Shrimpton v The Commonwealth

The plaintiff, Mary Frances Shrimpton, sought declarations from the High Court of Australia regarding the validity of Part III of the National Security (Economic Organization) Regulations and the conditions imposed by the Treasurer on her proposed purchase of land. The plaintiff had agreed to purchase land for £575, with the contract being subject to the Treasurer's consent as required by the Regulations. The Treasurer indicated consent would be granted if the purchase price was paid in cash without borrowing and if the plaintiff deposited Commonwealth securities valued at £350 with her bank, subject to specific terms regarding the holding of these securities.

The legal issues before the Court were twofold: first, whether Part III of the National Security (Economic Organization) Regulations, as they related to the sale or purchase of land, were authorised by the Constitution or the National Security Act 1939-1943, and thus valid; and second, if the Regulations were valid, whether the Treasurer was empowered to impose the conditions he had stipulated, specifically the deposit of Commonwealth securities, as a prerequisite for granting consent to the land purchase.

A majority of the Court, comprising Latham C.J., Starke, Dixon, and McTiernan JJ., held that the condition requiring the deposit of Commonwealth securities went beyond the purpose for which the discretion was conferred upon the Treasurer and was therefore not authorised by the Regulations. Latham C.J. and McTiernan J. were of the opinion that the Regulations themselves were valid, while Rich and Williams JJ. found Part III of the Regulations, concerning land transactions, to be invalid as it was not authorised by the Constitution or the National Security Act. Dixon J. was not prepared to state that the control over land dealings established by the Regulations was beyond the defence power.

The Court ordered that the plaintiff was entitled to a declaration that the Treasurer was not empowered to require compliance with the condition relating to the deposit of Commonwealth securities.
