77 Their Honours then proceeded to amplify these comments at paras 170 to 176:
170 Section 106 does not give the Court power to make any orders if the contract in question is not demonstrated on the evidence to be unfair, as defined. That is what the section is concerned with. The conduct of parties to the contract is a relevant consideration, directed however to the determination of whether, and how, the contract rather than the conduct is, in the words of s105:
(a) unfair, harsh or unconscionable, or
(b) against the public interest, or
(c) provides a total remuneration that is less than a person performing the work would receive as an employee performing the work, or
(d) designed to, or does, avoid the provisions of an industrial instrument
171 It is the 'contract or arrangement, or any related condition or collateral arrangement' identified in the initiating summons which at the end of the day must be the subject of the relevant findings. This approach has often been stated by this Court, most recently perhaps in Bush Boake, in the context of the enactment of s109A of the Act, which is concerned with claims concerning unfair dismissal. It was there observed by the Full Court at p35:
'What emerges from the above authorities, we think, is the now settled view that s.106 (as with the previous s.88F of the 1940 Act and s.275 of the 1991 Act) is directed to an impugned contract of employment, whether existing or terminated, as to the fairness of its express or implied terms. Such unfairness will depend upon the facts of each particular case by focusing attention on the contractual relationship between a particular employer and employee and where the unfairness may arise from the terms of the contract itself, the surrounding circumstances and/or the manner of performance or operation of the contract. The section, we emphasise, is not concerned with re-establishing an employment relationship which has ended nor with compensating an employee for the loss of his employment contract. In other words, the section is properly concerned with the fairness of the terms of a contract of employment in its various respects and, if relevantly found to be unfair, to provide remedial relief by avoiding or varying the terms of that contract and to order the payment of money in connection with any contract so avoided or varied as is considered just in the circumstances of the case.'
172 It follows that where a complaint brought under s106 alleges that there has been unfair conduct which throws light upon the unfairness of a particular contract or arrangement, consideration must be given as to whether or not on the evidence, the contract falls within the statutory definition in s105. If the only complaint advanced in a case brought however, is that the conduct was unfair, it is difficult to see how a case under s106 could be made out, unless the particular conduct itself formed a part of an arrangement which is attacked under the section. No such case was sought to be established here.
173 Had the legislature intended that unfair conduct of itself would be sufficient to warrant the grant of relief under s106(5) of the Act, it is to be expected that the section would have said so expressly. It does not. Section 106(1) is concerned with unfair contracts, which are defined in the way in which we have already noted. Section 106(2) permits regard to be had to conduct and the other matters specified, in determining whether the contract in question is unfair. Section 106(2) does not, however, alter the need for a relevant finding, on the basis of evidence advanced, that the contract is one which falls within the definition of unfair contract. The decision in Dun is not authority for such a proposition.
174 The conclusion that a finding of unfair conduct is not sufficient for relief to flow under s106 is also supported by s106(5), which provides:
'(5) In making an order under this section, the Commission may make such order as to the payment of money in connection with any contract declared wholly or partly void, or varied, as the Commission considers just in the circumstances of the case.'
175 The language of this provision is similar to that of s88F of the Industrial Arbitration Act 1940, considered by the High Court in Brown v Rezitis (1971) 127 CLR 157. Barwick CJ observed as to the power to grant relief, at p165:
'The problem is to ascertain the limitation by construction of the section. It seems to me that the expression "in connection with" the contract or arrangement varied or avoided provides the necessary limitation as to the nature of the orders for payment of money which can be made and as to the person against whom they may be made. The draftsmanship of the section is inadequate: but I think the expressed intention as to this limitation can be derived from the sub-section read as a whole. Whilst it can be said that the expression "in connection with" is of wide import, it does emphasize the need for a close connection between the order made and the contract or arrangement varied or avoided. In my opinion, the power to make an order for the payment of money is at best no more than a power to make such an order as can reasonably be thought to have a real connection with the making, variation or avoidance of the contract or arrangement which has been varied or avoided. It may in truth be limited to a power to make an order for payment of money which has in fact a real connection with the making, variation or avoidance of the contract or arrangement. However, in either case it will, of course, include power to make an order for payment of money which has been paid or which was payable under the contract arrangements themselves. But, in my opinion, the power will not be limited to the making of such orders. It will extend to ordering the payment of money where the order on the larger view of the jurisdiction given by the sub-section could be considered to be appropriate to effect wholly or partially the restitution of the parties to their former position upon the variation or avoidance of the contract or arrangement.'
176 It follows that the relief which s106(5) contemplates, is relief flowing from the contract found unfair on the evidence and not merely any unfair conduct, which may or may not demonstrate the unfairness of the contract under review.
