Cachia v Walker

In *Cachia v Walker*, the New South Wales Court of Appeal considered a dispute between the appellant, Mr Cachia, and the respondent, Mr Walker, concerning the enforceability of a guarantee. The central issue revolved around whether Mr Walker, as the guarantor, was bound by the terms of a guarantee he had signed, despite certain alleged misrepresentations made by Mr Cachia.

The Court was required to determine whether Mr Walker was estopped from denying liability under the guarantee. Specifically, the court had to consider whether Mr Walker's conduct, in signing the guarantee and subsequently making payments under it, amounted to a representation that he intended to be bound by its terms, and whether Mr Cachia relied on this representation to his detriment. The question of whether any alleged misrepresentations by Mr Cachia vitiated the guarantee was also a key consideration.

The Court of Appeal found that Mr Walker was indeed estopped from denying liability. It reasoned that by signing the guarantee and making payments, Mr Walker had represented to Mr Cachia that he intended to be bound by the guarantee. Mr Cachia had relied on this representation by continuing to advance funds. The Court held that the principles of estoppel applied, preventing Mr Walker from later asserting that he was not bound by the guarantee, even if there had been some misrepresentation. The Court distinguished this situation from cases where a party is induced to sign a document under a fundamental misapprehension as to its nature.

Consequently, the Court of Appeal dismissed Mr Cachia's appeal, upholding the primary judge's finding that Mr Walker was liable under the guarantee.
