[58] While s 31(1) permits more than one contravention of 'a provision' of Division 1 arising out of the same factual circumstances, to be charged as a single offence, it does not authorise contraventions of two or more of those provisions to be charged in the one offence. Here, the factual particulars provided in relation to the s 8 charge, could have been charged as separate offences, or as a single offence, consistently with s 31(1). The offence under s 10, however, may not be advanced as part of the one offence, given the provisions of s 31(2). This is confirmed by s 30, which deals with the circumstances in which alternative convictions may result in proceedings brought under the OHS Act. This is limited to offences brought under ss 8 and 9 and does not extend to s 10. Neither the provisions of the common law, nor general provisions such as s 23 of the Criminal Procedure Act , can be called in aid to avoid the operation of the express provisions made by the OHS Act as to these matters.
30 We do not agree with her Honour's conclusions as to the operation of the statutory scheme. As earlier stated, we are satisfied that the ordinary meaning conveyed by the text of s 31 permits the laying of alternative charges. There is no prohibition in s 31, either express or implied, against laying charges against a defendant in the alternative, as was found by Schmidt J. The fact that a defendant could be charged with the two offences separately does not preclude the offences being charged as alternatives in a single prosecution.
31 As earlier stated, s 30 is not directly relevant to the issue of whether alternative charges may be laid, and certainly does not limit the operation of s 31 in the manner suggested by Schmidt J.
32 Further, there are compelling practical and policy reasons why the Prosecutor should be entitled to lay alternative charges. We agree with the Prosecutor that there is a public interest in avoiding a multiplicity of charges.
33 We do not consider that there is any duplicity, unfairness or prejudice to the Defendant in allowing the matter to proceed on the basis of the respective offences against ss 8 and 10 being charged in the alternative.
Operation of the Criminal Procedure Act
34 We also agree with the Prosecutor that the Criminal Procedure Act 1986 permits the charging of alternative offences in an order pursuant to s 246 of that Act.
35 There was no dispute that the Industrial Court exercises summary jurisdiction in respect of prosecutions for occupational health and safety offences pursuant to s 168 of the Industrial Relations Act and, by virtue of that section, in accordance with Part 5 of Chapter 4 of the Criminal Procedure Act. However, the Defendant rejected the Prosecutor's contention that Part 2 of Chapter 2 of the Criminal Procedure Act 1986 also applies to such proceedings, and that the reference to "the offence charged in the order" in s 246 of the Criminal Procedure Act 1986 could be interpreted to mean "the offences charged in the order".
36 The application of Part 2 of Chapter 2 of the Criminal Procedure Act is set out in s 15 of that statute, which is in the following terms:
15 Application of Part
(1) This Part applies, to the extent that it is capable of being applied, to all offences, however arising (whether under an Act or at common law), whenever committed and in whatever court dealt with.
(2) In this Part:
indictment includes a court attendance notice or any other process or document by which criminal proceedings are commenced.
37 Whilst s 168 of the Industrial Relations Act refers only to the application of Part 5 of Chapter 4 of the Criminal Procedure Act, there is nothing in s 168 which expressly excludes, or limits in any way, the operation of s 15(1) of the Criminal Procedure Act 1986 and therefore the application of Part 2 of Chapter 2 of that statute. To limit the application of the Criminal Procedure Act in these proceedings to only Part 5 of Chapter 4 would be an overly narrow interpretation of s 168 of the Industrial Relations Act.
38 We agree with Mr Agius that:
(a) the definition of "indictment" in s 15(2) includes an application for an order pursuant to s 246 of the Criminal Procedure Act 1986, being "any other process or document by which criminal proceedings are commenced";
(b) s 23 of the Criminal Procedure Act 1986 explicitly recognises the right of the Crown to include alternative counts in an indictment (which, by virtue of s 15(2), includes an order pursuant to s 246);
(c) the reference to "an offence" and "the offence" in the singular in s 246 does not preclude charges being laid in the alternative: s 8(b) of the Interpretation Act 1987 states that "a reference to a word or expression in the singular form includes a reference to the word or expression in the plural form".
The Common Law
39 The view we have reached is confirmed when the situation at common law is considered, which plainly permits alternative charges being laid in criminal matters.
40 The Court of Criminal Appeal in R v Thomson; R v Dann (2002) 134 A Crim R 252 considered the question of whether the Crown may proffer an indictment containing counts that are contradictory. In finding that it may do so, Santow JA, with whom Hidden and Adams JJ agreed, referred to R v Healy (1995) 15 WAR 104 and R v Collins (1996) 1 QD R 631. Those cases each follow the decision of the House of Lords in R v Bellman [1989] 1 AC 836, in which Lord Griffiths stated (at 851) that "... there is no rule of law that prevents the inclusion in one indictment of mutually exclusive counts and that if, at the end of the prosecution case, the evidence establishes a prima facie case on both counts, the matter should be left to the jury to determine the question of guilt, and the prosecution should not be put to their election upon which count to proceed."
41 Santow JA concluded in R v Thomson; R v Dann:
Bellman is persuasive authority for the proposition, followed in Australia, that there is no rule of law that prevents the inclusion in one indictment of mutually exclusive counts, so long as:
