We agree with these observations. We would also add that other aspects of the purpose of the provisions include the protection of the public interest by, on the one hand, ensuring the proper efficiency and integrity of the teaching service and, on the other hand, providing that teachers, particularly those who are officers and thus permanent employees, have a reasonable degree of security of tenure (since they cannot be disciplined or dismissed without appropriate cause being shown).
47 It remains to determine whether her Honour erred in her approach taken to the construction of the 1970 Act. This entails an examination first of s 37(1) of the 1970 Act to see whether that section potentially affects incurred liabilities, and, therefore whether s 30(1)(c) of the Interpretation Act operates to preserve those incurred liabilities. It may then be necessary to ascertain whether the 1980 Act manifests a contrary intention such that that Act may be construed as altering those liabilities so that they are not preserved, and the operation of the Interpretation Act is displaced.
48 The potential liability under s 37(1) is the liability to punishment for a breach in contravention of any of its paragraphs. The appellant's alternative submission sought to draw a distinction between those paragraphs in s 37(1) which purportedly required first a finding of guilt in relation to the specified conduct (paragraph (b), (d) and (f)) and other paragraphs which did not (paragraphs (a), (c) and (e)). The first category, the appellant contended, referred to liabilities which were not complete because they were in effect contingent upon a future event, namely, a finding of guilt. The second category however referred to completed liabilities, in other words, liabilities that had been incurred, and were therefore amenable to the operation of s 30(1)(c) of the Interpretation Act.
49 An obvious difficulty with that construction of s 37(1), if accepted, is that some conduct within s 37(1) prior to 1980 could be dealt with after 1980 but other conduct within s 37(1) (that which involved reference to the word "guilty") could no longer found a basis for dealing with an alleged breach of discipline. Such a construction urged by the appellant in relation to paragraphs (b), (d) and (f), moreover, would entail a finding that a breach of discipline had been found to have been committed before any relevant enquiry had taken place. This plainly cannot be the intent of the provision.
50 Rather, we are of the view that the use of the word "guilty" in some of the paragraphs but not in the others is not a difference of any substance. Support for this may be found in the decision of the High Court in The Queen v White and others; Ex Parte Byrnes (1963) 109 CLR 665. In that case the applicant Mr Byrnes applied to make absolute an order nisi for a writ of certiorari. He had been charged by the Chief Officer of the Department of the Army with having wilfully disobeyed a lawful order. The charge was laid under s 55 of the Public Service Act 1922-1960 (Cth). Section 55(1) which was found in Division 6 of Part III of that Act provided that an officer who does or omits to do certain things as set out in paragraphs (a) to (h) of that subsection shall be guilty of an offence and shall be liable to punishment. The Court in dismissing the application said (at 670):
As has already appeared, we think that Div. 6 of Pt. III of the Act relating to offences is part of the law regulating the relationship between the Commonwealth and its servants; it is a law with very special application. Section 55, in creating so-called "offences" and providing for their "punishment", does no more than define what is misconduct on the part of a public servant warranting disciplinary action on behalf of the Commonwealth and the disciplinary penalties that may be imposed or recommended for such misconduct; it does not create offences punishable as crimes. The formalities prescribed in ss. 55, sub-ss.(3), (5) and (7), and 57, 58 and 60 (which counsel for the applicant described as "judicial trappings") are directed to safeguarding public servants from possible official injustice in the determinations whether there has been departure from the "code" established by s. 55 (1) and, if so, what punishment should be imposed. The establishment of these safeguards does not indicate that an officer whose conduct is being investigated is being tried for a criminal offence; indeed in the Act a clear distinction is drawn between criminal offences committed by public servants (s. 62) and breaches of the disciplinary code established by s. 55 (1).
51 If the reasoning in the above case is adapted to the circumstances here, the word "guilty" used in s 37(1) therefore has no significance over and above defining the relevant misconduct on the part of a teacher and others to which the section may apply which in turn may warrant disciplinary action on behalf of the teaching service. The Queen v White also shows the undesirability of the repeated use of the word "guilty" in s 37 and this may explain why the 1979 Public Service Act, and the 1980 Act which followed it, were modified to avoid the repetition.
52 We therefore differ from Schmidt J as to her Honour's conclusion that because of the alteration in the language used, the 1980 obligations were somewhat broader than those created by the 1970 Act. We consider that, notwithstanding the change in verbiage, the obligations relevantly imposed were the same under both Acts for all practical and legal purposes.
53 The analysis thus far of the legislative scheme and the relevant principles shows that, at the time the respondent came to consider commencing disciplinary proceedings against the particular teachers, the respondent was confronted with allegations of conduct some of which were alleged to have occurred prior to the 1980 Act coming into force but with apparently different statutory regimes deriving from the 1970 Act and 1980 Act which were, nevertheless in practical terms, identical, notwithstanding some verbal differences. Inevitably, the respondent would have been faced with a quandary as to how to frame the relevant disciplinary "charges", and particularly so as to which statute should be referred to in the "charges". As earlier noted, what occurred in 1980 involved the repeal of the 1970 Act and, most relevantly, the repeal of s 37(1) which related to the basis of disciplinary proceedings until its repeal in 1980.
54 Some assistance in this situation is available from decisions relating to courts being entitled to go behind the words used in situations of apparent repeal or amendment of statutes and the need for the court to determine for itself whether the effect of a provision is to repeal or to amend an existing statute. As Pearce and Geddes observe in the 2006 edition of their Statutory Interpretation in Australia (at p 247), the accepted authority in Australia for many years on the approach to be adopted to resolve this issue has been the judgment of Jordan CJ in Beaumont v Yeomans (1934) 34 SR (NSW) 562 at 569. In that case Jordan CJ said:
Whether an Act has been repealed or amended is a matter of substance and not one of form only. One Act may purport to amend another by repealing part of it. On the other hand, an amendment may be effected either by the addition to a section of a particular phrase, or by the repeal of the section and the substitution of the same words with the phrase added ... And where a provision of an Act is repealed and re-enacted in a form which enlarges its scope, this has been construed as amounting in substance to an amendment, because the new provision has been regarded as intended to be retrospective so far as it is merely repetition, and prospective so far as it is new: Ex parte Todd (1887) 19 Q.B.D. 186.
The approach of Jordan CJ in Beaumont v Yeomans was followed by a majority of the High Court in Bird v John Sharp & Sons Pty Ltd (1942) 66 CLR 233.
55 Further, the High Court recently observed, in Attorney-General (WA) v Marquet (2003) 217 CLR 545 at 564 - 565, that an analysis of relevant cases (including Beaumont v Yeomans) revealed that the words "amend" and "repeal" can be used in ways in which there appears to be some overlapping in their meanings, citing Kartinyeri v Commonwealth (1998) 195 CLR 337 at 375. The Court also held:
But concluding that the words have different meanings is not to say that the distinction between them always depends upon the form in which a particular piece of legislation is cast. The distinction must depend upon considerations of substance not form (the initial emphasis is in the original; the subsequent emphasis has been added).
56 The next question is whether s 37(1) is concerned with liabilities that have been incurred and which are therefore caught by s 30(1)(c) of the Interpretation Act unless a contrary intention may be found in the repealing legislation or other legislation which displaces its operation.
57 We do not agree with the finding of Schmidt J that s 30(1) of the Interpretation Act had the effect of continuing in force s 37 of the 1970 Act in respect of matters which occurred prior to 1980 and which could have been dealt with under s 37(1), but in respect of which proceedings had not actually been commenced prior to the repeal of s 37(1).
58 This conclusion involves an examination of the various potentially relevant aspects of s 30(1) of the Interpretation Act in light of the fact that what was in issue were disciplinary proceedings involving allegations of misconduct. We consider that the only parts of s 30(1) that could be relevant are paragraphs (c) and (e). However, as to paragraph (c), we do not consider the fact that there existed conduct which it was alleged could be later found to be "misconduct", or the fact that proceedings might be commenced in relation to such conduct, could be said to be "a right, privilege, obligation or liability acquired, accrued or incurred under the Act ..." Similarly, it could not be said that such matters were, absent the commencement of proceedings, an "investigation, legal proceeding or remedy" in terms of paragraph (e).
59 The difficulty in finding that s 37(1) is concerned with liabilities that have been incurred is that the provision, at its highest, deals with potential liability. On its proper construction, s 37(1) does not create any liability unless and until proceedings are commenced in respect of an alleged breach of discipline. As Windeyer J observed in Ogden Industries Pty Ltd v Lucas at 584, a provision such as s 30(1) "describes a liability having become complete by past events rather than a situation in which some future event must occur to make the effect of past events create a completed liability."
60 We should now return briefly to the presumption against retrospective operation, which was earlier referred to. This matter arises because of the question whether s 83 of the 1980 Act applies to conduct alleged to have occurred prior to its enactment. This question, in turn, raises the question whether s 83 is procedural or creates or affects substantive liabilities. Section 83 of the 1980 Act, as with s 37(1) of the 1970 Act which was discussed in the last paragraph of these reasons, does not create any liability; no liability crystallises until proceedings are commenced in respect of an alleged breach of discipline.
61 As adverted to earlier, procedural provisions do not fall within the application of the presumption against retrospectivity. This well established principle was dealt with in some detail in Maxwell v Murphy. In the passage already quoted (at 267 of the judgment) Dixon CJ observed that the law appointing or regulating the manner in which rights and liabilities are enforced or their enjoyment secured, is not within the application of the presumption. Later in the judgment (at 268) his Honour adopted the following passage from Wright v Hale (1860) 6 H&N 227 at 232:
The rule applicable to cases of this sort is that, when a new enactment deals with rights of action, unless it is so expressed in the Act, an existing right of action is not taken away. But where the enactment deals with the procedure only, unless the contrary intention is expressed, the enactment applies to all actions whether commenced before or after the passing of the Act.
62 The application and significance of procedural provisions to past events, was examined by the High Court in Rodway v The Queen (1990) 169 CLR 515 at 518 - 521. The Court there held:
The rule at common law is that a statute ought not be given a retrospective operation where to do so would affect an existing right or obligation unless the language of the statute expressly or by necessary implication requires such construction. It is said that statutes dealing with procedure are an exception to the rule and that they should be given a retrospective operation. It would, we think, be more accurate to say that there is no presumption against retrospectivity in the case of statutes which affect mere matters of procedure. Indeed, strictly speaking, where procedure alone is involved, a statute will invariably operate prospectively and there is no room for the application of such a presumption. It will operate prospectively because it will prescribe the manner in which something may or must be done in the future, even if what is to be done relates to, or is based upon, past events. A statute which prescribes the manner in which the trial of a past offence is to be conducted is one instance. But the difference between substantive law and procedure is often difficult to draw and statutes which are commonly classified as procedural -- statutes of limitation, for example -- may operate in such a way as to affect existing rights or obligations. When they operate in that way they are not merely procedural and they fall within the presumption against retrospective operation. But when they deal only with procedure they are apt to be regarded as an exception to the rule and, if their application is related to or based upon past events, they are said to be given a retrospective operation provided that they do not affect existing rights or obligations.
