Town and country planning – Permission for development. The claimant bus and coach company sought judicial review of the defendant local planning authority's decision to serve a breach of condition notice, alleging a failure to comply with a condition of the planning permission, requiring that no repairs or maintenance of vehicles, or other industrial or commercial activities take place outside specified hours. The Administrative Court, in dismissing the application, held that the words 'industrial or commercial activities' included the activity of starting a bus or coach in readiness for its departure from the depot and that the authority had been aware that buses and coaches had a 'warm up' time.
