The first question to be decided is whether s 107(c) creates for the present purpose one or several offences. Here, with respect, I find myself in disagreement with the learned Judge. It seems to me that the opening words of s 107, read with the specific words of sub-section (c), create two offences only, one of knowingly sending and one of knowingly attempting to send a postal article possessing any one or more of certain characteristics. The complaint only charges the defendant with knowingly sending, not with knowingly attempting to send. If the postal article in question has more than one objectionable word, mark or design, if it has some of such words, marks or designs thereon and some therein and some on its envelope and some on its cover, nevertheless only one offence, in my view, is created. If there are words to which all the five adjectives can be applied, or a collection of words to some of which each of the five adjectives can be applied separately, still, in my view, only one offence is created. Were it otherwise, for example, if a man knowingly sent by post a postal article which contained one word both indecent and obscene, another indecent word, another blasphemous word and another libellous word, and if all of those words were grossly offensive as well, he would commit ten offences. The principles adopted by this Court in R v O'Loughlin; Ex parte Ralphs [(1971) 1 SASR 219] might save the defendant from being convicted more than once in respect of the same word, but could not on this interpretation save him from several convictions for several different words. I cannot think that Parliament intended anything like this. I think that the case falls into the line of authorities represented by Smith v Perry [[1906] 1 KB 262]; Hedberg v Woodhall [(1913) [1913] HCA 2; 15 CLR 531]; Moore v Allchurch [[1924] SASR 111]; per Napier J., as he then was, at p 119; Thomson v Knights [[1947] KB 336]; Naismith ...; and O'Sullivan v Truth and Sportsman Ltd [(1957) [1957] HCA 8; 96 CLR 220]. I agree with Mr Cox that the observations of the learned Judges of the High Court in the last-mentioned case at p 224 are practically conclusive on this point.
The true distinction, broadly speaking, it seems to me, is between a statute which penalises one or more acts, in which case two or more offences are created, and a statute which penalises one act if it possesses one or more forbidden characteristics. In the latter case there is only one offence, whether the act under consideration in fact possesses one or several of such characteristics. Of course, there will always be borderline cases and if it is clear that Parliament intended several offences to be committed if the act in question possesses more than one of the forbidden characteristics, that result will follow. See, for example, Bastin .... So it may be, as Mr Cox suggests, that s 107(a) creates several offences if more than one of the things referred to therein is enclosed in the same postal article, but it is not necessary to decide that. In s 107(a) the various prohibited things are each separated by the word 'or', whereas in s 107(c) the word 'or' only appears once before the last item in the collection, and this has sometimes been regarded as a feature of importance, though with respect, it seems to me that it can only possess very limited significance.
I think, then, that s 107(c) only creates one offence of sending a postal article of the kind referred to. This conclusion renders it unnecessary to discuss many of the points canvassed about the form of the complaint in the event of the Court holding that more than one offence was alleged in it.
