The first issue - consideration
37 In Royal Botanic Gardens and Domain Trust v South Sydney City Council (2002) 240 CLR 45 at 52 [10] Gleeson CJ, Gaudron, McHugh, Gummow and Hayne JJ drew further on what Mason J had said in Codelfa Construction Pty Limited v State Rail Authority of New South Wales (1982) 149 CLR 337 at 352. They observed that it was appropriate to have regard to more than internal linguistic considerations in an agreement that the Court had to construe, and to consider the circumstances with reference to which the words in question were used and, from those circumstances, to discern the objective which the parties had in view.
38 In my opinion, the agreement reflects a detailed and complex attempt by the parties to it, and the persons bound by it, to balance a variety of interests and concerns. The cases to which I have referred, both those involving industrial agreements and other forms of contract, demonstrate that all such documents should be construed objectively, while having regard to the context in which they were made and the mutually known facts.
39 The provisions of cl 16.6.1 pointed objectively to a recognition that Qantas had to have the power, relevantly, to appoint pilots to a supervisory or training appointment on what it regarded as merit, despite the ordinary rule of seniority. That recognition was also reflected in cl 16.1.4, the differential rates of pay in cl 33 and specific provisions for pilots so appointed, made particularly in cl 25.
40 Moreover, as cl 33.1.1 expressly provided, a person appointed to a supervisory pilot's role would have "tenure". In its ordinary and natural meaning, "tenure" conveys or implies that the position to which it relates will have a particular duration, which is a common feature of employment, or tenure, arrangements. What is unusual in the present circumstances is that a pilot appointed to a supervisory role under the agreement, at the end of the period of tenure and without being demoted, will simply resume his or her role in the pilot's existing category which will then be at a lower rate of pay and in different working conditions from that which applied during the period of tenure. Moreover, the agreement reflected that the period of tenure of a person appointed to a supervisory role would be determined principally by Qantas, as part of a separate side agreement with the relevant pilot. The agreement also provided that such a pilot not only would have to be appointed by Qantas, but also approved by CASA, as statutory regulator, to act in that role.
41 Those factors suggest that a reasonable person in the position of the parties to the agreement would have understood that a pilot would be appointed to a supervisory role under cll 16.6.1, 25 and 33 for a specific period of tenure in accordance with the terms of his or her particular appointment.
42 It would be an odd result if, as a result of other circumstances, a pilot who happened to be more senior than the supervisory pilot, in effect, could cause the termination of the supervisory pilot's separate contract with Qantas that they had entered into in accordance with cll 16.6.1, 25 and 33 that supplemented that in the agreement: cf Concut Pty Ltd v Worrell (2000) 176 ALR 693 at 698-699 [18]-[22] per Gleeson CJ, Gaudron and Gummow JJ; Commonwealth Bank of Australia v Barker (2014) 253 CLR 169 at 182-183 [16] per French CJ, Bell and Keane JJ; Cohen v iSoft Group Pty Ltd (2013) 298 ALR 516 at 526-527 [35]-[38] per Rares, Cowdroy and Kerr JJ. That separate contract conferred a specific period of tenure in the supervisory role. Moreover, if a more senior pilot could displace a supervisory pilot not included in the list of names in cl 18.1.12(c)(iii) there would be a further consequence that Qantas, as the employer, would have to appoint someone else to the supervisory role that it did not consider to be surplus at the base and then to train or retrain the replacement and to obtain the approval of CASA for that person. It would be even more odd if Qantas had to select the new supervisory pilot from the new pool of pilots at the base, none of whom had the same merit in Qantas' eyes as the pilot selected on merit under cl 16.1.1 who was displaced.
43 In L Schuler AG v Wickman Machine Tool Sales Ltd [1974] AC 235 at 251, Lord Reid said (see also Zhu v Treasurer of New South Wales (2004) 218 CLR 530 at 559 [82] per Gleeson CJ, Gummow, Kirby, Callinan and Heydon JJ):
The fact that a particular construction leads to a very unreasonable result must be a relevant consideration. The more unreasonable the result the more unlikely it is that the parties could have intended it, and if they do intend it the more necessary it is that they shall make that intention abundantly clear. (emphasis added)
44 The structure of cl 18.1.12 commences with a state of facts that can only arise when Qantas has made a determination that there are too many pilots at a base. That determination generates a process under cl 18.1.12 that a reduction in numbers at the base is required. The number to be reduced is the surplus referred to in the clause. A reasonable person in the position of the parties would have understood that Qantas had to make a determination of the number of pilots who were surplus, based on an assessment of its own commercial and operational requirements and interests. That calculation depended on how many, and which, pilots Qantas decided that it needed to be based at a particular place, performing particular work.
45 Nonetheless, the agreement also recognised that if numbers of pilots had to be reduced, individuals could be affected adversely and that this could occur in a variety of ways, including, if worst came to worst, the creation of redundancies under cl 15.9. Thus, the structure of cl 18.1.12 commenced with the requirement that, before Qantas reduced numbers, it had to consult with the Association and consider all reasonable alternatives. The succeeding subclauses dealt progressively with situations in which the choices available to the persons affected would become more and more limited.
46 Clause 18.1.12(b) provided that, first, it was subject to cl 18.1.12(a) and, secondly, where there were vacancies in the same category at another base and there would be no change in the overall pilot numbers in the category across all bases, then Qantas had to seek letters of preference from its pilots and, following the order of seniority, award a transfer of bases to the most senior pilot in the relevant category and, if that process resulted in residual vacancies at other bases, Qantas had to repeat the steps in cl 18.1.12(b). In effect, the intention of cl 18.1.12(b) was that pilots selected as surplus in the same category, in the order of their seniority, would be able to transfer between bases as they preferred. Clearly enough, a supervisory pilot in a category affected, who was happy in his or her position, would not need to be involved in the movement between bases under cl 18.1.12(b).
47 Clause 18.1.12(c) operated subject to cl 18.1.12(a) and (b), so that it could only be operative when the processes contemplated in subcll (a) and (b) had been exhausted. Importantly, cl 18.1.12(c) was structured to reflect that the process it contemplated had resulted from a management imperative. That is because the subclause commenced by requiring Qantas to promulgate particular items of information at least 30 days prior to a reduction in numbers at a base that would be achieved in accordance with the mechanisms provided in cl 18.1.12(d) and (e). The first step required the promulgation to state the number and category of surplus pilots (cl 18.1.12(c)(i)). If cl 18.1.12(c)(iii) had the meaning that the Association contended for, the persons who comprised the relevant number of most junior pilots in a category would have been obvious to all at the base from the information required to be given by cl 18.1.12(c)(i).
48 I am of opinion that cl 18.1.12(c)(iii) conveyed, in its natural and ordinary meaning, that Qantas had to state the names of the pilots at the base whom it had identified as surplus pilots in the relevant category. The words "affected by the surplus" did not qualify only the base, but referred to the individuals in the category to whom the promulgation applied.
49 It would be an odd result if cl 18.1.12(c)(iii) automatically applied to a supervisory pilot at a base by reason of his or her seniority, even though Qantas had selected that pilot under cl 16.6.1 to fulfil a role for a tenure period, whom it did not regard as surplus to its requirements for that base. I am of opinion, unless Qantas intended that a supervisory pilot was surplus and should be relocated, that the agreement did not require Qantas to disrupt its pilot training operation at the affected base by having to train, retrain or transfer a new supervisory pilot. A reasonable person in the position of the parties at the time that the agreement was made would have known that any replacement supervisory pilot had to qualify for approval by CASA and to be of a standard that met Qantas' needs in circumstances where it previously had selected the displaced pilot on merit and not by his or her seniority.
50 The Association's argument, if accepted, would make the seniority tail wag the dog of Qantas' right to select a supervisory pilot on merit under cl 16.6.1 to fill a tenured position for which the agreement made specific provision in cll 25 and 33. Qantas selected those pilots on merit to train, not just the particular officers who may be at the same base, but also any other pilots Qantas wished to have trained. Moreover, the Association's argument that the expression "affected by the surplus" qualified only the words "the base" or "the category at the base", and not the individuals who actually would be affected, in my opinion, is not a natural and ordinary meaning of that expression as used in cl 18.1.12. Indeed, cl 18.1.12(e) commenced with the chapeau, "A pilot included in the promulgation issued under [sic] 18.1.12(c) may, subject to clause 16 …" and then gave that pilot a choice of three options. That chapeau appeared to recognise that an individual would be named as being "affected by the surplus". Clause 18.1.12 was drafted on the basis that, having exhausted all other alternatives, Qantas had arrived at a decision that it had a surplus number of pilots in a particular category at a particular base and it needed to reduce that surplus.
51 In my opinion, it would be a strained and unrealistic construction to read cl 18.1.12 as requiring the inclusion, in such a surplus in a category, of a supervisory pilot whom Qantas had selected on merit, and retained on a tenure, to fulfil a different role for which the agreement made specific provision in cll 16.6.1, 25 and 33. The agreement provided differently for the tenure of particular classes of supervisory pilots. Clause 25.5.1, itself, did not refer to tenure, whereas cl 25.2.4 did in relation to a fixed tenure of at least two years for, first, the head of training and checking and, secondly, pilots, being captains, who had been appointed as type rated examiners (TRE) A and B. Nonetheless, cl 33.1.1 provided that a TRI-FO pilot would have tenure, the length of which was at the discretion of Qantas and the particular pilot concerned.
52 The purpose of the agreement giving Qantas the right, under cl 16.6.1, to select pilots to fulfil a supervisory role would be defeated if it were not able to segregate, in its promulgation of names under cl 18.1.12(c)(iii), those pilots from others whom it considered to be surplus at a base. I am of opinion that cl 18.1.12 did not subject Qantas' own internal management structure and its supervisory pilots to a situation in which the seniority system necessitated that a more senior pilot could displace a supervisory pilot with tenure, thereby causing Qantas, first, to be liable for, perhaps, a breach of contract in that situation, and secondly, to reorganise its arrangements in the base or location at which its previously selected, and now displaced, supervisory pilot would need to be replaced. In my opinion, that construction does not make any industrial or commercial sense.
53 For those reasons, I reject the Association's argument that Qantas breached the terms of cl 18.1.12(c) by nominating 16 pilots without including in the notice issued on 8 September 2015 the two supervisory pilots, being First Officers Taylor and McDonogh.
