76.This section inserts a new section 33A in the 1997 Act. This gives the planning authority the power to issue a notice requiring the owner of the land where planning permission has not been granted but development has already been carried out to make an application for planning permission. The existing section 33 of the 1997 Act only provides that planning permission for development already carried out may be granted. Issuing the notice constitutes enforcement action under section 123(2) of the 1997 Act.
