"Where the council are satisfied that premises in the City are being used as a sex establishment without a licence in breach of Schedule 3 they may serve a closure notice in respect of those premises."
"Subject to subsection (2) below [which is immaterial] the council may, not less than 14 days and no later than 6 months after the service of a closure notice make a complaint to a justice of the peace acting for the petty sessions area in which the premises are situated for a closure order in respect of that closure notice."
"Service of a summons issued by a justice of the peace on a person other than a corporation may be effected- (c) by sending it in post in a letter addressed to him at his last known or usual place of abode."
"Any summons or other document served in manner authorised by the preceding provisions of this rule shall, for the purposes of any enactment other than the Act of 1980 or these Rules requiring a summons or other document to be served in any particular manner, be deemed to have been as effectively served as if it had been served in that manner."
"(i) at least one person having control of or an interest in the business carried on in the premises. (ii) the occupier of any other part of the building in which the premises are situated and to which, in the opinion of the council, access would be impeded if an order under section 4(5)(a) below were made in respect of the premises."
"Where a summons issued under subsection (3) above is served a notice stating the date, time and place at which the complaint will be heard shall be served on all persons upon whom the closure notice was served under section 3(2)(a)(ii) and (b) above."
"If, on hearing the complaint, the court is satisfied that -- (a) the closure notice was properly served." (there then follows the requirements of substance which give rise to the complaint) "... it may make an order under this section."
"I sought to emphasise that the fact that a procedural requirement states that something shall be done does not mean that if it is not, that the result is a nullity. It is very important to look at the intention of the legislation in assessing the requirement. It may be an obligation which is clearly set out, but the consequences of not complying with the obligation depend very much upon what is the statutory intent of the legislation as a whole. In this case, as I have sought to make clear, the purpose of the legislation so far as the occupiers of the basement were concerned is clear. "
"It is important not to achieve any result which causes injustice to occupiers, but equally it is important to come to an interpretation which does not frustrate the City of Westminster in the interests of the public to enforce the legislation with which we are here concerned."
"It seems to me that the requirement of section 4(5)(a) that, on the hearing of the complaint, the court has to be satisfied that the closure notice was properly served means what it says. It has to have been properly served on those upon whom it ought to have been served. I agree with the Lord Chief Justice that it is unhelpful to ask whether these provisions are mandatory or directory. Plainly the hearing of the complaint cannot properly proceed if those who ought to have been served have not been served, nor, importantly, if they have not been given due notice of the hearing of the complaint."
