Should the Discretion be Exercised?
57 The crucial question so far as the amended application is made pursuant to the ADJR Act is whether it is appropriate in the circumstances of this particular case for the Court to exercise the discretion vested in it by s10(2)(b)(ii) of that Act. So far as the amended application is made in reliance on s 39B(1A)(c) of the Judiciary Act, I take the view that the appropriate course is similarly for the Court to give consideration to whether it is appropriate in the circumstances of this case for the discretionary relief sought by the applicant to be refused because the respondent's decision can be reviewed by the Tribunal.
58 It was not suggested by counsel for the applicant that the respondent's notice of motion was too narrowly drawn to allow the determination of the present motion of the issue of whether the claims made by paragraph (ii) of the applicant's claims for relief should be dismissed on discretionary grounds. I have received detailed submissions from the parties on this issue.
59 In Dranichnikov Gummow and Callinan JJ, with whom Hayne J agreed, at [33] observed that an 'often compelling discretionary bar' to a claim for prerogative relief is the availability of other relief. The availability of other relief might be thought, all else being equal, to be a stronger discretionary bar before the High Court than before the Federal Court; control of the workload of the nation's highest court of appeal is a matter of considerable public importance. Nonetheless, even before the Federal Court the availability of another proper and adequate forum for relief is a factor that the authorities indicate is to be given considerable weight (see [71] and [72] below).
60 The applicant placed reliance on certain High Court authorities in which statements have been made to the effect that a writ of prohibition will issue 'almost as a right' where want or excess of jurisdiction has been established (see, Aala per Gaudron and Gummow JJ, with whom in this regard Gleeson CJ agreed, at [50]-[51] and Kirby J at [148]; The Queen v Ross-Jones; Ex parte Green (1984) 156 CLR 185; The Queen v Australian Stevedoring Industry Board; Ex parte Melbourne Stevedoring Company Proprietary Limited (1953) 88 CLR 100). It is important, in my view, to note the context in which such statements have been made. Only when the context is understood can any apparent inconsistency between the authorities be resolved.
61 In Aala an application had been made to the High Court in its original jurisdiction for writs of mandamus, prohibition and certiorari and for declarations. The applicant had exhausted all other avenues of relief; his appeal to the Full Federal Court from a decision of a judge of the Court refusing an application for judicial review had been dismissed and he had not sought special leave to appeal to the High Court. In concluding that a writ of prohibition should issue 'almost as a right' the High Court was addressing a situation in which a denial of relief would have had the effect that a decision made in want or excess of jurisdiction would remain in force.
62 In The Queen v Ross-Jones; Ex parte Green the High Court issued a writ of prohibition in respect of an order made by a judge of the Family Court notwithstanding that an appeal lay against the making of the order to the Full Court of the Family Court. The order made by the judge of the Family Court restrained a litigant before the Supreme Court of Victoria from taking any steps to enforce a judgment of the Supreme Court of Victoria. The dispute before the High Court concerned the extent, if any, of the jurisdiction of the Family Court, whether in its original or its appellate jurisdiction, to make an order of the kind made by the judge of the Family Court. In the present case the power of the respondent, and thus of the AAT on review of the decision of the respondent, to suspend the applicant's registration as a migration agent is not in dispute. What is in issue is the lawfulness of the procedure adopted by the respondent when it purported to exercise that power. Any unlawfulness of this character is capable of being avoided by the Tribunal.
63 The Queen v Australian Stevedoring Industry Board; Ex parte Melbourne Stevedoring Company Proprietary Limited is a case in which a writ of prohibition issued to the respondents prohibiting them from cancelling or suspending the registration of the prosecutor as an employer under the Stevedoring Industry Act 1949 (Cth). It was not contended in that case that a convenient alternative remedy was available to the prosecutor. Indeed, the relevant legislation included a privative clause of apparently wide application which purported to protect orders or directions of the Board from challenge.
64 Properly understood, the above authorities do not, in my view, detract from the observation made by Gummow and Callinan JJ in Dranichnikov.
65 I note that this is not a case in which the legislation regulating the specific subject matter (in this case the Migration Act which regulates migration agents) discloses a clear intention as to the court or body that should review decisions of the Authority. The circumstances of the instant case is thus distinguishable from those considered by, for example, Moore J in Darling Downs Bacon Co-operative Association Ltd v Comptroller‑General of Customs (1994) 50 FCR 435. In that case his Honour concluded that the processes provided by the Customs Act 1901 (Cth) for review of a decision of the Comptroller‑General of Customs meant that ordinarily the discretion under s 10(2)(b)(ii) of the ADJR Act should be exercised in relation to an application to the Court under that Act in respect of a decision of the Comptroller‑General of Customs. See also Swan Portland Cement Ltd v Comptroller‑General of Customs (1989) 25 FCR 523 at 530 (FC).
66 I proceed in this case on the basis that the relevant legislation does not disclose an intention that decisions of the respondent should, all else being equal, be reviewed by the Tribunal in preference to the Court. The issue to be determined, in my view, is whether, in the circumstances of this particular case, the Tribunal is a more appropriate forum than the Court.
67 In this case, assuming the decision of the Authority to be tainted by error, the Tribunal has the capacity to reach a decision concerning the applicant's registration as a migration agent which is untainted by error. Of course, if the Tribunal should repeat any legal error made by the Authority, or should its decision be affected by other legal error, an appeal will lie to this Court under s 44 of the AAT Act. However, a decision of the Tribunal may attract no criticism either on the merits or with respect to questions of law.
68 On the other hand, should this Court, on review of the decision of the Authority, set aside the decision of the Authority and refer the matter to which the decision relates to the Authority for further consideration, any decision thereafter made by the Authority would remain open to review by the Tribunal, and indeed, subject to s 10(2)(b)(ii) of the ADJR Act, by the Court. It is not suggested that any relief sought before the Court would have the legal or the practical effect of making it impossible for the applicant's registration as a migration agent to be suspended or cancelled in reliance on the material apparently in the possession of the respondent.
69 In the circumstances, considerations of expedition and efficiency would seem to favour the prosecution by the applicant of her application to the Tribunal. To use the language employed by Latham CJ, Rich, Dixon, McTiernan and Webb JJ in R v Commonwealth Court of Conciliation and Arbitration; Ex parte Ozone Theatres (Aust) Ltd (1949) 78 CLR 389 in a passage at 400 on which the applicant relied, it would seem that 'a more convenient and satisfactory remedy' exists before the Tribunal.
70 It seems to me that the authorities provide support for this approach. In Edelsten at 424 Northrop J observed:
'Dr Edelsten did argue that there were special features applicable which should be taken into account to deny that conclusion [i.e. that the Court should exercise its discretion under s 10(b)(2)(ii) of the ADJR Act]. For instance, the serious nature of the consequences of a determination by the Review Committee, the effect on the medical practitioner concerned, the fact that the Review Committee is not able to consider questions of law, such as whether there was a denial of natural justice in the earlier proceeding before the Minister or the Committee of Inquiry, and the limited nature of the review. But it is difficult to see how that can have any real meaning when the Review Tribunal is in essence and in fact exercising the powers of the Minister on material that was properly before the Minister.'
