R (On the Application of I’m Your Man Ltd.) v North Somerset Council  EWHC 342Planning permission had been obtained for the erection of a helicopter museum. Some time after it opened it began to increase the number of helicopter flights at the site. M sought judicial review of the planning authority’s decision not to take enforcement action against the museum. The court held that helicopter flights are an incidental purpose to the running of a helicopter museum and therefore covered by the planning permission. However, the planning authority should continue to monitor the number of flights at the site.
