39 We agree with contentions advanced by the unions that the "no extra claims" clauses of the health industry awards hereunder consideration operate so as to commonly bind all parties to the awards. The Full Bench in Re: NSW Education Employees (Non Continuing Contract Employment) Award (1998) 92 IR 239 at 245 expressed that conclusion thus:
In an industrial relations context the purpose of a no extra claims clause in a consent Award is that for the period of [sic]duration of the Award there will be no extra claims in favour of either side unless by agreement (emphasis added).
40 We also agree with the contentions advanced by the unions that a strict approach to the construction of the "no extra claims" provisions of industrial instruments should be adopted by the Commission. Wright J in Re Corrections Health Service Nurses' Award (1999) 90 IR 235 at 245 described the correct approach to construction in such cases (with a necessary caveat) as follows:
It should be emphasised that the Commission must ensure the integrity of not only its own wage fixing principles but also the strict observance of agreements and undertakings given by parties compliance with which, properly considered, are important and indeed essential to the integrity to the principles. Undertakings such as no extra claims provisions are crucial parts of the integrity of the system of wage fixation which occurs in the New South Wales system of industrial regulation. Therefore, nothing in this decision should be seen as providing any precedent for any other award or for any other part of the public sector. It is to be emphasised that this decision is arrived at in the light of the very particular and unusual set of circumstances of the present application. Any other consideration of such matters would necessarily depend on its particular facts.
In approaching the construction of no extra claims provisions, or provisions such as those contained in the Heads of Agreement, a strict approach of [sic] their construction should be applied consistent with the necessity of maintaining the integrity of the wage fixation principles. Nevertheless, a strict construction (that is, one which would be alert to ensure inappropriately brought claims do not proceed) does not require the Commission to ignore actual words used in the provision or to ignore a clear attempt by the parties to limit the terms of the commitment.
41 However, we do not consider the "no extra claims" clauses have the effect of constraining the determination by the Department to vary the private use of motor vehicles policy as proposed by the unions.
42 Each of the health industry awards forbid the making of "extra" or "further" claims during the life of each instrument. The expression "no extra claims" has an industrial meaning which may be altered, in particular instances, by the terms of any commitments given by the parties to the award (either by the terms of the award itself, or, as is often the case, by a preceding, inter-connected agreement recording the settlement of wage and conditions claims for a specified period of time).
43 The industrial meaning of the expression "no extra claims" was provided by the Full Bench in Re: Crown Employees (Teachers in Schools and Related Employees) Salaries and Conditions Award and another [2008] NSWIRComm 209 at [15] and [16], in a discussion as to the purpose of such provisions, as follows:
15 We would observe that no extra claims undertakings were adopted in the early 1980s in the federal Metal Industry Award 1971, as a device to prevent further award, but particularly over award, claims being made for an agreed period. Such undertakings have become a standard feature of wage fixing arrangements both at the federal and State level, especially through the mechanism of wage fixing principles. Commendably, employees, unions and employers have regarded their commitments to make no extra claims during the life of an award or agreement as solemn undertakings and rarely have they been breached. The commitments have been regarded as morally, as well as legally binding.
16 The purpose of no further claims commitments is to ensure certainty during the life of the relevant industrial instrument. That is to say, all matters agreed or arbitrated upon represented a settled arrangement for the term of the award or agreement. Depending on the terms of the commitment, employers could plan and act on the basis that during the life of the award or agreement, they would not incur any additional labour costs or industrial action in support of extra claims, nor would they be required to divert resources to dealing with such claims. Employees and their unions would not face claims to cut wages or alter to their detriment employment conditions prescribed by the award or agreement.
44 Whilst this passage and the judgment of the Full Bench in Re: NSW Education Employees (Non Continuing Contract Employment) Award (1998) 92 IR 239 (at 244) make clear that the union's contention as to the operation of the "no extra claims" provisions of the health industry awards may not be defeated merely because there is no specific provision in the subject awards for the private use of motor vehicles, we do not consider the determination made by the Department with respect to the rate charged for such usage may be described as a claim to reduce the employment conditions provided by award or agreement. Whilst, the ordinary literal meaning of the word 'claim' may contemplate any demand for something as due, or as to a right, in an industrial context the provisions do not have such a wide meaning or scope.
45 A determination by the Department to exercise a right to vary the private rate for motor vehicles in accordance with an agreement made with a particular employee could not, in our view, be described as a claim for the purposes of the "no extra claims" provisions of the health industry awards.
46 Whilst such a determination may, in appropriate cases, and subject to jurisdictional questions, be challenged on grounds of fairness or reasonableness, it neither has the effect of reducing an existing award entitlement nor advancing any new or additional claim or demand over those existing at the time the parties entered into the award provisions (or the pre-existing agreements in the form of the MOUs).
47 This same conclusion may be reached by reference to the "no extra claims" provisions of the MOUs. We have already indicated why recourse to those agreements is appropriate. To that may be added two considerations. First, in an industrial context the MOUs might, by their own force, serve to restrain claims made contrary to the "no extra claims" provisions of those agreements. Secondly, this approach to the construction of the health industry awards is consistent with the principle which requires the instrument to be considered in context: Fox v GIO Australia (2002) 56 NSWLR 512 at [46]. This has been applied by Full Benches in Campbells Cash & Carry Pty Ltd v National Union of Workers, New South Wales Branch (No 2) (2001) 53 NSWLR 393 and Metrocall Inc v Electronic Tracking Systems Pty Ltd (2000) 52 NSWLR 1. That context may include in the appropriate case reference to the source from which the award derived. As Burchett J (with whom Drummond J agreed) stated in Short v FW Hercus Pty Ltd (1993) 40 FCR 511 at 518-519 "when the expression was transplanted, it may have brought with it some of the soil in which it once grew, retaining a special strength and colour in its new environment. There is no inherent necessity to read it as uprooted and stripped of every trace of its former significance, standing bare in alien ground" (see also Zoological Parks Board of New South Wales v Australian Workers Union (2004) 135 IR 56 at [44]).
48 The appropriateness of this approach in the present case is reinforced by the provisions of the MOUs themselves, which provide that the agreements do not prevent the parties from instigating any proceedings with respect to the interpretation, application or enforcement of the MOUs or existing provisions of awards or other awards applicable to employees covered by the MOUs.
49 When considered in the light of the MOUs, the "no extra claims" commitments are said to prevent two types of claims or actions. First, the parties committed to precluding "claims for improved conditions of employment or demands made in respect of the employees covered by the Union and employed under the Awards". Secondly, the "no extra claims" provisions of MOUs provide "that no proceedings, claims or demands concerning wages or conditions of employment in respect of those employees will be instituted before the Commission or any other arbitral tribunal". (The provisions are very similar in each case with some minor but immaterial differences such as in the NSWNA's MOU which states that "no proceedings, claims or demands concerning wages or conditions of employment in respect of those employees will be instituted before the Commission or any other arbitral tribunal except as provided in the Leave Reserved Clause below".)
50 When seen in this context, we do not consider that it is conceivable that a proposed adjustment to the private rate of official motor vehicles is caught by the terms of the "no extra claim" clause of the health industry awards (or the MOUs). The amendment or alteration to the motor vehicle policy of NSW Health could not properly be described as a wage claim or claim for improved conditions of employment on any reasonable analysis. Nor do we consider that it could be described as a demand made in respect of employees because we consider that expression to be plainly devoted, both by its terms and in its context, to demands made by the unions for the advancement of conditions of employment for employees. In fact, there did not seem to be a strenuous argument put on behalf of the unions as to this first plank.
51 The same conclusion follows as to the second component of the "no extra claims" provisions. This outcome may be reached by one of two routes. At the simplest level the second component is excluded because there is nothing in the alteration of the policy, which involves the institution of proceedings before the Commission or any other arbitral tribunal as required by the second condition. The adjustment of the policy cannot meet that description.
52 Further, and secondly, we agree with the contention of the Department that the alteration of the private use policy does not constitute a proceeding, claim or demand concerning wages or conditions of employment covered by the various awards. The "no extra claims" provision is designed to ensure the agreement is reached in respect to matters already in the health industry awards (either as new or varied). Those matters will not be revisited during the life of the MOU save by agreement.
53 The alteration of the private use does not constitute any such thing and in any event the variation to the policy is proposed to be made in accordance with the existing terms of the policy and what it permits. In that respect, it cannot constitute a proceeding, claim or demand as the action is consistent with existing entitlement. We reiterate that we make no reference, in this respect, to the fairness or reasonableness of the adjustment proposed by the Department but merely as to whether the alteration of the policy is caught by the "no extra claims" commitment.
54 In our view, there is no substance to the claims made by the unions that the proposed alteration to the private use policy or the rate or formula described therein is precluded by the "no extra claims" provisions as found in either the relevant awards or the MOUs.
