Should the Unlawfully Obtained Evidence be Admitted?
32As the execution of the search warrant was unlawful, it is necessary to determine whether, having regard to section 90 and/or 138 of the Evidence Act 1995, the evidence should be admitted.
Section 90 provides:
90. In a criminal proceeding, the court may refuse to admit evidence of an admission, or refuse to admit the evidence to prove a particular fact, if:
(a)the evidence is adduced by the prosecution, and
(b)having regard to the circumstances in which the admission was made, it would be unfair to a defendant to use the evidence.
Section 90 is concerned only with admissions. Section 138 has a broader application. It is convenient to consider first s 138.
Section 138 provides:
(1) Evidence that was obtained:
(a) improperly or in contravention of an Australian law, or
(b) in consequence of an impropriety or of a contravention of an Australian law,
is not to be admitted unless the desirability of admitting the evidence outweighs the undesirability of admitting evidence that has been obtained in the way in which the evidence was obtained.
...
(3) Without limiting the matters that the court may take into account under subsection (1), it is to take into account:
(a) the probative value of the evidence, and
(b) the importance of the evidence in the proceeding, and
(c) the nature of the relevant offence, cause of action or defence and the nature of the subject-matter of the proceeding, and
(d) the gravity of the impropriety or contravention, and
(e) whether the impropriety or contravention was deliberate or reckless, and
(f) whether the impropriety or contravention was contrary to or inconsistent with a right of a person recognised by the International Covenant on Civil and Political Rights , and
(g) whether any other proceeding (whether or not in a court) has been or is likely to be taken in relation to the impropriety or contravention, and
(h) the difficulty (if any) of obtaining the evidence without impropriety or contravention of an Australian law.
(emphasis added)
33In this case, critical evidence concerning possession by the accused of the drugs on 25 November 2006 was obtained in contravention of LEPRA. Other important evidence (such as statements made by the accused in an electronically recorded interview when he was confronted with the search warrant findings) was obtained "in consequence of a contravention of Australian law" in that the evidence "can be directly linked to the impropriety (albeit through a process involving several steps)": Application of Lee [2009] ACTSC 98 per Penfold J. at [31].
34Prima facie, the evidence is inadmissible. The onus is on the prosecution to establish that the desirability of admitting the evidence outweighs the undesirability of admitting evidence obtained in the way in which the evidence was obtained: Parker v Comptroller-General of Customs [2009] HCA 7 at [28], DPP v Tamcelik [2012] NSWSC 1008.
35The Court is required to consider the matters set out in s 138(3) and any other relevant matter. As to the considerations set out in s 138(3)(a) and (b), the unlawfully obtained evidence is of high probative value and critical importance to the conduct of the prosecution. As to the consideration in (c), the relevant offence is moderately serious. However, a deemed supply of a significant (but not large) amount of a prohibited drug where the prosecution relies upon one instance of possession is not one of the most serious offences on the criminal calendar. As to the considerations in s 138(3)(d) and (e), those executing the warrant did not act mala fides. At the time when the warrant was executed, there was a widespread misunderstanding that a warrant could be "covertly executed". Following the decision in Ballis, LEPRA was amended to legitimise the practice of the "covert execution" of warrants. In R v Helmhout [2001] NSWCCA 372, at [21] Hulme J. held that, in s 138(3)(e), "reckless" involved, at least, some advertence to the possibility of a breach of a relevant law and a conscious decision to proceed regardless. In the context of the practice at the time, the contravention that occurred in this case should be characterised neither as "deliberate" nor as "reckless". Nevertheless, the conduct was a serious intrusion upon the rights of the accused: R v Sibraa [2012] NSWCCA 19 per Hulme J at [18]. The considerations referred to in s 138(3)(f), (g) and (h) have no application in this case.
36Although the considerations referred to in section 138(3) generally favour the prosecution, the question remains whether the prosecution has discharged the onus of showing that the desirability of admitting the evidence outweighs the undesirability of admitting evidence that has been obtained in the way in which the evidence was obtained. In this case, the alleged offence occurred more than six years ago. All the critical evidence in the NSW proceedings is tainted by unlawfulness that involved "a serious intrusion upon the rights of the accused". The evidence supporting the NSW proceedings formed part of the evidence in the Queensland proceedings and, inferentially, was taken into account when the Queensland sentence was formulated. The accused has served his non-parole period in Queensland. In the NSW proceedings, the prosecution seeks to secure a conviction but it does not seek to secure an additional penalty. The prosecution has failed to establish that there is a substantial public interest or other relevant "desirability" militating in favour of admitting the unlawfully obtained evidence.
