufacturers Pty Ltd, to Metal Manufacturers Ltd.

The central legal issue before the High Court was whether the guarantee, which was expressed to be for the benefit of "Metal Manufacturers Ltd", could be enforced by Associated Alloys Pty Ltd, which had acquired the rights of Metal Manufacturers Ltd. The respondents argued that the guarantee was personal to Metal Manufacturers Ltd and not assignable.

The High Court held that the guarantee was a contractual right that was assignable. The Court reasoned that the language of the guarantee did not indicate an intention that the benefit of the guarantee should be non-assignable. The Court applied the general principle that contractual rights are assignable unless there is a contrary intention expressed or implied in the contract, or if the assignment would be of a purely personal nature. The Court found that the assignment of the debt and the associated security, including the guarantee, was a commercial transaction and not personal in nature.

The High Court therefore found in favour of Associated Alloys Pty Ltd, holding that it was entitled to enforce the guarantee.
