This is a pre-trial Victorian Supreme Court ruling (Cummins J) on whether admissions recorded by undercover police during an extended covert operation (B Series) are admissible. The defence argued the recordings were involuntary, unfair and contrary to public policy because they were elicited by prolonged undercover role-play. The judge found Ghiller was a free citizen, not in custody, spoke voluntarily and enthusiastically, was not overborne or induced into committing offences by police, and the operation was lawful and controlled. The recordings were reliable and corroborated; public policy did not require exclusion. The covert recordings were therefore admitted.

This ruling is a pre-empanelment admissibility decision in the Supreme Court of Victoria (Criminal Division) by Cummins J, delivered 9 September 2003 in DPP v Ghiller [2003] VSC 350. The court was asked to determine whether a large volume of admissions made by Jason Manuel Ghiller to undercover Victoria Police operatives during a covert operation in the first half of 2000 (the B Series recordings) were admissible against him at his forthcoming trial on a broad presentment of offences arising from robberies and related violence committed in 1991–1994 (the "Pigout" robberies) and other incidents (see [2], [29], [56], [112], [115]).

The factual background: between 1991 and 1994 Ghiller (then aged 16–18) is alleged to have participated with his uncle Bandali Debs in a run of 28 armed robberies of 'soft targets' and several violent episodes including attempted murders (the Pigout robberies and associated offences) (see [29], [35], [59], [69], [72]). There was then a long investigatory hiatus. In 1998 two police officers were murdered (Cochranes Road), prompting intensive inquiries. By late 1999 police instituted electronic surveillance on several people including Ghiller and, in early 2000, initiated a covert operation to build a relationship with Ghiller and to obtain information. The operation involved undercover operatives (notably 'Gary' McKenzie) who developed a relationship with Ghiller and engaged in staged role‑playing of serious criminality (fake burglaries, kidnaps, rehearsals of 'big jobs') during April to July 2000 (see [88], [99], [106], [145], [148]). Over that period recordings were made (B1–B56) capturing Ghiller discussing his past offending and participating in simulated criminal plans (see [112], [115], [128]). Ghiller was arrested on 31 July 2000 after a final meeting (see [120], [124], [128]). The prosecution sought to admit the covert recordings at trial; the defence argued they were involuntary, unreliable and should be excluded as unfair or contrary to public policy (see [151], [172], [181], [196]).
Cummins J's ruling was that the covert recordings and admissions were admissible. The judge found the admissions voluntary, reliable (with corroboration available), and that public policy did not require exclusion because the operation did not involve police committing the offences, did not induce Ghiller into committing crimes for the purpose of charging him, and was a properly controlled investigative exercise into very serious unsolved offences (see [160], [163], [175], [181], [184], [206]–[215], [218]).
The decision turns on three linked legal questions: voluntariness, unfairness (discretion to exclude), and public policy.
Voluntariness. The controlling legal test is whether the statements were made in the exercise of free choice or whether the accused’s will was overborne (see authorities applied at [157]). Cummins J applied the test and focused on the factual indicators. He emphasised that Ghiller was not in custody ([154]); the recordings showed him speaking with enthusiasm, initiative and on equal footing with the operatives ([160], [163]). There was no evidence that he was menaced, threatened, or overborne; indeed the accused did not give evidence claiming his will was overborne ([169]). On that basis the judge was "affirmatively satisfied" that the accused acted and spoke voluntarily in the relevant period ([160], [163], [175]).
Unfairness/Discretion to exclude. Even if voluntary, the court may exclude evidence if its reception would be unfair or render the trial unfair. Cummins J applied authorities such as R v Swaffield and others (see [181]). He rejected the defence submission that the role-playing and cultivation of trust produced an unfair forensic disadvantage. The judge accepted that there was a forensic disadvantage but held that disadvantage does not equate to unfairness warranting exclusion. He noted that the covert recordings were not unreliable, and that there was extrinsic corroboration for the admissions ([184], [187], [190]).
Public policy. The defence argued that police conduct in creating a false scenario and role-playing serious crimes to 'activate' dormant criminal tendencies offended public policy and required exclusion. The judge analysed five key matters relevant to the public policy question: (i) Ghiller was a free citizen; (ii) he acted and spoke voluntarily and enthusiastically; (iii) the operation involved no actual criminal conduct by police (it was artificial role-play); (iv) it was conducted in controlled circumstances and was not dangerous; and (v) police did not encourage Ghiller into conduct for the purpose of arresting and charging him ([206]). Given these facts, and given the proper investigative purpose (to solve serious robberies and attempted murders), Cummins J concluded that public policy did not require exclusion and that admitting the material was consonant with public policy ([209]–[215]).
The judge therefore admitted the recordings and the admissions they contained (final order at [218]).
Before this ruling the law in Australia (and in Victoria) provided that involuntary confessions, or admissions produced by improper police tactics, should be excluded. The governing principles include the voluntariness doctrine (whether the accused’s will was overborne) and the discretionary exclusion of improperly obtained evidence if admission would make the trial unfair. Authorities such as McDermott v R, R v Lee, R v Collins outline the voluntariness test; R v Swaffield and related authority guide unfairness/discretion and public policy considerations (see [157], [181], [193]).
DPP v Ghiller applies these established principles to a modern, extended undercover operation involving elaborate role-playing. The judgment affirms that undercover role‑playing per se does not make admissions involuntary or automatically trigger exclusion. The key factors remain custody status, coercion/overbearing, inducement to commit offences, whether police themselves committed crimes, the controlled nature of the operation, and the investigative purpose. Where the accused is a free citizen who voluntarily engages in conversation and initiative-taking, the admissions will generally be treated as voluntary and admissible, subject to fairness/public-policy scrutiny. This ruling reinforces that undercover operations can produce admissible evidence where they stop short of unlawful or procuring criminal acts and where safeguards exist.
Paragraph 115 (quotation of McKenzie): "I then offered Ghiller some part-time work... Ghiller stated that he would be prepared to do any work." Plain English: The undercover operative offered Ghiller a job that could be illegal; Ghiller agreed he would do that kind of work. This shows willingness and initiative on Ghiller’s part, a fact central to voluntariness ([115]).
Paragraph 128 (final tape at arrest): the undercover operative reveals the set-up and that everything had been taped. Plain English: At the moment of arrest, operatives identified themselves as police and told Ghiller his conversations were recorded. The judge held that this later disclosure did not retroactively taint earlier admissions made voluntarily ([128], [133]).
Paragraph 163: "the accused... was a free citizen... speaking and acting enthusiastically and often of his own sole initiative." Plain English: Ghiller was not detained or coerced; the recordings show him willingly and actively participating; his will was not overborne ([163]).
Paragraph 206: the five factors bearing on public policy. Plain English: the judge listed five reasons why public policy did not require exclusion, Ghiller was free, voluntary, enthusiastic, the undercover scenarios involved no real criminal acts by police, and police did not induce him to commit crimes for a charge ([206]).
Paragraph 215: "It is consonant with public policy to admit it." Plain English: Given the facts and controls, admitting the covert recordings fits with public policy and should not be barred ([215]).
This ruling is most directly applied where:
An accused, not in custody, makes admissions to undercover police during an extended covert operation and the defence alleges involuntariness or improper inducement ([154], [157], [160]).
The undercover operation engages in staged or role-played criminality (simulated burglaries, kidnaps, rehearsals) but does not involve police actually committing the offences or actively procuring the accused to commit offences that they would otherwise not commit ([145], [209], [212]).
The prosecution can point to features indicating voluntariness: the accused’s enthusiastic spontaneity on recordings, absence of threats, lack of evidence that the accused’s will was overborne, and potential extrinsic corroboration of admissions ([160], [163], [169], [184]).
The operation is targeted at solving very serious outstanding crime and the police did not use simulated activity to fabricate a chargeable offence against the target ([103], [206]).
Conversely, the precedent will be distinguishable where the undercover conduct amounts to police-initiated criminality, active inducement of the accused to commit new offences for charging purposes, or where the accused is effectively in custody or subjected to coercive pressure such that their will was overborne.
This ruling itself applies and explains established High Court and Victorian authorities on voluntariness and unfairness (McDermott, Lee, Collins, Swaffield, Ridgeway, and Victorian decisions). Cummins J expressly applied and considered those authorities (notably at [157], [181], [193]). The decision is a useful illustration at trial-preparation stage of how sustained undercover role‑playing is to be assessed: focus on custody, coercion, inducement, police criminality, control and investigative purpose. Future courts considering admissibility of undercover recordings will look to this decision for its careful articulation of the five public-policy factors ([206]) and its insistence that role‑playing per se is not disqualifying ([209]–[215]). Practitioners should therefore expect courts to engage in close fact-sensitive analysis rather than categorical rules where undercover tactics are involved.
Borderline inducement. While Cummins J found no inducement here, close cases remain where operatives may take an active role in procuring criminality (not mere role‑play), the exact line between permitted role‑playing and impermissible inducement remains fact-sensitive and will require future judicial clarification in borderline cases.
Control and safety assurances. The judge emphasised the operation was 'controlled' and 'not dangerous' ([209]). What particular controls and safeguards are legally sufficient or necessary to satisfy public policy concerns is not exhaustively defined in this ruling.
Custody-like circumstances. The decision stresses that Ghiller was not in custody ([154]). Cases in which undercover operations so constrain or manipulate an accused that custody-like conditions arise (e.g. deception combined with incommunicado isolation) were not explored here and would raise distinct voluntariness issues.
Retraction/pollution by later inducement. Cummins J accepted the final 'set-up' disclosure did not pollute earlier admissions ([128], [133]). Where a later event or inducement occurs closer in time to antecedent admissions, the doctrine of 'pollution' may require more nuanced analysis.
Policy limits on staging particularly dangerous simulations. The decision accepts dramatic role‑playing so long as police do not themselves commit crimes, but it leaves unresolved whether staging very violent or dangerous simulations that put participants at risk could produce public-policy exclusion even absent police criminality.
Practitioners should therefore approach covert operations and subsequent admissibility challenges mindful of these open points: ensure meticulous control and documentation of undercover methods; avoid any procurement of new offences; preserve opportunities for the subject to act freely; and maintain corroborative evidence where possible.

Jason: "I can't remember but, but this was years ago, a couple of days after we burnt the cunt." Gary: "Yeh." Jason: "At fucken Fountain Gate Shopping Centre, we put it at the back where despatch is, Safeway."
"In September 1999 a decision was made to investigate the possible involvement of Jason Ghiller and Bandali Debs in the Pigout series of robberies."
No doubt that was expressed in that way for reasons both of relevance and to avoid prejudice to the accused Mr Ghiller by not associating him in the statement with the murders of the two police officers, Sergeant Silk and Senior Constable Miller. However, as the Detective Sergeant readily stated in cross-examination at the committal at p.1408 on 10 September 2001, in fact Mr Ghiller was one of three persons, being Mr Ghiller, Mr Debs and Mr Roberts, who were the subject of Operation Solly and which was established, as the Detective Sergeant stated in cross-examination below, to investigate Messrs Debs, Roberts and Ghiller in relation to the murders of Sergeant Silk and Senior Constable Miller.
"The aim of the operation was to establish whether he was involved - the predominant aim was to establish, one, whether Mr Ghiller was involved in the murders of Sergeant Silk and Senior Constable Miller and two, to try and establish contact with either Mr Debs or Jason Roberts."
"I then offered Ghiller some part-time work. Ghiller asked whether it would be legal or illegal. I stated it wouldn't be all legal. Ghiller stated that he would be prepared to do any work." (D.2974).
In evidence before me Mr Gary McKenzie stated the response of Mr Ghiller to being asked "if he was interested in doing any part-time work for me" was that he "gratefully agreed" (T.41).
"On Sunday the 3rd of July 2000 I sent a text message on my mobile phone to Jason Ghiller confirming that I pick up Ghiller at 10.00 a.m. the following day. Ghiller returned the message to me stating, 'No probs'. On Monday the 31st of July 2000 I received a text message from Ghiller asking how long I was going to be. I replied with, 'Three minutes'. At approximately 9.54 a.m. Covert Operative Billy and Covert Operative Pat and I attended at 12 Pinnacle Way, Hampton Park. Jason Ghiller was waiting in his front yard. At this stage I was driving, C.O. Pat was in the front passenger seat and C.O. Billy was in the rear driver's side seat. Ghiller then got into the rear passenger seat of the vehicle. I then drove to the city. During this time we had general conversation."
**"**At approximately 10.45 a.m. we attended at the St Kilda Road police complex, where members of the Lorimer Taskforce arrested Ghiller."
Gary: "Up your arse a couple of times... (inaudible)...(humming). You bloody ripper. Maybe he's got everything ready." Jason: "Fuckin', what are those cunts doing?" Gary: "Jase, I've got some bad news for you, buddy. You were right. It's a set-up, mate, and we're from the government. What I'm going to get you to do, cooperate with these blokes. They are from the Lorimer Taskforce, mate, OK? It's your last hope. You'll be given what you want. If you give them what you want, everything will be fine. Everything that you've told me has been taped. We're just doing our job, and that's it, mate, all right? As long as you understand that, just help them out, mate."
Mr Ghiller's company and the numerous decent citizens who were subject to the Pigout robberies, and by other extrinsic evidence and material.
**"**The right of the citizen and the working of the constitution, in the sense which I have described, have upon the whole, since the fall of the Stuart dynasty, received from the judiciary - and they appear to me still the demand of it - a constant and most watchful respect. There is no greater danger of usurpation than that which proceeds little by little, under cover of rules of procedure, and at the instance of judges themselves."

Court ruled that the covert recordings (B Series) and admissions made by the accused are admissible. The judge found the admissions voluntary, reliable, and not unfairly obtained; public policy did not require their exclusion (see [160], [163], [175], [181], [184], [206]–[215], [218]).
