“The notice of intent must be given before the end of the period of 6 months beginning with the first day on which the authority has sufficient evidence of the conduct to which the financial penalty relates.”
“Where an Act authorises or requires any document to be served by post (whether the expression “serve” or the expression “give” or “send” or any other expression is used) then, unless the contrary intention appears, the service is deemed to be effected by properly addressing, pre-paying and posting a letter containing the document and, unless the contrary is proved, to have been effected at the time at which the letter would be delivered in the ordinary course of post.”
“The general rule in cases in which a period " is fixed within which a person must act or take the consequences is that the day of the act or event from which the period runs should not be counted against him”
“It is also clear under a rule that has been consistently applied by the courts since Lester v. Garland (1808) 15 Ves. Jun. 248, that in calculating the period that has elapsed after the occurrence of the specified event such as the giving of a notice, the day on which the event occurs is excluded from the reckoning. It is equally well established, and is not disputed by counsel for the tenant, that when the relevant period is a month or specified number of months after the giving of a notice, the general rule is that the period ends upon the corresponding date in the appropriate subsequent month, i.e. the day of that month that bears the same number as the day of the earlier month on which the notice was given. The corresponding date rule is simple. It is easy of application. Except in a small minority of cases, of which the instant case is not an example, all that the calculator has to do is to mark in his diary the corresponding date in the appropriate subsequent month. Because the number of days in five months of the year is less than in the seven others the inevitable consequence of the corresponding date rule is that one month's notice given in a 30 day month is one day shorter than one month's notice given in a 31 day month and is three days shorter if it is given in February. Corresponding variations in the length of notice reckoned in days occur where the required notice is a plurality of months.”
