[61] The corporate respondent would, therefore, have no prior convictions under the Act. The personal respondent has no prior convictions under the Act.
18 We consider that the conclusion as to the proper interpretation of s51A of the 1983 Act is correct. The issue then in the present circumstances is whether the changes in the wording between s51A of the 1983 Act and ss4 and 12 of the Act warrant a departure from that authority. For the reasons we shall give, we do not believe the result should differ in the present proceedings.
19 We observe also that we agree with the approach to statutory interpretation taken in Morrison v Powercoal (No 3). Accordingly, we adopt the approach to the need to interpret ss4 and 12 in the context of the Act and in the context of the relevant general law. Further, we accept the importance of construing the provisions strictly given that the consequence of a person falling within the definition of "previous offender" is the possibility of the imposition of a custodial sentence.
20 The definition of "previous offender" in s4 directs attention to whether a person has previously been convicted of an offence against the Act or against the 1983 Act. In this respect, we see no relevant distinction between the definition of "previous offender" and the terms of s51A(1). We note in this regard that Staunton J was concerned with the reference to "at any time" and drew from those words a clear meaning that the relevant element was a conviction at any time prior to sentencing. As to this aspect, we see no relevant distinction in their respective intentions between the words "at any time" and "has previously been convicted" that appeared in s51A(1). Even if the expression "at any time" could be considered wider, there is a clear overlap between the two phrases, in that they both refer to events occurring before sentencing. For present purposes, there is no relevant distinction.
21 The real issue in the present case is the identification of the offence in respect of which there is a previous conviction. On a literal reading, the requirement is "any other offence of any kind". In s51A(1), the analogous requirement was "an offence against this Act (whether the same offence or another)". We see no relevant distinction between "an offence" in s51A and "any other offence" in the definition of "previous offender".
22 In Morrison v Powercoal (No 3), the reference to "has previously been convicted of an offence" was then interpreted in the context of the section and against the background of the general law. The reference in s51A(3) to "previous offence" was seen as intended to reflect a general approach that the section was intended to apply to previous offences, rather than previous convictions. Further, the context of the general law was a concern to impose a greater penalty for a conviction arising from the occurrence of a second offence, that is, "where the offender has in a genuine sense offended on a subsequent occasion". We consider the analysis undertaken in Morrison v Powercoal (No 3) as directly applicable to the present circumstances.
23 While there is no similar reference to "previous offence" in ss4 or 12 as there was in s51A(3), the description of the defined term is "previous offender". It is then only used in s12. Section 12 sets out the penalties for an offence against the Division and provides two tiers of penalties for each of a company and an individual. The tiers of penalties are such that a higher penalty may be imposed where the person is a "previous offender". In other words, the context in which the definition is used is consistent with the general law that a person who has been convicted of a prior offence is potentially subject to a higher penalty when being sentenced for the offence committed after conviction for the prior offence. Given the context in which the definition of "previous offender" is used in s12, read within the context of the general law and when the legislature has used the phrase "previous offender" to describe the person, we consider that it is plain that the reference is to a conviction for a previous offence.
24 In referring to the context of the provisions we do so in the widest sense to include the existing state of the law. This is consistent with the approach taken in Morrison v Powercoal (No 3) and other authorities: see CIC Insurance Ltd v Bankstown Football Club Ltd (1997) 187 CLR 384 at 408.
25 In this regard, we agree with the submissions of counsel that this conclusion gives effect to the apparent purpose of the provision. We consider the observations as to purpose made by this Court in Morrison v Powercoal (No 3) to be directly applicable. The observations made by the Attorney-General and Minister for Industrial Relations in the second reading speech for the Act are also relevant:
A major theme covered by a number of recommendations is the need to overhaul the Occupational Health and Safety Act 1983. This has been achieved with the development of an entirely modernised bill. It is now in plain English and has been reorganised in a coherent manner that will facilitate comprehension and access. However, there has been no substantive change to the meaning except for those matters to which I will refer today.
26 We concur with the submissions of the counsel for the defendants made to Staunton J that in the remainder of the speech the Attorney-General made no mention of any intention to change the procedure by which offenders had been sentenced under s51A of the 1983 Act or to change the meaning or effect of a prior offender.
27 Further, it is consistent with the overall purpose of the Act, which is not only to allow imposition of punishment for breaches of the Act but, importantly, its purpose is to provide practical deterrents by promoting, encouraging and securing workplace safety.
28 We also agree with the defendants' submissions that no intention can be imputed from the text of the legislation that the legislature intended to interfere with the general law position, namely the long-standing sentencing principles to impose a greater penalty for subsequent offences and for that matter the law as stated in Morrison v Powercoal (No 3). Were that to have been the intention, it would need to have been done by unmistakable and unambiguous language: see Coco v R (1994) 179 CLR 427.
29 We should note that counsel for the prosecutor submitted that we should interpret s12 in the way we have done by an application of the approach taken by McHugh JA in Bermingham. We turn to briefly consider this submission.
30 In Bermingham, McHugh JA made the following observations:
The Interpretation Act 1987, s 33, directs the Court to give legislation the construction which promotes its purpose or object. In Kingston v Keprose Pty Ltd (1987) 11 NSWLR 404, I set out in some detail (at 421-424) the principles applicable in giving legislation a purposive construction. The passage is too long to set out at length. But in the course of that judgment I pointed out that the grammatical meaning of a provision is not to be taken to represent Parliament's intention as to its meaning when the context or the purpose of the provision raises a real doubt about the applicability of the grammatical meaning. If purpose or context do raise a real doubt as to whether Parliament intended the grammatical meaning to apply, a court is entitled to depart from that meaning. Moreover, if the grammatical meaning gives rise to injustice or anomaly, it may strengthen the conclusion that the Parliament did not intend the grammatical or literal meaning to apply.
Once the court concludes that the grammatical meaning does not accord with the purpose of the legislation, " … it is often legitimate, because it is necessary, to put a strained interpretation upon some words which have been inadvertently used": Sutherland Publishing Co Ltd v Caxton Publishing Co Ltd [1938] Ch 174 at 201. But as the cases to which I referred (at 422-423) in Kingston v Keprose Pty Ltd show, it is not only when Parliament has used words inadvertently that a court is entitled to give legislation a strained construction. To give effect to the purpose of the legislation, a court may read words into a legislative provision if by inadvertence Parliament has failed to deal with an eventuality required to be dealt with if the purpose of the Act is to be achieved.
