The legislative background
4Prior to dealing with the parties' submissions it is convenient to set out the relevant State and Commonwealth legislation.
5Section 25 of the Drug Act created the offence of supplying a prohibited drug. At the time of the alleged offence it was in the following terms:
"25(1) A person who supplies, or who knowingly takes part in the supply of, a prohibited drug is guilty of an offence.
(1A) A person of or above the age of 18 years who supplies, or who knowingly takes part in the supply of, a prohibited drug (other than cannabis leaf) to a person under the age of 16 years is guilty of an offence.
(2) A person who supplies, or who knowingly takes part in the supply of, an amount of a prohibited drug which is not less than the commercial quantity applicable to the prohibited drug is guilty of an offence.
(2A) A person of or above the age of 18 years who supplies, or who knowingly takes part in the supply of, an amount of a prohibited drug (other than cannabis leaf) which is not less than the commercial quantity applicable to the prohibited drug to a person under the age of 16 years is guilty of an offence.
(2B) Where, on the trial of a person for an offence under subsection (1A) or (2A), the jury are satisfied that the person charged had, at the time the offence is alleged to have been committed, reasonable cause to believe, and did in fact believe, that the person to whom the prohibited drug was supplied was of or above the age of 16 years, they may acquit the person of the offence charged and find the person guilty of an offence under subsection (1) or (2), respectively, and the person is liable to punishment accordingly.
(2C) A person of or above the age of 18 years who procures a person under the age of 16 years to supply, or take part in the supply of, a prohibited drug (other than cannabis leaf) to another person is guilty of an offence.
(2D) A person of or above the age of 18 years who procures a person under the age of 16 years to supply, or take part in the supply of, an amount of a prohibited drug (other than cannabis leaf) which is not less than the commercial quantity applicable to the prohibited drug is guilty of an offence.
(2E) It is a defence to a prosecution for an offence under subsection (2C) or (2D) if the defendant establishes that the defendant had, at the time the offence is alleged to have been committed, reasonable cause to believe, and did in fact believe, that the person who was procured to supply, or take part in the supply of, the prohibited drug was of or above the age of 16 years.
(3) Where, on the trial of a person for an offence under subsection (2) or (2D), the jury are not satisfied that the amount of prohibited drug involved is equal to or more than the commercial quantity applicable to the prohibited drug, they may acquit the person of the offence charged and find the person guilty of an offence under subsection (1) or (2C), respectively, and the person shall be liable to punishment accordingly.
(4) Nothing in this section renders unlawful the supply of a prohibited drug by:
(a) a person licensed or authorised to do so under the Poisons Act 1996, or
(b) a person acting in accordance with an authority granted by the Secretary of the Department of Health where the Secretary is satisfied that the supply of the prohibited drug is for the purpose of scientific research, instruction, analysis or study, or
(c) a person acting in accordance with a direction given by the Commissioner of Police under section 39RA,
or renders unlawful the taking part by any other person in the supply of a prohibited drug by a person to whom paragraph (a), (b) or (c) applies.
(5) Nothing in this section renders unlawful the administration of a prohibited drug to a person being cared for by another person in the circumstances described in section 10 (2) (d)."
6Section 29 of the Drug Act sets out circumstances where possession is taken to be possession for supply. It provides as follows:
"29 A person who has in his or her possession an amount of a prohibited drug which is not less than the traffickable quantity of the prohibited drug shall, for the purposes of this Division, be deemed to have the prohibited drug in his or her possession for supply, unless:
(a) the person proves that he or she had the prohibited drug in his or her possession otherwise than for supply, or
(b) except where the prohibited drug is prepared opium, cannabis leaf, cannabis oil, cannabis resin, heroin or 6-monoacetylmorphine or any other acetylated derivatives of morphine, the person proves that he or she obtained possession of the prohibited drug on and in accordance with the prescription of a medical practitioner, nurse practitioner, midwife practitioner, dentist or veterinary practitioner."
7It should be noted that a traffickable quantity for the drug in question is 3 grams.
8"Supply" is defined in s 3 of the Drug Act as follows:
"supply includes sell and distribute, and also includes agreeing to supply, or offering to supply, or keeping or having in possession for supply, or sending, forwarding, delivering or receiving for supply, or authorising, directing, causing, suffering, permitting or attempting any of those acts or things."
9Section 4 of the Drug Act deals with admixtures. It provides as follows:
"4 In this Act, a reference to a prohibited drug includes a reference to any preparation, admixture, extract or other substance containing any proportion of the prohibited drug."
10It was not disputed that the effect of s 4 of the Drug Act was that it was not necessary for the prosecution to prove the precise amount of the particular prohibited drug contained in any substance which is the subject of the charge, including for the purpose of the deeming provision in s 29: R v R2 (1990) 19 NSWLR 513 at 514-515.
11Section 32 of the Drug Act provides that the maximum penalty for an offence under s 25(1) is a fine of 2,000 penalty units or imprisonment for a term of 15 years, or both.
12The offence of possession of a prohibited drug is dealt with in s 10 of the Drug Act. It provides as follows:
"10(1) A person who has a prohibited drug in his or her possession is guilty of an offence.
(2) Nothing in this section renders unlawful the possession of a prohibited drug by:
(a) a person licensed or authorised to have possession of the prohibited drug under the Poisons Act 1966,
(b) a person acting in accordance with an authority granted by the Secretary of the Department of Health where the Secretary is satisfied that the possession of the prohibited drug is for the purpose of scientific research, instruction, analysis or study,
(b1) a person acting in accordance with a direction given by the Commissioner of Police under section 39RA,
(c) a person for or to whom the prohibited drug has been lawfully prescribed or supplied, or
(d) a person who:
(i) has the care of, or is assisting in the care of, another person for or to whom the prohibited drug has been lawfully prescribed or supplied, and
(ii) has the prohibited drug in his or her possession for the sole purpose of administering, or assisting in the self-administration of, the prohibited drug to the other person in accordance with the prescription or supply."
13Section 9 of the Drug Act provides that prosecutions for offences of possession shall be dealt with summarily in the Local Court. Section 21 provides that the penalty for an offence under the Division that includes s 10 is a fine of 20 penalty units or imprisonment for 2 years, or both.
14The relevant Commonwealth legislation is Pt 9.1 of the Criminal Code entitled "Serious Drug Offence". At the relevant time, s 300.1 of the Criminal Code set out the purposes of the Part as follows:
"300.1(1) The purpose of this Part is to create offences relating to drug trafficking and to give effect to the United Nations Contravention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, done at Vienna on 20 December 1988.
(2) Subsection (1) does not limit the legislative powers of the Parliament in relation to this Part."
15Section 300.4 deals with the concurrent operation of State and Territory laws. It provides as follows:
"300.4(1) This Part is not intended to exclude or limit the concurrent operation of any law of a State or Territory.
(2) Without limiting subsection (1), this part is not intended to exclude or limit the concurrent operation of a law of a State or Territory that makes:
(a) an act or omission that is an offence against a provision of this Part; or
(b) a similar act or omission;
an offence against the law of the State or Territory.
(3) Subsection (2) applies even if the law of the State or Territory does any one or more of the following:
(a) provides for a penalty for the offence that differs from the penalty provided for in this Part;
(b) provides for a fault element in relation to the offence that differs from the fault elements applicable to the offence under this Part;
(c) provides for a defence in relation to the offence that differs from the defences applicable to the offence under this Part."
16Section 300.2 provides that a trafficable quantity of a controlled drug is a quantity not less than the quantity specified as a trafficable quantity in Division 314, under regulations or in a determination. At the time, the relevant quantities of controlled drugs were set out in s 314.1. Section 314.1(2) stated that a substance is a controlled drug if the substance is a stereoisomer. The affidavit supporting the notice of motion before Freeman DCJ stated that Dexamphetamine is a stereoisomer of Amphetamine. Amphetamine is listed as a controlled drug under s 314.1, the trafficable quantity being 2 grams.
17Division 302 of Pt 9.1 deals with trafficking in controlled drugs. Section 302.1 defines "traffics" as follows:
"302.1(1) For the purposes of this Part, a person traffics in a substance if:
(a) the person sells the substance; or
(b) the person prepares the substance for supply with the intention of selling any of it or believing that another person intends to sell any of it; or
(c) the person transports the substance with the intention of selling any of it or believing that another person intends to sell any of it; or
(d) the person guards or conceals the substance with the intention of selling any of it or assisting another person to sell any of it; or
(e) the person possesses the substance with the intention of selling any of it.
(2) For the purposes of paragraph (1)(b), preparing a substance for supply includes packaging the substance or separating the substance into discrete units."
18The word "sell" is defined in s 300.2 to include barter or exchange, or agree to sell. As such, it should be noted that the definition of "traffics" does not include gratuitous supply.
19Section 302.4 creates the offence of trafficking controlled drugs. It provides as follows:
"302.4(1) A person commits an offence if:
(a) the person traffics in a substance; and
(b) the substance is a controlled drug.
Penalty: Imprisonment for 10 years or 2,000 penalty units, or both.
(2) The fault element for paragraph (1)(b) is recklessness."
20Section 302.5 creates a presumption in respect of trafficking where a person has the controlled drug in his or her possession. It provides as follows:
"302.5(1) For the purposes of proving an offence against this Division, if a person has:
(a) prepared a trafficable quantity of a substance for supply; or
(b) transported a trafficable quantity of a substance; or
(c) guarded or concealed a trafficable quantity of a substance; or
(d) possessed a trafficable quantity of a substance;
the person is taken to have had the necessary intention or belief concerning the sale of the substance to have been trafficking in the substance.
(2) Subsection (1) does not apply if the person proves that he or she had neither that intention not belief."
21Section 308.1 deals with the offence of possessing controlled drugs. It provides as follows:
"308.1(1) A person commits an offence if:
(a) the person possesses a substance; and
(b) the substance is a controlled drug.
Penalty: Imprisonment for 2 years or 400 penalty units, or both.
(2) The fault element for paragraph (1)(b) is recklessness.
(3) If:
(a) a person is charged with, or convicted of, an offence against subsection (1); and
(b) the offence is alleged to have been, or was, committed in a State or Territory;
the person may be tried, punished or otherwise dealt with as if the offence were an offence against the law of the State or Territory that involved the possession or use of a controlled drug (however described).
Note: Subsection (3) allows for drug users to be diverted from the criminal justice system to receive the same education, treatment and support that is available in relation to drug offences under State and Territory laws.
(4) However, a person punished under subsection (3) must not be:
(a) sentenced to a period of imprisonment that exceeds the period set out in subsection (1); or
(b) fined an amount that exceeds the amount set out in subsection (1).
(5) Subsection (3) does not limit:
(a) Part 1B of the Crimes Act 1914; or
(b) section 68 or 79 of the Judiciary Act 1903; or
(c) any other law that provides for a law of a State or Territory to apply in relation to the exercise of federal jurisdiction."
22In considering the issues raised in the appeal the provisions of s 4C of the Crimes Act 1914 (Cth) are also relevant. This section provides as follows:
"4C(1) Where an act or omission constitutes an offence:
(a) under 2 or more laws of the Commonwealth; or
(b) both under a law of the Commonwealth and at common law;
the offender shall, unless the contrary intention appears, be liable to be prosecuted and punished under either or any of those laws of the Commonwealth or at common law, but shall not be liable to be punished twice for the same act or omission.
(2) Where an act or omission constitutes an offence under both:
(a) a law of the Commonwealth and a law of the State; or
(b) a law of the Commonwealth and a law of a Territory;
and the offender has been punished for that offence under the law of the State or the law of the Territory, as the case may be, the offender shall not be liable to be punished for the offence under the law of the Commonwealth.
(3) Where an act or omission constitutes an offence against a law of a Territory, the validity of that law is not affected merely because the act or omission also constitutes an offence against a law of the Commonwealth."
23As I indicated, Pt 9.1 was passed to give effect to the United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances (Convention). Article 3 of the Convention so far as is relevant provides as follows:
"1. Each Party shall adopt such measures as may be necessary to establish as criminal offences under its domestic law, when committed intentionally:
(a)(i) The production, manufacture, extraction, preparation, offering, offering for sale, distribution, sale, delivery on any terms whatsoever, brokerage, dispatch, dispatch in transit, transport, importation or exportation of any narcotic drug or any psychotropic substance contrary to the provisions of the 1961 Convention, the 1961 Convention as amended or the 1971 Convention."
24It should be noted that the Convention did not preclude legislating in respect of gratuitous supply.
25The introduction of Pt 9.1 of the Criminal Code was preceded by a Report of the Model Criminal Code Officers Committee (Committee) dated October 1998. Chapter 6 of the Report dealt with serious drug offences. It should be noted that the Report made it clear that the views expressed did not necessarily represent the views of the Standing Committee of Attorneys-General.
26The introduction to Ch 6 of the Report contained the following statement:
"The central theme of this chapter is that the serious offences should focus on individuals who make a business out of drug trafficking. The report proposes three levels of liability, according to whether the offender traffics a large commercial quantity, a commercial quantity or in any quantity at all. Whilst quantitative measures of liability and presumptions of guilt bases on possession of trafficable quantities are common to many jurisdictions, they are remarkable for their absence of any semblance or uniformity. The Committee proposes a more unified approach. It is a primary object of the report to stimulate debate on the appropriateness of existing quantitative measures of liability. This issue has been largely ignored in previous reviews, yet it is a major determinant of an offenders level of criminality and subsequent punishment. The report investigates the rationale for the existing table of drug quantities and seeks to develop a more appropriate model suitable for all State, Territories and the Commonwealth."
27The Report emphasised the desirability of uniform State and Territory legislation on this issue:
"There is a defensible case for a considerable degree of variation among States in some aspects of health and regulatory legislation. It is obvious, however, that uniformity is essential in those elements of health and regulatory legislation which deal with matters of interstate or international concern. The controls over wholesale and retail distribution and the essential vocabulary of control - the schedules, standards and nomenclature of drug law - all fall within the realm where the need for uniformity is undeniable. The same considerations mandate uniformity in legislation directed against the illicit commercial traffic in psychoactive drugs.
The illicit drug distribution system operates Australia wide and internationally. Australia has undertaken international obligations requiring severe criminal measures against individuals who play a significant commercial role in the organised traffic in drugs. Though there is room for variation in legislative measures directed to the control of use and minimisation of harm to users, the arguments for uniformity in measures directed against commercial exploitation in the illicit market are clear and compelling."
28The Report stated that as the object of the offences proposed by the Chapter was to strike out illicit traders rather than users, gratuitous transfers were excluded. The Committee made the following comments:
"... In this respect the draft is different from legislation in most Australian jurisdictions, which prohibit sale or supply. The draft follows instead the Victorian Drugs Poisons and Controlled Substances Act 1981, which excludes gratuitous transfers from the scope of trafficking. For the same reason, Chapter 6 does not include gratuitous administration of controlled drugs to another in the trafficking offence.
Though the general principle is clear, there is an obvious need for exceptions when particular circumstances make gratuitous transfers equivalent in the scale of wrongdoing to trafficking. Gifts or administration of controlled drugs to children are singled out as especially serious offences in some jurisdictions. Chapter 6 accordingly makes supply to a child an offence equivalent to trafficking in some circumstances. Offences involving children are distinguished from trafficking however. Corruption of the young belongs to a different order of wrongdoing from illicit trading and the offences involving supply to minors are the subject of a separate set of provisions in the Code. Whilst they are extremely serious, discretion and humanity are essential in their administration. A significant proportion of those who supply minors will be friends and associates of similar age, who are not engaged in commercial trafficking."(Citation omitted)
29The Report highlighted the difficulty with the concept of supply in the following terms:
"The complexity of the law on the meaning of supply is a cogent reason for avoiding reliance on the concept if an alternative can be found. There is an additional consideration. Since 'supply' does not include the return or delivery of drugs to their owner, a prohibition against supply is likely to obscure the obvious possibility that the individual who returned the drugs is guilty as an accomplice who provided storage or other facilities: see Carey (1990) 50 A Crim R 163 at 168-169.
It is unnecessary to include prohibitions against supply in trafficking legislation. There are two sets of circumstances in which a prohibition against supply might be thought to have a role in a scheme of prohibitions aimed at commercial trafficking or other major drug crime. The first of these involves commercially motivated gifts to minors. These are the subject of specific prohibition in section 6.4.4 - Supply of drugs to a child. The second area of possible application arises when a person provides storage facilities, transport or other services which involve a transfer of possession of controlled drugs to that person without sale. Such cases are covered, however, by the general provisions on accomplices in Division 11 of Chapter 2 of the Model Criminal Code or in specific prohibitions in this Chapter."
30Notwithstanding the statement by the Committee of the desirability of uniform legislation, the Explanatory Memorandum accompanying the introduction of the Law and Justice Legislation Amendment (Serious Drug Offences and Other Measures) Bill 2005 stated that State legislation would continue to operate alongside the Commonwealth legislation:
"... Existing State and Territory regulatory schemes will continue to operate, and it will be a defence to the offences in the Bill if the relevant conduct is justified or excused under a law of the Commonwealth or a State or Territory.
Overlapping State and Territory drug offences will also continue to operate alongside the offences in Part 9.1 of the Criminal Code. This approach is consistent with the approach taken in other areas of criminal law, such as terrorism, fraud, computer crime, money laundering and sexual servitude. It is intended that drug offences will continue to be investigated in accordance with the established division of responsibility between federal and State and Territory law enforcement agencies. The Bill preserves the existing powers of law enforcement officers, including Customs officials and the Australian Federal Police, in relation to serious drugs offences."
31However, the Explanatory Memorandum did emphasise that it was intended that gratuitous transfers be excluded. In explaining the effect of s 302.1 the Explanatory Memorandum stated:
"Where trafficking is by possession, the person themselves must be shown to have the intention to sell: the more restrictive fault element in this kind of trafficking reflects the more passible and preliminary nature of the conduct of the accused who merely possesses a controlled drug."
32This was again emphasised in dealing with the manner in which the presumption contained in s 302.5 could be rebutted:
"If the prosecution shows that there is a trafficable quantity of controlled drug involved in the offence and engages the trafficable quantity presumption, proposed subsection 302.5(2) makes available to the defendant a defence of absence of commercial purposes. If the defendant can prove on the balance of probabilities that he or she did not have both the relevant intention and belief, the defendant would then only be guilty of a base possession offence under proposed section 308.1, rather than any of the commercially motivated trafficking offences in proposed Division 302."
33The Second Reading Speech also stated that it was intended that the legislation would operate alongside State and Territory legislation, although the Attorney-General emphasised the desirability for uniform legislation in this area. The relevant remarks were as follow:
"Our existing offences are mainly focused on preventing illicit drugs from crossing Australia's border. The new offences will also apply to drug dealings within Australia.
To that extent, they will operate alongside state and territory offences to give more flexibility to law enforcement agencies. This approach will ensure there are no gaps between federal and state laws that can be exploited by drug cartels.
...
One of the main objectives of this bill is to increase the uniformity of drug laws throughout Australia by implementing model drug offences. The next important step will be to achieve nationally consistent lists of drugs that the model offences can apply, and the quantities that trigger the different penalty tiers under the model offences."
