For business readers, one of the most useful parts of the available judgment is the Commission's summary of the evidence it considered most significant. Those features show the kinds of facts that can influence whether an arrangement is characterised as service provision or labour supply.
First, the framework agreements and site work packages described what the OS entities were to provide as services, but the expected number of full-time equivalent employees required by BMA was central, and the price paid was overwhelmingly determined by the cost of employing those workers. That points toward labour supply rather than payment for a separate output.
Second, the OS entities had some involvement in planning and gave feedback, but the mine and maintenance plans were determined by BMA. Those plans set the timing, priority and nature of the work. That suggested the host remained in control of the operational agenda.
Third, OS supervisors had an important day-to-day role, but workers still had to perform work in accordance with detailed and highly prescriptive BMA requirements, including SOPs, SWIs and other policies and procedures. They were also subject to monitoring, intervention and direction through BMA systems including Minestar and Modular.
Fourth, the workers used plant, equipment and systems provided by BMA, and those were the same plant, equipment and systems used by BMA's own production and maintenance employees in operating the mines.
Fifth, while the work could be described as specialist or expert in a general sense, it was the same kind of specialised work performed by BHP Coal employees at the same mines. The Commission treated that as suggesting that, in substance, what was being provided was labour.
Finally, the Commission considered that many matters relied on by BHP and the OS entities to show service provision were also applicable to labour supplied at the mines by other labour hire providers. In the Commission's evaluative assessment, those similarities weighed in favour of labour supply rather than a distinct service.
