26 According to Counsel for the Minister, the Federal Magistrate in the present case, by implication, distinguished Yu because, in that case, there had apparently been no notice under the Overseas Students Act. Accordingly, Counsel for the Minister imputed to his Honour the view that, in the passage just quoted, Allsop J was addressing only the question of whether the exercise of the power of cancellation under s 116 of the Migration Act was conditioned upon the giving of such a notice. Allsop J had not, in terms, dealt with the effect of a notice which had been given in purported reliance on s 20 but was, presumptively, invalid. Counsel for the Minister submits that, however, did not afford a proper basis for distinguishing Yu because the power conferred by s 116 was not conditioned exclusively on the service of a notice under s 20 of the Overseas Students Act. He contends this is confirmed by the decision in Gerhard v Minister for Immigration and Multicultural and Indigenous Affairs [2003] FCA 495 where Ryan J had observed, at [17]:
'Section 20 of the Overseas Students Act is not determinative of the attainment of satisfaction postulated by s 116 of the Act. The latter makes no reference to the Overseas Students Act which is not surprising since the relevant provisions of s 116 have remained in their present form since before the Overseas Students Act or the Migration Legislation Amendment (Overseas Students) Act 2000 (Act No 168 of 2000) were passed. Likewise condition 8202 was not amended in the light of the Overseas Students Act and related legislation. Accordingly, the validity of a notice under s 20 of the Overseas Students Act is not a prerequisite for cancellation of a student visa under s 116 although it may, as Counsel for the Minister accepted, be essential for cancellation pursuant to s 137J which was inserted into the Act by the Migration Legislation Amendment (Overseas Students) Act 2000. A cancellation under s 116 must occur upon the Minister's attainment of the requisite satisfaction even if the process has been initiated on the Minister's own motion or otherwise without the issue of a notice under s 20 of the Overseas Students Act. Once that is understood, s 116(3) leaves no discretion to the Minister or the MRT once he or it is satisfied that the holder has not achieved an academic result that is certified by the education provider as at least satisfactory. For a similar view of the effect of s 116(3) in excluding any discretion see Ariyagama v Minister for Immigration and Multicultural Affairs [2001] FCA 1407 [20], Nguyen v Minister for Immigration and Multicultural Affairs [2002] FCA 460 [11] and Akter v Minister for Immigration and Multicultural and Indigenous Affairs [2002] FCA 1504 [20].'
27 According to Counsel for the Minister, the Federal Magistrates Court erred in the present case by regarding a mere factual, causal, connection between the s 20 notice and the initiation of the cancellation process under s 116 of the Migration Act as affecting the validity of a decision mandated by the latter section. He submits that the duty imposed by s 116 could not be abrogated by any antecedent or legal error which brought about the circumstances in which the duty came to be performed: Jadwan v Secretary, Department of Health and Aged Care (2005) 145 FCR 1; (2004) 204 ALR 55, at [56] and Zhou v Minister for Immigration and Multicultural and Indigenous Affairs (2004) 139 FCR 60 at [43].
28 Counsel for the Minister also relies upon consideration given to the issues raised in this appeal in other decisions. Firstly, he relied on Humayun v Minister for Immigration and Multicultural and Indigenous Affairs [2006] FCAFC 35. Like the present appeal, Humayun concerned a decision of the MRT to affirm a decision by a delegate to cancel a student visa pursuant to s 116 of the Migration Act. The appellant in Humayun had been sent a notice pursuant to s 20 of the Overseas Students Act in respect of a breach of condition 8202 of his student visa. It was relevantly in the same form as the s 20 notice given by M/s Zhou's education provider in the present appeal. In response to the s 20 notice that appellant reported to the Department and attended an interview, at the end of which he was advised of the decision to cancel his visa. The Minister contended in Humayun that, even if the s 20 notice was incapable of having the consequences set out in Subdivision GB of the Div 3 of the Migration Act (ss 137J - 137P), that did not affect the power of the delegate to effect a visa cancellation under s 116 of the Migration Act. Further, the Minister contended there that a legal deficiency in the delegate's decision would not affect the power of the MRT to review the purported decision and to make such order as the delegate ought to have made. Wilcox J (with whom Conti and Stone JJ relevantly agreed) accepted each of these submissions. The Full Court's acceptance of the Minister's first submission also involved its acceptance of the correctness of what was said by Allsop J (with Tamberlin J agreeing) in Yu.
29 The submissions for the Minister therefore also contain the submission that the "defects" said to exist in the s 20 notice and identified in Uddin are immaterial here given that the decision under review is a decision of the MRT to affirm a cancellation decision made under s 116 of the Migration Act. It is not a challenge to an automatic cancellation of a visa pursuant to s 137J of the Migration Act.
30 The Full Court decision in Humayun was recently followed and applied by Siopis J in Shek v Minister for Immigration and Multicultural and Indigenous Affairs [2006] FCA 522 at [41]-[45].
31 In a subsidiary way, Counsel for the Minister contends that, even if the primary contention be rejected, the s 20 notice in the present case conformed with the relevant statutory requirements and was not misleading. It faithfully followed the formula to be found in s 20(4)(b) of the Overseas Students Act and, properly construed, called on M/s Zhou to explain only her "alleged breach" of condition 8202. To the extent that the dicta of the Full Court in Morsed (supra) suggested that a s 20 notice in the present form is misleading or creates a "trap" for an applicant, they should not be followed and, in any event, did not go so far as to say that any defect in such a notice can negate or prejudice the achievement of the purposes of s 116(3) of the Migration Act read in conjunction with reg 2.43(2)(b)(ii) of the Migration Regulations.
