Commonwealth v Arklay

The plaintiff, Phyllis Joy Arklay, commenced an action in the High Court of Australia against the defendant, the Commonwealth of Australia, seeking compensation for the compulsory acquisition of her land. The dispute concerned the amount of compensation payable for the land and improvements, with the plaintiff claiming a higher sum than the defendant was prepared to offer.

The central legal issue before the court was how to determine the "value" of land for compensation purposes under the *Lands Acquisition Act 1906-1936* when the acquisition occurred during a period of land sales control. Specifically, the court had to decide whether the compensation should be limited to the price permitted by government controls, or if it could include an amount reflecting the potential for a higher price in a free market after controls were lifted.

The court reasoned that while the *Lands Acquisition Act* requires compensation to be assessed according to the value of the land at a specific date, this value must be determined in a manner that provides "just terms" as mandated by the Constitution. In a period of land sales control, the hypothetical price a willing but not anxious seller would accept from a willing purchaser must account for the fact that controls might eventually be lifted. Therefore, the valuation should consider not only the controlled price but also an amount representing the anticipated increase in value once controls cease. The court affirmed the decision of Webb J., finding that the plaintiff was entitled to compensation that included this "retention value" or potential future enhanced price, in addition to the controlled price.

The Full Court dismissed the appeal, upholding the trial judge's assessment of compensation. The court found that the trial judge had correctly applied the principles of valuation under the *Lands Acquisition Act*, particularly in considering the potential for enhanced value after the cessation of land sales controls. The compensation awarded to the plaintiff was £3,800, representing the outstanding amount after an initial payment.
