Thomas v. The King 1, viz., whether an honest and responsible H. belief, although erroneous, in a set of facts which if true would take the accused outside the definition of the offence charged affords a good defence. It is simply a case where a person showing complete indifference to the fulfilment of the duty laid on her by the legis- lature says: "I didn't know." In relation to a British provision in pari materia, Lord Wright in McLeod v. Buchanan 2 says
The section is imperative, and precisely specifies the act or default constituting the offence, which is sufficiently established by proof of the matters specified. Intention to commit a breach of the statute need not be shown. The breach in fact is enough."
Special leave should be refused.
DIXON J. The applicant was convicted summarily of an offence against S. 30 of the Road Traffic Act 1934-1939 (S.A.). The charge was that she permitted a person, not being the holder of a licence for the time being in force, to drive a motor vehicle on a road. She appealed against that conviction to the Supreme Court. Cleland J., who heard her appeal, set aside the conviction on the ground that she believed that the driver in question held a licence which was in force and that she had reasonable grounds for her belief. His Honour appears further to have considered that she could not be said to have permitted him, as a person not holding such a licence, to drive the motor vehicle unless she knew that he was unlicensed, quite independently of the question of the reasonableness of her belief to the contrary.
The Full Court of the Supreme Court, consisting of Murray C.J., Angas Parsons and Napier JJ., allowed the appeal and restored the conviction. Their Honours were all of the opinion that the applicant had not made out in fact any defence of mistake on reasonable grounds and that under the provisions of S. 30 it was not incumbent upon the prosecution to establish that the applicant knew that a licence for the time being in force was not held by the person whom she permitted to drive the motor vehicle.
Murray C.J. went further and decided that under S. 30 mistake would not afford a defence, that is to say, it would not amount to an answer to the charge of permitting if a defendant proved that on reasonable grounds he honestly believed that the person he per- mitted to drive his car held a licence then in force.
From the decision of the Full Court the applicant now seeks special leave to appeal to this Court.
A consideration of the provisions of the statute and of the author- ities cited in a somewhat full argument has not disclosed any reason
