Roxborough v Rothmans of Pall Mall Australia Ltd

The case of *Roxborough v Rothmans of Pall Mall Australia Ltd* involved a dispute between retailers (appellants) and a wholesaler, Rothmans (respondent). The retailers sought the repayment of money paid to Rothmans, which represented a tobacco licence fee that had been declared invalid. The wholesale cost of goods included this fee, and the retailers argued that because the fee was invalid, there had been a total failure of consideration for that portion of the payment, entitling them to recover the money. The matter was heard by the High Court of Australia.

The central legal issues before the High Court were whether the invalidity of the tobacco licence fee constituted a failure of a distinct and severable part of the consideration paid by the retailers, and consequently, whether Rothmans held the money received for the fee to the use of the retailers. The court also considered whether the retailers had suffered a loss that could be recovered, particularly in light of the fact that they had passed the cost of the invalid tax onto consumers, who were unlikely to claim it back. This raised questions about unjust enrichment and whether the enrichment must be directly at the expense of the party seeking recovery.

The High Court reasoned that the tobacco licence fee, although part of the overall wholesale price, was a distinct and severable component of the consideration. The invalidity of the fee meant that the purpose for which that specific part of the payment was made had failed. The court applied the principle that where a contract includes a payment for a specific purpose, and that purpose fails due to illegality or invalidity, the money paid for that purpose is recoverable under the action for money had and received, even if other parts of the contract remain valid. The court found that Rothmans had received the money for the invalid licence fee under circumstances where it was not entitled to retain it, and that the retailers had a right to recover it.

The High Court allowed the appeal, setting aside the orders of the Federal Court. It ordered that judgment be entered for each of the appellant retailers for specific sums representing the amounts paid for the invalid licence fee, and that Rothmans pay the appellants' costs of the action.
