Defence of due diligence

61.—(1) In any proceedings for an offence of contravening a provision of these Regulations listed in Schedule 4, it shall be a defence for the person charged to prove that he took all reasonable precautions and exercised all due diligence to avoid the commission of the offence by himself or by a person under his control.

(2) If in any case the defence provided by paragraph (1) involves the allegation that the commission of the offence was due to an act or default of another person, or to reliance on information supplied by another person, the person charged shall not, without leave of the Court, be entitled to rely on that defence, unless –

(a)at least 7 clear days before the hearing; and

(b)where he has previously appeared, or been brought, before a court in connection with the alleged offence, within one month of his first such appearance,

he has served on the prosecutor a notice in writing giving such information identifying or assisting in the identification of that other person as was then in his possession.
