Bayliss v Secretary of State for Communities and Local Government & Ors

In a planning challenge, the court must read an inspector’s decision letter as a whole and in a practical, common-sense manner. An inspector need not recite every policy formulaically, provided the reasoning shows that the relevant policy and material considerations were understood and applied. The weight given to material considerations is a matter of planning judgment, subject to rationality. National policy requiring great weight for conserving an Area of Outstanding Natural Beauty does not prescribe the outcome or prevent the decision-maker balancing that factor against the benefits of renewable energy. A challenge based on inadequate reasons or failure to consider evidence will fail where the decision adequately explains the outcome and any alleged error could not have materially affected it.

The claimant challenged, under section 288 of the Town and Country Planning Act 1990, an inspector’s decision allowing an appeal against Purbeck District Council’s refusal of planning permission for four wind turbines and ancillary works near Wareham.

Three grounds alleged that the inspector had: misdirected himself on the weight due to harm to the Dorset Area of Outstanding Natural Beauty; misunderstood or inadequately assessed the development’s wind-resource and electricity-generation benefits; and failed properly to consider turbine safety, including fall-over distance from highways. The central issue was whether the decision letter disclosed a material error of law.

1. Application dismissed. None of the three grounds established a material error of law in the inspector’s decision.
2. Under section 38(6) of the Planning and Compulsory Purchase Act 2004, the development plan must be considered as a whole. There is a presumption in favour of accordance with the plan, but material considerations may rebut it. The weight given to material considerations is for the decision-maker’s planning judgment, subject to rationality. The court determines the correct interpretation of national policy, but intervention requires a material misunderstanding or misapplication.
3. The inspector had found limited harm to a limited part of the AONB. Section 85 of the Countryside and Rights of Way Act 2000 and paragraph 115 of the NPPF required that issue to receive particular weight, but did not require a particular result. Reading the decision letter as a whole, the inspector understood the special status of the AONB. It was unnecessary to repeat the statutory and policy language verbatim.
4. The inspector was entitled to conclude that the renewable-energy benefits were substantial. The parties agreed that the development would generate meaningful renewable electricity and that commercial viability was a matter for the developer, not a land-use consideration. Even using the lower capacity estimate advanced by the objectors, the inspector found that the benefits significantly outweighed the limited harm. His reference to the wind resource in Purbeck and to conditions experienced during the inquiry carried no material weight.
5. The inspector had considered the safety issue, including the Companion Guide’s reference to fall-over distance. The absence of a further substantive discussion did not demonstrate that the issue had been overlooked. The Council and Highway Authority had raised no safety objection, and compliance with post-planning health and safety requirements addressed the identified risk.

The decision letter gave adequate reasons and the claimant suffered no substantial prejudice.
