Events subsequent to planning decision cannot invalidate that decision (Wiltshire Council v SSHCLG)
Planning analysis: In Wiltshire Council v SSHCLG, the Planning Court dismissed a claim for statutory review of a decision granting planning permission for the redevelopment of an historic airfield, holding that a subsequent event cannot retrospectively render a lawful planning decision unlawful, even where that event materially affects the factual basis upon which the decision was reached. In this case, a fire occurred days after the decision to grant planning permission, destroying a listed building, the restoration of which was a key part of the planning case in favour of allowing the development.
