Sparrow v Chief Executive, Department of Natural Resources and Water

Sparrow and the Chief Executive of the Department of Natural Resources and Water appeared before the court in a valuation dispute. The case revolved around the unimproved value of certain grazing land, specifically the classification and assessment of brigalow scrub areas. The applicant sought to challenge the valuation of the land, arguing that the valuation process was flawed and that the unimproved capital value was incorrectly determined.

The primary legal issues before the court were whether the expert witness should have acted more as an advocate than an impartial expert, and the appropriate means of assessing the unimproved value of the land, specifically in relation to the brigalow scrub areas. The court needed to determine whether the use of satellite imagery and aerial photographs was an acceptable method for assessing such areas.

The court found that the expert witness had indeed overstepped the bounds of impartiality and had acted more as an advocate. This influenced the reliability of their valuation. Regarding the assessment of the brigalow scrub areas, the court held that the use of satellite imagery and aerial photographs was an acceptable method, provided it was conducted correctly and with due consideration. The court determined that the unimproved capital value of the land should be recalculated. Consequently, the appeal was allowed, and the unimproved capital value was determined at Six Hundred and Thirty-Five Thousand Dollars ($635,000).
