12 The gravamen of the Crown case at trial was that the appellant and the man Tier had been parties to a joint venture, the objective of which was the manufacture of amphetamine. Amphetamine is a prohibited drug for the purposes of the Drug Misuse and Trafficking Act. Schedule 1 to the Act provides for certain prescribed levels of culpability related to the amount of the drug involved in the particular case. In the case of amphetamine the traffickable quantity is 3 grams; the indictable quantity is 5 grams; and the commercial quantity is 250 grams. The indictment presented against the appellant and the man Tier charged an intended manufacture of an amount not less than the commercial quantity of 250 grams.
13 The point now taken for the appellant is that the learned trial Judge fell into error by not directing the jury specifically as to the alternative verdict open to them pursuant to section 24(3). The appellant's contention is, put simply, that the evidence at trial was so imprecise as to relevant quantities, that it remained open to the jury to be satisfied beyond reasonable doubt that the appellant had knowingly taken part in the manufacture of amphetamine, but not to be satisfied beyond reasonable doubt that the amount in question had been not less than the prescribed commercial quantity of 250 grams.
14 There was ample evidence at trial to associate the appellant with certain factory premises which had been fitted out, in effect, as a laboratory capable of manufacturing amphetamine. There was a deal of evidence similarly available to the jury to establish that the appellant had, at material times, busied himself in the ordering of equipment apt for use in the manufacture of amphetamine. There was evidence that the man Tier had purchased, at a relevant time, 14 drums containing ethylphenylacetate, a substance capable of use in connection with the manufacture of amphetamine. There was ample evidence before the jury that the appellant and the man Tier had, very shortly thereafter, driven to the relevant factory premises taking with them one of the drums in which the ethylphenylacetate had been delivered to the man Tier. There was no evidence whether the particular drum had been full or empty at the time of its transportation to the factory, but it was in my opinion well open to the jury to infer beyond reasonable doubt from the entirety of the evidence in the Crown case that the drum had been full rather than empty, and that it had been transported to the factory for the purpose of its contents being used in connection with the manufacture of amphetamine.
15 There was, in the Crown case at trial, evidence capable of being accepted by the jury and which, if so accepted, clearly established as between the appellant and Tier an association of substance in connection with the activities being carried on at the relevant factory premises. There was, as well, evidence of intercepted telephone conversations, which evidence, if accepted by the jury, was capable of giving rise to an inference reached beyond reasonable doubt that the appellant was to be heard in certain of the conversations speaking in terms appropriate to a discussion of drug manufacture.
16 The evidence at trial established that the 14 drums of ethylphenylacetate had been delivered on 23 March 1992 to a guest house at Moss Vale, being premises with which Tier had an association of substance. The transfer of the one drum to the relevant factory premises took place on 25 March 1992. On 16 August 1992 a search was made of the guest house premises. Various materials were found, the nature of which was such as to be capable of giving rise to an inference reached beyond reasonable doubt that Tier was involved in the illicit manufacture of drugs. On this occasion 13 of the 24 drums in which the ethylphenylacetate had been delivered in March 1992 were located. The drums were empty. Fingerprints found on four of them were identified, beyond reasonable doubt, as being those of the present appellant.
17 The Crown called at trial an analytical chemist called Murtagh. He gave evidence of a chemical process, known as the Leuckardt process, in use for the manufacture of amphetamine. He gave evidence that ethylphenylacetate was a necessary ingredient in this particular process. He estimated that the quantity of ethylphenylacetate contained in the 14 drums when full would have been sufficient to produce by means of the Leuckardt process 41 kilos of amphetamine oil or 56 kilos of amphetamine salt.
18 The appellant did not give evidence at his trial. He had made a dock statement at an earlier trial. The Crown tendered a transcript of that earlier dock statement. In the dock statement the appellant put forward a version consistent with the absence of any intent on his part to take any part whatsoever in any manufacture of any quantity of prohibited drug. It was undoubtedly open to the jury to reject this version; and in my opinion the verdict of the jury cannot be understood sensibly as having done other than to reject it in fact.
19 The contention upon which the appellant now relies concedes that it was not necessary that the Crown prove at trial that a quantity of not less than the commercial quantity of amphetamine had been manufactured in fact; but that there was a necessary mental element in the offence charged in the indictment, and that such mental element entailed proof by the Crown beyond reasonable doubt that the appellant had taken part in the illicit manufacture of amphetamine knowing that the enterprise in which he was thereby participating was an enterprise having as its objective the intended manufacture of not less than the relevant commercial quantity of 250 grams. The submission draws attention to the fact that the Crown case at trial did not establish in terms the production in fact of any particular quantity of amphetamine. This entailed, so the submission runs, that the learned trial Judge ought to have left to the jury in precise and carefully formulated terms the possibility of their returning an alternative verdict pursuant to section 24(3). Since it is clear that the learned trial Judge did not in fact give such directions, it is contended that his Honour fell into demonstrated error.
20 In considering the submissions now put for the appellant, it is appropriate to commence by considering the relevant course of events at trial.
21 After the whole of the evidence had been taken, the learned trial Judge sent the jury away for a time, and embarked upon a lengthy discussion with all counsel then appearing, the discussion having to do with the attempted resolution of various questions of law. The Judge handed down to all counsel a document, which his Honour had prepared, setting out various matters with which his Honour was proposing to deal in his summing up. The contents of that document became the basis of the very lengthy discussions which then ensued.
22 In that context, and after the discussions had proceeded for some time, counsel then appearing for the appellant said this:
"While we're looking at this, one matter, my understanding is that the alternative to the count is also to be placed before the jury."
