An information was laid against him for that on 2nd July at divers places in New South Wales he was knowingly concerned in the commission of an offence committed by Gee Kee Way in that the said Gee Kee Way, being a prohibited immigrant, was contrary to the Immigration Act found in the Commonwealth in contravention or evasion of the said Act, to wit, at Burwood. The information was framed under sec. 5 of the Crimes Act which enacts that any person who aids, abets, counsels or procures or by act or omission is in any way directly or indirectly knowingly concerned in, or party to, the commission of any offence against any law of the Commonwealth shall be deemed to have committed that offence and shall be punishable accordingly. The information does not specify the precise act or omission by which the appellant was alleged to be knowingly concerned in Gee Kee Way's offence. But it may be taken that it covered accompanying that Chinaman upon this journey from the Victorian border in the tourist car, his transfer to the taxi-cab at Liverpool and the journey therein that was abruptly brought to an end at Burwood. Gee Kee Way's offence, that is, the principal offence, laid in the information is constituted by sec. 7 of the Immigration Act. So far as relevant to the charge, the elements in which the offence consists are, possessing the character of a prohibited immigrant, and being found in the Commonwealth of Australia in contravention or evasion of the Act. Another offence under sec. 7 is entering the Commonwealth, but that is not charged in the information. As a result of the amendment of 1935, sec. 7 also creates an offence consisting in no more than being deemed to be a prohibited immigrant offending against the Act. As stowaways are, under sec. 9A, persons deemed to be prohibited immigrants, as distinguished from actually prohibited immigrants, if the Act really intends to draw such a distinction, it may be said that Gee Kee Way's presence in Australia has been made the subject of a charge under the less appropriate part of sec. 7. But perhaps this fine distinction is not really intended and the amendment of sec. 7 was redundant. The expression "found within the Commonwealth" has occasioned some difficulty in other cases. Does it mean that there must be a discovery of the immigrant, or is his mere presence in Australia enough to make him an offender? If an essential ingredient of the offence is a "finding," the appellant can hardly be said to be knowingly concerned in that constituent fact. The last thing he wanted was that Gee Kee Way should be found or discovered. But I think the word "found" does not look to the nature of the offence but merely to its disclosure. The offence of the immigrant consists in being within the Commonwealth. Here again, however, the prosecution encounters a difficulty. How, by any act or omission in New South Wales, was the appellant knowingly concerned in Gee Kee Way being within the Commonwealth? The offence is not being at Liverpool, or being at Burwood, or being in a taxi-cab. It is being within the territorial boundaries of Australia. Movement or other activity within the territory is no part of the offence. Concealment is no part of the offence. The words "in contravention or evasion of the Act" probably demand no further constituent element to make the offence than being a prohibited immigrant. It is said that really they mean "without authority or excuse," e.g., without permit or licence. But however that may be, it is clear that the condition expressed in those words is satisfied rather by the manner of Gee Kee Way's entry into the Commonwealth than his journey from the border of New South Wales to Burwood or any state or condition assumed by Gee Kee Way in that transit. He was no more and no less in the Commonwealth because of his transportation in New South Wales. How can it be said that the appellant was knowingly concerned by acts and omissions during that period in Gee Kee Way's existence within the geographical area called the Commonwealth? It is nothing to the point that at an earlier time the appellant may have facilitated Gee Kee Way's entry and, therefore, shared in the responsibility for his presence in Australia. That is not the charge against the appellant. Nor is it, I think, anything to the point that the appellant was endeavouring to make it less probable that Gee Kee Way would be compelled to depart from the Commonwealth. His activities may have tended to delay that event, but that is not the charge. Under sec. 5 of the Crimes Act the principal offence must actually be committed before the accessory is guilty. It is not a provision dealing with mere incitement independently of the commission of the offence incited. It is an aiding and abetting section (See per Isaacs J. in Walsh v. Sainsbury[6]). It is, therefore, necessary to see what, during the relevant interval of time and at the relevant place or places, the principal offender did as amounting to an offence. Then it can be found whether the abettor was knowingly concerned therein.
