"By virtue of subs. (9) the notice must specify a compliance period, which commences on the date the notice takes effect, for the carrying out of any required steps or the cessation of any specified activities." [31] In my view, that correctly states the position. 13. Harrison J concluded that the compliance period specified should start from the date which the notice takes effect: see [34]. 14. The compliance period incorporated by the notice of variation runs from4 May 2012 . It is plain beyond argument that this is a date before the notice takes effect, because the effect of the present appeal under s 289 TCPA 1990 is to suspend the effect of the enforcement notice. Accordingly, the enforcement notice as varied fails to specify a compliance period which commences on the date which the notice takes effect, and accordingly the enforcement notice fails to comply with s 173(9) TCPA 1990. 15. By way of practical illustration of the fact that the period given by the IP in the varied notice is invalid, it is instructive to consider the position should the appeal under s 289 succeed. The matter would then be remitted to the Secretary of State, the appeal still undetermined, but the notice may fall to be complied with before that appeal has been determined and the notice has taken effect. That position would be nonsensical. This confirms that the approach in Lynes is good law and of direct applicability to the present case. 16. The consequences of such a failure were considered in Lynes. Harrison J, relying on the leading authority of Miller-Mead v Minister of Housing and Local Government[1963] 2 QB 196 concluded that the failure to specify a period for compliance in accordance with s 173(9) rendered the notice a nullity: [48] Having considered the submissions of both parties and the authorities to which I have been referred, I have reached the conclusion that an enforcement notice which, on the face of it and without having to refer to evidence elsewhere, fails to specify a period for compliance as required by section 173(9) is a nullity and it is therefore without legal effect. That being so, it cannot be the subject of amendment by the Secretary of State under section 176. The power of amendment under section 176 cannot relate to an enforcement notice that is a nullity. The test of whether an amendment to an enforcement notice can be made without injustice can only apply to a notice which is not a nullity. Furthermore, an enforcement notice that is a nullity cannot be made the subject of an appeal under section 174(2)(g). It is relevant to note that section 174(2)(g) is predicated on the basis that a period for compliance has been specified in the notice, whereas no such period has been specified in these enforcement notices. [49] I am very conscious of the need to avoid technicalities and artificial distinctions when dealing with enforcement notices, but the failure to comply with a basic statutory provision for a valid enforcement notice, such as specification of a period for compliance, cannot be said to be a technicality. An enforcement notice which, on its face, does not comply with such a requirement, is a nullity and therefore incapable of amendment. As it cannot be the subject of an appeal under section 174, the preclusive provisions of section 285 do not apply and the claimants are entitled to apply for judicial review for the declaration that they seek. 17. For those reasons, it is respectfully submitted that the effect of the notice of variation is to render the enforcement notice a nullity. If it has no legal effect, it cannot properly be the subject of an appeal under s 174 TCPA 1990 or subsequently s 285 TCPA 1990. Accordingly, the Appellant submits that the Court should declare the enforcement notice to be a nullity and formally dismiss the appeal under s 289 TCPA 1990. The Appellant will seek the costs of pursuing that appeal from the IP. [30] ...I do not think that the statutory framework envisages a period for compliance starting before the notice takes effect... I notice that paragraph P173.22 of Volume 2 of the Planning Encyclopedia states: "
