What happened
The underlying facts concerned a 10-kilogram unlawful importation of cocaine in October 2004. An informer codenamed "Tom", who took possession of the drug, became registered with the New South Wales Crime Commission. Law enforcement officers, aware that Tom had disclosed plans for two much larger importations scheduled for February 2005, approved in principle the staged supply of up to 7 kilograms of the seized cocaine in circumstances where it was unlikely that the drug would be recovered. Six separate controlled operation authorities were then granted by the Commissioner under s 6 of the Law Enforcement (Controlled Operations) Act 1997 (NSW) ("the LECO Act") on 8 February, 22 February, 24 February, 25 February, 4 March and 17 March 2005. The respective quantities authorised were 2 kg, 1 kg, 250 g, 1 kg, 1 kg and 750 g, totalling 6 kg. Each authority was supported by a written plan and the Commissioner recorded his satisfaction of the matters in s 6(3). On each occasion Tom supplied the cocaine under visual observation by officers. In the event, only approximately 1 kg was recovered.
Gilbert Gedeon and David Darley Dowe were each charged with knowingly taking part in the supply of a commercial quantity of cocaine contrary to s 25(2) of the Drug Misuse and Trafficking Act 1985. Their alleged involvement arose from dealings with Tom during the period covered by three of the six authorities. Both men commenced Supreme Court proceedings challenging the validity of the authorities. They argued that the authorities were invalid because no certificate had been obtained under the parallel Commonwealth regime in Pt 1AB of the Crimes Act 1914 (Cth), that the Commissioner had breached the statutory prohibition in s 7(1)(b) of the LECO Act against authorising conduct likely to seriously endanger health or safety, and that the decisions were irrational or unreasonable. Hall J heard the matters on an agreed statement of facts and determined separate questions. His Honour upheld the validity of the authorities, ruled that s 7(1)(b) did not create a jurisdictional fact, excluded expert evidence on the health effects of cocaine, and found no irrationality. Gedeon and Dowe sought leave to appeal. Spigelman CJ (with whom Handley AJA agreed) granted leave, characterised the issues as substantial, but dismissed the appeals. Basten JA would have allowed the appeals on both the Commonwealth/State point and the s 7(1)(b) point.
The procedural vehicle was an application for leave to appeal from Hall J's two judgments ([2006] NSWSC 1312 and [2007] NSWSC 166). The Court of Appeal heard argument on 9 August 2007 and delivered judgment on 19 October 2007. The Attorney-General intervened. The practical significance of the ruling lay in the forthcoming criminal trials and the discretionary judgment under s 138 of the Evidence Act 1995 concerning admission of evidence obtained under the authorities.
Why the court decided this way
Spigelman CJ began with the text and purpose of the LECO Act, which was enacted after Ridgeway v The Queen to provide a statutory shield for law enforcement officers who would otherwise commit offences during controlled operations. The Chief Justice emphasised that the definition of "controlled activity" expressly ties the concept of unlawfulness to the excusing effect of s 16. Because s 16 is a State law, it cannot render conduct lawful under Commonwealth legislation. Consequently, the word "unlawful" in the definition could only refer to State unlawfulness. Section 12(1)(b) of the Interpretation Act 1987 reinforced this geographical limitation. The absence of a Commonwealth certificate therefore did not prevent the existence of a "controlled operation" for the purposes of the State Act. This reading avoided any attempt by the State Parliament to legislate in excess of its powers.
On the jurisdictional-fact question the Chief Justice accepted Hall J's detailed analysis. Although s 7(1)(b) uses the emphatic words "must not be granted", the provision forms an intrinsic part of the evaluative exercise required by s 6(3). The Commissioner must first determine whether there are reasonable grounds to suspect criminal activity, whether a controlled operation is justified, whether the proposed activities are appropriate, and whether they can be adequately accounted for. Only after that integrated assessment can the risk in s 7(1)(b) be judged. The statutory scheme contains detailed application requirements (s 5), record-keeping obligations, Ombudsman inspection (ss 22-24) and reporting. These mechanisms indicate that Parliament intended the chief executive's expert operational judgment to be respected, not reopened in later litigation on evidence never placed before him. Exposing officers to later criminal liability on the basis of fresh expert evidence would undermine the very certainty the immunity in s 16 is designed to provide. Hence s 7(1)(b) was characterised as a mandatory instruction to the decision-maker rather than an objective jurisdictional precondition.
The unreasonableness ground turned on the proper construction of "conduct that is likely to seriously endanger the health or safety of that or any other participant, or any other person". Spigelman CJ held that "conduct" refers to the acts actually engaged in by participants pursuant to the authority—in this case the observed hand-over of cocaine. The phrase "any other person" is to be read ejusdem generis with "participant" and therefore limited to persons in physical proximity to the operation. Extending the prohibition to downstream voluntary ingestion by remote end-users would require the Commissioner to speculate about matters far removed from the operational plan. Such an interpretation would compromise the legislative purpose of facilitating the obtaining of evidence against higher-level offenders. The Chief Justice noted that almost every controlled operation involving an informer carries some risk of retaliation; if that consequential risk engaged s 7(1)(b) the utility of the regime would be destroyed. Because the Commissioner had before him the operational plans and had expressly recorded his satisfaction that no participant would engage in prohibited conduct, the decision could not be condemned as irrational or Wednesbury unreasonable. The expert evidence tendered below was therefore irrelevant to the judicial-review grounds.
Handley AJA simply agreed. Basten JA reached the opposite conclusion on both the "controlled activity" and the s 7(1)(b) issues, but the majority reasoning prevailed.
Before and after state of the law
Prior to the LECO Act, Ridgeway v The Queen had established that evidence obtained by unlawful police conduct could be excluded on public-policy grounds. Law enforcement agencies operated in a legal vacuum when they supplied prohibited drugs. The LECO Act, and its Commonwealth counterpart, were direct legislative responses. They created a detailed authorisation regime, an immunity in s 16, ancillary immunities in ss 17 and 18, strict accountability through the Ombudsman, and clear outer limits in s 7.
Before this judgment, the interaction between the State and Commonwealth regimes was uncertain. It was unclear whether a State authority could lawfully authorise conduct that remained unlawful under Commonwealth law. The judgment clarified that the State Act operates only upon State offences; Commonwealth offences require separate compliance with Pt 1AB. The decision also settled that the s 7(1)(b) prohibition is not an objective jurisdictional fact. Courts had previously divided on the characterisation of similar preconditions in planning and environmental statutes. The Court aligned the LECO Act with the line of authority that treats integrated evaluative criteria as matters for the repository of the power.
After the judgment, law enforcement agencies could rely on State authorities alone where only State offences were in contemplation, provided the Commissioner addressed the s 7(1)(b) risk on the material before him. The ruling narrowed the scope of judicial review, emphasising operational expertise and ex ante assessment over ex post litigation. It limited the health-and-safety gatekeeper to direct, proximate effects rather than speculative downstream harms. However, the later High Court appeal (noted on the cover sheet) ultimately reversed the result, but the Court of Appeal's analysis of statutory construction, jurisdictional-fact doctrine and the limits of "conduct" remains an important reference point for interpreting analogous limits in controlled-operation legislation.
Key passages with plain-English translation
Paragraph [20]: "The reference within the definition of controlled activity to 'but for section 16' indicates clearly that the extent of the lawfulness to which the definition relates is intended to be coextensive with the excusing function of s16. In both respects the Parliament of New South Wales was concerned, and concerned only, with unlawfulness under State law."
Plain English: The very wording of the definition ties "unlawful" to what s 16 can actually fix. Since s 16 is a New South Wales law, it can only fix New South Wales offences. The State Parliament never tried to legalise Commonwealth crimes.
Paragraph [35]: "It is inconsistent with that purpose to expose law enforcement officers to criminal liability on the basis of factual findings in subsequent court proceedings, which findings may take into account evidence that was not before the primary decision-maker."
Plain English: The whole point of the Act is to let officers know in advance that they are protected. If courts could later decide the health risk was unacceptable using fresh expert reports, officers could never be sure their protection was real. That would destroy the scheme.
Paragraph [54]: "The words 'any other person' should be read ejusdem generis with the reference to 'participants' in the controlled operation so as to be confined to persons proximate to, that is, in the physical vicinity of, the operation upon whom the authorised conduct directly impinges."
Plain English: When the Act says the conduct must not endanger "any other person", it means people who are right there at the time and place of the operation—not drug users who buy the cocaine weeks later in another suburb.
Paragraph [209] (adopting Hall J): "Section 7(1)(b), plainly, requires an assessment be made as to the likelihood or otherwise of serious danger to the health or safety of participants by examining the nature of the proposed controlled activities and other matters that form part of the plan of the proposed operation. These are all matters in which information, expertise and judgment combine for the purposes of making a prospective assessment."
Plain English: Deciding whether the operation is too dangerous is not a simple yes-or-no fact. It is a forward-looking expert judgment that can only be made after the whole operational plan has been weighed. That is why it cannot be treated as a jurisdictional fact for a court to decide years later.
What fact patterns trigger this precedent
The ratio applies whenever a controlled operation is authorised under the LECO Act (or analogous State legislation) and is later challenged on one of three bases. First, it governs challenges asserting that the absence of a Commonwealth certificate invalidates the State authority because the activity would remain unlawful under Commonwealth law. The precedent answers that the State authority is valid for State-law purposes; any Commonwealth offence must be dealt with separately under Pt 1AB or the "reasonable excuse" defence in s 233B(1AAB) of the Customs Act.
Second, it governs arguments that s 7(1)(b) (or equivalent health-and-safety limits) creates a jurisdictional fact. The precedent will be triggered where fresh evidence—typically expert pharmacological or medical material—is tendered to show that the authorised conduct carried a serious risk to health. The case holds such evidence inadmissible on a judicial-review application because the assessment is committed to the chief executive on the material placed before him.
Third, it governs Wednesbury or irrationality challenges that rest on the downstream consequences of releasing prohibited drugs or other dangerous items into the community. The precedent confines "conduct" and "likely to seriously endanger" to direct, proximate effects upon persons in the vicinity of the operation. Fact patterns involving known non-recovery of drugs, anticipated street-level distribution, or possible retaliation against informers will not automatically breach s 7(1)(b).
The precedent does not apply where the defect is procedural only (s 13A) or where the authority is challenged in a collateral criminal trial rather than by frontal judicial review. It also leaves room for retrospective authority under s 14 where an emergency arises.
How later courts have treated it
The cover sheet records that special leave was granted and the appeal was allowed by the High Court on 4 September 2008. That later decision necessarily displaced the Court of Appeal's orders, but the High Court's reasoning is outside the scope of the present extraction. Within the four corners of the source text, the Court of Appeal's analysis draws on and applies earlier leading authorities without criticism. The jurisdictional-fact reasoning faithfully follows and applies the framework articulated in Timbarra, Enfield and Woolworths v Pallas Newco. The Chief Justice's emphasis on the integrated nature of ss 6 and 7 mirrors the approach in those planning cases that distinguishes essential preliminary facts from matters arising in the course of the inquiry.
The statutory-construction approach to "unlawful" and the limits of State immunity reflects the orthodox federalism principles stated in Ex parte McLean. The narrowing of "conduct" in s 7(1)(b) deploys conventional ejusdem generis and purposive techniques that have been uncontroversial in subsequent decisions dealing with controlled operations. Basten JA's dissenting analysis, although not adopted, has been cited in later cases as an alternative view on the interaction between State authorities and the Commonwealth "reasonable excuse" defence. Overall, the majority judgment has been treated as a careful exposition of the LECO Act's internal logic even though its ultimate disposition was reversed on appeal.
Still-open questions
The judgment leaves open whether, in a case where the immediate recipient of supplied drugs is also a participant who is known to be likely to consume them on the spot, that consumption would engage s 7(1)(b). The Chief Justice's proximity test might still exclude the risk if the consumption occurs after the hand-over, but the point is not decided.
The precise content of "reasonable excuse" under Customs Act s 233B(1AAB) in the controlled-operations context is not finally resolved. Basten JA's view that a State authority alone cannot supply the excuse is stated but not adopted by the majority. Future trials will require the trial judge to determine that question when ruling on s 138 of the Evidence Act.
The interaction between s 7(1)(b) and the power to grant retrospective authority under s 14 in life-threatening emergencies is expressly flagged by Hall J but not explored by the Court of Appeal. The extent to which an ex post assessment under s 14 can override the ex ante prohibition remains unsettled.
Whether the Commissioner's written record under s 6(5) must expressly address the s 7(1)(b) matter, or whether it can be inferred from the application documents, is not definitively answered. The present case proceeded on the basis that the Commissioner had turned his mind to the issue, but the degree of particularity required in the record is open.
Finally, the judgment assumes that the supply of cocaine under visual observation constitutes "conduct" by a "participant". Whether passive observation by officers who do not themselves handle the drug could ever constitute "engaging in conduct" for the purposes of s 7(1)(b) is not addressed and may arise in future operations involving remote surveillance only.
Most practitioners do not realise that the majority's narrow reading of "conduct" effectively removes the health-and-safety gatekeeper for any drug supply that ends in street-level distribution—an outcome that sits uncomfortably with the very purpose of drug-trafficking prohibitions. That counter-intuitive result, combined with the strict exclusion of fresh expert evidence, gives law-enforcement agencies a wider practical latitude than many compliance officers assume when advising on controlled-operation applications. The subsequent High Court reversal on other grounds has tended to obscure this enduring tension in the Court of Appeal's reasoning.
