Notwithstanding section 127(1) of the Magistrates' Courts Act 1980, a magistrates' court may try an information or written charge relating to an offence under section 66E or 66F if the information is laid or the charge is issued—
before the end of the period of 3 years beginning with the day on which the offence was committed, and
before the end of the period of 6 months beginning with the day on which evidence which the prosecutor thinks is sufficient to justify a prosecution comes to the prosecutor's knowledge.
A certificate signed by or on behalf of a prosecutor stating the date on which evidence described in subsection (1)(b) came to the prosecutor's knowledge is conclusive evidence of that fact.
