Castletown Estates Ltd., Carmarthenshire County Council v. Welsh Ministers

Claimants challenged the decision by the Welsh Ministers to refuse to grant a planning permit for a mixed-use redevelopment, alleging that the Ministers used inaccurate flood and development advice maps to assess the risk of flooding. At issue was the precautionary approach employed by the Minister to take into account climate change to assess future flood risks. The court found that the Minister’s determination that there were impermissible flood risks at the site was fair and reasonable. The application for appeal was dismissed.
