1 In our opinion, the usual costs order should be made. The appellant's costs of the appeal should be paid by the respondent.
2 The appellant, Mr Quinn, clearly identified in his outline of submissions the error of law on the basis of which the Court ultimately quashed the Tribunal's decision, namely, the Tribunal's failure to deal with the undertaking which he had proffered and, in particular, to explain why the undertaking had not been accepted. The Institute resisted the appeal, arguing that there was no error of law. The Institute had an interest in upholding the decision of the Tribunal and it argued strongly to that end. The Institute's role was that of protagonist. It was not in any sense appearing as amicus curiae.[1]
3 It was submitted that the Institute was simply assisting the Court by being a contradictor, and was thus acting in the public interest. We reject this submission. The Institute actively opposed the appeal and failed.
4 It was open to the Institute to take the view that the Tribunal did err in failing to address the question of the undertaking. This was certainly a matter to which the Institute should have turned its mind, in the light of what the Court said in granting a stay of the suspension pending the appeal.[2] Had the Institute formed that view, it could have consented to an order setting aside the Tribunal's decision on penalty and substituting the undertaking.
5 In its written submission, the Institute argues that it would have been "entirely inappropriate" for a professional body like the Institute to consent to an appeal being allowed in that way. We disagree. The Director of Public Prosecutions, who likewise discharges important public functions, takes precisely that course in a criminal appeal when he considers that there has been error below.
6 Where a tribunal's decision is appealed on a question of law, the respondent to the appeal must assess, in the usual way, whether error of law is likely to be made out. If the respondent decides to contest the appeal and seek to uphold the tribunal's decision, it runs the usual costs risk if the appeal succeeds.
7 The Institute's position in this respect is no different from that of any other regulatory agency which is a party to proceedings before a domestic tribunal. The Transport Accident Commission, the Victorian WorkCover Authority and the Environment Protection Authority Victoria regularly appear as respondents to review proceedings in the Victorian Civil and Administrative Tribunal in respect of decisions made in the exercise of their statutory powers. Decisions of that Tribunal are appellable on a question of law.[3] If the decision-making agency seeks unsuccessfully to defend such an appeal, it will be ordered to pay the appellant's costs.[4]
