“The Court of Appeal allowed their appeals and the planning authorities appealed to the House of Lords. All the appeals were dismissed. The House of Lords held that section 187B of the 1990 Act conferred on the court an original and discretionary, not a supervisory, jurisdiction, to be exercised with due regard to the purpose for which it was conferred, to restrain actual or threatened breaches of planning control; that it was inherent in the injunctive remedy that its grant depended on the court’s judgment of all the circumstances of the case; that, although the court would not examine matters of planning policy and judgment which lay within the exclusive purview of the authorities responsible for administering the planning regime, the court was not obliged to grant relief because a planning authority considered it necessary or expedient to restrain a planning breach; that the court would have regard to all, including the personal, circumstances of the case, and, since section 6 of the 1998 Act required the court to act compatibly with a Convention right (as so defined), and having regard to the right guaranteed in article 8, the court would only grant an injunction where it was just and proportionate to do so; and that, accordingly, the planning authorities’ application should be determined on that basis.”
“The effect of the various speeches – set out most comprehensively in the leading speech of Lord Bingham of Cornhill, was as follows: 1) section 187B confers on the courts an original and discretionary, not a supervisory, jurisdiction, so that a defendant seeking to resist injunctive relief is not restricted to judicial review grounds; 2) it is questionable whether Article 8 adds anything to the existing equitable duty of a court in the exercise of its discretion under section 187B; 3) the jurisdiction is to be exercised with due regard to the purpose for which was conferred, namely to restrain breaches of planning control, and flagrant and prolonged defiance by a defendant of the relevant planning controls and procedures may weigh heavily in favour of injunctive relief; 4) however, it is inherent in the injunctive remedy that its grant depends on a court’s judgment of all the circumstances of the case; 5) although a court would not examine matters of planning policy and judgment, since those lay within the exclusive purview of the responsible local planning authority, it will consider whether and the extent to which, the local planning authority has taken account of the personal circumstances of the defendant and any hardship that injunctive relief might cause, and it is not obliged to grant relief simply because a planning authority considered it necessary or expedient to restrain a planning breach; 6) having had regard to all the circumstances of the case, the court will only grant an injunction where it is just and proportionate to do so, taking account, inter alia, of the rights of the person or persons against whom injunctive relief is sought, and of whether it is relief with which that person or persons can and reasonably ought to comply. Thus Lord Bingham’s reasoning, and that of the other Law Lords, in endorsing Simon Brown LJ’s analysis of the balance to be sought between public and private interest in such cases, was to recognise two stages before, or certainly by the time, injunctive relief is sought: first, to look at the planning merits of the matter, and, in doing so, to accord respect to the local planning authority’s conclusions; and second to consider for itself, in the light of the planning merits and any other circumstances, in particular, those of the defendant, whether to grant injunctive relief.”
