McKay v Commissioner of Main Roads [No 7]

The matter before the court involved McKay, the appellant, who sought to challenge the valuation of land acquired by the Commissioner of Main Roads under the Land Administration Act 1997 (WA). The dispute centred on the valuation of land which had been acquired for public works, and the method used to determine its market value. Specifically, McKay argued that the valuation process had not appropriately considered the land's potential for urban development in the absence of the proposed public works.

The key legal issues before the court were whether the statutory requirement to discount the land's value for the proposed public works permitted an enquiry into the zoning of the land in the absence of those works, and the extent to which evidence of planning instruments and other matters after the date of taking could be used to assess the land's market value. Additionally, the court had to consider the appropriate valuation methodology, including the use of comparable sales and hypothetical subdivision analysis.

In its decision, the court found that the statutory requirement to discount the land's value for the proposed public works did not permit an enquiry into the zoning of the land in the absence of those works. The court held that such an enquiry would be inconsistent with the purpose of the legislation, which was to ensure that compensation was not inflated by the value attributable to the proposed public works. The court also held that evidence of planning instruments and other matters after the date of taking could be used to confirm a foresight of the land's market value, but only to the extent that it was relevant to the market value of the land at the date of taking. Finally, the court found that the Commissioner had appropriately used comparable sales and hypothetical subdivision analysis to value the land, and that the valuation was not excessive.

As a result of the court's decision, the appeal was dismissed and the valuation of the land was upheld. The court found that the Commissioner had appropriately exercised his discretion under the Act in determining the market value of the land, and that the valuation was not excessive.
