Ground 4
33 In relation to this ground of appeal, the appellant submitted, in summary, that the use of the word "revoke" implies that the only person who can revoke the decision is the person who made it. In so submitting, the appellant relied on the decision of this Court in Minister for Immigration & Multicultural & Indigenous Affairs v Watson (2005) 145 FCR 542 at [106]. To that extent, in the submission of the appellant, "revoke" can be distinguished from such terms as "set aside".
34 The Minister submitted, in summary:
there is nothing in s 501CA to support the limited construction for which the appellant contended;
the power exercised under s 501CA is a distinct and separate power from that exercised under s 501(3A). It can be contrasted with the power granted by s 501C;
Watson 145 FCR 542 is not relevant to this aspect of the appellant's case.
35 In my view this ground of appeal is not substantiated.
36 As Gibbs CJ observed in O'Reilly v State Bank of Victoria Commissioners (1983) 153 CLR 1 at 11, the answer to the question whether a statute requires a power to be exercised personally by the person designated depends on the nature of the power and all the other circumstances of the case (cf Brennan J in Re Reference under section 11 of Ombudsman Act 1976 for an advisory opinion; Ex parte Director-General of Social Services (1979) 2 ALD 86 at 93).
37 It is common ground that, in individual circumstances, the power granted by s 501CA(4) to revoke a visa cancellation decision may be exercised by the Minister or a delegate of the Minister. That a delegate of the Minister may have the power to revoke a visa cancellation decision is notwithstanding that:
section 501CA itself is couched in terms referring only to decisions of "the Minister", and
section 501CA makes no specific reference to decisions of delegates.
38 Clearly, s 496 of the Migration Act empowers the Minister, by writing, to delegate to any person any of the Minister's powers under the Migration Act, including the power to revoke a cancellation decision, and to that extent gives effect to the so-called Carltona principle whereby Ministers of the Crown may properly delegate administrative functions to Departmental officials (Carltona Ltd v Commissioners of Works [1943] 2 All ER 560; O'Reilly 153 CLR 1; Dooney v Henry (2000) 174 ALR 41; [2000] HCA 44). That this is further so in respect of powers conferred by s 501CA(4) is evident, for example, from the terms of s 500(1)(ba) of the Migration Act, which permits applications to be made to the Administrative Appeals Tribunal in respect of:
(ba) decisions of a delegate of the Minister under subsection 501CA(4) not to revoke a decision to cancel a visa.
39 While relevant instruments of delegation by the Minister pursuant to s 501CA(4)(b) were not produced in Court (and, it appears, are not in the public arena), the terms upon which delegates may exercise power in accordance with s 501CA(4)(b) are set out in Direction No 65, made by the Minister pursuant to s 499 of the Migration Act, which:
Contains the Objectives of this Direction, General Guidance for decision-makers and the Principles that provide a framework within which decision-makers should approach their task of deciding whether to exercise the discretion to cancel or refuse a non-citizen's visa under section 501 or to revoke a mandatory cancellation under section 501CA.
40 The interpretation of s 501CA(4)(b) promoted by appellant - namely that it is only the delegate who can revoke that delegate's visa cancellation decision (and presumably only the Minister who can revoke a visa cancellation decision of the Minister) - would produce an inflexible practical outcome for which neither statutory nor policy justifications have been advanced. This interpretation would result, for example, in operative inconvenience if the relevant delegate left the Department, or the position of the delegate were reclassified. The proposed construction also ignores the point I have already made, namely that in exercising the power under s 501CA(4)(b) the delegate is actually exercising an administrative power of the Minister, and it follows that any power of revocation is similarly vested in the Minister.
41 To that extent it follows that a visa cancellation decision of a delegate can be revoked by either the delegate or the Minister.
42 In relation to the submissions of the appellant concerning the decision of this Court in Watson 145 FCR 542, I note that the Court in that case examined an earlier iteration of the Migration Act prior to the enactment of s 501CA, which conferred an express power on the Minister to revoke a visa cancellation decision. In the course of considering whether the Migration Act (as then enacted) impliedly empowered the Minister to revoke a visa cancellation decision, both Hely J (at [15]) and Lander J (at [93]-[95]) concluded that the reference in s 501E(1) and s 501F(2) (as then drafted) to the decision being "set aside" was to the decision being set aside by the Administrative Appeals Tribunal, and that the reference to the decision being "revoked" was a reference to the exercise by the Minister of the power conferred by s 501C(4) of the Act. It is important however to consider the context in which these conclusions were reached.
43 In particular, as Lander J observed at [52]-[55], at that time s 501(1) and (2) empowered the Minister or a delegate of the Minister to refuse to grant a visa to a person or to cancel a visa that had been granted to a person in the circumstances contemplated by the subsections. At the same time, s 501(3) empowered the Minister and only the Minister (s 501(4)) to refuse to grant a visa to a person or to cancel a visa that had been granted to a person if the Minister reasonably suspected that the person did not pass the character test and the Minister was satisfied that the refusal or cancellation was in the national interest. His Honour noted that a decision made by a delegate could be reviewed by the Administrative Appeals Tribunal and set aside, whereas a decision of the Minister was not similarly subject to such review or to being set aside (s 500(1)(b), s 500(4)).
44 His Honour noted further, for example that:
section 501A(2) and s 501A(3) empowered the Minister to "set aside" decisions of the delegate or the Tribunal, and that s 501B(2) empowered the Minister to "set aside" relevant decisions of a delegate;
this could be contrasted with the power of the Minister under s 501(4) and s 501(5) to "revoke" his own decision;
section 501E referred to decisions of the Minister made under ss 501, 501A, 501B which had been "neither set aside nor revoked".
45 While the observations of the Court in Watson 145 FCR 542 are pertinent to the consideration of the appellant's argument concerning the meaning of "set aside" and "revoke", they are otherwise of limited assistance in construing s 501CA(4). The observations in Watson 145 FCR 542 were made in the context of provisions of the Migration Act predating the enactment of those under consideration in this case. There are numerous instances in the Migration Act as presently enacted where the Minister is empowered to "set aside" particular decisions of a delegate or the Administrative Appeals Tribunal, but in the context of original decisions which were made only by a delegate or the Administrative Appeals Tribunal. Examples of this are in:
section 501A (power of the Minister to set aside a decision of a delegate or the Administrative Appeals Tribunal not to exercise powers conferred by s 501(1) and s 501(2));
section 501B (power of the Minister to set aside a decision of a delegate under s 501(1) or s 501(2) to refuse to grant a visa to a person or to cancel a visa that had been granted to a person);
section 501BA (power of the Minister to set aside a decision of a delegate or the Administrative Appeals Tribunal, but in circumstances where the decision was made by either of those entities under s 501CA to revoke a decision under subs 501(3A) to cancel a visa that had been granted to a person).
46 This can be contrasted with s 501CA, which specifically addresses revocation of decisions under s 501(3A), which decisions which could in individual circumstances be made by either the Minister or a delegate.
47 Further, as is clear from a perusal of the Migration Act, a number of powers conferred by the legislation can be exercised only by the Minister personally, for example those exercisable under s 500A(1) and (3) (as mandated by s 500A(6)), s 501(3) (as mandated by s 501(4)), s 501A(2) and (3) (as mandated by s 501A(5)), s 501B(2) (as mandated by s 501B(3)), s 501BA(2) (as mandated by s 501BA(4)). This is not the case in relation to decisions under s 501CA(4). There is no statutory mandate in s 501CA which limits either the Minister or a delegate to personally exercise the power conferred by that section - it is common ground that the power conferred by s 501CA can be exercised by either the Minister or a delegate.
48 The use of the word "revoke" in this context does not limit the exercise of the power to the maker of the original decision. A decision of the Minister's delegate made in accordance with s 501(3A) of the Migration Act, which decision was made by the delegate in exercise of the powers of the Minister, can be revoked by the Minister. The primary Judge so found at [55]-[61] - in my view correctly.
