The Authorities
39 The question of construction arising in this case does not appear to have been directly addressed in the authorities. It has been assumed in at least two decisions that the Minister, in exercising the power conferred by s 200, or its predecessor, is not limited to taking into account deportable offences identified in s 201, or its equivalent in earlier legislation. Another judgment, that of the Full Court in Gunner, appears to have taken a different view.
40 The issue in Haoucher v Minister for Immigration, Local Government and Ethnic Affairs (1993) 42 FCR 287, was whether the Minister, in considering a recommendation by the AAT to revoke a deportation order made pursuant to s 12 of the Migration Act, was entitled to take into account convictions for offences committed after the AAT had made its recommendation. (At this time the AAT's powers on review of a deportation decision were limited to affirming the decision or remitting the matter for reconsideration in accordance with its recommendations: see Minister for Immigration and Ethnic Affairs v Pochi (1981) 149 CLR 139.) Section 12 of the Migration Act was then in the following terms:
"Where-
(a) a person who is a non-citizen has, either before or after the commencement of this section, been convicted in Australia of an offence;
(b) at the time of the commission of the offence the person -
(i) was not an Australian citizen; and
(ii) had been present in Australia as a permanent resident for a period of less than 10 years…; and
(c) the offence is an offence for which the person was sentenced to death or to imprisonment for life or for a period of not less than one year,
the Minister may order the deportation of the person."
41 It would seem clear enough that, although no specific finding was made, the appellant had been present in Australia as a permanent resident at least since January 1979 (at 288). A number of offences taken into account by the Minister were committed between 1990 and 1992.
42 The Full Court rejected the appellant's contention that the Minister could not take into account offences committed after the AAT had made its recommendation. Their Honours said this (at 296, 298):
"There is nothing in the Migration Act which requires the Minister to limit his reconsideration to events such as they existed at the time of the Tribunal's recommendation. Any such limitation would be not only inconvenient and artificial but would be inconsistent with the subject matter, scope and purpose of the Act. The Minister is charged with the very heavy responsibility under the Act to act in the interests of the Australian community and there is nothing to suggest that in the exercise of a very important function under the Act the Minister is obliged to act on material that may be inadequate, stale or erroneous.
…
In this case a crucial question for consideration at all time was the risk that the appellant would be a recidivist. This was critical to the decision of the AAT and to the original decision of the Minister. It was also critical to the ultimate decision of the Minister.
When the Minister came to make his final decision he was in a position to assess the risk that the appellant would offend again by looking at what had happened in fact. As Latham CJ observed in Willis v Commonwealth (1946) 73 CLR 105 at 109:
'…where actual facts are known, speculation as to the probability of those facts occurring is surely an unnecessary second-best'."
While these observations were not directed to the issue of construction arising in the present case, they provide some support for the view we have expressed as to the unconfined nature of the discretion conferred by s 200 of the Migration Act.
43 A second relevant case is Minister for Immigration and Multicultural Affairs v Ali [2001] FCA 1385. By way of background to that decision, it is necessary to point out that the authorities establish that, where a conviction is the foundation for the exercise of the power to deport now contained in s 200 of the Migration Act, no challenge can be made in deportation proceedings to the fact of the conviction or to the essential facts on which it is based: Minister v Daniele; Degerli v Minister for Immigration and Ethnic Affairs (1981) 4 ALN N39; Minister for Immigration and Affairs v Gungor (1982) 42 ALR 209; Minister v SRT. Thus in Minister v SRT, the Full Court said (at 244):
"[W]here the decision to be reached depends upon there having been a sentence that satisfies s 201(c) of the Act, it is not open to the Tribunal to engage in any inquiry which would impugn the sentence. Accordingly, at least the essential facts found by a sentencing judge in the course of his or her deliberations concerning sentence and upon which the sentence is based must be accepted by the Tribunal. The most obvious example of such a fact is a finding as to the circumstances of the commission of the offence."
44 None of these authorities involved convictions that were offences within s 201 of the Migration Act. In Minister v Ali, however, the AAT had given consideration to a number of convictions for offences committed by a non-citizen against whom the Minister had made a deportation order. One conviction was for assault occasioning actual bodily harm, for which the non-citizen was sentenced to nine months imprisonment. That conviction could not of itself have been the foundation for the exercise of the deportation power, since the term of imprisonment was less than twelve months: s 201(c).
45 The Minister applied for judicial review on the ground that the AAT had impermissibly gone behind two of the convictions and examined whether the non-citizen had been correctly convicted and sentenced. One was the assault conviction. It is not clear what sentence was imposed in respect of the other conviction, for theft of a motor vehicle. In any event, Branson J (at [22]) identified the relevant question as whether
"the Tribunal may go behind the outcome of a criminal proceeding to which the person the subject of the deportation order was a party where the criminal proceeding was not that which resulted in the conviction and sentence that enlivened the power to make the deportation order." (Emphasis added.)
Her Honour held (at [43]) that the Migration Act should be construed as requiring a decision-maker under s 200 to treat a conviction and sentence (not being the sentence upon which the power to deport is based) as strong prima facie evidence of the facts upon which they were necessarily based.
46 Minister v Ali was clearly argued on the assumption that the AAT was entitled, if not bound, to consider the non-citizen's convictions for offences not within s 201 of the Migration Act. Her Honour therefore did not specifically address the construction issue. But the judgment shows how, on the construction we prefer, the principles limiting the AAT's power to go behind convictions might be interpreted to accommodate convictions for offences that fall outside s 201 of the Migration Act, either because they were committed outside the ten year period or because they attracted sentences of less than twelve months imprisonment.
47 In contrast to these two cases, the Full Court in Minister v Gunner (which was not cited by either party) made observations which appear to support the appellant's position in the present case. In Gunner, the question was whether the Minister had power to make orders for the cancellation of a non-citizen's visa under s 501 and to grant a certificate under s 502 of the Migration Act (which provides for the Minister to declare the non-citizen an excluded person, thereby excluding judicial review of the decision), in circumstances where the AAT had previously set aside an order made by the Minister's delegate under s 200 for the non-citizen's deportation. The Full Court held that the Minister's powers under ss 501 and 502 of the Migration Act were unaffected by the AAT's previous decision. The Court made these additional comments (at 408):
"In any event, it is not entirely correct to say that the Minister's decision was 'based on' the same facts and circumstances as had been considered by the AAT. The Minister did not have before him any material which was not before the AAT. But because of the different provisions of ss 201 and 501 the test is not the same and the criteria are different. The Minister, in exercising the discretion conferred by s 501, was entitled to take into account matters which were not relevant to a decision under s 200 based on the criteria specified in s 201.
The banking conspiracy offence, by far the most serious, was not viewed as a deportable offence because it was ongoing before the respondent became a permanent resident. Further, the passport conspiracy offence did not fall within s 201 because it resulted in a sentence of less than 12 months. On the other hand, both of those matters were factors which were relevant to the determination by the Minister of whether or not he should be satisfied that the respondent was not of good character. The Minister, in acting under s 501, is to have regard to any past criminal conduct and the person's general conduct. The words 'good character' should be understood as a reference to the enduring moral qualities of a person. Conduct may make those qualities visible, but it should not be confused with them. In each case, having had regard to the conduct, the Minister must still come to a further conclusion, namely, whether or not to be satisfied that the person is not of good character: see Minister for Immigration and Ethnic Affairs v Baker (1997) 73 FCR 187 at 197."
48 This passage seems to imply two propositions:
· first, the AAT, in considering whether to affirm or revoke the deportation order, made in respect of Mr Gunner, had not taken into account the banking conspiracy or passport offences committed by him, because neither was within s 201 of the Migration Act; and
· secondly, the AAT had correctly regarded these convictions as irrelevant to the exercise of its discretion pursuant to s 200 of the Migration Act, because it was entitled to consider for this purpose only offences within s 201.
49 Although the reasoning of the AAT (reported as Re Gunner v Minister for Immigration and Multicultural Affairs (1997) 50 ALD 330) is not entirely clear on the point, it is, with respect, doubtful whether in fact the AAT excluded the banking conspiracy and passport offences from its consideration. The AAT specifically referred, for example, to the banking conspiracy offences on two occasions in the course of considering whether the deportation order should be affirmed or revoked (at pars 47 and 50). These references suggest that the AAT regarded the banking offences, at least, as relevant to that issue notwithstanding that they would not, of themselves, have enlivened the power in s 200.
50 The second point implicit in the Full Court's reasoning is more directly relevant to the present case. If the Full Court's apparent view of the relationship between ss 200 and 201 of the Migration Act constitutes an essential part of its reasoning, its approach should be followed by this Court, particularly having regard to the approval of the decision and reasoning by the High Court in Minister v Jia. This is so notwithstanding that the Full Court did not have occasion to explain why it considered that the criteria set out in s 201 limit the matters that are relevant to a decision under s 200 of the Migration Act.
51 In our view, however, the reference in Gunner to the interrelationship between ss 200 and 201 of the Migration Act was not an essential step in the Full Court's reasoning. The passage we have quoted begins with the words "in any event". The Full Court had previously held (at 407-408) that ss 501 and 502 provide "separate sources of power" (from ss 200 and 201) and that the fact that the powers might be exercised in relation to the same "collocation of facts" as had previously been considered by the AAT in exercising its discretionary power under s 200 could not affect the meaning of ss 501 and 502. In the passage we have quoted from Gunner, the critical point being made by the Full Court was that the criteria governing the exercise of the power to deport under s 200 are not the same as those governing the cancellation of a visa on character grounds under s 501. The Court's suggestion that the banking conspiracy and passport offences were excluded from the scope of the discretionary power under s 200 was merely an illustration of this point. The proposition that the scope and nature of the discretion conferred by s 200 are not identical to that conferred by s 501, stands independently of the particular illustrations provided by the Full Court. In our view, the illustrations given by the Full Court to exemplify the differing scope of the discretionary powers conferred by s 200, on the one hand, and ss 501 and 502, on the other, did not constitute an essential step in its reasoning. The comments on the relationship between ss 200 and 201 are, therefore, to be regarded as obiter dicta.
52 Of course, if the High Court in Minister v Jia intended to approve all aspects of the reasoning in Minister v Gunner, that would very considerably strengthen the argument that the view apparently held by the Full Court as to the limited scope of the discretionary power conferred by s 200 of the Migration Act should be followed. But we do not understand the High Court's approval in Minister v Jia of the reasoning in Gunner to extend to this particular issue. Gleeson CJ and Gummow J expressed (at 441) approval of the reasoning in Gunner in the context of rejecting an argument that ss 501 and 502 should be qualified by an unexpressed limitation to the effect that the powers conferred by those sections cannot be exercised where the AAT has previously set aside a deportation order, unless there has been a material change of circumstances. The passage from Gunner quoted by their Honours (not the same one as we have cited) supported their Honours' rejection of this argument, because in that passage the Full Court pointed out that the Minister had not disobeyed the AAT's ruling, but had rather exercised a separate statutory power available to him. We do not read their Honours' judgment (nor that of Kirby J) as endorsing the comments in Gunner to the effect that s 201 should be read as limiting the scope of the discretion conferred by s 200.
53 In our respectful opinion, the dicta in Gunner, to the extent that they were intended to convey a view about the relationship between ss 200 and 201 of the Migration Act, should not be followed. Perhaps not surprisingly, given the issues in Gunner itself, the Full Court did not explain why it implicitly endorsed a construction which constrains the scope of the discretion conferred by s 200 of the Migration Act by reference to the class of offences identified in s 201. For the reasons we have given, we prefer a construction that permits the Minister and the AAT, in cases where the power conferred by s 200 of the Migration Act is enlivened, to take account of offences committed by a non-citizen, even though they would not, of themselves, render the non-citizen liable to a deportation order.
