Estate of the Late Clare Mahon v Chief Executive, Department of Main Roads

The case involves a claim for compensation under the Acquisition of Land Act 1967, where the Estate of the late Clare Mahon, represented by Helen Denise Higgs and Brenda Mary Burke, seek compensation for the acquisition of certain lands by the Department of Main Roads. The disputed lands consist of four lots, totaling approximately 28.6 hectares, located in Gowrie Junction, Queensland. The claimants assert that the lands are suitable for rural homesite development and have been valued at a total of $468,000.

The court was tasked with determining the appropriate compensation for the acquired lands, specifically focusing on the market value of the properties in question. The key legal issue was the valuation of the land, considering the specific characteristics and circumstances surrounding each lot, as well as the limited number of comparable sales in the area. The court had to weigh expert evidence from both parties and decide on the most reliable and relevant data to ascertain the market value.

In delivering the judgment, the court found that while the claimants' expert provided a detailed analysis of the limited comparable sales, it did not adequately consider the impact of the nearby waste water treatment works and tannery on property values in the area. Conversely, the court accepted that the expert for the Department of Main Roads, while acknowledging the adverse effects of the treatment works, failed to appropriately account for the removal of those effects by mid-1997. The court concluded that the most reliable evidence came from the resale of two lots, which indicated an increase in the market value between 1995 and 1996. Based on this, the court awarded compensation to the claimants.

The final order of the court was that the Estate of the late Clare Mahon is to be paid compensation in the amount of $468,000 for the acquisition of the specified lands.
