Hi all, my first post on E-Goat! Only applicants can appeal against a planning decision. Town and Country Planning Act 1990. Central Government can only intervene in certain exceptional circumstances, not applicable in this case, nor would Central Government wish to intervene in this case. The only route available to aggrieved objectors would be to seek Judicial Review of the decision, essentially on the grounds that the planning authority have not acted lawfully in some part of the decision-making process. In the rare event of a successful Judicial Review, the Court quashes the planning decision but does not decide the planning issue itself; the planning authority must consider the application afresh and may again decide to approve.
Not a technical legal answer, but I hope that helps to explain.
