38 We reject the defendant's submission that it should not be ordered to pay the prosecutor's costs of the reference. While it might be said that both parties acted reasonably, in the sense that neither acted improperly or in any way which might be said to be an abuse of the court's process in taking the steps that they did (for example, in the case of the defendant in filing its notice of motion or in the case of the prosecutor in submitting that a reference of questions should be made to the Full Bench or, in the case of both parties, in agreeing to an adjournment of the Full Bench proceedings to await the outcome of the proceedings in the Rockdale Beef reference), it must be recognised that in raising the issues that it did in its notice of motion, the defendant was making a choice as to the approach it would take to the litigation.
39 Although one might understand why the legal advisers of the defendant felt obliged to give the advice they did based on the decision of Schmidt J, it must also be recognised that it was a matter for the defendant whether it acted on that advice and it must be reasonably taken to have accepted that if it acted on that advice then the consequences (including consequences in costs) of so acting would be consequences for which it would be liable.
40 As to the defendant's reliance on the judgment of McHugh J in Lai Qin, it is pertinent to note that his Honour held (at 624):
In most jurisdictions today, the power to order costs is a discretionary power. Ordinarily, the power is exercised after a hearing on the merits and as a general rule the successful party is entitled to his or her costs ( Latoudis v Casey (1990) 170 CLR 534). Success in the action or on particular issues is the fact that usually controls the exercise of the discretion. A successful party is prima facie entitled to a costs order ( Latoudis at 543, 566-568). When there has been no hearing on the merits, however, a court is necessarily deprived of the factor that usually determines whether or how it will make a costs order.
41 His Honour's subsequent observations, which are relied on by the defendant, that where both parties acted reasonably no costs order should be made, must be seen in their proper context; for example, at pp 624 to 625, his Honour gave these examples:
In an appropriate case, a court will make an order for costs even when there has been no hearing on the merits and the moving party no longer wishes to proceed with the action. The court cannot try a hypothetical action between the parties ( Australian Securities Commission v Aust-Home Investments Ltd (1993) 44 FCR 194 at 201). To do so would burden the parties with the costs of a litigated action which by settlement or extra-curial action they had avoided. In some cases, however, the court may be able to conclude that one of the parties has acted so unreasonably that the other party should obtain the costs of the action ( Australian Securities Commission v Aust-Home Investments Ltd (1993) 44 FCR 194 at 201). In administrative law matters, for example, it may appear that the defendant has acted unreasonably in exercising or refusing to exercise a power and that the plaintiff had no reasonable alternative but to commence a litigation.
42 His Honour, later at p 625 however, distinguished that situation from those where the court may feel confident that, although both parties have acted reasonably, one party was almost certain to have been successful if the matter was heard. This is such a case.
43 We also consider that some of the observations made by the Full Bench in Lucon at 464 (at [24]) are apposite here. Here, as in Lucon, the reference was appropriate but it is going too far to say that there were public interest considerations in the defendant raising the points it did by its notice of motion. The points raised were essentially to assist, or to vindicate, the defendant's forensic situation in the litigation and, as we have already observed, ultimately the defendant had a choice as to whether it would maintain the points that it raised. We reject the criticism which the defendant appears to be making as to the prosecutor's conduct in seeking the reference of the issues raised by the notice of motion as questions of law to the Full Bench pursuant to s 5AE. That step was the direct and likely consequence of the defendant's notice of motion and it was clearly open to WorkCover to act on the basis that the defendant in filing its notice of motion, and therefore raising similar points to that dealt with in Rockdale Beef, was making a choice in raising the issue and was therefore prepared to accept the consequences of the choice it made.
44 In conclusion, we order that the defendant pay the prosecutor's costs of, and in connection with, the reference to the Full Bench.
