Section 19 Time limit for summary proceedingsI1I2

Proceedings for an offence under section 2(1) or (2) or section 14(1), (3) or (4) may be brought within the period of 6 months beginning with the date on which evidence sufficient in the opinion of the prosecutor to justify the proceedings came to the prosecutor’s knowledge.

But no such proceedings may be brought more than 3 years—

A certificate signed by or on behalf of the prosecutor which states the date on which evidence referred to in subsection (1) came to the prosecutor’s knowledge is conclusive evidence of that fact, and such a certificate which purports to be so signed is to be treated as being so signed unless the contrary is proved.
