Mike I am concerned that it might appear to others that this is a private discussion between you and me, but I thank you for your contributions so far and please do continue to reply. The law states and makes clear (and I cannot quote individual sections off the top of my head) that enforcement action may not be taken after 10 years has expired. This is an instruction, not an option. Thus any notice, whether it is a planning EN or other notice regarding an entirely different matter (oranges or rhubarb) that is issued which is prohibited in law is plainly invalid. So how is it that an EN issued after 10+ years has expired can be deemed to be a) legal, and b) legally served? Let us say a police officer issues me with a ticket for a road traffic offence that was repealed several years ago. The fact that he has issued the ticket does not make it legal and legally served. Similarly, I may have a bundle of white fivers. They say £5 on their face, but they have no legal worth whatsoever. As it happens they are of interest to note collectors and have a value in that sense. I hold that the service of a notice served out of time does not make that notice legal and enforceable. Also in my view an appeal against such a notice is irrelevant because in law the appellant is appealing against null. Am I missing something? Have I got something wrong? Have I misinterpreted the clear wording of the Act? Or am I simply stupid? It remains an option to appeal against the refusal of LDC on the grounds that the EN was and is invalid as it was served out of time. Or leave things as they are and wait for the LPA to take further enforcement action. I shall also write to the EO in question (as I understand this is now being handed back from planning to enforcement) requesting that the EN is cancelled/withdrawn and struck form the regsister. I'm sorry. I have said I cannot quote individual sections off the top of my head, and I'm in a bit of a rush right now (see typos), but what is a section D / ground D appeal. Have I already covered it? I'll have to take some time to re-read the legislation and note individual sections. As regards my request for the withdrawal of the EN, the PO said they couldn't do that - they were unable to do that. I feel that though there is over 10 years continuous use, and that can be proved, the LPA just don't want it there! I would finally add that I was initially recruited simply to put together the application - the paperwork. The applican't solicitor was sorting out the witness statements, and should have advised the applicant more fully. The statements had a myriad of mistakes and i put together a series of corrective documents, but finally I advised the applicant to stop ans start all over again with a fresh application. The appricant preferred to continue as was and this contributed to the failure and refusal of the first LDC. The applicant then asked me to sort out the appeal, which after the advice I have previously outlined, we asked to be held in abeyance in favour of a fresh application for a LDC. When is was made clear that the LDC would be refused because of the existence of the EN, I carried out my own investigation of the law and procedures. As stated previously, I am a retired professional with a good deal of property experience, but no specialistation in planning law. Looking back on my previous experience and knowledge, I cannot see how the EN can be enforced in a court of law. JJ
