Mount Lawley Pty Ltd v Western Australian Planning Commission

Mount Lawley Pty Ltd sought to challenge a decision by the Western Australian Planning Commission to resume land for town planning purposes. The company argued that the resumption would significantly impact its ability to use the land for its intended purposes. The case was heard in the Supreme Court of Western Australia. The primary legal issues for the court to determine were the relevance of the effect of the resumption on the landowner's use of the land and the reasonableness of the parties' conduct during the litigation, particularly in relation to the acceptance or rejection of a Calderbank offer.

The court considered that the landowner's ability to use the land was a crucial factor in assessing the impact of the resumption. However, it held that the proximity of either party to the judgment value was not determinative of the success in litigation. Regarding the Calderbank offer, the court found that it was not reasonable for the plaintiff to reject the offer, as it would have resulted in a substantial saving of costs for both parties. The court held that the plaintiff's conduct in rejecting the offer was unreasonable and a significant factor in awarding costs against the plaintiff.

In light of the above, the court ordered that the plaintiff pay the defendant's costs of the trial and re-trial. This decision highlights the importance of considering the impact of town planning decisions on landowners and the potential consequences of unreasonable conduct during litigation. The court's emphasis on the relevance of the effect of the resumption on the landowner's use of the land and the reasonableness of the parties' conduct during the litigation provides valuable guidance for future cases involving similar issues.
