“(1) Subject to subsection (8) below, subsections (2) to (5) below shall have effect in relation to any notice, order or other document required or authorised by or under any enactment to be given to or served on any person by or on behalf of a local authority or by an officer of a local authority. (2) Any such document may be given to or served on the person in question either by delivering it to him, or by leaving it at his proper address, or by sending it by post to him at that address. … (4) For the purposes of this section … the proper address of any person to or on whom a document is to be given or served shall be his last known address…”
“I would hold that as a general rule, unless there is a statutory requirement to the contrary, in a case in which i) a person (in this case the local planning authority rather than the council taken as a whole) wishes to serve notice relating to a particular property on the owner of that property, and ii) title to that property is registered at HM Land Registry, that person's obligation to make reasonable inquiries goes no further than to search the proprietorship register to ascertain the address of the registered proprietor. It is the responsibility of the registered proprietor to keep his address up to date.”
“…we accept the submissions of Mr Whatley that Ms Tabassam’s default in failing to keep her address details up to date with the Land Registry cannot amount to a ‘reasonable excuse’. To find otherwise would be for the Applicant to rely upon her own failures to avoid culpability.”
“82. One situation that can sometimes cause difficulties is when the taxpayer’s asserted reasonable excuse is purely that he/she did not know of the particular requirement that has been shown to have been breached. It is a much-cited aphorism that “ignorance of the law is no excuse”, and on occasion this has been given as a reason why the defence of reasonable excuse cannot be available in such circumstances. We see no basis for this argument. Some requirements of the law are well-known, simple and straightforward but others are much less so. It will be a matter of judgment for the FTT in each case whether it was objectively reasonable for the particular taxpayer, in the circumstances of the case, to have been ignorant of the requirement in question, and for how long.”
