[7] The laws of a State or Territory to which s 68(1) refers apply 'so far as they are applicable' Although there is not in s 68, as there is in s 79 of the Judiciary Act , an express qualification to the operation of the provision by the use of the words 'except as otherwise provided by the Constitution or the laws of the Commonwealth' in the context of a problem such as the present there is little, if any, functional difference between the two forms of qualification. The meaning of 'otherwise provided' was considered in Northern Territory v GPAO . Relevantly for present purposes, s 52 of the Sentencing Act would not be picked up and applied by s 68 if a Commonwealth law expressly or by implication made contrary provision, or if there were a Commonwealth legislative scheme relating to the sentencing of the appellant which was 'complete upon its face' and can 'be seen to have left no room' for the operation of s 52. Since the appellant relies upon both kinds of other provision, it is necessary to examine in some detail the Commonwealth laws that are said to have that effect." ( Putland , supra, per Gleeson CJ at 178-179)
30 Likewise the joint judgment of Gummow and Heydon JJ in Putland accepted the understanding of the parties that s 68(1) is to be read as if "as a matter of express statement rather than implication, there was a qualification for provision otherwise made from time to time by the laws of the Commonwealth": (Putland at [41], per Gummow and Heydon JJ with whom Callinan J agreed).
31 By operation of s 68(1) of the Judiciary Act, the relevant state laws become laws of the Commonwealth. There is no room for the operation of s 109 of the Constitution. Therefore any repugnancy or inconsistency must be approached from the aspect that it is s 68 and the other Commonwealth law that is inconsistent and not from the standpoint that the other Commonwealth law prevails because there is an inconsistency with a State law: see University of Wollongong v Metwally [1984] HCA 74; (1984) 158 CLR 447 at 463 per Mason J.
Are section 68 of the Judiciary Act and section 20BQ of the Crimes Act (Cth) inconsistent?
32 Insofar as s 68(1) of the Judiciary Act purports to make s 32 of the State Act a law of the Commonwealth, it does so by governing a class of persons, to whom it then applies the regime in s 32 of the State Act. That class is any person who is or was suffering a mental illness but "is not a mentally ill person within the meaning of Chapter 3 of the Mental Health Act 1990".
33 On the other hand, s 20BQ of the Crimes Act (Cth) applies only to a person who "is suffering from a mental illness within the meaning of the civil law of the State". A person who is mentally ill within the meaning of Chapter 3 of the Mental Health Act is, at least, part of the class of persons defined by the term "mentally ill" "within the meaning of the civil law of the State".
34 What is "the civil law of the State"? If, as decided by the learned magistrate, the term were confined to persons governed by the Mental Health Act, then, expressly, s 20BQ of the Crimes Act (Cth) applies only to such persons and s 68(1) of the Judiciary Act, in applying s 32 of the State Act, expressly, does not apply to such persons.
35 Therefore, if the learned magistrate be correct in her construction of the meaning of "civil law" in this context, there can never by an inconsistency between any operation of s 20BQ of the Crimes Act (Cth) and s 32 of the Mental Health (Criminal Procedure) Act. The former applies to defined mentally ill persons; the latter applies to those who are not. The world, in logic, consists of "X" and "not X", which are opposites. In this case the class of "mentally ill persons" consists of those governed by the Mental Health Act and those that are not. The sub-classes are mutually exclusive and the sections, in questions here, deal with each sub-class.
36 But is the learned magistrate correct in limiting "mentally ill" in that way? And does it make a difference? The term "civil law" may have a number of meanings depending on the context. It may describe the system of law, other than the common law system, deriving from Roman Law. Given that no Australian State operates under the civil law system, it cannot have that meaning. The term "civil law" may be, and in my view on this occasion is, used to describe the law of private or civil rights, as opposed to the criminal law. In this use, depending on context, it may or may not include public rights and duties in administrative law. It is unnecessary to deal with that question.
37 Mr Saadat-Talab submits that, if, as I have determined, the proper construction of s 20BQ of the Crimes Act (Cth) is that the term "civil law" includes the common law as well as statutory provisions, then Mr Saadat-Talab fits the meaning of "mentally ill" within the common law. Counsel cites, as an example, a person suffering a mental condition as a result of a traumatic event caused by the negligence of another.
38 For the reasons that follow, it is unnecessary to determine the extent of the definition. However, I make the following comments. It is, in my view, very different to refer, in legislation of this kind (s 20BQ of the Crimes Act (Cth)) to "mental illness" than to refer to an injury including a disease. A traumatic injury may cause a "mental illness". Certainly, for example, some negligently caused birth defects may be so described. But it is an altogether different proposition to that which is advanced on behalf of Mr Saadat-Talab. "Mental illness", even under the common law, seems a narrower concept than mental or psychiatric injury. The latter may or may not seriously impair mental functioning and that "mental impairment" criterion seems at the core of "mental illness". I do not finally determine this issue.
39 Lastly, and most importantly in determining the issues in these proceedings, I deal with whether, as the Director of Public Prosecutions (Cth) submits, s 20BQ of the Crimes Act (Cth) is a "code". This submission is essentially that the Commonwealth, having prescribed a method of diverting punishment in some cases, should be taken to have excluded diversionary orders in others: see Saraswati v R [1991] HCA 21; (1991) 172 CLR 1 at 23-24; Anthony Hordern & Sons v Amalgamated Clothing and Allied Trades Union of Australia [1932] HCA 9; (1932) 47 CLR 1 at 7; Leon Fink Holdings Pty Ltd v Australian Film Commission [1979] HCA 26; (1979) 141 CLR 672 at 678.
40 The difficulty with such a submission is that the term diversionary order is a common abbreviation of the effect of the order. But orders under these sections (ss 20BQ and 32) are not the only means whereby a person suffering a mental disorder (whether at the time of sentencing or commission of the offence) may avoid conviction for an offence committed: s 19B of the Crimes Act (Cth) allows extenuating circumstances that affected the commission of the offence to be a factor in not recording a conviction. That a person was suffering a mental disorder at the time of the commission of an offence must be a factor considered under s 19B or otherwise in determining an appropriate sentence: see Veen v R (No 2) [1988] HCA 14; (1988) 164 CLR 465 at 476-477 (per Mason CJ, Brennan, Dawson and Toohey JJ). Therefore, s 20BQ of the Crimes Act (Cth) does not purport to be the exclusive means of either dealing with mental disorder (a broader term than mental illness) or with utilising mental disorder in determining, notwithstanding "guilt", not to proceed to convict.
41 Lastly, is the above construction one which accords with the disclosed purpose of the legislature: Project Blue Sky Inc v Australian Broadcasting Authority [1998] HCA 28; (1998) 194 CLR 355 at [78]? Does its provisions, as construed, give effect to harmonious goals: Project Blue Sky, supra, at [70]?
42 In introducing s 20BQ of the Crimes Act (Cth) the Minister said:
"The primary purpose of the Crime Legislation Amendment Bill (No. 2) 1989 is to review the Commonwealth sentencing legislation and the laws governing Federal offenders found unfit to be tried or not guilty on the grounds of mental illness.
