Newtronics Pty Ltd (Receivers and Managers Appointed) (In Liquidation) v Atco Controls Pty Ltd (In Liquidation)

The dispute before the High Court of Australia concerned the priority of a charge held by Atco Controls Pty Ltd (In Liquidation) over certain assets of Newtronics Pty Ltd (Receivers and Managers Appointed) (In Liquidation). Newtronics had granted Atco a charge over "all its present and future book debts and all its present and future choses in action". Subsequently, Newtronics entered into a finance agreement with Commonwealth Bank of Australia (CBA), which also took security over Newtronics' "undertaking, property and assets of every description, both present and future". The core of the dispute was the priority between Atco's charge and CBA's security interest, particularly in relation to certain funds held by Newtronics.

The High Court was required to determine the extent to which Atco's charge over choses in action extended to funds that Newtronics had received from its customers, which were then deposited into a bank account. Specifically, the court had to consider whether these deposited funds constituted choses in action at the time Atco's charge was registered, and if so, whether the charge attached to them in a manner that gave Atco priority over CBA's later, more general security interest. The central legal question revolved around the nature of the chose in action and its transformation upon being paid into a bank account.

Gummow and Crennan JJ held that Atco's charge over choses in action did not extend to the funds once they were paid into Newtronics' bank account. Their Honours reasoned that the chose in action, being a right to receive payment, was extinguished upon payment and replaced by a debt owed by the bank to Newtronics. This debt, being a chose in action, was captured by CBA's later and more comprehensive security interest. The court applied the principle that a charge over a chose in action attaches to the right itself, and when that right is satisfied by payment, the original chose in action ceases to exist. The court further noted that the terms of Atco's charge did not create a floating charge over the company's undertaking or assets generally, but rather a specific charge over identified categories of property.

The High Court allowed the appeal and ordered that the appeal from the Court of Appeal of the Supreme Court of New South Wales be dismissed.
