CONSIDERATION
8 I am certainly not persuaded that this is an appropriate case for an award of indemnity costs. The case was, by no means, as straightforward as the United Workers Union suggests. Although it is not necessary to demonstrate exceptional circumstances, many of the authorities emphasise the caution with which the discretion (in assessing unreasonableness) under s 570 of the FW Act should be exercised, having regard to the legislative purpose as an 'access to justice' provision.
9 A difficulty for the United Workers Union is that One Tree's application included a claim for declaratory relief in relation to the meaning and effect of the EA. Consistent with the United Workers Union's submission, that part of the case was referred off to the Commission. It cannot at this point be determined that such part of the case was unreasonable.
10 More importantly, and in relation to the constitutional argument, the pursuit of an arguable point of law is sufficient to take the proceeding out of the concept of unreasonableness referred to in s 570 of the FW Act, as noted in Kanan (at 264-265) and Leighton Contractors (at [7(3)]). While I had initial as well as ultimate misgivings about the constitutional argument, it would be difficult to conclude that it was not reasonably arguable. It had been the subject of no relevant authority in any court and was, at least arguably capable of drawing on well-established principles of high authority on private arbitration. Moreover, and despite misgivings, I found that the argument as a point of law was sufficiently arguable to justify the grant of an interlocutory injunction. It would be a mistake to approach the arguability point on the basis that the Court, with the benefit of hindsight thought the point was 'easily resolved once it [was] exposed to scrutiny' such that its pursuit was unreasonable: Fair Work Ombudsman v Hu (No 2) [2019] FCAFC 175 (at [7]).
11 Within this conclusion, it must follow that knowledge of the identified facts by One Tree does not render the argument unreasonable. One Tree's case was that those facts were immaterial in that they did not evidence or constitute an 'arbitration agreement' between One Tree and the United Workers Union or its employees. The conclusion I reached was that those facts gave rise to a notion of statutorily mandated consent: see One Tree (No 2) (at [90]).
12 Having close regard to the statutory purpose of s 570, I am not persuaded that any of the limbs of s 570(2) of the FW Act are satisfied and, on that basis, there is no capacity to award costs.
