WATTLEUP ROAD DEVELOPMENT COMPANY PTY LTD and WESTERN AUSTRALIAN PLANNING COMMISSION

The case before the court involved Wattleup Road Development Company Pty Ltd and the Western Australian Planning Commission. The dispute centred on the approval of two residential subdivisions. The company sought approval, while the Commission recommended refusal. The matter was ultimately determined by the Supreme Court of Western Australia.

The central legal issue was whether the proposed subdivisions were acceptable in relation to the health and amenity impacts of dust. This involved assessing the adequacy of air quality monitoring, the averaging of monitoring results, and the potential for shorter-term amenity impacts. The court also considered whether the evidence demonstrated that the proposed subdivisions would be acceptable in relation to dust in future years, taking into account climatic conditions and the potential impact of climate change. Additionally, the court examined whether the developments would affect the industrial amenity of the residue disposal area and the consistency with the planning framework.

In its reasoning, the court found that the proposed subdivisions would result in unacceptable health and amenity impacts due to dust. The air quality monitoring was deemed inadequate, and the averaging of results over 24 hours did not adequately address potential shorter-term impacts. The court concluded that the evidence did not demonstrate the subdivisions would be acceptable in relation to future dust impacts. The court also found that the developments would affect the industrial amenity of the residue disposal area and were not consistent with the planning framework. The court ultimately upheld the tribunal's recommendation to refuse approval for both proposed subdivisions.

The final orders of the court were to affirm the tribunal's recommendation to the Hon Minister for Planning to refuse approval for the proposed subdivisions.
