Town and country planning – Enforcement notice. The appellant appealed against an order dismissing: (i) his application to quash the decision of the inspector, appointed by the first respondent Secretary of State, to dismiss his appeal against the second respondent local authority's refusal to grant planning permission for the redevelopment of a site; and (ii) his appeal against the inspector's decision to dismiss his appeal against an enforcement notice issued by the authority in respect of the site and to uphold the notice with variations. The Court of Appeal, Civil Division, held, inter alia, that two different versions of a plan had been produced by the appellant and by the authority before the inspector. Extrinsic evidence had plainly been admissible to resolve the factual issue as to which of the two plans had been referred to in the planning permission. As to the enforcement notice, there had been a legally defective variation notice which the authority had had the power to and had withdrawn and corrected before the appeal had been decided by the judge.
