“The extraction of gravel shall cease on or before30th September 2000 . All restoration operations, including the removal of all plant, buildings, hardstandings and access roads, but excluding after-care and drainage, shall be completed by30th September 2001 .”
“(2) An old mining permission shall, if an application under [Schedule 2] to determine the conditions to which the permission is to be subject is finally determined, have effect as from the formal determination as if granted on the terms required to be registered. (3) If no such development has, at any time in the period of two years ending with May 1, 1991, been carried out to any substantial extent anywhere in, on or under the land to which an old mining permission relates, that permission shall not authorise any such development to be carried out at any time after the coming into force of this section unless – (a) the permission has effect in accordance with subsection (2) above; and (b) the development is carried out after such an application is finally determined.”
“Where an application to determine the conditions to which an old mining permission is to be subject is finally determined, the conditions must be entered in the appropriate part of [the] register.”
“I accept that the court has a discretion under section 288. It is not bound to quash a decision even if it concludes that there has been some error of law. The error of law in the present case went to the heart of the decision. Condition 1 was the only condition in dispute. It was vital that its invalidity was acknowledged as the correct starting point for any decision. In some cases the error of law may have become of academic interest, by reason, for example, of the passage of time. That is not the position here. As [Counsel] correctly submitted, this is an issue that will not go away. The validity of Condition 1 can be raised if the development commences and enforcement proceedings are begun, or if there is a prosecution for failure to comply with a breach of condition notice. It can be raised in the context of an application for a certificate under section 192 of the 1990 Act, or in proceedings for declaratory relief. In the light of these potential challenges, it seems eminently sensible to resolve the matter in the context of this decision letter.”
“Under general planning law invalid conditions may be challenged by a number of means: (1) In an appeal under section 174 against an enforcement notice alleging a breach of condition (see eg Tarmac Heavy Building Materials UK Ltd v Secretary of State(2000) 79 P&CR 260 , 267-8; (2) As a defence to a prosecution for failing to comply with a breach of condition notice ( Dilieto v Ealing LBC[2000] QB 381 ; Davenport v Hammersmith and Fulham LBC(1999) 78 P&CR 421 ; (3) By an application under section 192 of TCPA 1990 for a certificate as to the lawfulness of proposed operations; (4) Proceedings in the High Court seeking a declaration that condition 1 is invalid and that the 1946 permission will last until 2042 ( Hall & Co Ltd v Shoreham UDC[1964] 1 WLR 240 ; Mouchel Superannuation Fund Trustees v Oxfordshire CC[1992] 1 PLR 97 ). Such well-established authorities have not been overruled by the comments of Lord Hoffmann in R v East Sussex CC ex parte Reprotech (Pebsham) Ltd[2002] UKHL 8 ,[2002] 4 All ER 58 .”
