It is difficult to avoid a feeling that, if the magistrate had given complete expression to the views which he formed as to the facts of this case, the legal difficulties which have been argued before this court and the Supreme Court or many of them would have been found to be academical. The defendant who describes himself as a general merchant, professed great knowledge of the road system of South Australia and possessed a lorry said to be owned by his wife which was found suitable for heavy carrying work showed no hesitation in accepting an order over the telephone for the carriage of an agricultural tractor from Adelaide to Halbury. The time for the delivery of the tractor to him was not fixed by the consignor and the defendant went away for the week end from Friday, 17th January 1936. When he returned on the evening of Monday, 20th, he found that his son, who, in his father's absence had charge of the business, had received a telephone message that the tractor was ready for delivery and that the job was urgent, and acting on the message had obtained the tractor and carted it to the consignee. The natural route to Halbury lay over a controlled route within the meaning of the Road and Railway Transport Acts 1930 and 1931. Sec. 14 (1) of those Acts says that "the board may by order, in relation to any controlled route or routes, fix a day after which it shall not be lawful for any unlicensed person to operate any vehicle on that route or those routes for the carriage of passengers or goods or both for hire." The son was caught using the controlled route and the father says that when he learnt what the son had done he said he should not have done it on any consideration whether urgent or not. According to the defendant his own intention had been to deliver the tractor himself without driving on the controlled route but following a road or roads which he said he knew. On the part of the complainant it is said that he could not have avoided crossing or using some controlled route. But upon this dispute of fact no finding seems to have been made. The son was convicted of an offence against sec. 14 (2) consisting in driving on a controlled route a vehicle for the purpose of carrying goods for hire not being the holder of a licence or a person employed by one. The father was then prosecuted under the same sub-section for causing the vehicle to be driven on the controlled route for the purpose of carrying goods for hire. He was convicted before a special magistrate, the material part of whose findings is as follows: - "I am bound to say I am not very satisfied with this part of the evidence. I think it improbable that the father intended to carry the goods himself on an uncontrolled route. It seems more probable that the son being employed for the purpose of delivering goods would have received his father's instructions on the matter. However, in my opinion, although the prosecution must prove this aspect of its case beyond all reasonable doubt, and I think that mens rea is a necessary ingredient of this part of the offence, bearing in mind the objects of this legislation, it appears to me in acting as he did the defendant must be taken to have intended what I think are the natural and probable consequences of his act, and that he in fact did cause this vehicle to be driven on the controlled route on this occasion, and I think therefore there must be a conviction." Not without some hesitation I have come to the conclusion that we ought not to treat this statement as necessarily meaning that it was the defendant's purpose to drive the lorry himself on a controlled route or that he actually knew or anticipated that his son would do so. In the Supreme Court Angas Parsons J., before whom the appeal from the special magistrate came, treated the facts as being that the son acted without the father's knowledge or express authority. On the appeal Murray C.J. and Richards J. treated the case as one in which a person in the position of a servant acts within the course of his authority but without the master's privity or direction. We did not give special leave for the purpose of reviewing the findings of fact or the interpretation of the special magistrate's decision and I think we should accept the view on these matters of the Supreme Court. Angas Parsons J. quashed the conviction on grounds which are fully set out in his judgment but which may perhaps be compendiously stated as that the defendant, having no guilty knowledge of what his son was about to do or did, could not have caused him to do it. In the Supreme Court Murray C.J. and Richards J. upheld this decision on a different ground - a ground depending upon a strict grammatical construction of the sub-section constituting the offence. That sub-section is as follows: - "After the appointed day no person shall on any controlled route drive any vehicle or cause any vehicle to be driven for the purpose of carrying passengers or goods or both for hire - (a) unless he is the holder of a licence or is a person employed by the holder of a licence to drive such vehicle: (b) otherwise than in accordance with every term and condition of a licence granted to himself or the person by whom he is employed." Their Honours gave it the meaning which would grammatically result from the position of the words "on any controlled route" after the word "shall" and before the words "drive ... or cause." Omitting the words "drive any vehicle" which are not relevant to the charge the section says "no person shall on any controlled route cause to be driven." Their Honours accordingly, construing the section strictly, regarded it as making it necessary that the causing as opposed to the driving should be done on a controlled route. I concede that grammatically this is the literal meaning of the words. But, as I said in Dignan v. Australian Steamships Pty. Ltd.[2], "English being a positional language, it is sometimes impossible to be certain how adjectival and adverbial phrases should be attached." In the present case it appears to me indisputable that the draftsman has made a grammatical error. I do not think that his error so obscures his meaning or clouds it with so much doubt that we ought to refrain from interpreting the sub-section at the expense of strict grammar. I feel quite clear that the adverbial phrase "on any controlled route" was intended to modify the verb "to be driven" and not the verb "cause." Being clear about it there is no reason why I should not interpret the section accordingly. In this view the fact that the defendant was not upon a controlled route when he did the acts which the magistrate found to amount to causing the offence of the son is no answer to the charge against the defendant. But upon the facts of the case as I have stated them I do not think that the magistrate's conclusion that the defendant did cause the son's offence is correct. "Cause" may have very many different meanings and applications. In the present case we are dealing with the causation of a criminal offence. When it is expressly made an offence for one man to "cause" another to commit what is forbidden as a crime we ought not to give any wide or general application to the word "cause." In this sub-section I take it to mean to procure or bring about. It refers to some intentional or conscious production of the effect. Consequences are infinite and I think that the present section meant to forbid only doing an act knowing or intending that it should produce the consequence that a vehicle is driven upon a road for the purpose of carrying persons or goods for hire if it turns out that the road is a controlled route. For this reason I think the judgment of the Supreme Court is correct. I may add that I do not think that the point argued by Mr. Ligertwood that the order of the Transport Control Board was invalid is well founded.
