Mount Lawley Pty Ltd v Western Australian Planning Commission

Mount Lawley Pty Ltd v Western Australian Planning Commission involved a dispute concerning the value of land reserved and acquired under the Metropolitan Region Town Planning Scheme Act 1959 (WA). The primary legal issues were the valuation process for land acquisition, the impact of the planning scheme on land value, and the validity of the election to acquire land by the Western Australian Planning Commission. The court had to determine whether the value of the land should be assessed without regard to the planning scheme attributes and whether the omission in the notice of election could be remedied. Additionally, the court examined the concept of special value in the valuation process, the inclusion of development application costs and interest in the purchase price, and the claim for injurious affection.

The court's reasoning focused on the proper assessment of land value under s 36 of the Metropolitan Region Town Planning Scheme Act 1959 (WA). It held that the value of land should be assessed without regard to the planning scheme attributes but must consider events leading to the reservation and the attributes of the land. The court also emphasised that valuations should not be influenced by the exigencies of litigation and that the market value should include costs of development application, holding the land until settlement, and acquiring replacement property. Regarding the election to acquire land, the court ruled that an omission in the notice could be remedied by a later notice, even after the time fixed by s 36(2)(b) of the Act, under s 55 of the Interpretation Act 1984 (WA). The court further clarified that the claim for injurious affection could proceed in the absence of a development application.

Due to the extensive, complex, and controversial nature of the evidence, the court had to carefully review the findings of fact, considering the lengthy delay in giving judgment. It noted that while the trial judge had the advantage of seeing and hearing the witnesses, the significant delay weakened this advantage. The court's decision underscored the importance of timely judgments and adequate reasons to maintain public confidence in the judicial process. The final orders addressed the valuation of the land, the validity of the election to acquire, and the claim for injurious affection, providing clarity on these critical issues in the context of town planning and land acquisition.
