Sydney Trains v Australian Rail, Tram and Bus Industry Union (Separate Question)

Sydney Trains v Australian Rail, Tram and Bus Industry Union (Separate Question) [2024] FCA 1479 is a Federal Court decision about enterprise bargaining and protected industrial action under the Fair Work Act 2009 (Cth).

The case did not arise from a franchise relationship. It arose from bargaining between Sydney Trains, NSW Trains and several unions for a replacement enterprise agreement. The immediate issue was whether industrial action that had already been balloted and notified lost its protected status after the Fair Work Commission later made a single interest employer authorisation.

Wheelahan J answered that question against the employers. The Court held that the statutory phrase "proposed enterprise agreement" is used at a generic level and is not fixed to an immutable agreement type from the outset. On that reasoning, the later authorisation did not change the character of the proposed enterprise agreement in the way the employers argued, and the declaration they sought was refused.

The Rail Agencies were already covered by the Sydney Trains and NSW TrainLink Enterprise Agreement 2022. That agreement had been approved in February 2023 and commenced operation on 17 February 2023. It reached its nominal expiry date on 1 May 2024, but it continued in operation because it had not been replaced or terminated.

As the expiry date approached and passed, bargaining began for a replacement agreement. The unions served a log of claims on 15 April 2024. On 31 May 2024, the Rail Agencies issued notices of employee representational rights. From June 2024, the parties held bargaining meetings, with about 30 meetings having occurred by the time the matter came before Wheelahan J.

The bargaining was not straightforward. A key dispute was whether Sydney Trains and NSW Trains were "related employers" under the Fair Work Act. That mattered because the Act draws a distinction between a single-enterprise agreement and a multi-enterprise agreement. The unions had requested bargaining for a single interest employer agreement. The Rail Agencies rejected that request and maintained that they were related employers entitled to bargain for a single-enterprise agreement.

Despite that disagreement, the bargaining process moved into the industrial action stage. Between 18 July 2024 and 2 September 2024, the unions applied for protected action ballot orders. Between 1 August 2024 and 4 September 2024, the Commission made those orders. Employees were then balloted and the proposed forms of industrial action were authorised. From 5 September 2024, the unions gave notices of intended industrial action.

Then the legal setting changed. On 27 September 2024, the RTBU applied to the Commission for a single interest employer authorisation. On 6 December 2024, the Commission granted that authorisation. The judgment records that the Rail Agencies consented to the application and that other union bargaining representatives supported it.

That authorisation had an important practical effect. By force of s 172(5), the Rail Agencies could no longer bargain for any enterprise agreement other than a single interest employer agreement. Because a single interest employer agreement is a type of multi-enterprise agreement, the employers argued that the bargaining framework had shifted in a way that undermined the earlier protected action ballots and notices.

On 8 December 2024, the Rail Agencies urgently went to the Federal Court and obtained interlocutory relief from Perram J restraining the unions from continuing industrial action. The matter was then docketed to Wheelahan J, who ordered a separate trial on a final basis of the declaration claim.

The separate question was narrow but commercially important. The Court had to decide whether, because of the single interest employer authorisation made on 6 December 2024, the earlier protected action ballot orders and notices of proposed industrial action were no longer effective to bring the foreshadowed industrial action within the scope of protected industrial action.

In practical terms, the employers said this: the ballots and notices had occurred while bargaining was being conducted on the basis of a proposed single-enterprise agreement, but after the authorisation the only agreement that could be bargained for was a single interest employer agreement, which is a type of multi-enterprise agreement. On that footing, they argued that the industrial action was no longer "authorised by a protected action ballot" within the meaning of the Act.

The Court therefore had to interpret how the Fair Work Act uses the phrase "proposed enterprise agreement". Was that phrase tied to a fixed and specific agreement type from the beginning of bargaining, or was it a broader statutory expression capable of covering a bargaining process even if the legal character of the agreement pathway later changed?

The judgment also worked through the statutory setting. It explained that the Act recognises different agreement types, that a single interest employer agreement is a subset of multi-enterprise agreements, and that a single interest employer authorisation can be made in relation to a proposed enterprise agreement covering two or more employers. The Court also noted that the Act's concept of "notification time" can apply in more than one way during the course of bargaining, which supported a less rigid reading of the statutory scheme.

Wheelahan J refused the declaration sought by the Rail Agencies. The Court held that the statutory expression "proposed enterprise agreement" is a generic expression and is not pitched at a level of specificity that includes a fixed or immutable type of enterprise agreement.

That conclusion was central. Because the phrase was used generically, the making of the single interest employer authorisation on 6 December 2024 did not affect the character of the proposed enterprise agreement in the way the employers contended. The later authorisation changed what kind of agreement could then be bargained for, but it did not automatically mean that the earlier protected action ballots and notices ceased to support protected industrial action.

The Court therefore held that the Rail Agencies had not established that the notified industrial action was not, and would not be, protected industrial action. Judgment was entered for the respondents on the declaration claim. The Court also discharged paragraph 1 of the interlocutory orders made on 8 December 2024 and listed the proceeding for case management on 31 January 2025.

The decision is a good example of a court resisting an overly rigid reading of bargaining procedure. The employers' argument depended on treating the bargaining process as if it had to remain locked to one agreement type from start to finish. The Court instead read the Act as using broader language that could accommodate a change in bargaining pathway without automatically invalidating earlier procedural steps.

For readers who do not work with industrial relations terminology every day, the judgment is easier to follow if these concepts are separated.

A single-enterprise agreement is one category of enterprise agreement under the Fair Work Act. A multi-enterprise agreement is another. The Act also recognises sub-types within multi-enterprise agreements, including a single interest employer agreement, a cooperative workplace agreement and a supported bargaining agreement.

In this case, the disagreement was about which path applied to the Rail Agencies. The unions had argued for a single interest employer agreement. The Rail Agencies maintained that they were related employers and could bargain for a single-enterprise agreement. That disagreement mattered because the Act sets different rules for when two or more employers may make a single-enterprise agreement and when they may make a multi-enterprise agreement.

A single interest employer authorisation is an authorisation the Commission can make in relation to a proposed enterprise agreement that will cover two or more employers. Once such an authorisation is in operation, s 172(5) has a practical locking effect. The employer may only make a single interest employer agreement with the specified employees and must not initiate, agree to, or be required to bargain for another kind of enterprise agreement with those employees.

The employers' argument in this case was built on that locking effect. They said that once the authorisation was made, the earlier ballots and notices no longer matched the agreement now capable of being made. The Court rejected that argument because the Act's reference to a "proposed enterprise agreement" was not read as a narrow label fixed forever at the first stage of bargaining.

The judgment also discussed franchise provisions in the Act because they appear in the statutory scheme for related employers and single interest employer authorisations. But that discussion formed part of the legal analysis of the Act. It did not turn the case into a factual franchise dispute.

Most businesses will never face a dispute on the scale of the Sydney rail network, but the procedural lesson is broader than the facts. If your business is bargaining under the Fair Work Act, especially across more than one employing entity, the legal structure of bargaining matters from the start. So do the documents used to begin bargaining, the way the proposed agreement is described, the ballot applications, the ballot orders, and the notices of industrial action.

This case shows that a later change in bargaining structure may not automatically wipe out earlier steps. That matters for employers who might otherwise assume that a technical shift in agreement type will stop industrial action. The Court's answer was no, not necessarily. The statutory language and the actual bargaining history still have to be examined.

For business owners, there are two practical points. First, identify early whether you are dealing with one employer, multiple related employers, or a structure that may fall within common interest or franchise provisions. Secondly, if bargaining changes course part way through, do not assume that every earlier procedural step becomes invalid. Review the whole sequence before making operational decisions or seeking urgent court relief.

The case also shows the risk of fragmented decision-making. The Rail Agencies had issued notices of employee representational rights, participated in bargaining, dealt with ballot applications, and later consented to the single interest employer authorisation. Once those steps had occurred, the Court was not prepared to accept that the later authorisation alone destroyed the protected character of the industrial action that had already been balloted and notified.

The judgment is a reminder that industrial disputes often turn on documents and timing. Several steps were important here.

First, the unions served a log of claims. That helped frame the bargaining claims being advanced. Secondly, the Rail Agencies issued notices of employee representational rights on 31 May 2024. The judgment discusses those notices because they described the proposed enterprise agreement as a proposed single-enterprise agreement.

Thirdly, the unions applied for protected action ballot orders and obtained them. Those orders mattered because industrial action supporting employees' claims in bargaining must be authorised by a protected action ballot if it is to be protected industrial action. Fourthly, the employees were balloted and the proposed forms of industrial action were authorised. Fifthly, notices of intended industrial action were given from 5 September 2024.

Finally, the Commission granted the single interest employer authorisation on 6 December 2024. That was the event the employers relied on to say the earlier ballots and notices no longer did the legal work required by the Act. The Court rejected that submission, but only after closely examining how the Act uses the phrase "proposed enterprise agreement" and how the bargaining process had unfolded.

For businesses, the practical point is simple. Keep a clear chronology and copies of every bargaining document. In a fast-moving dispute, the answer may depend less on broad industrial strategy and more on the exact sequence of notices, applications, orders and authorisations.

The judgment was delivered on 19 December 2024 by Wheelahan J in the Federal Court of Australia. It determined a separate question on a final basis. The Court entered judgment for the respondents on the declaration claim, discharged part of the earlier interlocutory orders made on 8 December 2024, and listed the proceeding for case management on 31 January 2025.

That means the decision resolved the specific declaration issue argued on the separate question, but it did not necessarily end the broader proceeding. Readers should therefore understand the case as authority on the point decided, namely the effect of the later single interest employer authorisation on the earlier ballots and notices in this bargaining context.
