Does failure to comply with s 418(3) invalidate AAT’s decision?

Materiality: can court speculate on counterfactual?

Federal Court (Full Court). Is it "permissible for the Court to speculate as to how the Tribunal might have reasoned or what conclusions it might have reached if it had not made the error in question"?

FAK19 extended to consequences of breaching UNCRC?

Federal Court (Full Court). Should the Tribunal should have considered, in making a decision under s 501C of the Migration Act 1958 (Cth), "the consequences for Australia of taking a decision facially contrary to the central provisions of the United Nations Convention on the Rights of the Child", based on the FCAFC's decision in FAK19? Did anything in the nature of the FCA's discretionary power with respect to costs require any particular consideration of pro bono representation?

Citizenship Act, ss 34(2)(c) and (2): retrospective only; deterrence a permissible consideration?

Federal Court. Were the tests in ss 34(2)(c) and 34(2) of the Australian Citizenship Act 2007 (Cth) retrospective only, with the assessment of risk of reoffending being of little or no relevance? In such tests, is it generally permissible for decision-makers "to have regard to such deterrence as a factor in the protection of the integrity of the naturalisation process, provided that it is not associated with a substantial purpose of pursuing retribution for or denunciation of the specific conduct engaged in by the person whose citizenship is revoked"?

Attachment missing from email: failure to make obvious enquiry?

Tribunal acting under dictation?

Federal Court (Full Court). Can it be said that acting under dictation might "occur where a decision-maker, tasked with a particular statutory function impermissibly merely adopts the decision of another body without undertaking the statutory task themselves"? If the Tribunal accepts or adopts a proposition of law, where that proposition itself was not erroneous, is the Tribunal acting under dictation?

Must discretion in s 427(1)(a) be exercised reasonably?

Federal Court. If the Tribunal's decision not to call a witness put forward by the Appellant was affected by jurisdictional error in that it lacked an evident and intelligible justification, could that error also be identified as a failure to take into account a relevant consideration (that the witness' oral evidence may assist the Tribunal to determine the Appellant's claim to be a refugee)?

AAT: illogical decision involving expert report

Federal Court: Was the AAT obliged to call a psychologists for cross-examination? Was the AAT's reason illogical on the basis that, on the one hand, it expressed 'concerns about the reliability of the final conclusions in relation to recidivism presented in the reports of both [psychologists]' and, on the other hand, 'proceeded to accept both those assessments and use them effectively as bookends to a range which is expressed by the AAT as “‘low’ to ‘low to moderate’ risk” that the applicant will re-offend'?

Nathanson expanded to failure to consider claim or evidence?

Federal Court. In Nathanson, Kiefel CJ, Keane and Gleeson JJ held in the context of a denial of procedural fairness that the standard of reasonable conjecture, used to determine whether an error was material and thus jurisdictional, was "undemanding". Is a reasonable conjecture applicable in the context of an assessment of the materiality of errors in the form of a failure to consider a claim or evidence in support of a claim? If so, is the standard of reasonable conjecture also undemanding in such a context?
