Ulan Coal Mines Pty Ltd v Association of Professional Engineers, Scientists and Managers, Australia

Ulan Coal Mines Pty Ltd v Association of Professional Engineers, Scientists and Managers, Australia [2025] FCAFC 127 is a Full Court decision about the Fair Work Act's single interest employer authorisation regime. APESMA had obtained an authorisation from the Fair Work Commission requiring three underground coal mine operators to bargain together with a cohort of employees and the union, despite the employers' opposition.

The employers challenged that outcome in the Federal Court. They argued that the Commission had misunderstood or mishandled several statutory criteria in section 249, including common interests, public interest, reasonable comparability and majority employee support. The Full Court dismissed all three applications. The central practical point for employers is that court review in this area is about legal error, not a second chance to rerun the merits.

The dispute started with APESMA applying for a single interest employer authorisation under section 249 of the Fair Work Act 2009 (Cth). The employers relevant to the court proceedings were Ulan Coal Mines Pty Ltd, Peabody Energy Australia Coal Pty Ltd and Whitehaven Coal Mining Ltd. The judgment says they operated underground black coal mines: Ulan No 3 Underground Coal Mine, Wambo Underground Coal Mine and Narrabri Coal Mine.

APESMA also sought to include Great Southern Energy Pty Ltd trading as Delta Coal, which operated Chain Valley Colliery. But the Commission did not include Delta Coal in the authorisation because it found key differences between Delta Coal and the other three employers. That detail matters because it shows the Commission was not simply treating all coal operations as interchangeable. It drew a line and excluded one proposed employer.

The authorisation had a real commercial and industrial effect. The Court described it as requiring the three employers, against their will, to bargain with a small cohort of their respective employees and APESMA to enter into an enterprise agreement. The Court also observed that these provisions marked a significant departure from the historical model of enterprise bargaining, which had generally been based on voluntary bargaining at the enterprise level.

After the Commission made the authorisation on 23 August 2024, each of the three employers brought judicial review proceedings in the Federal Court. They sought orders quashing the Commission's decision and the authorisation. Ulan and Peabody also sought further relief in the nature of mandamus or declarations. The three proceedings were heard together by the Full Court.

The Full Court made clear that this was a judicial review case. That framing is critical. The Court said it was not deciding the merits of the underlying industrial dispute, and not deciding broader social policy about whether different employers should be forced to bargain together against their will. Instead, the Court had to decide whether the Commission's decision was vitiated by jurisdictional error.

The extract identifies the main complaints. One was that the Commission had misunderstood the analysis of whether there were "common interests" between the employers under section 249(3), and had looked at that issue at too high a level rather than with the necessary granularity. Another was that the Commission had failed to afford Peabody procedural fairness, or had failed to consider a centrally relevant submission about a commercial conflict of interest between two of the employers when deciding whether any presumption of common interests had been rebutted.

The employers also argued that the Commission had taken too narrow a view of the public interest requirement, had misconstrued the criterion of reasonable comparability by focusing at a very general level and not dealing with the actual differences raised in evidence and submissions, and had erred in its findings about majority support. On majority support, the extract shows an argument that the Commission should have considered whether the employee vote showing employees wanted to bargain was genuine or informed, or that the decision was otherwise legally unreasonable.

In practical terms, the employers were not merely saying the Commission had reached the wrong industrial conclusion. They were saying the Commission had asked itself the wrong legal questions, failed to engage with matters it had to address, or otherwise exceeded the limits of its authority. That is the kind of argument a court can entertain on judicial review.

The judgment spends substantial time setting out the statutory framework in Part 2-4 of the Fair Work Act. That context helps explain both the employers' concern and the Court's approach. The Court noted that the newer regime can force multiple employers to engage in bargaining at a multi-enterprise level, which sits uneasily with the historical emphasis on voluntary enterprise-level bargaining.

Section 249 sets out when the Fair Work Commission must make a single interest employer authorisation. The extract shows that, where the application is made by a bargaining representative rather than by the employers themselves, the Commission must be satisfied of several matters. These include that at least some employees who will be covered are represented by an employee organisation, that the employers and bargaining representatives have had the opportunity to express their views, and that each employer either consented or falls within subsection (1B).

Subsection (1B), as reproduced in the extract, includes requirements such as the employer having employed at least 20 employees at the relevant time, the employer not already being caught by certain other authorisation situations, a majority of relevant employees wanting to bargain, and the absence of certain current agreement or bargaining circumstances described in subsection (1D).

Because these employers were not franchisees under the same franchise, the common interest pathway in section 249(3) was central. Under that pathway, the Commission must be satisfied that the employers have clearly identifiable common interests and that it is not contrary to the public interest to make the authorisation. The extract also reproduces section 249(3A), which says that matters that may be relevant to common interests include geographical location, regulatory regime, and the nature of the enterprises and terms and conditions of employment.

The extract further shows that reasonable comparability was a separate requirement under section 249(1)(b)(vi). It also highlights statutory presumptions that may apply where an employer employed 50 employees or more at the time of the application. Those presumptions relate to reasonable comparability and to the requirements in section 249(3), unless the contrary is proved.

For employers, this framework matters because it shows the kinds of evidence likely to matter before the Commission. The statutory questions are not abstract. They invite evidence about workforce size, current agreement status, employee support, operational features, business activities, regulatory environment and the practical similarities and differences between the named employers.

The result was straightforward. The Full Court ordered that all three applications be dismissed. The orders were made on 5 September 2025.

The Court's reasons, as reflected in the extract, show that it approached the matter strictly as judicial review. It asked whether the Commission had correctly construed section 249 and lawfully performed the statutory task. The Court was not persuaded that the employers had shown jurisdictional error in the Commission's treatment of the criteria they challenged.

That means the authorisation remained in place. The employers' attempt to have the Commission's decision quashed failed. The extract supports a careful public summary of the outcome: the Court rejected the employers' legal challenge and left the single interest employer authorisation standing. What should not be overstated is the precise reasoning on each individual ground, because the available text does not reproduce every part of the Court's detailed analysis.

The most useful lesson from this case is not limited to mining. It is about process, evidence and the limits of court review. If your business may be named in a single interest employer authorisation application, the Commission hearing is likely to be the main battleground. By the time a matter reaches the Federal Court, the question is usually no longer whether the Commission made the best evaluative judgment. The question is whether it made a legal error serious enough to invalidate the decision.

That has practical consequences. If you say your business should not be grouped with others, you need to identify exactly why. General assertions that your operations are different may not be enough. You should be ready to explain your business activities, workforce structure, site conditions, regulatory setting, bargaining history and any features that make comparison with the other employers misleading or unfair.

The extract also shows that majority support can be contested, and that current agreement status matters. So employers should not treat employee support evidence or agreement coverage as side issues. They are part of the statutory architecture.

Another practical point is that the regime can apply without employer consent. The Court expressly recognised that the authorisation in this case required the employers, against their will, to bargain with a small cohort of employees and APESMA. Businesses should therefore plan for the possibility that a union-led application may move quickly and may require a prompt, evidence-based response.

Although every case turns on its own facts, the statutory questions identified in the judgment point to the kinds of material employers should gather early. If you are responding to a proposed authorisation, think in terms of proving how your business actually operates rather than relying on broad submissions.

Useful material may include workforce data showing how many employees you employed at the relevant time, details of which employees would be covered by the proposed agreement, copies of current enterprise agreements and their nominal expiry dates, records of any written agreement to bargain for a proposed single-enterprise agreement, and evidence about the way employee support was measured.

You may also need material about the nature of your operations and business activities, your regulatory environment, geographical setting, terms and conditions of employment, and any operational or commercial features said to distinguish your business from the others named in the application. If you say there is a conflict of interest or another feature that makes grouping inappropriate, that argument should be supported by clear evidence and framed carefully against the statutory criteria.

This page is based on the Federal Court's published judgment and orders for Ulan Coal Mines Pty Ltd v Association of Professional Engineers, Scientists and Managers, Australia [2025] FCAFC 127. The extract identifies the review decision, the parties, the hearing dates, the orders, the statutory provisions in issue and the broad grounds argued by the employers.

The extract is detailed enough to explain the commercial story, the legal issue and the result with confidence. However, because it does not reproduce every part of the Court's full reasoning, this page avoids over-claiming about the Court's treatment of each individual ground beyond what the extract clearly supports.
