When an LPA senior planning officer on behalf of the authority issues a written (email) meaningful start notice to an applicant and agent. Can that applicant be told by the same senior LPA officer much later that a mistake by the LPA officer had been made and the 'meaningful start' written notice no longer applies. Furthermore to receive a 'meaningful start' approval again some 'reserved matters' requirements must be completed. Note: the applicant was not considered to be at fault whatsoever & he is informed that a meaningful start means the same as a lawful start. Is there case law on this matter.
