Reasons for Decision
1 The Western Australian Prison Officers’ Union (WAPOU) and the Minister for Corrective Services (Minister) are in dispute about the correct interpretation of cl 48.2 of the Department of Justice Prison Officers’ Industrial Agreement 2020 (Prison Officers’ Agreement). WAPOU filed an application for an interpretation of cl 48.2 under s 46 of the Industrial Relations Act 1979 (WA) (IR Act).
2 WAPOU then informed the Commission and the Minister that it had become aware of the similarity between cl 48.2 of the Prison Officers’ Agreement and cl 19(5) of the Public Service Award 1992 (Public Service Award).
3 In circumstances where the Public Service Award applies to a large number of public sector employees, the Commission invited the Civil Service Association of Western Australia Incorporated (CSA) and the Minister for Industrial Relations to consider whether they wished to file an application to intervene in application APPL 15 of 2022.
4 The Minister for Industrial Relations did not wish to intervene.
5 The CSA seeks to intervene. It argues that it has sufficient interest to intervene because its industrial instruments cover approximately 39,723 government officers, the wording in cl 48.2 of the Prison Officers’ Agreement is almost identical to the wording in cl 19.5 of the Public Service Award, and there are a further nine public sector industrial instruments to which the CSA is a party that also contain clauses with similar wording. Finally, the CSA argues that application APPL 15 of 2022 arises out of a disciplinary matter dealt with under Part 5 of the Public Sector Management Act 1994 (WA) (PSM Act), which applies to its members who are public service officers, juvenile custodial officers and social trainers.
6 WAPOU argues that the CSA should be granted leave to intervene because ‘there is a serious question of fact and law’ about whether a decision in application APPL 15 of 2022 would affect the interpretation of the other industrial instruments the CSA has identified, and because there would be a risk of multiple proceedings ‘if this matter is not decided in the current application’.
7 The Minister objects to the CSA being granted leave to intervene for reasons including that the proper approach to the construction of industrial agreements is not the same as the proper approach to the construction of awards. The proper construction of the Prison Officers’ Agreement can have no impact upon the proper construction of the Public Service Award or any other instrument referred to in the CSA’s application to intervene. The Minister says that the CSA does not have sufficient interest in application APPL 15 of 2022 to warrant it being granted leave to intervene.
8 The parties agreed that the Commission should decide the CSA’s application to intervene on the papers.
What must I decide?
9 I must decide whether the CSA has sufficient interest in the matter to be granted leave to intervene in application APPL 15 of  2022, and if so, on what terms.
Legal principles
10 The Commission’s power to grant leave to intervene is set out in s 27(1)(k) of the IR Act:
27. Powers of Commission
Except as otherwise provided in this Act, the Commission may, in relation to any matter before it —

(k) permit the intervention, on such terms as it thinks fit, of any person who, in the opinion of the Commission has a sufficient interest in the matter; and
11 The Full Bench considered s 27(1)(k) of the IR Act most recently in Australian Workers' Union, West Australian Branch, Industrial Union of Workers & others v (Not Applicable) [2016] WAIRC 00966 (AWU v NA) from [17]-[21]:
[17] The principles for the Commission to consider when determining whether to exercise its discretion to allow a person to intervene in proceedings pursuant to its power to do so under s 27(1)(k) of the IR Act, in particular the determination whether a person has, in the opinion of the Commission, a sufficient interest in a matter that that person should be heard, were considered by Sharkey P in Gairns v The Royal Australian Nursing Federation Industrial Union of Workers, Perth (1989) 69 WAIG 2343. In Gairns the substantive application was an application brought before the President's original jurisdiction under s 66 of the IR Act for an interpretation of union rules. The federal nursing union, the Australian Nursing Federation, sought intervention in the proceedings. So, too, did federal and state Academic Unions. President Sharkey found that the most helpful dissertation of principles relating to intervention was set out in Re Ludeke; Ex parte Customs Officers' Association of Australia, Fourth Division [1985] HCA 31; (1985) 155 CLR 513; (1985) 13 IR 86.
[18] In Ludeke, the matter before the High Court was an application by the Customs Officers' Association of Australia, Fourth Division to make absolute an order nisi for a prerogative writ to quash an order made by Justice Ludeke that leave be granted to the Administrative and Clerical Officers' Association, Australian Government Employment (ACOA) to intervene in the matter subject to limitation on certain questions it raised in its submissions in a demarcation dispute between that union and the ACOA. Chief Justice Gibbs at (519) - (520), with whom Dawson J agreed, observed:
The critical question is whether the prosecutor will be denied natural justice if it is allowed to intervene in ACOA's application only to the limited extent allowed by Ludeke J. It may be said immediately that it is clear that notwithstanding the wide discretion in matters of procedure given to the Commission by s. 40(1) of the Act, the Commission is bound to observe the rules of natural justice: Reg. v. Commonwealth Conciliation and Arbitration Commission; Ex parte Angliss Group ((1969) 122 C.L.R. 546, at p. 552); Reg. v. Moore; Ex parte Victoria ((1977) 140 C.L.R. 92, at pp. 101-102); Reg. v. Isaac; Ex parte State Electricity Commission (Vict.) ((1978) 140 C.L.R. 615, at p. 620). That means that a person whose rights will be directly affected by an order made by the Commission must be given a full and fair opportunity to be heard before the order is made. That requirement will not necessarily be satisfied if the Commission relies only on the fact that the person concerned has been heard on the same question by the same member of the Commission on a previous occasion. In general, the rules of natural justice are not satisfied unless the opportunity to be heard is afforded in the proceeding in question, although the fact that there had been an earlier hearing would be relevant in determining what constituted a full opportunity to be heard. However, natural justice does not require that everyone who may suffer some detriment as an indirect result of an order of the Commission is entitled to be heard before the order is made. Orders made by the Commission may affect many members of the community who are not parties to the proceedings in question but that does not mean that any member of the community who will be indirectly affected by an order of the Commission has a right to be heard in those proceedings. It has been held that a person who is not a party to a dispute, but who may nevertheless be affected, indirectly and consequentially, by an order made in settlement of the dispute is not entitled to be heard before the matter is determined: Reg. v. Moore; Ex parte Victoria; Reg. v. Isaac; Ex parte State Electricity Commission (Vict.).
[19] From these observations of Gibbs CJ in Ludeke, the following principles emerge:
(a) Every person whose rights will be directly affected by an order must be given a full and fair opportunity to be heard; and
(b) The principles of natural justice do not require that everyone who may suffer a detriment as an indirect result of an order or who is indirectly affected is entitled to be heard before the order is made.
[20] Justice Mason in Ludeke made similar observations. He observed that an interest which in its nature is inadequate to support intervention in legal proceedings in a court may be sufficient to support intervention in a matter of industrial arbitration before the Commission (523). His Honour found that if an organisation has a substantial interest sufficient to sustain an application to the court for prohibition then, generally speaking, it is desirable that the Commission should recognise that interest, subject to discretionary considerations, as a basis for intervention (525). In making this observation, his Honour had regard to the decision in R v Holmes; Ex parte Public Service Association (NSW) [1977] HCA 70; (1977) 140 CLR 63 where it was found that where the prosecutor had relevant coverage under its eligibility rule there could be no doubt that it had a substantial interest sufficient to sustain its intervention and that a lack of coverage would result in the prosecutor's interest being much more tenuous (525). Justice Mason in Ludeke also said (527):
Indeed, the principal object of intervention is to ensure that all interested parties will participate in a single resolution of a controversy instead of being relegated to a resolution of the controversy in several proceedings. It is the attainment of this object that justifies intrusion into the litigant's right or interest in pursuing his proceedings as he chooses to constitute them.
[21] Justice Brennan said that he generally agreed with the judgment of the Chief Justice. His Honour then went on to add that in determining whether a repository of a statutory power is bound to hear a person who is not directly involved in proceedings regard must be had (528):
to all the circumstances of the case, including the language of the statute, the nature of the power and of the body in which the power is reposed, the nature of the proceedings, the procedural rules that govern the proceedings (especially any provision for intervention by a person not directly involved in them), the interests which are likely to be affected, directly or indirectly, by the exercise of the power and the stage the proceedings have reached when the repository of the power learns of those interests. Generally speaking, a decision that will affect adversely a person's legal rights or his proprietary or financial interests or his reputation ought not to be taken without first giving him an opportunity to be heard provided such an opportunity can be reasonably given (F.A.I. Insurances Ltd. v. Winneke ((1982) 151 C.L.R. 342, at pp. 411-412)), even if that person is not directly involved in the proceedings which lead to the making of the decision: cf. Reg. v. Town and Country Planning Commissioner; Ex parte Scott ([1970] Tas. S.R. 154, at pp. 182-187; 24 L.G.R.A. 108, at pp. 137-141). But that is not an absolute rule.
CSA’s submissions
12 The CSA says its right to intervene comes from statute. The Commission does not have inherent jurisdiction to permit intervention so the Commission’s decision about the CSA’s application to intervene must be made in the statutory context. The CSA says that the Minister is applying the wrong test.
13 The CSA says that when deciding applications for leave to intervene, the Commission ‘has generally applied Re Ludeke; Ex Parte Customs Officers Association of Australia [1985] HCA 31 (Ludeke), which followed the reasoning in Australian Railways Union v Victorian Railway Commissioners [1930] HCA 52.
14 In particular, the CSA draws the Commission’s attention to Mason J’s reasoning at 331 in Ludeke, where he says:
I think we would be wise to exercise it by allowing only those to be heard who wish to maintain some particular right, power or immunity in which they are concerned’, ‘an interest which in its nature is inadequate to support intervention in legal proceedings in a court may be sufficient to support intervention in a matter of industrial arbitration before the Commission’ and that ‘the principal object of intervention is to ensure that all interested parties will participate in a single resolution of a controversy instead of being relegated to a resolution of the controversy in several proceedings.
15 The CSA also relies on [19]-[21] of AWU v NA. It says that the interpretation of clauses with similar wording in industrial instruments that the CSA is a party to ‘is a “particular right, power or immunity” as required by [AWU v NA] because it is an industrial right that applies to our members’.
16 I understand the effect of the CSA’s submission to be that not only is the CSA a party to the Public Service Award, but it is also a party to at least nine other industrial instruments that have provisions with wording similar to cl 48.2 of the Prison Officers’ Agreement:
a) Government Officers Salaries, Allowances and Conditions Award 1989;
b) Juvenile Custodial Officers Award;
c) Government Officers (Social Trainers) Award 1988;
d) Education Department Ministerial Officers Salaries, Allowances and Conditions Award 1983;
e) Department of Communities (CSA) Family Resource Workers, Welfare Assistants and Parent Helpers Award 1990;
f) Government Officers (Insurance Commission of Western Australia) Award 1987;
g) Parliamentary Employees Award 1989;
h) WA Health CSA Dental Technicians (Dental Health Services) Award 2016; and
i) Dental Health Services – Dental Officers – CSA Industrial Agreement 2021.
17 In total, the CSA says that it is a party to industrial instruments that collectively cover 39,723 employees. The CSA argues ‘the particular higher duties clauses have evolved in the public sector through flow-on, and so any decision on their meaning will be persuasive for similar clauses.’
18 Further, the CSA says that application APPL 15 of 2022 arose out of a dispute about the effect of a demotion under Part 5 of the PSM Act. This section applies to public service officers, juvenile custodial officers and social trainers.
19 The interpretation declared in application APPL 15 of 2022 ‘may impact as to how the clauses in the CSA’s instruments are interpreted, especially where the industrial contexts are similar’. Despite ‘any small differences in language or industrial context’ the CSA’s interest is ‘substantial enough to warrant intervention’. It says ‘[t]he particular higher duties clauses have evolved in the public sector through flow-on, and so any decision on their meaning will be persuasive for similar clauses’.
20 The CSA says that the ‘interpretative exercise’ for industrial agreements and awards is not as different as the Minister says. In both cases, the Commission must begin with the plain meaning of the words. To not grant the CSA leave to intervene in this matter would be ‘contrary to the objective of preventing repetitive litigation on similar clauses and future interventions’. Whether the industrial context of the industrial instruments set out at above is similar to the industrial context of the Prison Officers’ Agreement is a question of fact and law ‘for which the CSA should be allowed to make submissions on as the CSA has established sufficient interest in the answer to that question’.
21 For these reasons, the CSA says it has sufficient interest in the matter and should be granted leave to intervene.
WAPOU’s submissions
22 WAPOU’s submissions are brief. It says that s 27(1)(k) of the IR Act ‘confers extensive discretion on the Commission to permit intervention, and there is nothing in the statute to support limiting the discretion by reference to considerations that may apply in legal proceedings in court’.
23 It says the primary question is whether the intervener has ‘sufficient interest’ and it is not an absolute rule that it must be a direct interest: Gairns v Royal Australian Nursing Federation Industrial Union of Workers (1989) 69 WAIG 2343 at 2347 per Sharkey P.
24 The nature of the proposed intervener’s interest need not reach the level required to permit intervention in court proceedings: AWU v NA at [20]. The principal object of allowing intervention is to resolve disputes in a single proceeding. An intervener may be establish a sound basis for intervention on this point alone: AWU v NA at [20].
25 The CSA is said to have identified ‘many industrial instruments which contain similar language to the provision the subject of these proceedings, which were made in a similar industrial context’. There is a question of fact and law about whether a decision on the current application ‘may influence the interpretation of instruments that the CSA has identified’ and there is a ‘significant risk of multiple proceedings’. The Commission should grant the CSA leave to intervene in this application.
Minister’s submissions
26 The Minister opposes the CSA’s application for leave to intervene. He says that the proper approach to the construction of industrial agreements is not the same as the proper approach to the construction of awards. Awards are subsidiary legislation made by the Commission or Public Service Arbitrator but agreements are made between negotiating parties and registered by the Commission or Public Service Arbitrator. The proper approach to construing industrial agreements fixes upon the proper approach to construing contracts, which is to determine the objective intention of the parties as understood from the text in the context in which it appears. It is not relevant what the parties objectively intended in the awards referred to by the CSA.
27 The proper construction of industrial agreements turns upon the objective intention expressed in the text and the context in which it appears. The industrial context (public sector employment) is part of the context of the text, but each industrial instrument will also have its own more specific context, for example the specific employees covered by that industrial instrument. Importantly, ‘each instrument will have a different context as far as the balance of the text of the instrument is concerned’. The Prison Officers’ Agreement stands alone because it does not have the same textual context as any of the industrial instruments referred to by the CSA.
28 Parties to industrial instruments that are not the subject of application APPL 15 of 2022 can make other applications, including under s 46 of the IR Act, about the proper construction of those industrial instruments.
29 Further, the CSA has not provided a summary of what it proposes to say in intervention. It is possible that the CSA could submit that the Prison Officers’ Agreement should be construed differently to the industrial instruments that it says has clauses with similar wording to cl 48.2. For example, this could be because of the effect of admissible evidence that the CSA might try to lead about the construction of those industrial instruments.
30 In those circumstances, the CSA should not be granted leave to intervene.
31 The Minister also submits that if the CSA is granted leave to intervene, it should be required to file an outline of the submissions it intends to make as an intervener in relation to application APPL 15 of 2022. Further, if the CSA is granted leave to intervene, then each and every employer party to the industrial instruments referred to by the CSA should properly be invited to intervene. There should also be an assessment of other instruments in the State industrial relations system to see whether there are any other industrial instruments with similar provisions. If there are, the parties to those instruments should also be invited to intervene.
Consideration
32 Having considered the application to intervene and the submissions from the CSA, WAPOU and the Minister, I am not persuaded that the CSA has sufficient interest in this matter.
33 Under section 27(1)(k) of the IR Act, the Commission may permit intervention if the Commission considers that the person has a sufficient interest in the matter.
34 Applying the reasoning in Ludeke, adopted by the Full Bench in AWU v NA, if the CSA’s rights or its members’ rights would be directly affected by the order/s sought in application APPL 15 of 2022 then clearly the CSA would have sufficient interest in this matter to justify granting leave to intervene.
35 The Prison Officers’ Agreement does not apply to the CSA or its members. Declaring the true interpretation of that agreement would not directly affect the rights of the CSA or its members.
36 That cl 19(5) of the Public Service Award may be ‘almost identical’ to cl 48(2) of the Prison Officers’ Agreement does not mean that the CSA has a sufficient interest in this matter. The proper approach to the construction of awards is not identical to that of industrial agreements.
37 The principles that apply to the interpretation of industrial agreements are the principles that apply to interpretation of contracts. The Full Bench said at [21]-[23] of Fedec v Minister for Corrective Services [2017] WAIRC 00828; (2017) 97 WAIG 1595:
[21] The approach that is to be applied when interpreting an industrial agreement is well established. This is:
(a) Industrial agreements are usually not drafted with careful attention to form by persons who are experienced in drafting documents that have legal effect.
(b) The task of construction of an industrial agreement is to be approached in a way that allows for a generous construction: City of Wanneroo v Holmes [1989] FCA 369; (1989) 30 IR 362.
(c) Industrial agreements are made for industries in light of the customs and working conditions of each industry and must not be interpreted in a vacuum divorced from industrial realities: George A Bond & Co Ltd (in liq) v McKenzie [1929] AR (NSW) 498; City of Wanneroo v Holmes (378 - 379) (French J).
[22] The general principles that apply to the construction of contracts and other instruments also apply to the construction of an industrial agreement. In Re Harrison; Ex parte Hames [2015] WASC 247, Beech J said [50] - [51]:
The general principles relevant to the proper construction of instruments are wellknown. In summary:
(1) the primary duty of the court in construing an instrument is to endeavour to discover the intention of the parties as embodied in the words they have used in the instrument;
(2) it is the objectively ascertained intention of the parties, as it is expressed in the instrument, that matters; not the parties' subjective intentions. The meaning of the terms of an instrument is to be determined by what a reasonable person would have understood the terms to mean;
(3) the objectively ascertained purpose and objective of the transaction that is the subject of a commercial instrument may be taken into account in construing that instrument. This may invite attention to the genesis of the transaction, its background and context;
(4) the apparent purpose or object of the relevant transaction can be inferred from the express and implied terms of the instrument, and from any admissible evidence of surrounding circumstances;
(5) an instrument should be construed so as to avoid it making commercial nonsense or giving rise to commercial inconvenience. However, it must be borne in mind that business common sense may be a topic on which minds may differ; and
(6) an instrument should be construed as a whole. A construction that makes the various parts of an instrument harmonious is preferable. If possible, each part of an instrument should be construed so as to have some operation (Electricity Generation Corporation v Woodside Energy Ltd [2014] HCA 7; (2014) 251 CLR 640 [35] (French CJ, Hayne, Crennan & Kiefel JJ); Kidd v The State of Western Australia [2014] WASC 99 [122]; Red Hill Iron Ltd v API Management Pty Ltd [2012] WASC 323 [106] - [112]; Primewest (Mandurah) Pty Ltd v Ryom Pty Ltd [2014] WASCA 28 [55] (Martin CJ, Pullin & Murphy JJA agreeing)).
These general principles apply in the construction of an industrial agreement (Director General, Department of Education v United Voice WA [2013] WASCA 287 [18] - [20] (Pullin J, Le Miere J agreeing), [83] (Buss J)). The industrial character and purpose of an industrial agreement is part of the context in which it is to be construed (Amcor Ltd v Construction, Forestry, Mining & Energy Union [2005] HCA 10; (2005) 222 CLR 241 [2] (Gleeson CJ and McHugh J); Director General v United Voice [81]; see also Amcor v CFMEU 66 (Kirby J), 129 - 130 (Callinan J)).
[23] To these principles, the following observations made by Pullin J in Director General, Department of Education v United Voice WA [2013] WASCA 287; (2013) 94 WAIG 1 [18] - [19] should be added:
The Agreement has to be construed to determine what the intention of the parties was at the time the Agreement was entered into. This has to be determined by ascertaining what a reasonable person would have understood the words of the Agreement to mean taking into account the text, the surrounding circumstances known to the parties and the purpose and object of the transaction: Toll (FGCT) Pty Ltd v Alphapharm Pty Ltd [2004] HCA 52; (2004) 219 CLR 165 [40]; Pacific Carriers Ltd v BNP Paribas [2004] HCA 35; (2004) 218 CLR 451 [22].
Surrounding circumstances may only be taken into account if the ordinary meaning of the words used by the parties is ambiguous or susceptible of more than one meaning: Codelfa Construction Pty Ltd v State Rail Authority of New South Wales [1982] HCA 24; (1982) 149 CLR 337, 352; McCourt v Cranston [2012] WASCA 60 [23].
38 I accept that there may be circumstances where a person has sufficient interest in a matter, even where their interest is indirect and would not support intervention in legal proceedings in a court.
39 The CSA seems to argue that it should be granted leave to intervene so it can be heard at the substantive hearing about whether the interpretation of the Prison Officers’ Agreement could impact the awards mentioned by the CSA. That submission is misconceived. The issue of whether the interpretation of the Prison Officers’ Agreement could impact the awards and industrial agreement set out at [16] is said to be the basis for the CSA’s interest in this matter. The CSA has had an opportunity to be heard about that. The CSA chose to be heard on the basis of its written submissions.
40 In my view, that other awards and one industrial agreement to which the CSA is a party contain clauses with similar wording to cl 48.2 of the Prison Officers’ Agreement is too tenuous a connection to amount to a sufficient interest in this matter. The Commission’s task in interpreting the true meaning of a clause in an industrial agreement involves considering the objective intention of the parties from the text in the context in which it appears. Industrial agreements each have their own textual context. It therefore does not follow that an interpretation of cl 48.2 of the Prison Officers’ Agreement in this matter would affect the interpretation of a clause in a different industrial agreement or award, even if that clause is similarly worded.
41 Accordingly, I do not consider that the ‘industrial rights’ of the CSA’s members under other industrial instruments would suffer, even as an indirect result of an order, if the CSA is not permitted to intervene in this matter. The rights and interests that may be affected by an order in this matter are those of WAPOU, its members and the Minister. In any event, to the extent that the CSA and its members could be indirectly affected by an order made in this matter, such an interest is not substantial. It is not sufficient to entitle the CSA to be heard before the order is made.
42 Contrary to the submission of WAPOU and the CSA, allowing the CSA to intervene in this matter would not have the effect of avoiding multiple proceedings. This is because a resolution in this matter could not be said to settle other disputes about the interpretation of similarly worded clauses in other awards or industrial agreements. A dispute about the interpretation of a clause in an industrial agreement can only be resolved by considering the objective intention of the parties from the text in the context of that particular industrial agreement. Intervention in this matter would not lead to the single resolution of a controversy. It would not settle a dispute about the interpretation of a different industrial agreement or award.
43 As noted by Gibbs CJ in Ludeke at 520, ‘Orders made by the Commission may affect many members of the community who are not parties to the proceedings in question but that does not mean that any member of the community who will be indirectly affected by an order of the Commission has a right to be heard in those proceedings.’ That application APPL 15 of 2022 may have arisen out of a dispute in relation to a disciplinary matter dealt with under Part 5 of the PSM Act does not mean that the CSA has an interest in this matter beyond that of the many other public sector employees to whom Part 5 of the PSM Act applies. Such an interest is not sufficient to justify intervention.
44 For these reasons I am not persuaded that the CSA’s interest in this matter is sufficient to justify an order under s 27(1)(k) of the IR Act permitting intervention.
45 The CSA’s application for leave to intervene in application APPL 15 of 2022 will be dismissed.

Reasons for Decision

1         The Western Australian Prison Officers’ Union (WAPOU) and the Minister for Corrective Services (Minister) are in dispute about the correct interpretation of cl 48.2 of the Department of Justice Prison Officers’ Industrial Agreement 2020 (Prison Officers’ Agreement). WAPOU filed an application for an interpretation of cl 48.2 under s 46 of the Industrial Relations Act 1979 (WA) (IR Act).

2         WAPOU then informed the Commission and the Minister that it had become aware of the similarity between cl 48.2 of the Prison Officers’ Agreement and cl 19(5) of the Public Service Award 1992 (Public Service Award).

3         In circumstances where the Public Service Award applies to a large number of public sector employees, the Commission invited the Civil Service Association of Western Australia Incorporated (CSA) and the Minister for Industrial Relations to consider whether they wished to file an application to intervene in application APPL 15 of 2022.

4         The Minister for Industrial Relations did not wish to intervene.

5         The CSA seeks to intervene. It argues that it has sufficient interest to intervene because its industrial instruments cover approximately 39,723 government officers, the wording in cl 48.2 of the Prison Officers’ Agreement is almost identical to the wording in cl 19.5 of the Public Service Award, and there are a further nine public sector industrial instruments to which the CSA is a party that also contain clauses with similar wording. Finally, the CSA argues that application APPL 15 of 2022 arises out of a disciplinary matter dealt with under Part 5 of the Public Sector Management Act 1994 (WA) (PSM Act), which applies to its members who are public service officers, juvenile custodial officers and social trainers.

6         WAPOU argues that the CSA should be granted leave to intervene because ‘there is a serious question of fact and law’ about whether a decision in application APPL 15 of 2022 would affect the interpretation of the other industrial instruments the CSA has identified, and because there would be a risk of multiple proceedings ‘if this matter is not decided in the current application’.

7         The Minister objects to the CSA being granted leave to intervene for reasons including that the proper approach to the construction of industrial agreements is not the same as the proper approach to the construction of awards. The proper construction of the Prison Officers’ Agreement can have no impact upon the proper construction of the Public Service Award or any other instrument referred to in the CSA’s application to intervene. The Minister says that the CSA does not have sufficient interest in application APPL 15 of 2022 to warrant it being granted leave to intervene.

8         The parties agreed that the Commission should decide the CSA’s application to intervene on the papers.

What must I decide?

9         I must decide whether the CSA has sufficient interest in the matter to be granted leave to intervene in application APPL 15 of  2022, and if so, on what terms.

Legal principles

10      The Commission’s power to grant leave to intervene is set out in s 27(1)(k) of the IR Act:

27. Powers of Commission

Except as otherwise provided in this Act, the Commission may, in relation to any matter before it 

(k) permit the intervention, on such terms as it thinks fit, of any person who, in the opinion of the Commission has a sufficient interest in the matter; and

11      The Full Bench considered s 27(1)(k) of the IR Act most recently in Australian Workers' Union, West Australian Branch, Industrial Union of Workers & others v (Not Applicable) [2016] WAIRC 00966 (AWU v NA) from [17]-[21]:

[17] The principles for the Commission to consider when determining whether to exercise its discretion to allow a person to intervene in proceedings pursuant to its power to do so under s 27(1)(k) of the IR Act, in particular the determination whether a person has, in the opinion of the Commission, a sufficient interest in a matter that that person should be heard, were considered by Sharkey P in Gairns v The Royal Australian Nursing Federation Industrial Union of Workers, Perth (1989) 69 WAIG 2343.  In Gairns the substantive application was an application brought before the President's original jurisdiction under s 66 of the IR Act for an interpretation of union rules.  The federal nursing union, the Australian Nursing Federation, sought intervention in the proceedings.  So, too, did federal and state Academic Unions.  President Sharkey found that the most helpful dissertation of principles relating to intervention was set out in Re Ludeke; Ex parte Customs Officers' Association of Australia, Fourth Division [1985] HCA 31; (1985) 155 CLR 513; (1985) 13 IR 86.

[18] In Ludeke, the matter before the High Court was an application by the Customs Officers' Association of Australia, Fourth Division to make absolute an order nisi for a prerogative writ to quash an order made by Justice Ludeke that leave be granted to the Administrative and Clerical Officers' Association, Australian Government Employment (ACOA) to intervene in the matter subject to limitation on certain questions it raised in its submissions in a demarcation dispute between that union and the ACOA.  Chief Justice Gibbs at (519) - (520), with whom Dawson J agreed, observed:

The critical question is whether the prosecutor will be denied natural justice if it is allowed to intervene in ACOA's application only to the limited extent allowed by Ludeke J. It may be said immediately that it is clear that notwithstanding the wide discretion in matters of procedure given to the Commission by s. 40(1) of the Act, the Commission is bound to observe the rules of natural justice: Reg. v. Commonwealth Conciliation and Arbitration Commission; Ex parte Angliss Group ((1969) 122 C.L.R. 546, at p. 552); Reg. v. Moore; Ex parte Victoria ((1977) 140 C.L.R. 92, at pp. 101-102); Reg. v. Isaac; Ex parte State Electricity Commission (Vict.) ((1978) 140 C.L.R. 615, at p. 620). That means that a person whose rights will be directly affected by an order made by the Commission must be given a full and fair opportunity to be heard before the order is made. That requirement will not necessarily be satisfied if the Commission relies only on the fact that the person concerned has been heard on the same question by the same member of the Commission on a previous occasion. In general, the rules of natural justice are not satisfied unless the opportunity to be heard is afforded in the proceeding in question, although the fact that there had been an earlier hearing would be relevant in determining what constituted a full opportunity to be heard. However, natural justice does not require that everyone who may suffer some detriment as an indirect result of an order of the Commission is entitled to be heard before the order is made. Orders made by the Commission may affect many members of the community who are not parties to the proceedings in question but that does not mean that any member of the community who will be indirectly affected by an order of the Commission has a right to be heard in those proceedings. It has been held that a person who is not a party to a dispute, but who may nevertheless be affected, indirectly and consequentially, by an order made in settlement of the dispute is not entitled to be heard before the matter is determined: Reg. v. Moore; Ex parte Victoria; Reg. v. Isaac; Ex parte State Electricity Commission (Vict.).

[19] From these observations of Gibbs CJ in Ludeke, the following principles emerge:

(a) Every person whose rights will be directly affected by an order must be given a full and fair opportunity to be heard; and

(b) The principles of natural justice do not require that everyone who may suffer a detriment as an indirect result of an order or who is indirectly affected is entitled to be heard before the order is made.

[20] Justice Mason in Ludeke made similar observations.  He observed that an interest which in its nature is inadequate to support intervention in legal proceedings in a court may be sufficient to support intervention in a matter of industrial arbitration before the Commission (523).  His Honour found that if an organisation has a substantial interest sufficient to sustain an application to the court for prohibition then, generally speaking, it is desirable that the Commission should recognise that interest, subject to discretionary considerations, as a basis for intervention (525).  In making this observation, his Honour had regard to the decision in R v Holmes; Ex parte Public Service Association (NSW) [1977] HCA 70; (1977) 140 CLR 63 where it was found that where the prosecutor had relevant coverage under its eligibility rule there could be no doubt that it had a substantial interest sufficient to sustain its intervention and that a lack of coverage would result in the prosecutor's interest being much more tenuous (525).  Justice Mason in Ludeke also said (527):

Indeed, the principal object of intervention is to ensure that all interested parties will participate in a single resolution of a controversy instead of being relegated to a resolution of the controversy in several proceedings.  It is the attainment of this object that justifies intrusion into the litigant's right or interest in pursuing his proceedings as he chooses to constitute them.

[21] Justice Brennan said that he generally agreed with the judgment of the Chief Justice.  His Honour then went on to add that in determining whether a repository of a statutory power is bound to hear a person who is not directly involved in proceedings regard must be had (528):

to all the circumstances of the case, including the language of the statute, the nature of the power and of the body in which the power is reposed, the nature of the proceedings, the procedural rules that govern the proceedings (especially any provision for intervention by a person not directly involved in them), the interests which are likely to be affected, directly or indirectly, by the exercise of the power and the stage the proceedings have reached when the repository of the power learns of those interests. Generally speaking, a decision that will affect adversely a person's legal rights or his proprietary or financial interests or his reputation ought not to be taken without first giving him an opportunity to be heard provided such an opportunity can be reasonably given (F.A.I. Insurances Ltd. v. Winneke ((1982) 151 C.L.R. 342, at pp. 411-412)), even if that person is not directly involved in the proceedings which lead to the making of the decision: cf. Reg. v. Town and Country Planning Commissioner; Ex parte Scott ([1970] Tas. S.R. 154, at pp. 182-187; 24 L.G.R.A. 108, at pp. 137-141). But that is not an absolute rule.

CSA’s submissions

12      The CSA says its right to intervene comes from statute. The Commission does not have inherent jurisdiction to permit intervention so the Commission’s decision about the CSA’s application to intervene must be made in the statutory context. The CSA says that the Minister is applying the wrong test.

13      The CSA says that when deciding applications for leave to intervene, the Commission ‘has generally applied Re Ludeke; Ex Parte Customs Officers Association of Australia [1985] HCA 31 (Ludeke), which followed the reasoning in  Australian Railways Union v Victorian Railway Commissioners [1930] HCA 52.

14      In particular, the CSA draws the Commission’s attention to Mason J’s reasoning at 331 in Ludeke, where he says:

I think we would be wise to exercise it by allowing only those to be heard who wish to maintain some particular right, power or immunity in which they are concerned’, ‘an interest which in its nature is inadequate to support intervention in legal proceedings in a court may be sufficient to support intervention in a matter of industrial arbitration before the Commission’ and that ‘the principal object of intervention is to ensure that all interested parties will participate in a single resolution of a controversy instead of being relegated to a resolution of the controversy in several proceedings.

15      The CSA also relies on [19]-[21] of AWU v NA. It says that the interpretation of clauses with similar wording in industrial instruments that the CSA is a party to ‘is a “particular right, power or immunity” as required by [AWU v NA] because it is an industrial right that applies to our members’.

16      I understand the effect of the CSA’s submission to be that not only is the CSA a party to the Public Service Award, but it is also a party to at least nine other industrial instruments that have provisions with wording similar to cl 48.2 of the Prison Officers’ Agreement:

a) Government Officers Salaries, Allowances and Conditions Award 1989;

b) Juvenile Custodial Officers Award;

c) Government Officers (Social Trainers) Award 1988;

d) Education Department Ministerial Officers Salaries, Allowances and Conditions Award 1983;

e) Department of Communities (CSA) Family Resource Workers, Welfare Assistants and Parent Helpers Award 1990;

f) Government Officers (Insurance Commission of Western Australia) Award 1987;

g) Parliamentary Employees Award 1989;

h) WA Health CSA Dental Technicians (Dental Health Services) Award 2016; and

i) Dental Health Services – Dental Officers – CSA Industrial Agreement 2021.

17      In total, the CSA says that it is a party to industrial instruments that collectively cover 39,723 employees. The CSA argues ‘the particular higher duties clauses have evolved in the public sector through flow-on, and so any decision on their meaning will be persuasive for similar clauses.’

18      Further, the CSA says that application APPL 15 of 2022 arose out of a dispute about the effect of a demotion under Part 5 of the PSM Act. This section applies to public service officers, juvenile custodial officers and social trainers.

19      The interpretation declared in application APPL 15 of 2022 ‘may impact as to how the clauses in the CSA’s instruments are interpreted, especially where the industrial contexts are similar’. Despite ‘any small differences in language or industrial context’ the CSA’s interest is ‘substantial enough to warrant intervention’. It says ‘[t]he particular higher duties clauses have evolved in the public sector through flow-on, and so any decision on their meaning will be persuasive for similar clauses’.

20      The CSA says that the ‘interpretative exercise’ for industrial agreements and awards is not as different as the Minister says. In both cases, the Commission must begin with the plain meaning of the words. To not grant the CSA leave to intervene in this matter would be ‘contrary to the objective of preventing repetitive litigation on similar clauses and future interventions’. Whether the industrial context of the industrial instruments set out at above is similar to the industrial context of the Prison Officers’ Agreement is a question of fact and law ‘for which the CSA should be allowed to make submissions on as the CSA has established sufficient interest in the answer to that question’.

21      For these reasons, the CSA says it has sufficient interest in the matter and should be granted leave to intervene.

WAPOU’s submissions

22      WAPOU’s submissions are brief. It says that s 27(1)(k) of the IR Act ‘confers extensive discretion on the Commission to permit intervention, and there is nothing in the statute to support limiting the discretion by reference to considerations that may apply in legal proceedings in court’.

23      It says the primary question is whether the intervener has ‘sufficient interest’ and it is not an absolute rule that it must be a direct interest: Gairns v Royal Australian Nursing Federation Industrial Union of Workers (1989) 69 WAIG 2343 at 2347 per Sharkey P.

24      The nature of the proposed intervener’s interest need not reach the level required to permit intervention in court proceedings: AWU v NA at [20]. The principal object of allowing intervention is to resolve disputes in a single proceeding. An intervener may be establish a sound basis for intervention on this point alone: AWU v NA at [20].

25      The CSA is said to have identified ‘many industrial instruments which contain similar language to the provision the subject of these proceedings, which were made in a similar industrial context’. There is a question of fact and law about whether a decision on the current application ‘may influence the interpretation of instruments that the CSA has identified’ and there is a ‘significant risk of multiple proceedings’. The Commission should grant the CSA leave to intervene in this application.

Minister’s submissions

26      The Minister opposes the CSA’s application for leave to intervene. He says that the proper approach to the construction of industrial agreements is not the same as the proper approach to the construction of awards. Awards are subsidiary legislation made by the Commission or Public Service Arbitrator but agreements are made between negotiating parties and registered by the Commission or Public Service Arbitrator. The proper approach to construing industrial agreements fixes upon the proper approach to construing contracts, which is to determine the objective intention of the parties as understood from the text in the context in which it appears.  It is not relevant what the parties objectively intended in the awards referred to by the CSA.

27      The proper construction of industrial agreements turns upon the objective intention expressed in the text and the context in which it appears. The industrial context (public sector employment) is part of the context of the text, but each industrial instrument will also have its own more specific context, for example the specific employees covered by that industrial instrument. Importantly, ‘each instrument will have a different context as far as the balance of the text of the instrument is concerned’. The Prison Officers’ Agreement stands alone because it does not have the same textual context as any of the industrial instruments referred to by the CSA.

28      Parties to industrial instruments that are not the subject of application APPL 15 of 2022 can make other applications, including under s 46 of the IR Act, about the proper construction of those industrial instruments.

29      Further, the CSA has not provided a summary of what it proposes to say in intervention. It is possible that the CSA could submit that the Prison Officers’ Agreement should be construed differently to the industrial instruments that  it says has clauses with similar wording to cl 48.2. For example, this could be because of the effect of admissible evidence that the CSA might try to lead about the construction of those industrial instruments.

30      In those circumstances, the CSA should not be granted leave to intervene.

31      The Minister also submits that if the CSA is granted leave to intervene, it should be required to file an outline of the submissions it intends to make as an intervener in relation to application APPL 15 of 2022. Further, if the CSA is granted leave to intervene, then each and every employer party to the industrial instruments referred to by the CSA should properly be invited to intervene. There should also be an assessment of other instruments in the State industrial relations system to see whether there are any other industrial instruments with similar provisions. If there are, the parties to those instruments should also be invited to intervene.

Consideration

32      Having considered the application to intervene and the submissions from the CSA, WAPOU and the Minister, I am not persuaded that the CSA has sufficient interest in this matter.

33      Under section 27(1)(k) of the IR Act, the Commission may permit intervention if the Commission considers that the person has a sufficient interest in the matter.

34      Applying the reasoning in Ludeke, adopted by the Full Bench in AWU v NA, if the CSA’s rights or its members’ rights would be directly affected by the order/s sought in application APPL 15 of 2022 then clearly the CSA would have sufficient interest in this matter to justify granting leave to intervene.

35      The Prison Officers’ Agreement does not apply to the CSA or its members. Declaring the true interpretation of that agreement would not directly affect the rights of the CSA or its members.

36      That cl 19(5) of the Public Service Award may be ‘almost identical’ to cl 48(2) of the Prison Officers’ Agreement does not mean that the CSA has a sufficient interest in this matter. The proper approach to the construction of awards is not identical to that of industrial agreements.

37      The principles that apply to the interpretation of industrial agreements are the principles that apply to interpretation of contracts. The Full Bench said at [21]-[23] of Fedec v Minister for Corrective Services [2017] WAIRC 00828; (2017) 97 WAIG 1595:

[21] The approach that is to be applied when interpreting an industrial agreement is well established.  This is:

(a) Industrial agreements are usually not drafted with careful attention to form by persons who are experienced in drafting documents that have legal effect.

(b) The task of construction of an industrial agreement is to be approached in a way that allows for a generous construction:  City of Wanneroo v Holmes [1989] FCA 369; (1989) 30 IR 362.

(c) Industrial agreements are made for industries in light of the customs and working conditions of each industry and must not be interpreted in a vacuum divorced from industrial realities:  George A Bond & Co Ltd (in liq) v McKenzie [1929] AR (NSW) 498; City of Wanneroo v Holmes (378 - 379) (French J).

[22] The general principles that apply to the construction of contracts and other instruments also apply to the construction of an industrial agreement.  In Re Harrison; Ex parte Hames [2015] WASC 247, Beech J said [50] - [51]:

The general principles relevant to the proper construction of instruments are wellknown. In summary:

(1) the primary duty of the court in construing an instrument is to endeavour to discover the intention of the parties as embodied in the words they have used in the instrument;

(2) it is the objectively ascertained intention of the parties, as it is expressed in the instrument, that matters; not the parties' subjective intentions. The meaning of the terms of an instrument is to be determined by what a reasonable person would have understood the terms to mean;

(3) the objectively ascertained purpose and objective of the transaction that is the subject of a commercial instrument may be taken into account in construing that instrument. This may invite attention to the genesis of the transaction, its background and context;

(4) the apparent purpose or object of the relevant transaction can be inferred from the express and implied terms of the instrument, and from any admissible evidence of surrounding circumstances;

(5) an instrument should be construed so as to avoid it making commercial nonsense or giving rise to commercial inconvenience. However, it must be borne in mind that business common sense may be a topic on which minds may differ; and

(6) an instrument should be construed as a whole. A construction that makes the various parts of an instrument harmonious is preferable. If possible, each part of an instrument should be construed so as to have some operation (Electricity Generation Corporation v Woodside Energy Ltd [2014] HCA 7; (2014) 251 CLR 640 [35] (French CJ, Hayne, Crennan & Kiefel JJ); Kidd v The State of Western Australia [2014] WASC 99 [122]; Red Hill Iron Ltd v API Management Pty Ltd [2012] WASC 323 [106] - [112]; Primewest (Mandurah) Pty Ltd v Ryom Pty Ltd [2014] WASCA 28 [55] (Martin CJ, Pullin & Murphy JJA agreeing)).

These general principles apply in the construction of an industrial agreement (Director General, Department of Education v United Voice WA [2013] WASCA 287 [18] - [20] (Pullin J, Le Miere J agreeing), [83] (Buss J)). The industrial character and purpose of an industrial agreement is part of the context in which it is to be construed (Amcor Ltd v Construction, Forestry, Mining & Energy Union [2005] HCA 10; (2005) 222 CLR 241 [2] (Gleeson CJ and McHugh J); Director General v United Voice [81]; see also Amcor v CFMEU 66 (Kirby J), 129 - 130 (Callinan J)).

[23] To these principles, the following observations made by Pullin J in Director General, Department of Education v United Voice WA [2013] WASCA 287; (2013) 94 WAIG 1 [18] - [19] should be added:

The Agreement has to be construed to determine what the intention of the parties was at the time the Agreement was entered into. This has to be determined by ascertaining what a reasonable person would have understood the words of the Agreement to mean taking into account the text, the surrounding circumstances known to the parties and the purpose and object of the transaction: Toll (FGCT) Pty Ltd v Alphapharm Pty Ltd [2004] HCA 52; (2004) 219 CLR 165 [40]; Pacific Carriers Ltd v BNP Paribas [2004] HCA 35; (2004) 218 CLR 451 [22].

Surrounding circumstances may only be taken into account if the ordinary meaning of the words used by the parties is ambiguous or susceptible of more than one meaning: Codelfa Construction Pty Ltd v State Rail Authority of New South Wales [1982] HCA 24; (1982) 149 CLR 337, 352; McCourt v Cranston [2012] WASCA 60 [23].

38      I accept that there may be circumstances where a person has sufficient interest in a matter, even where their interest is indirect and would not support intervention in legal proceedings in a court. 

39      The CSA seems to argue that it should be granted leave to intervene so it can be heard at the substantive hearing about whether the interpretation of the Prison Officers’ Agreement could impact the awards mentioned by the CSA. That submission is misconceived. The issue of whether the interpretation of the Prison Officers’ Agreement could impact the awards and industrial agreement set out at [16] is said to be the basis for the CSA’s interest in this matter. The CSA has had an opportunity to be heard about that. The CSA chose to be heard on the basis of its written submissions.

40      In my view, that other awards and one industrial agreement to which the CSA is a party contain clauses with similar wording to cl 48.2 of the Prison Officers’ Agreement is too tenuous a connection to amount to a sufficient interest in this matter. The Commission’s task in interpreting the true meaning of a clause in an industrial agreement involves considering the objective intention of the parties from the text in the context in which it appears. Industrial agreements each have their own textual context. It therefore does not follow that an interpretation of cl 48.2 of the Prison Officers’ Agreement in this matter would affect the interpretation of a clause in a different industrial agreement or award, even if that clause is similarly worded.

41      Accordingly, I do not consider that the ‘industrial rights’ of the CSA’s members under other industrial instruments would suffer, even as an indirect result of an order, if the CSA is not permitted to intervene in this matter. The rights and interests that may be affected by an order in this matter are those of WAPOU, its members and the Minister. In any event, to the extent that the CSA and its members could be indirectly affected by an order made in this matter, such an interest is not substantial. It is not sufficient to entitle the CSA to be heard before the order is made.

42      Contrary to the submission of WAPOU and the CSA, allowing the CSA to intervene in this matter would not have the effect of avoiding multiple proceedings. This is because a resolution in this matter could not be said to settle other disputes about the interpretation of similarly worded clauses in other awards or industrial agreements. A dispute about the interpretation of a clause in an industrial agreement can only be resolved by considering the objective intention of the parties from the text in the context of that particular industrial agreement. Intervention in this matter would not lead to the single resolution of a controversy. It would not settle a dispute about the interpretation of a different industrial agreement or award.

43      As noted by Gibbs CJ in Ludeke at 520, ‘Orders made by the Commission may affect many members of the community who are not parties to the proceedings in question but that does not mean that any member of the community who will be indirectly affected by an order of the Commission has a right to be heard in those proceedings.’ That application APPL 15 of 2022 may have arisen out of a dispute in relation to a disciplinary matter dealt with under Part 5 of the PSM Act does not mean that the CSA has an interest in this matter beyond that of the many other public sector employees to whom Part 5 of the PSM Act applies. Such an interest is not sufficient to justify intervention.

44      For these reasons I am not persuaded that the CSA’s interest in this matter is sufficient to justify an order under s 27(1)(k) of the IR Act permitting intervention.

45      The CSA’s application for leave to intervene in application APPL 15 of 2022 will be dismissed.
