The appeal and its disposition
42 It is convenient to discuss the legislative scheme for creating and making AWA's before turning to the specific issues raised in the appeal. The legislative scheme discussed earlier is unclear in at least two respects. The first is whether an AWA needs to deal in a comprehensive way with terms and conditions and employment. The answer is apparently not. Section 170VF establishes as an essential characteristic of an AWA that it be a written agreement that deals with matters pertaining to the relationship between an employer and employee. The reference to "matters" in that section is of some importance to this appeal and will be discussed below. An agreement which dealt with one or a limited number of conditions of employment, would satisfy that description in s 170VF. Moreover s 170VG, which concerns the content of an AWA, requires a certain minimum content. However that section does not suggest that beyond the identified minimum, the AWA must deal with other matters though plainly the section contemplates it can. In addition, by operation of s 170VR an AWA prevails over conditions of employment specified in a State law to the extent of any inconsistency. However the section appears to be drafted on the assumption that an AWA might not deal with certain conditions of employment which themselves were dealt with by a State law.
43 In any event, it might be expected that an AWA will not deal with all aspects of the employment relationship and leave some room for the operation of terms implied by the common law as could have been the case in relation to comprehensive industry awards made under the Act in an earlier form: see the observations of Wilson J in Ansett Transport Industries (Operations) Pty Ltd v Wardley (1997) 142 CLR 237 at 287 but compare the observations of Mason, Brennan and Deane JJ in Metal Trades Industry Association v Amalgamated Metal Workers' and Shipwrights' Union (1983) 152 CLR 632 at 649. That said, the parties may endeavour to create an entire employment agreement and exclude terms which might otherwise have been implied by law: see the observations of McHugh and Gummow JJ in Byrne v Australian Airlines Ltd (1995) 185 CLR 410 at 450. On one view that is what the respondent and the appellant sought to achieve in the present matter with clause 1.4.2 set out above at [13].
44 The second uncertainty concerning the operation of Part VID is the relationship between an AWA and the contract of employment. A related question is the effect of the statutory scheme in Part VID on the capacity of the parties to an AWA to reach agreement, with immediate binding and enforceable legal effect, on matters relating to the employment relationship. Part VID does not appear to address, at least explicitly, the effect of an AWA on contractual arrangements between the parties to an AWA. Obviously if the contractual terms are embodied in an AWA, this issue does not arise. If, however, the agreement which becomes the AWA addresses only some aspects of the employment relationship, questions may arise about its effect on other aspects of the employment relationship dealt with, either expressly or impliedly (as a matter of fact or law), by the contract of employment and, in particular, contractual terms agreed to after the AWA came into force.
45 It is to be recalled that Division 6 of Part VID deals with the effect of an AWA. It gives paramountcy to an AWA in specified ways. In relation to an award made under the Act, the AWA operates to the exclusion of the award and similarly operates the exclusion of any State award or State agreement: see s 170VQ. In certain circumstances the AWA is subordinated to a certified agreement and such an agreement prevails over the AWA to the extent of any inconsistency. Subject to qualifications, an AWA prevails over conditions of employment specified in a State law to the extent of any inconsistency: s 170VR. The expression "State law" is defined and the definition rather suggests it is a reference to legislation given the reference, in the definition, to instruments made under a law of a State. In any event, s 170VR cannot validly have a wider operation than s 109 of the Constitution and the better view is that s 109 operates on State legislation: see Amalgamated Society of Engineers v Adelaide Steamship Co Ltd (1920) 28 CLR 129 at 155 and Hanks: Australian Constitutional Law, seventh edition at 8.6.1. That is not to say, however, that a Commonwealth law might not, as a matter of construction, evince an intention to override the common law: see Ansett Transport Industries (Operations) Pty Ltd v Australian Federation of Air Pilots (1989) 95 ALR 211 at 244. Accordingly, if Division 6 is silent on the effect of an AWA on the common law (and, in particular, contractual provisions made and enforceable under the common law) it can be assumed an AWA does not derogate from contractual terms concerning rights and obligations not dealt with by the AWA whether agreed to before the AWA was entered into or after. This last observation is subject to a qualification to which we now turn.
46 As just noted, and AWA is given paramountcy over awards under the Act and as well as qualified paramountcy over State laws, awards and agreements. An AWA is, for this reason, a potent instrument. However as is apparent from the sections set out at [30] to [38] above, the legislature has been assiduous to ensure that at least as a matter of legislative framework, AWAs are the product of free bargaining that does not disadvantage the employee. The legislature has sought to ensure free bargaining, to the extent that legislation can achieve that result, by prohibiting duress and requiring the Employment Advocate to be satisfied that the employee genuinely consented to making the AWA. Moreover the legislature has recognised the potentially vulnerable position of the employee by requiring the Employment Advocate to be satisfied that the employee has genuinely consented.
47 Having regard to this protective legislative framework, it is unlikely that the legislature intended that the parties to an AWA could reach agreement under the umbrella of that protection about matters pertaining to the employment relationship, obtain approval from the Employment Advocate thereby removing protection which might be afforded by an award (made under the Act or a State award) or afforded by State law, and thereafter bargain without similar protection to reach a collateral agreement (enforceable under the common law) imposing additional burdens on an employee in relation to matters dealt with by the AWA. Indeed it is for this reason (and probably one other) that the Act contains procedures with that protection for parties to an AWA to reach, and obtain approval for, a variation agreement. The other reason would be to allow the parties to an AWA to add to the AWA provisions concerning a matter not then dealt with by the AWA.
48 Nothing in the actual language used by the legislature would suggest a different conclusion. As noted above, a variation agreement is defined in s 170VA as meaning "an agreement to vary an AWA". It is to be recalled that the essential characteristic of an AWA identified by s 170VF is that it is an agreement "that deals with matters pertaining to the relationship between an employer and employee" (emphasis added). Section 170VL provides that an employer and an employee may make a written agreement varying an AWA. While the heading to the section speaks of varying the "terms" of the AWA, the heading does not form part of the Act: see s 13 of the Acts Interpretation Act 1901 (Cth). The language used to describe a variation agreement having regard to the processes which must be undertaken for its approval, are consistent with such an agreement being directed not only to varying the text of an agreement but varying the substance of the agreement as well. Indeed it might be thought that the statutory scheme of approval was directed primarily to the latter type of variation. In our opinion, if an AWA deals with a particular matter pertaining to the relationship between an employer and employee, then the parties to the AWA can only alter their rights and obligations in relation to that matter in a way which might disadvantage the employee, by entering into and obtaining approval for, a variation agreement. By clear implication, the Act prohibits the alteration of such rights or obligations which might disadvantage the employee by means other than those provided in the Act and renders ineffectual any agreement which purports to do so.
49 Broadly similar considerations inform discussion about whether contracts are unenforceable because they are tainted by illegality. A leading Australian authority in this area is Yango Pastoral Company Pty Ltd v First Chicago Australia Ltd (1978) 138 CLR 411. In issue was whether a section in the Banking Act 1959 (Cth) which prohibited a company carrying on a banking business without an authority, rendered unenforceable a mortgage and guaranteed given to a body corporate which had lent money and thereby engaged in unauthorised banking business. The applicable principles were discussed by Gibbs ACJ and Mason and Jacobs JJ. Gibbs ACJ said (at 423):
There are four main ways in which the enforceability of a contract may be affected by a statutory provision which renders particular conduct unlawful: (1) the contract may be to do something which the statute forbids; (2) the contract may be one which the statute expressly or impliedly prohibits; (3) the contract, although lawful on its face, may be made in order to effect a purpose which the statute renders unlawful; or (4) the contract, although lawful according to its own terms, may be performed in a manner which the statute prohibits.
In the present case we are not concerned with the first of these possible situations. Clearly s 8 does not render it unlawful to borrow or lend money or to give and take a mortgage, supported by guarantees, to secure its repayment. The contract sued upon was therefore not to do anything which s 8 forbids. The principal question in the case is whether s 8, on its proper construction, prohibited the making or performance of the contract. As will be seen, if that question is answered in the negative, it will not be possible to say that the contract cannot be enforced on the ground that it was made in order to effect an unlawful purpose or was performed in an unlawful manner.
It is often said that a contract expressly or impliedly prohibited by statute is void and unenforceable. That statement is true as a general rule, but for complete accuracy it needs qualification, because it is possible for a statute in terms to prohibit a contract and yet to provide, expressly or impliedly, that the contract will be valid and enforceable. However, cases are likely to be rare in which a statute prohibits a contract but nevertheless reveals an intention that it shall be valid and enforceable, and in most cases it is sufficient to say, as has been said in many cases of authority, that the test is whether the contract is prohibited by the statute. Where a statute imposes a penalty upon the making or performance of a contract, it is a question of construction whether the statute intends to prohibit the contract in this sense, ie to render it void and unenforceable, or whether it intends only that the penalty for which it provides shall be inflicted if the contract is made or performed.
The question whether a statute, on its proper construction, intends to vitiate a contract made in breach of its provisions, is one which must be determined in accordance with the ordinary principles that govern the construction of statutes. "The determining factor is the true effect and meaning of the statute": St John Shipping Corporation v Joseph Rank Ltd [1956] 3 All ER 683; [1957] 1 QB 267 at 286. "One must have regard to the language used and to the scope and purpose of the statute": ; Archbolds (Freightage) Ltd v S Spanglett Ltd [1961] 1 All ER 417; [1961] 1 QB 374 at 390. One consideration that has been regarded as important in a great many cases, of which ; Cope v Rowlands (1836) 2 M & W 149; 150 ER 707 is a notable example, is whether the object of the statute - or one of its objects - is the protection of the public. An antithesis is commonly suggested between an intention to protect the public, and an intention simply to secure the revenue, and it is said that when the former intention appears the contract must be taken to be prohibited, whereas if the intention is only to protect the revenue the statute will not be construed as imposing a prohibition on contracts. The question whether the statute was passed for the protection of the public is one test of whether it was intended to vitiate a contract made in breach of its provisions, but I am with respect in full agreement with the views expressed in ; St John Shipping Corporation v Joseph Rank Ltd [1957] 1 QB at 287 and ; Shaw v Groom [1970] 1 All ER 702; [1970] 2 QB 504 at 518 that it is not the only test. It would be contrary to reason and principle to allow one circumstance to override all other considerations in the interpretation of a statute. As Devlin J said in ; St John Shipping Corporation v Joseph Rank Ltd, supra, at 287: "The fundamental question is whether the statute means to prohibit the contract. The statute is to be contrued in the ordinary way: one must have regard to all relevant considerations and no single consideration, however important, is conclusive": see also ; Shaw v Groom [1970] 2 QB at 523.
To similar general effect, were the observations of Mason J (at 423):
The principle that a contract, the making of which is expressly or impliedly prohibited by statute, is illegal and void is one of long standing but it has always been recognized that the principle is necessarily subject to any contrary intention manifested by the statute. It is perhaps more accurate to say that the question whether a contract prohibited by statute is void is, like the associated question whether the statute prohibits the contract, a question of statutory construction and that the principle to which I have referred does no more than enunciate the ordinary rule which will be applied when the statute itself is silent upon the question. Primarily, then, it is a matter of construing the statute and in construing the statute the court will have regard not only to its language, which may or may not touch upon the question, but also to the scope and purpose of the statute from which inferences may be drawn as to the legislative intention regarding the extent and the effect of the prohibition which the statute contains.
50 Of particular relevance to this appeal were the observations of Jacobs J (at 431):
If a statute imposes a positive obligation to make contracts in a certain way, a prohibition against making contracts in another way can be implied as a matter of construction and will be implied unless the purpose of the statutory requirement is merely to protect the revenue: Victorian Daylesford Syndicate Ltd v Dott [1905] 2 Ch 624.
For more recent High Court authorities see Nelson v Nelson (1995) 184 CLR 538 and especially at 551-552 and Fitzgerald v F J Leonhardt Pty Ltd (1997) 189 CLR 215. The principles discussed in Yango Pastoral Company Pty Ltd v First Chicago Australia Ltd (supra) when considered in relation to the legislative scheme in Pt VID, point to the conclusion expressed above. That is, the Act prohibits the alterations of rights and obligations concerning a matter dealt with by an AWA if it might disadvantage the employee, by means other than those provided in the Act. Any agreement purporting to alter rights and obligations in this way would be unenforceable.
51 Before turning to the particular circumstances of this appeal, one further comment should be made about the legislative scheme. As noted earlier the essential characteristic of an AWA is that it is an agreement "that deals with matters pertaining to the relationship between an employer and employee". A similar reference to matters was found in s 65 of the Conciliation and Arbitration Act 1904 (Cth) which concerned the relationship between awards made under that legislation and State laws. The section provided:
Where a State law, or an order, award, decision or determination of a State Industrial Authority, is inconsistent with, or deals with a matter dealt with in, an award, the latter prevails and the former, to the extent of any inconsistency or in relation to the matter dealt with, is invalid.
This section invited a comparison between awards (amongst other things) made under federal law and awards and other determinations made under State law and the matters each dealt with to determine inconsistency. The High Court has, on several occasions, considered the operation of this section or earlier versions of it. The most recent consideration (as the central issue raised in the proceeding) was in Metal Trades Industry Association v Amalgamated Metal Workers' and Shipwrights' Union (supra). The way the comparison should be made, and in particular, how the "matter" should be identified, was discussed by Mason, Brennan and Deane JJ in the following passage (at 649):
The critical question then is: What is the conduct or matter with which the relevant awards deal? For the effect of s 65 is to make the provisions of the awards exclusive in relation to that conduct or matter and thus to make it inconsistent for the law of a State to govern what is dealt with by the awards. The section contradicts the hypothesis that the award provisions are intended to operate side by side with the provisions of a State law dealing with that conduct or matter.
There are powerful reasons which support the approach which finds expression in s 65. General industry awards have steadily become more comprehensive in their reach, regulating in a detailed fashion the terms and conditions of employment. It is not uncommon now to find in a general industry award clauses setting out in detail rights and obligations of the parties under the contract of employment, particularly in relation to termination of employment. Moreover, an award is the final product of the complex process of conciliation and arbitration set in train by the service of a log of claims and its non-acceptance. It is a settlement, intended to be enduring, of the terms and conditions which are to govern the industrial relations of employers and employees in the industry to which the award relates. In this situation it is natural and convenient that the award should be regarded to the exclusion of State law, as expressing the relations of the parties governing the matters with which it deals. It would undermine the settlement embodied in the award if its provisions were to be disturbed by the operation of State law on matters with which it deals.
Of course it is inevitable that there are some matters with which a comprehensive general industry award fails to deal, either because the parties are content to accept the application of State law, eg workers' compensation, or because it has been considered that an award cannot validly deal with the matter, eg superannuation and pension benefits (v Hamilton Knight; Ex parte Commonwealth Steamship Owners Association (1952) 86 CLR 283, a decision which may require reconsideration in the future). The more difficult questions of inconsistency occur in this area. We shall return to it shortly.
These reasons led their Honours to take a fairly broad view of what was the matter dealt with by the industry award in question leading to the conclusion that a State law concerning employment protection on termination had no field of operation for employees covered by that industry award. The fact that awards are now limited to allowable matters: see s 89A, does not in our opinion, detract from this reasoning.
52 Similar reasoning to that adopted in Metal Trades Industry Association v Amalgamated Metal Workers' and Shipwrights' Union (supra), would lead to a similar conclusion in relation to AWAs. That is, what matters are dealt with by an AWA should not be viewed narrowly when determining its legal effect in relation to, amongst other things, State laws. However, if the matters an AWA deals with are not viewed narrowly for that purpose, there would be no apparent reason for treating more narrowly the matters an AWA deals with for the purpose of determining the circumstances in which contractual terms can be agreed between the employer and employee bound by an AWA without having to enter a variation agreement and having it approved.
53 This leads to a consideration of whether, in the present case, the bond agreement was an enforceable agreement. It might not be because the appellant's AWA provided in clause 1.4.3 that it could be varied in accordance with the Act. This clause may have limited the means of varying the AWA. The bond agreement may be an ineffective variation. A related question is whether the bond agreement constituted a variation which was ineffective by operation of the Act because the procedures under the Act for approval of a variation agreement were not followed.
54 The answer to the first question is caught up in the answer to the second. Clause 1.4.2 evinced an intention that the appellant's AWA dealt comprehensively with her terms and conditions of employment, even if the provisions left room for other terms and conditions of employment arising either by operation of law or further collateral agreement. At the very least this clause evinced an intention that the appellant's AWA dealt comprehensively with the matters addressed in the AWA. Training is dealt with in various ways. An employee could be required to undergo training: clause 1.5.2. Having regard to clause 2.4 and Part 5, there was a mutual commitment to the acquisition by the appellant of work-related skills. It may be accepted that the distinction was drawn in clause 5.1.3 to the acquisition of skills in a position to which the appellant was appointed (which was not as an officer on a Dash 8) and the acquisition of training for higher or alternative positions. Nonetheless, the appellant's AWA identified rights and obligations in relation to both types of training. The former type, necessary training, interacted with clause 6.13.1. That is, had the appellant refused to undergo necessary training her employment could be terminated. The latter type, training not required for the appellants appointed position, would not have created an entitlement in the appellant to a higher rate of pay unless it was completed and the skills obtained used in her employment. We should, at this point, indicate that we do not accept the submission of the respondent (and adopted by the learned Magistrate) that the expression "by agreement with us" in clause 5.1.3 allowed for a collateral bond agreement. Fairly clearly that clause was a reference to agreement about whether such training can be undertaken and is not directed to any collateral agreement, such as the bond agreement, concerning such training.
55 In addition, the appellant's AWA dealt with the circumstances in which the appellant's employment could be terminated. It conferred on the respondent a right to terminate the appellant's employment summarily in the circumstances specified in 6.13.1 or on notice in circumstances dealt with in 6.13.2 (subject to the procedures specified in that clause) or on notice otherwise: see 6.13.3. The appellant could terminate her employment on notice as provided in 6.13.4. The AWA did not qualify the appellant's right to terminate on notice other than providing for a forfeiture of pay if a minimum period of notice was not given. It certainly did not qualify the appellant's right to terminate by requiring the payment of an amount of the type referred to in the bond agreement. Nor did the AWA confer on the respondent a right to payment of such an amount in the event it dismissed the appellant summarily for serious and wilful misconduct or dismissed the appellant for failing to adequately carry out her duties and responsibilities in any position to which she was promoted (such as a Dash 8 pilot). The bond agreement did.
56 It appears to us that the bond agreement concerned aspects of the matters dealt with in both Part 5 and 6.13 of the appellant's AWA and it imposed an additional burden on the appellant. Accordingly to create the rights and obligations found in the bond agreement, it would have been necessary for the appellant and respondent to make a variation agreement and have it endorsed by the Employment Advocate. The failure of the parties to do so had the result that the bond agreement was unenforceable. The learned Magistrate erred in concluding it did.
