the dietrich principle
17 The principle for which Dietrich stands was stated concisely in that case by Mason CJ and McHugh J (at 297-298):
"In our opinion, and in the opinion of the majority of this Court, the common law of Australia does not recognise the right of an accused to be provided with counsel at public expense. However, the courts possess undoubted power to stay criminal proceedings which will result in an unfair trial, the right to a fair trial being a central pillar of our criminal justice system. The power to grant a stay necessarily extends to a case in which representation of the accused by counsel is essential to a fair trial, as it is in most cases in which an accused is charged with a serious offence.
The applicant is entitled to succeed because his trial miscarried by virtue of the trial judge's failure to stay or adjourn the trial until arrangements were made for counsel to appear at public expense for the applicant at the trial with the consequence that, in all the circumstances of this case, he was deprived of his right to a fair trial and of a real chance of acquittal."
The other members of the majority agreed that, while a court cannot insist on the appointment of counsel to represent an accused, it can stay proceedings as an incident of the general power of court to ensure a fair trial of serious criminal offences: Dietrich, at 330-331, 335, per Deane J; 357-358, 361, per Toohey J; at 374-375, per Gaudron J.
18 There are formidable difficulties in applying the Dietrich principle to the hearing by the AAT of an application to review a deportation decision. The reasoning in Dietrich was based on two propositions. The first is that an accused person has a right to receive a fair trial according to law; the second is that the courts have the power to stay criminal proceedings which will result in an unfair trial. A criminal trial, of course, involves an adjudication of the guilt of the accused and, if guilt is established, the imposition of punishment. An administrative review of a deportation decision, even one based on criminal convictions, involves different considerations.
19 The power to exclude or expel non-citizens is an incident of sovereignty over territory: Chu Kheng Lim v Minister for Immigration, Local Government and Ethnic Affairs (1992) 176 CLR 1, at 29, per Brennan, Deane and Dawson JJ. As was said in Attorney-General (Canada) v Cain and Gilhula [1906] AC 542, at 546:
"One of the rights possessed by the supreme power in every State is the right to refuse to permit an alien to enter that State, to annex what conditions it pleases to the permission to enter it, and to expel or deport from the State, at pleasure, even a friendly alien, especially if it considers his presence in the State opposed to its peace, order, and good government, or to its social or material interests."
(This passage was quoted with approval in Lim, at 30; see also Robtelmes v Brenan (1906) 4 CLR 395, at 400-401, per Griffith CJ; at 411-412, per Barton J.)
20 It has long been accepted that deportation of a non-citizen is not to be regarded as punishment for a criminal offence. In O'Keefe v Calwell (1949) 77 CLR 261, Latham CJ said this (at 278):
"It was also argued that the order for deportation amounted to the imposition of a penalty without any judicial proceeding. Deportation is not necessarily punishment for an offence. The Government of a country may prevent aliens entering, or may deport aliens: Mulgrave v Chun Teeong Toy [1891] AC 272. Exclusion in such a case is not a punishment for any offence. Neither is deportation: see Attorney-General for Canada v Cain and Gilhula [1906] AC 542, at 547: 'The power of expulsion is in truth but the complement of the power of exclusion.' The deportation of an unwanted immigrant (who could have been excluded altogether without any infringement of right) is an act of the same character: it is a measure of protection of the community from undesired infiltration and is not punishment for any offence. This view of the nature of deportation was adopted by this Court in Ex parte Walsh and Johnson; In re Yates (1925) 37 CLR 36."
More recently, in Minister for Immigration and Ethnic Affairs v Pochi (1980) 31 ALR 666, Deane J (with whom Evatt J agreed) summarised the course of authority in the following terms (at 685):
"If the slate were clean, I should have thought that there was a great deal to be said for the view that the banishment, consequent upon his conviction of a criminal offence, of one who has become an accepted member of the Australian community was an interference with personal liberty by way of punishment. (See eg the dissenting judgment of Field J in Fong Yue Ting v United States (1892) 149 US 689 at 748-9). If that view were correct, a question would arise as to whether a provision purporting to confer upon an executive officer of the Commonwealth a power as close to the heart of judicial power as the subjection of the individual to interference with personal liberty by way of punishment was consistent with the provisions of Chapter III of the Constitution. It has however been said, in many cases, that deportation cannot properly be regarded as punishment of an offence (see, for example, Koon Wing Lau v Calwell (1949) 80 CLR 533 at 555; Ex parte Walsh and Johnson; In re Yates (1925) 37 CLR 36 at 61; O'Keefe v Calwell (1949) 77 CLR 261 at 278.) The validity of legislation entrusting to executive officers and organs, decisions as to the deportation of established residents has long been accepted (see, for example, Walsh and Johnson, supra, at 68-69, 96; Koon Wing Lau v Calwell, supra, at 555)."
Thus, even though a particular deportation decision may involve some overlap with sentencing considerations (for example the emphasis by the AAT in the present case on deterrence of non-citizens contemplating criminal conduct), a deportation decision is not regarded in Australia as having the same characteristics as a conviction for a criminal offence.
21 It is also well established that the power of Parliament, conferred by s 51(xix) of the Constitution, to make laws with respect to aliens authorises laws providing for the deportation of aliens by the Executive. Parliament also has power to authorise the Executive to restrain a non-citizen in custody to the extent necessary to make the deportation effective: Lim, at 30-31. The authority to detain a non-citizen in custody pending deportation is "neither punitive in nature nor part of the judicial power of the Commonwealth": Lim, at 32. Similarly, the power of deportation pursuant to statutory authority is executive in character: ibid. By contrast, the function of determining guilt and imposing punishment is exclusively judicial in character. It is for this reason that determinations of guilt in prosecutions for offences against laws of the Commonwealth cannot be made by the Executive: Lim, at 27.
22 The limited scope of the principle in Dietrich was recognised by the High Court in New South Wales v Canellis (1994) 181 CLR 309. In that case, the issue was whether a stay should be granted of an inquiry under s 475 of the Crimes Act 1900 (NSW) because of doubts concerning the guilt of a convicted person. The question arose because the State had refused to pay the costs of legal representation for certain witnesses required to appear before the inquiry.
23 The joint judgment of Mason CJ, Dawson, Toohey and McHugh JJ observed (at 328) that the principle established by Dietrich
"is that a court has jurisdiction to grant an adjournment or order a permanent stay of proceedings at a trial until such time as an indigent person charged with a serious criminal offence is provided with legal representation necessary for a fair trial or resources for such representation. As the majority judgments made clear, that principle is based on, and derives from, the accused's right to a fair trial." (Emphasis added.)
Their Honours continued (at 328):
"There is no suggestion in the majority judgments that a court could exercise a similar jurisdiction in civil proceedings or in committal proceedings; nor do they suggest that such a jurisdiction could be exercised in favour of an indigent person charged with a criminal offence which is other than serious. Furthermore, and this is of decisive importance in the present case, the principle in Dietrich is concerned with the right to a fair trial of a party to criminal proceedings; the principle has nothing at all to say about the protection of the interests of a witness, let alone the protection of the interests of a witness at an inquiry. Finally, Dietrich enunciated a principle governing the exercise of inherent jurisdiction by a court with respect to proceedings in that court; Dietrich did not consider the power of a tribunal with respect to the adjournment or stay of proceedings for the purpose of securing legal representation for a witness." (Emphasis added.)
24 As these passages show, there is nothing in the reasoning in Dietrich to suggest that the decision applies otherwise than to a court hearing a prosecution for a serious criminal offence under Commonwealth, State or Territory law. In particular, there is nothing to suggest that the reasoning applies to administrative hearings, including a hearing by the AAT in the course of reviewing a deportation order made by the Minister's delegate. On the contrary, the rationale underlying Dietrich, namely the power of a court to stay proceedings in order to prevent an unfair criminal trial taking place, does not apply to an administrative review conducted by a tribunal no matter how serious the consequences for the individual concerned.
25 There are other difficulties confronting the appellant. In a criminal trial, it is the prosecuting authority which initiates and conducts the criminal proceedings against the accused. A stay of proceedings until adequate legal representation is provided is doubtless an effective means of preventing the unfairness inherent in a trial for a serious criminal offence where an indigent accused is forced to represent himself or herself. In the present case, however, it was the appellant who sought review by the AAT of the decision to deport him. A stay of the AAT proceedings, of itself, would have achieved very little from the appellant's point of view, since the deportation order would have remained in force and he would have remained in detention pending deportation: Migration Act, s 253; see also Migration Act, ss 501-502; Minister for Immigration and Multicultural Affairs v Gunner (1998) 84 FCR 400. The appellant's submissions did not address these difficulties.
26 We should add that the appellant did not apply to the Attorney-General for assistance under s 69 of the AAT Act in connection with the proceedings determined by the AAT. Nor did the appellant make any request to the AAT to stay the operation or implementation of the deportation decision under s 41(2) of the AAT Act. Indeed, the issue of legal representation was not raised before the AAT. The failure to raise these issues may create other difficulties for the appellant. In any event, it is unnecessary to comment on the scope of the powers conferred by those provisions.
27 In our view, the principle established by Dietrich did not require the AAT to ensure that the appellant was provided with legal representation before deciding to affirm the delegate's decision that he should be deported.
