Relevant principles concerning the Rule against Duplicity
4In S v The Queen [1989] HCA 66; (1989) 168 CLR 266 Gaudron and McHugh JJ at [5]-[6] explained the basis of the rule against duplicity as:
5. The rule against duplicitous counts in an indictment originated as early as the seventeenth century... It may be... that the rule grew out of the strict formalities associated with criminal pleadings at a time when the difference between misdemeanour and felony was the difference between life and death. However, the rule against duplicitous counts has, for a very long time, rested on other considerations. One important consideration is the orderly administration of criminal justice. There are a number of aspects to this consideration: a court must know what charge it is entertaining in order to ensure that evidence is properly admitted, and in order to instruct the jury properly as to the law to be applied; in the event of conviction, a court must know the offence for which the defendant is to be punished; and the record must show of what offence a person has been acquitted or convicted in order for that person to avail himself or herself, if the need should arise, of a plea of autrefois acquit or autrefois convict...
6. The rule against duplicitous counts has also long rested upon a basic consideration of fairness, namely, that an accused should know what case he or she has to meet. See, for example, R. v. Robe, at p 999 (p 994 of ER) where it was said "this is so general a charge, that it is impossible any man can prepare to defend himself on this prosecution ... ". See also R. v. Hollond, per Lord Kenyon C.J. at p 623 (p 348 of ER); R. v. North (1825) 6 Dowl & Ry 143, at p 146 (28 RR 538, at p 541); R. v. Morley, at pp 224-225 (p 654 of ER); and Cotterill v. Lempriere, per Lord Esher M.R. at p 639...
5In Chapman v R [2013] NSWCCA 91 Adamson J, with Hebden CJ at CL and Davies J agreeing, succinctly stated the object of the rule against duplicity to be that at [19]:
The object of the rule against duplicity has always been that there should be no uncertainty as to the offence charged: Chief Constable of Norfolk v Clayton [1983] 2 AC 473. The rule against duplicity prohibits a single count in an indictment charging a person with the commission of more than one offence: S v The Queen at 280-281 per Toohey J, citing Archbold, Pleading, Evidence and Practice in Criminal Cases, 43 ed (1988), page 46.
The Court said at [25] that this involves an analysis of:
25. The cases draw a distinction, for the purpose of determining whether a count in an indictment is bad for duplicity, between alternative factual bases of liability on the one hand and alternative legal formulations of liability based on the same or substantially the same facts: R v Cramp [1999] NSWCCA 324; 110 A Crim R 198 (Cramp) at [65] per Barr J, Sully and Ireland JJ agreeing.
6In Romeyko v Samuels (1972) 2 SASR 529; (1972) 19 FLR 322, Bray CJ said in the case of statutory offences that:
The true distinction, broadly speaking, it seems to me, is between a statute which penalises one or more acts, in which case, two or more offences are created, and a statute which penalises one act if it possesses one or more forbidden characteristics. In the latter case there is only one offence, whether the act under consideration in fact possesses one or several such characteristics.
7Of both binding and persuasive authority in the interpretation of the s 178BB, s 192G, s 55(a) and s 44(1)(a) offences in this matter is the decision of the New South Wales Court of Criminal Appeal in Giam v R [1999] NSWCCA 53; (1999) 104 A Crim R 416, where the Court (Spigelman CJ, with Abadee and Adams JJ agreeing), held that s 178BB created but a singular offence for "any statement... in a material particular". At [16]-[20] Spigelman CJ said:
16 It was submitted in this case, as it was in Walsh v Tattersall, that s8(b) of the Interpretations Act 1987 stating that the use of the singular will include the plural may be applicable in this case, so that the word "statement" in s178BB of the Crimes Act shall be understood to mean "statements". In my view that submission should not be accepted.
17 The first reason for that is this is a criminal statute and it should be construed strictly. The second reason is that the word immediately preceding the word "statement" is the word "any", which points to a degree of singularity. Thirdly, the conclusion is reinforced by the crucial sub-element of the same element in the section, namely the definition of the nature of the statement. The statement has to be a statement which a person knows to be false or misleading "in a material particular", or which is in fact false or misleading "in a material particular" and which is "made with reckless disregard as to whether it is true or false or misleading", again, "in a material particular".
18 The reference to the definite article in these crucial references to "material particularity" is such as to identify the fact that a single statement is being referred to on the proper construction of s178BB.
19 There is a category of cases in which a single statement can be constituted from more than one utterance or representation. Indeed, the second of the two statements in the charges under consideration in this case, namely whether or not a person had authority to enter into a contract, is characteristically a "statement" which can be so described. It is a "statement" which on many occasions is an inference to be drawn from a number of utterances and a course of conduct.
20 In Stanton v Abernathy (1990) 19 NSWLR 656 at 662 Gleeson CJ said:
"As King CJ observed in R v Traino (1987) 45 SASR 473 in the context of perjury, a number of utterances made on oath by an individual concerning a given subject may or may not, depending upon the circumstances, constitute a single false statement or a number of false statements or, of course, a number of statements some of which are false and some of which are not. Each false statement involves a separate crime of perjury. Considerations of commonsense and fairness enter into a judgment on the question of how many statements ought to be taken to have resulted from a number of utterances."
