(d) The relevant acts or omissions, having been identified, it then becomes necessary to determine whether the "conduct" is of a nature, kind or quality that is "… likely to seriously endanger the health or safety" of the specified person or persons (where the issue is one of health or safety as distinct from damage to property).
(e) This last-mentioned aspect is not concerned with mere risk arising from "conduct". It is directed to whether or not the relevant authorised "conduct" is "likely to" produce the stated harmful consequence. In this respect, it is clear that "the conduct" must be assessed objectively in order to determine whether it has the requisite causative character.
61 Such an approach is not unlike that which has been adopted and applied with similar statutory concepts. Hence, for example, the code definition of murder in s.302(2) of the Criminal Code (Q) is expressed to include an unlawful killing within the specified circumstances stipulated in s.302(2) of the Code, namely:-
"(2) If death is caused by means of an act done in the prosecution of an unlawful purpose, which Act is of such a nature as to be likely to endanger human life ;" (emphasis added)
62 In Stuart v. The Queen (1974) 134 CLR 426 at 438 per Gibbs, J. observed that, whether or not the act falls within the provision, is to be determined by a test that is "purely objective". See also Regina v. Fitzgerald (1999) BC 9901392, Queensland Court of Appeal (per McPherson, JA.).
63 In determining the question whether the conduct authorised by the authorities that are in question in these proceedings could be said objectively to be conduct that is "likely to seriously endanger the health or safety" of specified persons, the answer depends upon whether the sale and the supply of the cocaine (being the relevant authorised "conduct") constituted acts or activities that, in themselves, were likely to produce the stated consequence. Arriving at the answer to this question in a particular case may be aided by applying one or both of two tests well known to the criminal law, the natural consequence test and the reasonable foresight of consequence test.
64 The first has been applied in circumstances where the action of the victim which resulted in death was the natural consequence of the particular conduct of the accused and therefore it could be said that the accused's actions caused the death: Regina v. Beech (1912) 7 Cr. App. R. 197. The second test has been applied in circumstances where the action of the victim leading to death can be said to have been a reasonably foreseeable consequence of what the accused said and did. In those circumstances, the accused can be said to have caused the death: Regina v. Roberts (1971) 56 Cr. App. R. 95; DPP v. Daley (1980) AC 237.
65 The authorities to conduct the controlled operations in question in these proceedings, identified the "conduct" by specifying the "controlled activities of the nature specified opposite". This is a reference to the activities in Column 2 of the Table to the authorities which identified the particular acts as including the possession and the supply of cocaine to Tom as informer and to other specified persons who, upon the basis of information contained in the applications for the authorities were identified as targets of the proposed controlled operations.
66 The authorities specifically stated (paragraph 5(b)) "no participant will engage in conduct that is likely to seriously endanger the health or safety of that or any other participant, or any other person, or to result in serious loss or damage to property".
67 The applications also stated (paragraph 3(d)) that "the controlled operations will be capable of being accounted for in sufficient detail to enable the reporting requirements of the Act to be fully complied with".
68 Whether one applies what has been referred to above as the natural consequence test or whether one simply applies an objective test to the phrase "likely to seriously endanger the health or safety of specified persons" the prohibition in s.7(1)(b) will only apply where it can be said that the authorised activities themselves are likely to result in or produce the deleterious consequences referred to in that provision. If harm to health and safety is dependent upon and will only arise through the separate voluntary act or acts on the part of a third person as by ingesting cocaine in quantities that can produce that result, then it cannot, in my opinion, be said the authorised activities of selling and supplying cocaine in themselves contravened s.7(1)(b).
69 "Likely to endanger" is not to be equated with or embrace mere risk or even material risk. See, for example, Aqua Vital Australia Limited v. Swan Television (1995) WASC (Wallwork, J.) BC 9503674 at 5. That phrase does not have the same meaning as "a risk to". In its statutory context, "endanger" carries the dictionary meaning "cause the danger of, make probable, (something untoward)": Shorter Oxford English Dictionary, Volume 1, p.823. The phrase involves the notion of direct causation. The law in many areas has distinguished between events or circumstances that are conducive to or that facilitate an event from circumstances that can be said to be the cause of them. One person's act may not be the cause of an event even though it was an essential condition of it: March v. Stramere (1990-1991) 171 CLR 506, 517 per Mason, CJ.
70 Controlled operations may, depending upon circumstances, involve a risk to the health and safety of specified persons. But s.7(1)(b) is not, as I have indicated, directed to risk per se. The information provided in an application made under s.5 of the Act, including, in particular, that in the plan of the proposed operation, and any other relevant information known to the chief executive officer must be examined as so as to ensure that the particular conduct (the acts and/or omissions) proposed for a controlled operation will not, inter alia, be likely to seriously endanger the health or safety of the specified persons.
71 The issue of the causative consequence with which s.7(1)(b) is concerned has some parallel in the area of tortious liability in circumstances in which the victim sues an occupier of allegedly unsafe premises, having been injured by the voluntary criminal act of a third party. In Modbury Triangle Shopping Centre Pty. Limited v. Anzil (2000) 205 CLR 254, Gleeson, CJ. at 269 drew a distinction between the occupier's omission which might be said to have facilitated the crime but not to have caused the victim's injuries. Leaving to one side the fact that a positive act and an omission may be capable of producing different consequences, the circumstances postulated in the plaintiff's submissions, namely, the later ingestion of cocaine by unspecified persons, would involve intervening voluntary criminal acts of a third party or parties (the lawful nature of the acts arise by virtue of s.12 of the Drug Misuse and Trafficking Act 1985 (NSW) - self-administration of prohibited drugs). Such acts of third parties constitute the necessary intervening circumstances before any harm or safety issue could possibly arise.
72 I am accordingly of the opinion that upon the proper construction of s.7(1)(b) of the Act, the "conduct", the controlled activities authorised, did not amount to or constitute conduct that was in itself capable or likely to give rise to serious danger to the health or safety of the persons referred to in the section. Whether cocaine, a prohibited substance can, in fact, produce, in a particular situation, deleterious consequences to health and safety (and I am prepared to assume that, at least in some circumstances, the ingestion of the drug is capable of providing such harmful effects) will no doubt depend upon the facts concerning the particular consumption including the nature, extent and frequency of such consumption. The provisions of s.7(1)(b) have, in my opinion, been drafted in such a way as to require a direct causal relationship between the conduct in question and the stated consequence to health and safety.
73 Accordingly, upon the proper construction of s.7(1)(b), I do not consider that the authorities were issued in contravention of that section. In particular:-
