Mercer v Western Australian Planning Commission

The matter involved the applicant, Mercer, who sought compensation for land that had been resumed by the Western Australian Planning Commission. The parties contested the valuation of the land and the appropriate methodology for determining its value. The case was heard in the Supreme Court of Western Australia.

The central legal issues before the court were the correct valuation of the resumed land and the appropriate methodology to be applied in determining this valuation. Mercer argued for a higher valuation, while the Commission contended that the valuation provided by their expert witness was accurate. The court had to consider the evidence presented by both parties and determine the appropriate compensation for the resumption of the land.

In delivering the judgment, the court held that the valuation provided by Mercer's expert witness was more reliable and accurate than that provided by the Commission's expert. The court found that the Commission's expert had not taken into account certain relevant factors, such as the potential for future development of the land, in their valuation. The court also found that the Commission's expert had placed undue weight on certain evidence that was not relevant to the valuation of the land. Based on this reasoning, the court awarded compensation of $2,264,625 plus interest, in favour of Mercer.

The final orders of the court were that compensation in the sum of $2,264,625 plus interest be paid to Mercer by the Western Australian Planning Commission.
