(a) definition of corrupt conduct
50Section 8 relevantly provides:
8 General nature of corrupt conduct
(1) Corrupt conduct is:
(a) any conduct of any person (whether or not a public official) that adversely affects, or that could adversely affect, either directly or indirectly, the honest or impartial exercise of official functions by any public official, any group or body of public officials or any public authority, or
(b) any conduct of a public official that constitutes or involves the dishonest or partial exercise of any of his or her official functions, or
(c) any conduct of a public official or former public official that constitutes or involves a breach of public trust, or
(d) any conduct of a public official or former public official that involves the misuse of information or material that he or she has acquired in the course of his or her official functions, whether or not for his or her benefit or for the benefit of any other person.
(2) Corrupt conduct is also any conduct of any person (whether or not a public official) that adversely affects, or that could adversely affect, either directly or indirectly, the exercise of official functions by any public official, any group or body of public officials or any public authority and which could involve any of the following matters:
(a) official misconduct (including breach of trust, fraud in office, nonfeasance, misfeasance, malfeasance, oppression, extortion or imposition),
(b) bribery,
...
(g) perverting the course of justice,
...
(x) matters of the same or a similar nature to any listed above,
(y) any conspiracy or attempt in relation to any of the above.
...
(6) The specific mention of a kind of conduct in a provision of this section shall not be regarded as limiting the scope of any other provision of this section.
51While s 8(6) expressly requires that one provision not be read down by some implication deriving from the scope of another, it is nevertheless necessary to read the section as a whole, and in the context of the objects of the Act (s 2A), the functions of the Commission (Pt 4), including the reporting functions set out in Pt 8.
52It is not necessary to set out the provisions of Pts 4 and 8, but reference will be required to the language of s 2A, which reads as follows:
2A Principal objects of Act
The principal objects of this Act are:
(a) to promote the integrity and accountability of public administration by constituting an Independent Commission Against Corruption as an independent and accountable body:
(i) to investigate, expose and prevent corruption involving or affecting public authorities and public officials, and
(ii) to educate public authorities, public officials and members of the public about corruption and its detrimental effects on public administration and on the community, and
(b) to confer on the Commission special powers to inquire into allegations of corruption.
53The structure of s 8(1) and (2) is of some importance. It is in form and effect a definition of "corrupt conduct", as is recognised by s 3(1), corrupt conduct. The use of the adverb "also" in subs (2) indicates that subs 8(1) is the primary part of the definition. Of the four paragraphs in subs (1), all apply to the conduct of a public official, but par (a) applies to the conduct of any person, whether or not a public official. The evil or mischief at the heart of par (a) (complemented by (b)) is the dishonest or partial exercise of an official function. The provision covers both dishonesty and partiality on the part of a public official and conduct of a second person which may seek to induce or encourage dishonesty or partiality on the part of a public official. Thus, to take an obvious example, the offering of a bribe to an electoral officer by a private person could fall within par (a) because it could adversely affect the honest and impartial exercise of the electoral officer's functions.
54The word "also" has a second significance: it indicates that subs (2) is intended to extend the scope of the definition in subs (1). The first limb of subs (2) mirrors subs (1)(a), incorporating the concept of an adverse effect, but omitting the reference to "honest or impartial" exercise of official functions. The omission of that qualifying phrase must be taken to allow for adverse effects which do not fall within the concepts of dishonesty and partiality. By way of balance, the second limb is a restriction on the operation of subs (2), namely that the conduct could involve any of the long list of crimes and other official misconduct, which concludes with a dragnet of matters of the same or similar nature to those listed: par (x).
55How the list operates is less clear. Subsection (2), like subs (1)(a), must be given a distributive operation. That is, it applies to the conduct of both public officials and others. To the extent that it applies to the conduct of others, that conduct must nevertheless be capable of adversely affecting the exercise of an official function by a public official. The comparison between subs (1)(a) and subs (2) with respect to the conduct of those who are not public officials may be paraphrased as follows (using the term "private person" to refer to someone other than a public official): the former provision catches any conduct of a private person which could adversely affect the honest or impartial exercise of official functions; the latter provision catches conduct which both falls within the list and could adversely affect the exercise of official functions in an unspecified manner.
56There is undoubtedly much overlap between the scope of s 8(1) and s 8(2): the first step is to identify in what manner the latter extends the former with respect to conduct of a private person. That involves asking what sort of adverse effect on the exercise of official functions is envisaged by subs (2). For example, a dishonest statement as to the sale price of a property, for the purpose of reducing an assessment of duty, might involve an offence under Pt 8 of the Taxation Administration Act 1996 (NSW) and thus be a form of "tax evasion" for the purposes of subs (2)(m). The result might be that an official assessed an inadequate amount of duty, but in doing so the official would be acting honestly, impartially and in accordance with his or her statutory obligations.
57By way of an example closer to the present case, the fact that a driver tells a lie about his health in order to avoid being breathalysed in circumstances where the driver thinks his blood alcohol level is above the prescribed limit, would not involve any dishonest or partial conduct on the part of the police officer, who would be exercising a discretionary power appropriately according to the facts which the officer reasonably believed at the time. The question is, in each case, whether the result of the conduct of the private person, namely that a tax payer avoids paying his or her full legal liability or a potential offender escapes prosecution, attracts the description of conduct which "could adversely affect ... the exercise of official functions by any public official". (In each case the conduct would appear to satisfy the second limb.)
58The applicants submitted that the two limbs of s 8(2) could be satisfied only by separate acts or omissions. Were that not the case, the submission continued, any criminal conduct which fell within the list could become the subject of investigation by the Commission. This submission cannot be accepted in its terms. There is nothing in the statutory language which requires two separate acts, as distinct from an act which has two prescribed characteristics. On the other hand, many circumstances will involve conduct having at least two elements. Furthermore, there is substance in the underlying premise, namely that subs (2) must not be read in a way which gives no work to the first prescribed characteristic, so that any conduct falling within the list of unlawful activities (primarily criminal) would suffice to engage the functions of the Commission.
59Whether subs (2) requires one or more than one activity in a particular case will depend upon two elements. First, in a practical sense, it will make a difference whether the conduct which is the subject of the first limb of subs (2) is the conduct of a private person or a public official. Secondly, it will depend on the nature of the unlawful conduct.
60In one sense, the applicants' submission may have depended upon an assumption as to the scope of the term "conduct", which is not a defined term and is to be understood in the natural and ordinary meaning of the word. That meaning depends upon the context in which it is used and the circumstances to which it may apply. To take a simple example of a bribe offered to a police officer to overlook criminal conduct, there could be a single course of conduct or two separate activities each constituting conduct. Thus, the offering of a bribe by the private person would constitute corrupt conduct satisfying both characteristics identified in subs (2). Acceptance of the bribe could fall within the subs (1) or subs (2), but in the latter case because it is conduct which could adversely affect the exercise by the officer of his or her official functions. It might be thought to be an awkward reading of the provision (and this may be part of the applicants' submission) to fit within it the conduct of the corrupt police officer as being both the "conduct of any person" and having the effect of compromising "the exercise of official functions by any public official", being the same person. Such conduct would more naturally fall within subs (1)(b). How that issue should be addressed is not critical for present purposes: rather, the applicants' case must turn upon the meaning of "adversely affects" and its contingent form "could adversely affect".
61If subs (2) were satisfied whenever a private person understates his or her income in order to avoid paying the full amount of tax, the first limb of subs (2) will be deprived of effect, so long as the conduct constituted (in this example) "tax evasion" under the second limb. To the extent that such conduct might fall within a possible understanding of conduct which adversely affects the exercise of official functions, because the result is to reduce public revenue, that reading should not be accepted. Some more limited understanding must be given to the term "adversely affect". The appropriate limitation must be derived from the statutory context.
62On one view, the ordinary meaning of corrupt conduct would require a partial or dishonest exercise of an official function by a public official. However, to read the first limb of subs (2) as so limited would render it superfluous, because it would then cover precisely the same conduct as subs (1)(a). The omission of that language from subs (2) must have been deliberate, not to avoid overlap, but to allow a broader field of conduct to be identified.
63There are two respects in which the first limb of subs (2) expands the coverage of subs (1). First, it expands the scope of pars (b), (c) and (d) of subs (1), which are restricted to the conduct of public officials and, in the case of (c) and (d), former public officials. Subsection (2) is not so limited: it applies generally to conduct of private persons and public officials.
64Secondly, the apparent purpose of subs (1)(c) and (d) is to expand the concept of dishonest or partial exercise of an official function to conduct involving a "breach of public trust" or "misuse of information or material that he or she has acquired in the course of his or her official functions". Thus, subs (2) would, on one construction of the expression "adversely affect", cover the conduct of a private person designed to achieve a breach of public trust by a public official, where the conduct of the private person would not fall within subs (1)(c). It could also cover the conduct of a public official who seeks to have others breach public trust or misuse information obtained in the course of their official functions.
65No doubt there might be a serious question as to whether such conduct could also fall within the concepts of dishonesty or partiality which limit the operation of subs (1)(a) and (b), but the drafter having adopted different language one should assume it was not superfluous or otiose, but expansive of the other paragraphs.
66On this approach, the first limb of subs (2) will, first, cover the exercise of official functions in a way which may not properly be characterised as dishonest or partial; secondly, cover the activities of both private persons and public officials which would not necessarily fall within subs (1), but thirdly, impose a constraint on the term "adversely affect" which is consistent with the ordinary understanding of corruption affecting public authorities and public officials. This approach excludes from the scope of the Commission's functions conduct which may be unlawful but does not involve corruption or corrupt conduct because it does not compromise public administration. By contrast, a tax payer offering a benefit to a public official in order to curry favour, with the intention of avoiding an inquiry into one's actual income, would constitute a form of corruption. Thus the adverse effect on public administration arises in the latter case, but not in the former.
67Such an approach derives contextual support from the language of s 2A, set out at [52] above, identifying the principal objects of the ICAC Act. The explicit mischief to which the Act is directed is "corruption involving or affecting public authorities and public officials" and the detrimental effect of such corruption on "public administration and on the community". It is evident from this language, and the two-limbed structure of s 8(2), that the Act is not concerned with, nor does it require investigation of, all unlawful conduct which could adversely affect public administration even quite directly, such as tax evasion and revenue evasion: see s 8(2)(m) and (n).
68Senior counsel for the Commission submitted that such an approach would run foul of the principle that one not use the ordinary meaning of the defined term in order to give meaning to the definition. Further, to the extent that the scope of the definition is being approached by reference to the broad purposes of the Act, as stated in s 2A, that section merely picked up "other parts of speech and grammatical forms of the [defined] word or expression", which should be given "corresponding meanings", pursuant to s 7 of the Interpretation Act 1987 (NSW).
69While it may be accepted that the purpose of s 7 is to give an expanded operation to a statutory definition, it may be doubted whether "corruption" bears the necessary relationship to the defined term "corrupt conduct" to fit within the linguistic operation identified in s 7. More importantly, there is no rigid principle which requires that a statutory definition, which itself requires interpretation, should be abstracted from its statutory context, given a meaning and then reinserted in an operative provision. The Act, including any defined terms, should be read as a whole: context is often important and sometimes determinative.
70This Court considered the use of the defined term to understand a definition in Tovir Investments Pty Ltd v Waverley Council [2014] NSWCA 379. There can be no universal rule against such an approach; in the present circumstances, the preferable approach is to have regard to both the apparent purpose expressed in the principal objects of the Act, which do not themselves use the defined term "corrupt conduct", and the ordinary meaning of corruption in relation to the administration of the government.
71On that basis, the reference in s 8(2) to conduct which could "adversely affect" the exercise of an official function should be understood to refer to conduct which has the capacity to compromise the integrity of public administration, rather than simply, for example, adversely affect government revenue.
72There are two further factors to be noted. First, it may have been implicit in the Commission's approach that some different analysis is required with respect to perverting the course of justice. In other words, the nature of the offence may be such that any conduct having that effect will be conduct which adversely affects, or could adversely affect, the exercise of official functions by a public official.
73If that approach were to be accepted, it would mean that, at least with respect to such conduct, the careful construction of s 8(2), involving two separate characteristics, would be otiose. The justification for reading the concept of adverse affectation differentially in this way was not articulated. It is not consistent with conventional approaches to statutory interpretation.
74How this reasoning might operate may appear more clearly after reference is made below to the concept of perverting the course of justice. However, the statutory construction may be identified briefly as follows. Interference with or deflection of a police investigation does not of itself constitute perverting the course of justice. However, where such conduct is intended, and tends, to have the effect of deflecting officials from undertaking a criminal prosecution, it may interfere with (and thus pervert) the course of criminal justice as administered by a court.
75However, the police officer to whom the private person lies or seeks to mislead, will not be compromised in any of the senses referred to above. That officer will not be deflected from an honest and impartial exercise of his or her functions, nor inveigled into a breach of public trust, nor into misuse of information acquired in an official capacity. Thus the first characteristic identified above would not be satisfied. Nor is there any clear reason for thinking that it should be satisfied in such circumstances. The short point may be stated in somewhat incomplete terms as follows: where the conduct of an individual is unlawful within one of the paragraphs in subs (2), but that conduct does not (and does not have the capacity) to lead a public official into dishonest, partial or otherwise corrupt conduct, subs (2) will not catch the conduct.
76Secondly, it has not been necessary for the purposes of this analysis to determine whether the concept of a "breach of public trust" involves something other than the dishonest or partial exercise of an official function, so as to give pars (b) and (c) different applications. It should be assumed that the drafter intended that the different language covered different conduct. In Greiner v Independent Commission Against Corruption (1992) 28 NSWLR 125 Gleeson CJ said at 135:
"Reverting to s 8(1), the two concepts involved in that provision which were regarded by the Commissioner as relevant are those of partiality, and breach of public trust. As it happens, the only form of breach of public trust relied upon was partiality and therefore, for practical purposes, it became unnecessary to explore the meaning of the expression 'breach of public trust'."
77Mahoney JA, who took a somewhat different approach to that of Gleeson CJ and Priestley JA, did discuss to a limited extent the concept of "breach of public trust". After referring to some historical precedents, Mahoney JA stated at 165F:
"It is not necessary to attempt a precise definition of the term where used in s 8(1). It includes the misuse of an office or of the powers of an office in circumstances such as the present. The Commissioner concluded that Mr Greiner and Mr Moore used their position, their power and the influence it gave them to procure the preferment of Dr Metherell for the purpose of achieving for them a political advantage and, perhaps, in the case of Mr Moore, to assist a friend. This is a use of the trust confided in them for a purpose for which it was not given."
78Broadly speaking, this reflects the concept of improper purpose in administrative law, which extends beyond the concepts of honesty and impartiality.
