Town and country planning – Conservation. The proceedings concerned a challenge to a policy contained in the Wealden District (incorporating part of the South Downs National Park) Core Strategy Local Plan, which provided, inter alia, that, for new development within 7km of Ashdown Forest, suitable alternative natural green space was to be provided. The claimant's claim seeking to quash the core strategy in whole or in part was dismissed. The Court of Appeal, Civil Division, in allowing the claimant's appeal, held that the policy, in so far as it related to the 7km zone, had been adopted in breach of the duty, under reg 12 of the Environmental Assessment of Plans and Programmes Regulations 2004, SI 2004/1633, relating to the assessment of reasonable alternatives.
