The idea is important because the decision making on planning matters should be taken locally wherever possible. It would also reduce costs because local Councils have to bear the cost of the Inspectorate.
The activities of the Planning Inspectorate need curtailing. If a planning application is turned down, an appeal can be launched by the aggrieved party. However, the Inspectorate appoints someone who knows nothing about the area and his/her opinion takes precedence of that of the local planning authority. Even though the Inspectorate employs someone to do quality control of its decisions, it appears not to carry out any quality control. I know of a case when the Inspectorate was asked to review a decision it had made, the quality control man sid they could not do this because they had thrown away the papers!
