Gillen v Laffer

The case of *Gillen v Laffer* concerned an appeal from the Supreme Court of South Australia to the High Court of Australia. The dispute arose from an agreement for the sale of land between the Minister of Repatriation for South Australia and the appellant, Mr. Gillen, under which the purchase price was to be paid by instalments. The appellant was ejected from the land, and the respondent, Mr. Laffer, who was the Commissioner of Crown Lands and Minister for Repatriation, sought to justify this action by asserting the agreement had been lawfully cancelled or determined.

The High Court was required to determine several legal issues. Firstly, whether a notice issued by the respondent was a sufficient demand for payment to justify cancellation of the agreement for non-payment of instalments, as stipulated in clause 24 of the agreement. Secondly, whether the agreement could be lawfully determined by the respondent under clause 22, which allowed for cancellation due to the purchaser's incompetency or neglect, without affording the appellant an opportunity to be heard. Finally, the Court considered the effect of registering a forfeiture or determination of a Crown lease under section 94 of the *Real Property Act 1886* (SA).

The Court held that the notice demanding payment was ineffective to support the cancellation of the agreement. Knox C.J. and Higgins J. found that the notice lacked an explicit demand for payment, while Starke J. concluded it was not issued by the correct party, the Minister of Repatriation. Regarding the determination of the agreement under clause 22, Knox C.J., Rich J., and Starke J. (with Higgins J. dissenting) determined that the clause could not be acted upon without providing the appellant an opportunity to be heard and respond to any allegations against him. The Court also affirmed that section 94 of the *Real Property Act 1886* (SA) presupposes a lawful forfeiture or determination and does not validate an unlawful one.

Consequently, the High Court allowed the appeal, reversing the decision of the Supreme Court of South Australia. The Court found that the respondent had failed to establish any lawful grounds for the cancellation or determination of the agreement, and therefore, the ejection of the appellant was unjustified.
