Thomas v National Australia Bank Ltd

The case of Thomas v National Australia Bank Ltd involved a dispute between the plaintiff, Graham Arnold Prance Thomas, and several defendants, including National Australia Bank Limited, Lloyd Bank NZA Limited, Arthur Andersen, and John Ebbage. The plaintiff, who had been declared bankrupt, sought to assign his rights of action to his trustee in bankruptcy, who then assigned them back to the plaintiff. The plaintiff subsequently initiated legal proceedings against the defendants, but had not given them notice of the assignment prior to commencing the action. The defendants argued that the plaintiff's failure to provide notice rendered the action invalid.

The central legal issue before the court was whether the plaintiff was entitled to bring and maintain the action without having given the defendants prior notice of the assignment. The court had to determine if the requirement of notice to the defendants was necessary for the plaintiff to validly enforce the assigned causes of action against them. The court considered the relevant authorities on equitable assignments, including the New Zealand Court of Appeal decision in Mountain Road (No. 9) Ltd v. Michael Edgley Corporation Pty Ltd, which held that notice to the debtor is necessary for an equitable assignee to enforce the chose in action against that person.

The court concluded that the authorities supported the requirement of notice to the debtor for an equitable assignment to be effective against the debtor. The court found that the plaintiff's failure to give notice to the defendants prior to commencing the action rendered the action invalid. The court dismissed the action as against the first, third, and fourth defendants, and ordered the plaintiff to pay those defendants' costs.

This decision underscores the importance of providing notice to the debtor of an assignment to validate the assignee's right to enforce the chose in action against the debtor, even in the context of an equitable assignment. The failure to provide such notice prior to bringing proceedings can render the action invalid, as it did in this case.
