Provisions

edit

Section 7

edit

Section 7 of the act, concerned with service of documents by post, replaced section 26 of the Interpretation Act 1889 (52 & 53 Vict. c. 63).[8] It states that

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.[9]

Interpretation of the words unless the contrary is proved is discussed in the case of Calladine-Smith v Saveorder Ltd, as to whether the "contrary" means the contrary of the allegation that the letter was properly addressed, prepaid and posted, or whether it refers to the contrary of the deeming provision that the letter in question was delivered in the ordinary course of post. In this particular case, a letter was shown to have been properly addressed, pre-paid and posted, but not received. On a balance of probabilities the court accepted that the "contrary" to the deemed provision had been proved, the letter was not received, and therefore the deemed provision could not hold.[10]

Section 16 – General savings

edit

The following cases are relevant to this section:

  • Hough v Windus (1884) 12 QBD 224, CA
  • R v Fisher (Charles) [1969] 1 WLR 8, CA
  • R v West London Stipendiary Magistrate, ex parte Simeon [1983] AC 234, HL

Section 18 – Duplicated offences

edit

Section 18 of the act provides:

Where an act or omission constitutes an offence under two or more Acts, or both under an Act and at common law, the offender shall, unless the contrary intention appears, be liable to be prosecuted and punished under either or any of those Acts or at common law, but shall not be liable to be punished more than once for the same offence.[11]

This section replaces section 33 of the Interpretation Act 1889 (52 & 53 Vict. c. 63).[12] Humphreys J. said that that section did not add anything to the common law, or detract anything from it.[13]

"... shall not be liable to be punished more than once for the same offence"

edit

The words "same offence" at the end of section 18 of the act do not mean "same act" or "same cause". A person may be punished more than once for the same act.[14] Two prosecutions for a single false statement in a brochure is not oppressive.[15]
