Consideration
52 The starting point is s 411 as that provision identifies the decisions which are reviewable.
53 Section 411 relevantly provides:
411 Definition of Part 7-reviewable decision
(1) Subject to subsection (2), the following decisions are Part 7-reviewable decisions:
…
(c) a decision to refuse to grant a protection visa, other than a decision that was made relying on:
(i) subsection 5H(2), or 36(1B) or (1C); or
(iii) paragraph 36(2C)(a) or (b);
(d) a decision to cancel a protection visa, other than a decision that was made because of:
(i) subsection 5H(2) or 36(1C); or
(ii) an assessment by the Australian Security Intelligence Organisation that the holder of the visa is directly or indirectly a risk to security (within the meaning of section 4 of the Australian Security Intelligence Organisation Act 1979); or
(iii) paragraph 36(2C)(a) or (b).
(2) The following decisions are not Part 7-reviewable decisions:
(aa) any decision to cancel a protection visa that is made personally by the Minister;
(a) decisions made in relation to a non-citizen who is not physically present in the migration zone when the decision is made;
(b) decisions in relation to which the Minister has issued a conclusive certificate under subsection (3);
(c) fast track decisions.
…
54 By s 414, which we have set out at [2] above, and leaving aside a decision where the Minister has issued a conclusive certificate under s 411(3), if a valid application is made under s 412 for review of a Part 7-reviewable decision, the Tribunal must review the decision. (Our emphasis.)
55 It is now common ground that the Tribunal may review a decision which was in fact made, even though invalid, that is, a decision that was purportedly made. As the plurality said in Plaintiff M174/2016 at [39]:
The fundamental reason for adopting that construction was fulfilment of the evident legislative purpose of the conferral of jurisdiction on the Tribunal "to promote good government by those carrying out the actual practical task of administering Acts of Parliament and making decisions incidental to that task": "[i]f administrative decisions are to be subjected to review in the course of good government exclusion from review of decisions made without power would remove from review those decisions most in need of review" and "technicality would be introduced at the outset".
56 Here the person who purported to make the decision did so without power because, unknown to her, she was not a delegate of the Minister.
57 The issue is no longer whether the Tribunal had "jurisdiction" to review the decision since the primary judge applied Brian Lawlor and found that the Tribunal did have that jurisdiction, contrary to the then submissions of the present respondents. The decision was a reviewable decision even though only a purported decision. As we have said, the respondents no longer challenge that conclusion. The present issue is a narrower one which is the powers available to the Tribunal for the purposes of its review of a Part 7-reviewable decision.
58 It is not apparent to us why Parliament would have intended that, for the purposes of the Tribunal's jurisdiction to review, jurisdiction should extend to an invalid decision but, for the purpose of the Tribunal's powers on review of such an invalid decision, those powers should be limited in respect of one species of invalidity, absence of authority.
59 The primary judge accepted that the invalid decision, despite an absence of delegation to the individual who made the decision, was a Part 7-reviewable decision, but rejected the submission that for the purposes of the review of that purported decision the Tribunal could exercise the powers and discretions conferred (or assumed to have been conferred) by the Migration Act on the purported decision-maker. This was because that person had no powers and discretions because of the absence of delegation. So, on that reasoning, the Tribunal had jurisdiction to entertain the application but did not have the relevant statutory powers and discretions that would have been available to the purported decision-maker had she been properly authorised.
60 It is difficult to discern a purpose for the construction adopted by the primary judge. The result does not sit well with the approach in Brian Lawlor. We accept that Brian Lawlor concerned the issue of whether or not a purported decision could be the subject of review by the Tribunal, rather than the present question of the powers and discretions of the Tribunal once it had been accepted that it did have the power to review the purported decision, but the decision of the primary judge seems to us to accept the larger premise but reject the smaller.
61 As a matter of principle, it seems unlikely that Parliament would have intended the reintroduction, at the level of the Tribunal's powers rather than its jurisdiction, of different classes of invalidity. Such a construction would have the effect, to adapt what was said in Plaintiff M174/2016 at [39] and reproduced at [55] above, that "technicality would be [re]introduced at the outset", which as there explained would frustrate the evident legislative purpose of conferring review jurisdiction on the Tribunal.
62 It is also not clear what, on the reasoning of the primary judge, is the source of the power in the Tribunal to set aside the decision: see Declaration 3 made by the primary judge on 16 November 2018. That is not a power "conferred by this Act on the person who made the decision" within s 415(1), but would appear to be found in s 415(2)(d). However that same subsection also confers power on the Tribunal to affirm or vary the decision.
63 By s 414(1), the Tribunal must review the decision which includes, as is the case here, a purported decision. There can be no legislative purpose in then not giving the Tribunal the power to do anything in consequence of its review. The Tribunal's procedural powers in conducting the review are considerable: see, eg, ss 427 and 428. It cannot have been intended by Parliament that after all that the Tribunal would have no decision-making or remedial powers on the review if it transpires, as it has in this case, that there was an irregularity in the instrument of delegation to the primary decision-maker.
64 We see no reason to construe "the person who made the decision" to mean only the identified individual who made the decision so as to limit the Tribunal's powers and discretions to those which the purported decision-maker had in law. We do not accept the respondents' submission that the powers conferred on the Tribunal by s 415(1) are parasitic on the powers of the actual decision-maker, that is, on the identity of the actual decision-maker.
65 In our opinion, in the present case the words in s 415(1) refer to the person who made the purported decision, or who purportedly made the decision, and to the powers and discretions that person would have had if the instrument of delegation had been legally effective.
66 If necessary to go further to deal with the proposition that this construction would permit the Tribunal to exercise powers and discretions where a "decision" was made by a busybody, we would note the following. First, this issue only arises once the Tribunal has jurisdiction in relation to the purported decision which, in the present case, would require the purported decision to meet the definition of a Part 7-reviewable decision and for a valid application for review to be made. Second, as in Brian Lawlor at FLR 343-344, ALR 315 per Bowen CJ, "in the ordinary course, it would be reasonably clear from the objective facts under which enactment or in the exercise of which statutory powers an official had purported to act." Third, the issue arises in the context of "carrying out the actual practical task of administering Acts of Parliament and making decisions incidental to that task": see Plaintiff M174/2016 at [39]. Here, the decision-maker who made the purported decision was a person holding or occupying a particular office or position who was engaged in such tasks. In another case, where the decision-maker did not hold such a position or engage in such tasks, the issue would arise whether the decision purportedly made bore a sufficient relationship to the Migration Act to engage the relevant jurisdictional provisions.
67 The apparent consequence of the primary judge's reasoning is that the Tribunal had jurisdiction in respect of the decision but no power to do anything under s 415(1) or s 415(2). Such a construction cannot have been intended. This odd consequence - to have jurisdiction (as accepted by the primary judge) but no power - is avoided by construing s 415(1) as referring to the person who made the decision and the powers and discretions that person would have had if the purported decision had been legally effective.
68 Our construction is consistent with the legislative history of s 415(1). It appears that the language presently under consideration was first added to the Migration Act by the Migration Reform Act 1992 (Cth). That Act inserted into the Migration Act s 115D(1), which stated that "[t]he review officer may, for the purposes of the review of an internally-reviewable decision, exercise all the powers and discretions that are conferred by this Act on the person who made the decision." Similarly, ss 119(1) and 166BC(1) were added to the effect that the then Immigration Review Tribunal and Refugee Review Tribunal "may, for the purposes of the review of an [IRT or RRT]-reviewable decision, exercise all the powers and discretions that are conferred by this Act on the person who made the decision."
69 The explanatory memorandum for the Migration Reform Bill 1992, circulated by the authority of the relevant Minister, said, at [282], [298] and [357] that each of ss 115D(1), 119(1) and 166BC(1) enabled the review officer or the IRT or the RRT, respectively, "to provide determinative merits review."
70 The Migration Reform Act also enacted ss 150K and 166HJ, which altered the operation of s 43 of the AAT Act so that it applied in relation to an IRT-reviewable decision or an RRT-reviewable decision, respectively, as if subsection (1) were omitted and the following subsections were substituted:
(1) The Tribunal may, for the purposes of the review of an [IRT or RRT]-reviewable decision, exercise all the powers and discretions that are conferred by the Migration Act 1958 on the person who made the decision.
This was said, at [322] and [405] of the explanatory memorandum, to have the effect that the Administrative Appeals Tribunal had the same powers as the IRT or the RRT had before the referral.
71 So far, we have approached the question as one of principle. The Minister submitted that there were only two relevant cases involving delegation. The respondents appeared to accept this although did not agree that the two cases relied on by the Minister, which we next consider, were relevant or supported the Minister's construction of s 415(1).
72 In terms of authority, Alvaro primarily concerned the Tribunal's jurisdiction, which is no longer the issue in the present appeals: see, in particular, at 218-219 per von Doussa J, for the Full Court. Justice von Doussa said that the right of review by the Tribunal of a decision of the Social Security Appeals Tribunal (SSAT) given by s 1283(1) arose where an administrative decision made in purported exercise of powers conferred by the Social Security Act had, as a matter of fact, been reviewed by the SSAT. That right existed whether or not the decision reviewed by the SSAT, or the decision of the SSAT itself, was legally effective.
73 At 220, von Doussa J said that the purpose of the review provided for by the Social Security Act was to allow the reviewing authority to correct an error and substitute a new decision where error was detected. Relevant to the present case, the SSAT by s 1253(3) was empowered for the purpose of reviewing a decision (in that case the original decision as affirmed by a Review Officer) to exercise all the powers and discretions that were conferred by the Social Security Act on the Secretary. (Our emphasis.)
74 Because of that language, we do not see the case as being of present assistance. We do however note that in considering the Tribunal's jurisdiction the Full Court did not distinguish between different types of invalidity and, at 220, said that it did not matter whether the grounds of complaint made about the preceding decision was merely that it was wrong on the merits, or that in law it was not an effective decision because it was made by someone without authority, or in excess of authority, or for improper purposes, or was vitiated through procedural irregularity such as a failure to accord natural justice. In our opinion, the present appeals concern decisions made by someone without authority.
75 Sevim v Minister for Immigration and Multicultural Affairs at [59] in our view takes the matter no further.
76 In Seymour v Migration Agents Registration Authority the issue was again one of the Tribunal's jurisdiction. The most to be extracted from the judgment, relevant to the present case, is that, consistently with the conclusion of the primary judge in the present case, the Tribunal had jurisdiction to review the decision made even though the decision-maker had no formal delegation to make the decision: at [130]. No separate argument appears to have been directed to the question of the Tribunal's powers and the reasons in Seymour do not address such an argument. As such, it is not of present assistance.
77 Kim does not seem to us to concern the present issue. The case does not deal with the powers of the Tribunal, nor is it a case where the primary decision-maker did not hold a valid delegation to exercise the power in question.
78 For completeness we add that nothing would seem to turn for present purposes on the question of a delegate exercising a power in his or her name rather than in the name of the delegator: compare Owendale Pty Ltd v Anthony, an authority relied on by the primary judge. The construction we prefer does not involve any distinction in result between, on the one hand, whether a person is a delegate and, on the other hand, whether a person is an authorised officer in the line of authorities associated with Carltona Ltd v Commissioners of Works [1943] 2 All ER 560.
79 We should however note the Minister's reliance in this Court on s 34AB of the Acts Interpretation Act. We were told that the primary judge was not referred to that provision. In our opinion, at least where there is a valid delegation, a power when exercised by the delegate shall, for the purposes of the Migration Act, be deemed to have been exercised by, here, the Minister. Contrary to the submissions on behalf of the respondents, there is no contrary intention in s 497, although it is implicit in that section that a delegate exercises the power personally. That was the position at common law which, in our opinion, is affected by s 34AB(1)(c). This conclusion suggests that the reasoning of the primary judge, with reference to Owendale, that a delegate exercises power in his or her own name, may not fully answer the question raised by s 415(1). In our view, by virtue of s 34AB of the Acts Interpretation Act, it is the delegate who in fact makes a decision but the power is deemed to have been exercised by the Minister. However, that does not necessarily mean that the Minister is the person who made the decision, within the meaning of s 415(1), if that provision is to be construed consistently with the reasoning in Brian Lawlor. In light of our earlier conclusions, it is not necessary to reach a concluded view on this issue.
80 If we are wrong on our construction of s 415(1), we would nevertheless allow the appeal on an alternative basis, which is that s 415(2) supplies the powers the primary judge held the Tribunal lacked in respect of the primary decision. Section 415(2) is not expressly limited to the exercise of the powers and discretions conferred by the Migration Act "on the person who made the decision." As we have noted, the primary judge found that the Tribunal had power only to set aside the purported decisions, which is one of the powers in s 415(2), but that the Tribunal's powers did not extend to affirming the decision, which is in another paragraph of s 415(2). The primary judge does not seem to have dealt with this argument, perhaps because it was not put to him. In our opinion, even on the approach of the primary judge, the Tribunal has the power under s 415(2) to affirm the decision under review.
81 We do not accept the submission on behalf of the respondents that ss 415(2)(a) and 415(2)(b) are constrained by s 415(1) but that s 415(2)(d) is not so constrained. In our opinion, that construction finds no foothold in the statutory language. The powers in ss 415(1) and 415(2) would seem to be distinct, because a primary decision-maker does not have the power to affirm his or her decision. Put another way, none of the powers conferred on the Tribunal by s 415(2) are powers and discretions conferred by the Migration Act on the person who made the decision: they are powers on review. The relevance and independent operation of provisions equivalent to s 415(1) is primarily in relation to other powers: see for example Commonwealth Bank Officers Superannuation Corporation Pty Ltd v Commissioner of Taxation [2005] FCAFC 244; 148 FCR 427 especially at [29]-[30]. However, the fact that the powers conferred by s 415(2) are not limited by s 415(1) does not mean they are unlimited. As s 415(4), set out at [3] above, confirms, the power to vary or substitute a decision under s 415(2) does not extend to making a decision that is not authorised by the Migration Act or Migration Regulations 1994 (Cth).
82 Neither of the bases we have given for allowing the appeal is contradicted by what was said in Kundu or Li, relied on by the primary judge: see [21] above. The present issue did not arise in those cases, which concerned circumstances where no valid application for a visa had been made.
83 Ground 3 raises a different issue. It seems to be common ground between the parties that s 476 of the Migration Act has the effect that the Federal Circuit Court has no jurisdiction to review a "primary decision" and that the decision of the purported delegate was a primary decision. The point is a technical one but it follows that if the Federal Circuit Court had no jurisdiction to review the primary decisions then, although convenient, it did not have jurisdiction to declare that the primary decisions were invalid. We do not accept the respondents' submission that there is no utility in the circumstances in setting aside Declaration 1. To the contrary, the record should not contain an order which the Federal Circuit Court had no jurisdiction to make.
84 Finally, we refer to an issue raised by the Court with the parties. This issue was the relevance, if any, of s 33AB of the Acts Interpretation Act.
85 That section provides:
Validity of things done under appointments under Acts:
Anything done by or in relation to a person purporting to act under an appointment (including an acting appointment) under an Act is not invalid merely because:
(a) …; or
(b) for any appointment - there was a defect or irregularity in connection with the appointment; or
(c) …; or
(d) ….
86 The respondents submitted that there was a distinction between an appointment and a delegation and that the requirements for the operation of the de facto officer doctrine at common law were imported into s 33AB but had not been met. The Minister in his short supplementary submissions filed, by leave, after the hearing of the appeals did not rely on the provision. The Minister noted that the Acts Interpretation Act appeared to draw a distinction between an "appointment" and a "delegation". The Minister also noted the view expressed in Pearce D, Interpretation Acts in Australia (LexisNexis Butterworths, 2018) at [7.66] where the learned author said that it was doubtful whether s 33AB applied to a delegation. For clarity, the Minister also confirmed that he had not contended and did not contend that the purported decision-maker was a de facto officer for the purposes of that doctrine.
87 It is unnecessary for us to decide the point, and we do no more than note it.
