8 The first question arises because Count 2 alleges that the accused engaged in transactions (plural), whereas s.122(2)(a) of the Confiscation Act provides that a person engaged in money laundering if the person engages in a (singular) transaction which involves the proceeds of crime.
9 An offence can be validly charged as being constituted by a continuous transaction, or a series of transactions, which occur between nominated dates. Further, such an offence can be validly charged notwithstanding that the offence itself could be committed by one single act out of the series of transactions alleged against the accused. For example, an accused can be validly charged with trafficking a drug of dependence "between dates", notwithstanding that the trafficking can be constituted by a number of separate transactions occurring between those dates. See R v Giretti;[6] R v Lao and Nguyen.[7]
10 If, on the other hand, as a matter of statutory construction the offence necessarily consists of only one transaction, it is impermissible to charge the offence in the plural. To do so is to charge an offence which is not known to law. An instance of such a charge was considered by Gaudron J and Gummow J to have occurred in the charge against the accused in Walsh v Tattersall.[8] The question is essentially one of statutory construction. In Walsh v Tattersall, the important consideration was whether the offence was described in the legislation as being constituted by a single transaction. See also R v Moussad.[9] Nevertheless even in such a case the offence may be charged as consisting of two or more transactions or events, each of which might, individually, constitute an offence under the relevant legislation. See Hyde v Mason.[10]
11 Section 122(2)(a) of the Confiscation Act provides that a person engages in money laundering if that person engages in a (singular) transaction. Thus on the face of it s.122(2)(a) would provide for an offence in respect of each individual transaction which involved the proceeds of crime.
12 However, the analysis of s.122 does not end there. It is s.122(1) which creates the statutory offence. It provides for an offence in respect of "a person who engages in money laundering". Similarly, s.122(2)(a) provides that that person "engages in money laundering" if the person "engages" in a transaction involving money which is the proceeds of crime. It is significant that the section employs the verb "engages". The act of engaging can be, and generally is, a continuous act. Equally, a transaction may, and often does, involve a number of acts which themselves constitute transactions. For example a transaction involving the purchase of an item may involve several constituent transactions, including entry into the contract of purchase, payment of the deposit, payment of a part payment, payment of the balance of a purchase price, and delivery of possession of the item.
13 The next aspect which must be noted about s.122(2) concerns its structure. Section 122(2)(a) provides that a person engages in money laundering "if and only if" the person engages in a transaction involving the proceeds of crime. Thus a person may only engage in money laundering if that person engages in a transaction involving the proceeds of crime. If the person does not engage in a transaction involving money which is the proceeds of crime, the person does not engage in money laundering. However, it does not follow that a person engages in more than one act of money laundering if the person engages in more than one transaction involving the proceeds of crime. As I have stated, a purchase involving the proceeds of crime may itself, strictly speaking, involve a number of transactions. It could not have been intended that the person who made that purchase was, under s.122(2)(a), guilty of some four or five separate offences of money laundering.
14 It is next important to note that s.122(2) may apply to a case where the crime, from which the relevant proceeds are derived, may be a continuing offence. Indeed, in the instant case, the proceeds of crime referred to in Count 2 are alleged to have been derived from the conspiracy (charged in Count 1), which itself is alleged to have occurred over a three and a half year period. In such a case, a large number of interrelated transactions may be effected with the proceeds which were progressively derived from that crime during the period in which it was committed. While one transaction with the proceeds of that crime may well constitute a single act of money laundering under s.122(2), it would produce a strange and indeed absurd result if each individual transaction involving the proceeds of that crime must be considered a discrete and separate offence and charged as such.
15 If s.122(2)(a) was construed so that each individual transaction - each purchase, deposit or transfer - involving the proceeds of a continuing crime was a discrete offence, such a construction would produce a multiplicity of charges which would not only be highly artificial, but could be quite unfair to an accused. Indeed such a result could occur in the present case. If each deposit, transfer, and purchase, was separately charged as a transaction under s.122(2)(a), each accused would stand charged with a multiplicity of interrelated offences which would not only be difficult to disentangle, but which would be well nigh impossible for a jury to consider separately from each other. The legislature could not have intended that s.122 would operate in such an artificial manner.
16 Each of those considerations are relevant to the proper construction of s.122(2)(a). As I have stated, a person is only guilty of money laundering if that person engages in a transaction involving money which is the proceeds of crime. However it does not necessarily follow that each time the person engages in a transaction involving money which is the proceeds of crime, that person commits a discrete offence which must be charged separately. Accordingly, I do consider that, as a matter of statutory construction, an offence may be charged under s 122(2)(a) of the Confiscation Act as constituted by more than one transaction.
Duplicity
17 The second question is whether Count 2 is bad in law for duplicity.
18 A count is duplicitous if it charges the accused with two or more separate offences.[11] If I am correct in concluding that, as a matter of construction, an offence under s.122(2)(a) of the Confiscation Act may be committed by two or more related transactions involving the proceeds of crime, then it must follow that Count 2 is not patently duplicitous. The question nonetheless arises whether Count 2 contains a latent duplicity. The answer to the question depends on the manner in which the Crown makes its case in respect of Count 2.
19 Where an offence may consist of two or more acts or transactions, each of which themselves may individually also constitute the commission of the offence, it is not duplicitous to charge the offence as one offence occurring between dates, if the various transactions constituting the charge essentially involved the one continuing transaction or enterprise.
20 Thus, in Director of Public Prosecutions v Merriman[12] Lord Diplock stated:
