Is there a sufficiently arguable case for final relief
13 The background circumstances revealing the underlying legal contest about approval of the enterprise agreement were discussed in the Full Court decision of 12 February 2015, referred to earlier. The principal contest concerned the eligibility of a group of 21 employees of the applicant to vote whether to accept the terms of the enterprise agreement. In her more recent decision, Deputy President Asbury again took the view, for reasons which were explained in detail, that all those employees who might have voted to approve the enterprise agreement were entitled to do so. She held that they had not ceased to be production workers who "will be covered" by the terms of the enterprise agreement.
14 The latest Full Bench, on the other hand, by majority held that cl 1.3 of the enterprise agreement required that those to be covered by the enterprise agreement were those whose particular work was covered by the classifications contained in the enterprise agreement, a condition which Deputy President Asbury did not regard as necessary or determinative.
15 One issue then, upon which the decision of the Full Bench turned, was an issue about the construction of the enterprise agreement, and its coverage. Those questions of coverage also raise questions about the operation and application of s 53 of the FW Act, as informed by s 256A of the FW Act.
16 Those issues may readily be seen as legal issues, at least in part. The applicant will argue that the Full Bench made errors of law. That will not necessarily be sufficient. To obtain final relief in the present proceedings the applicant will need to show that the Full Bench made a jurisdictional error.
17 The respondent argued that there was no arguable case of jurisdictional error to support the present application for a stay, relying upon the following passage in the judgment of Hayne J in Re Refugee Review Tribunal; Ex parte Aala (2000) 204 CLR 82 (at [163]):
163 In deciding whether writs of prohibition and certiorari (and analogous forms of relief) should be granted, a distinction is drawn between jurisdictional error and error within jurisdiction. This Court has not accepted that this distinction should be discarded. As was noted in Craig v South Australia, that distinction may be difficult to draw. The difficulty of drawing a bright line between jurisdictional error and error in the exercise of jurisdiction should not be permitted, however, to obscure the difference that is illustrated by considering clear cases of each species of error. There is a jurisdictional error if the decision maker makes a decision outside the limits of the functions and powers conferred on him or her, or does something which he or she lacks power to do. By contrast, incorrectly deciding something which the decision maker is authorised to decide is an error within jurisdiction. (This is sometimes described as authority to go wrong, that is, to decide matters within jurisdiction incorrectly.) The former kind of error concerns departures from limits upon the exercise of power. The latter does not.

18 The applicant, on the other hand, referred to Craig v South Australia (1995) 184 CLR 163 where the High Court said (at 179):
If … an administrative tribunal falls into an error of law which causes it to identify a wrong issue, to ask itself a wrong question, to ignore relevant material, to rely on irrelevant material or, at least in some circumstances, to make an erroneous finding or to reach a mistaken conclusion, and the tribunal's exercise or purported exercise of power is thereby affected, it exceeds its authority or powers. Such an error of law is jurisdictional error which will invalidate any order or decision of the tribunal which reflects it.
19 The applicant wishes to argue that the Full Bench made a jurisdictional error because it exercised its power to quash the approval based on an error of law and it thereby exceeded or misunderstood its authority or powers or the basis upon which they might be exercised. I think such a case is sufficiently arguable, so far as it concerns the order made on 18 September 2014.
20 Ultimately, the task for the FWC, including the Full Bench, was whether approval of the enterprise agreement was mandated by s 186 of the FW Act. If the Full Bench misunderstood the legal principles which it was to apply to decide that question, or misconstrued or misapplied the statutory provisions, it is arguable that the Full Bench made a jurisdictional error when it quashed the approval.
21 I accept, therefore, that there is a sufficiently arguable case for relief at the final hearing of the application that the order made on 18 September 2014 was invalid and ineffective to quash the approval of the enterprise agreement.
22 The challenge to the Full Bench decision and order of 19 December 2014 probably only arises, it seems to me, if the applicant fails in its challenge to the order made on 18 September 2014. The consequence of that failure would be that it must be taken that the decision to quash, based on the construction favoured by the majority of the Full Bench, was not invalid. The legal (and jurisdictional) error then asserted will be that the Full Bench wrongly failed to accept an undertaking from the applicant proffered under s 190 of the FW Act.
23 Two undertakings were offered, ranked as a preferred undertaking and an alternative undertaking. The preferred undertaking suggested a drafting modification to cl 1.3 of the 2013 enterprise agreement. The alternative undertaking proposed to confine the duties of the 21 disputed employees to work under the enterprise agreement for a period of at least three months.
24 The Full Bench took the view that neither suggested undertaking could overcome the invalidity in the approval process which it had identified. The Full Bench went on to say, however, that it would not in any event have accepted either of the undertakings in the exercise of its discretion.
25 The proposition inherent in the contention that the Full Bench was able to accept the proffered undertaking depends, I think, first upon acceptance of the argument that an invalid vote may be validated by altering the permitted voting constituency after the event, by amending coverage of an agreement retrospectively.
26 Then the argument depends upon the contention that the Full Bench was obliged to accept one or other of the undertakings.
27 It is unnecessary to express a view about the ultimate strength of those contentions. At their highest the argument which depends on them seems to me to have less force than the other challenge. For reasons which I give later, I would not, in any event, grant a stay of the order made on 19 December 2014. There would be no useful purpose served in doing so.
