Consideration
25 Dr Ogawa's amended originating application asserts that the delegate's decision was so unreasonable that no reasonable person could have exercised the power in that way.
26 Although Dr Ogawa was given leave to amend her originating application to include grounds that there was a denial of procedural fairness, and that the decision-maker failed to take into account relevant considerations and took into account irrelevant considerations, those grounds have not been included. Dr Ogawa did not address those grounds in her submissions. I will proceed on the basis that they are no longer pursued.
27 The amended originating application retains the allegation contained in the original that there was unreasonable delay in making the decision. However, that allegation was only relevant to Dr Ogawa's application for orders requiring the Minister to make a decision. That part of the application has been overtaken by the decision having been made on 2 March 2020. Accordingly, that part of the application falls away.
28 In written submissions filed on 2 March 2020, Dr Ogawa said that the case raises only one question, namely:
Is it reasonable for the Respondent to decide that an overseas student from a non-English speaking country, studying on scholarship, with no legal qualification or training in this country should be responsible for the whole consequences of the anomaly in Commonwealth legislation, the failure of a Commonwealth quasi-judicial institution to make a decision within the timeframe and the maladministration of a Commonwealth Department (of Immigration) in handling the Applicant's case, while the Commonwealth including the Respondent has done nothing to rectify those Commonwealth's mistakes?
29 In oral submissions, Dr Ogawa said that the original debt concerned her dispute against the University of Melbourne. She asserted that the Department had wrongly cancelled her visa, and she went to the Migration Review Tribunal (the MRT), which made a decision in her favour. She said that in the meantime, her student visa had expired. She said that the Regulations now allow a new application for a visa to be made within 28 days of the decision of the AAT, but at that time there was no equivalent provision. She said that was an anomaly which meant that she could not get her student visa back and caused the litigation and her immigration detention. She said that the Courts were unable to fix the problem caused by the anomaly, but had recognised it in their decisions.
30 Dr Ogawa said that she had applied for another student visa but it was not granted because of the outstanding Commonwealth debt. She submitted that her difficulties existed because of the Commonwealth debt, and the Commonwealth debt existed due to the anomaly in the Regulations and the failure of the MRT to make a decision quickly.
31 Dr Ogawa argued that while the delegate said that it was her decision to litigate, without the litigation she would have been detained and deported. She submitted that the Commonwealth Ombudsman made a recommendation to waive the debt and the AHRC had tried to reduce the debt.
32 Dr Ogawa said that the costs she was awarded by the Full Court should not have been set off against her debt to the Commonwealth. She said that by setting off the debt, the lawyers who acted for her had not been paid.
33 The Minister submitted that the delegate's decision was open on the material before the delegate and was not legally unreasonable.
34 The delegate's decision was made under the discretionary power conferred upon the Minister by s 63(1)(a) of the Public Governance Act. The sole ground of review relied upon is that the delegate's decision was legally unreasonable.
35 In Minister for Immigration and Citizenship v Li (2013) 249 CLR 332, Hayne, Kiefel and Bell JJ held at [63] that the legislature is taken to intend that a discretionary power, statutorily conferred, will be exercised reasonably.
36 In Minister for Immigration and Border Protection v SZVFW (2018) 264 CLR 541, Kiefel CJ succinctly explained the ground of legal unreasonableness:
10 In the joint judgment in Minister for Immigration and Citizenship v Li it was explained that a decision made in the exercise of a statutory power is unreasonable in a legal sense when it lacks an evident and intelligible justification. That may be so where a decision is one which no reasonable person could have arrived at, although an inference of unreasonableness is not to be drawn only where a decision appears to be irrational. None of these descriptions could be applied to the Tribunal's decision in the present case.
11 Statements such as that made in the Wednesbury case, that a decision may be regarded as unreasonable if no reasonable person could have made it, may not provide the means by which a conclusion of unreasonableness may be arrived at in every case. But it serves to highlight the fact that the test for unreasonableness is necessarily stringent. And that is because the courts will not lightly interfere with the exercise of a statutory power involving an area of discretion. The question is where that area lies.
37 The delegate decided not to waive the debt because he considered, inter alia, that debts "established" by an order of a Court should not ordinarily be waived; that the debt resulted from Dr Ogawa's choice to engage in litigation; that her detention and the associated litigation had resulted from her own conduct in failing to take steps to regularise her visa status; and that she had the capacity to obtain employment which would allow her to pay off the debt.
38 It is not enough for Dr Ogawa to merely assert that a different decision should have been made by arguing, as she has, that particular factors should have been interpreted differently, assessed differently, or weighted differently. Based on the material before the delegate, his findings and the ultimate decision were logical and rational. It has not been demonstrated that the delegate's exercise of discretion lacked an evident and intelligible justification. Further, it has not been demonstrated that the decision was one which no reasonable person could have made.
39 The ground of legal unreasonableness cannot succeed. The amended originating application must be rejected.
