WESTERN AUSTRALIAN MEAT MARKETING COOPERATIVE LIMITED and VALUER GENERAL

In this case, the Western Australian Meat Marketing Cooperative Limited contested the valuation of a highly specialised property, specifically an abattoir, which was assessed by the Valuer General. The dispute was brought before the Supreme Court of Western Australia, which was tasked with determining the correct method for valuing such a unique property and the appropriate approach to depreciation for the abattoir's improvements. The court had to decide whether the capital value of the property could reasonably be determined using the sales comparison method, and if not, whether the "summation" method, which involves adding the unimproved value to the depreciated replacement cost of the improvements, was appropriate. Additionally, the court needed to determine whether the "straight line" or "reducing balance"/"diminishing value" method of depreciation was more suitable for the improvements on the property.

The court examined the nature of the property and concluded that its highly specialised use as an abattoir made it unsuitable for valuation using the sales comparison method. Instead, the court found the "summation" method to be appropriate for this type of property. The court also deliberated on the depreciation method for the improvements, considering both the "straight line" and "reducing balance"/"diminishing value" methods. Ultimately, the court determined that the "reducing balance"/"diminishing value" method was more appropriate, as it better reflected the decreasing utility of the improvements over time.

Following the court's reasoning, the decision was made that the capital value of the property could not be reasonably determined by the sales comparison method. Instead, the "summation" method, incorporating the unimproved value plus the depreciated replacement cost of the improvements, was deemed suitable. The "reducing balance"/"diminishing value" method of depreciation was also found to be appropriate for the improvements on the property. The court's decision provided clarity on the valuation of highly specialised properties and the appropriate depreciation methods to be applied in such cases.
