  • Access to justice: protective costs orders in planning challenges

    Third parties and competing developers have no rights of appeal to the Secretary of State against planning decisions. Disappointed applicants can appeal to the Secretary of State and can have the merits of the application reconsidered. The only remedy available to a disappointed third party is a challenge by way of judicial review in the High Court on a point of law. The sense of frustration and disempowerment this creates has not been helped by the increasing complexity of the planning process and the use of consultation to legitimise decisions that many perceive may already have been taken.
