Case Law Updates

High Court: Should an appellate court make its own finding of fact only where the trial judge's finding of fact was "glaringly improbable" or "contrary to compelling inferences"? Whatever the answer is, it arguably applies to migration matters.

Federal Court (Full Court): in a separate  (but not in dissent) judgement, Mortimer J held that the High Court's materiality test in Hossain did not apply to procedural fairness and legal reasonableness

Federal Court. Given the Tribunal's extensive references to the Applicant's drug addiction throughout its reasons, can it realistically be supposed that the Tribunal overlooked that addiction in concluding generally that he was "apparently in good health" for the purpose of cl 9.2(1)(a) of Direction 90?

Federal Court (Full Court). Can the Tribunal act on its personal or specialised knowledge and on matters which are commonly known? Does the discharge of the onus placed on the judicial review applicant to prove that a finding by the Tribunal, which required evidence but was one in respect of which there was not a skerrick of evidence, was material to the outcome require proof that the finding was erroneous?

High Court: Plaintiff sentenced to imprisonment for life, with a non-parole period. Just before plaintiff became eligible to apply for parole, legislation changed in a way that his eligibility was severely constrained. Did the legislative change represent resentencing or repunishment, thus offending the separation of powers? Does the fact that the legislative change expressly singled out the plaintiff have any bearing on how that question should be answered? If the legislation was valid, could migration legislation also validly single out an individual?

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 reasonable conjecture applicable in the context of an assessment of the materiality of errors in the form of misinterpretation of s 473DD of the Migration Act 1958 (Cth)? If so, is the standard of reasonable conjecture also undemanding in such a context?

Federal Court (Full Court). Was the Full Court's decision in CWY20 contradicted by the High Court's decision in Plaintiff M1-2021 v Minister for Home Affairs [2022] HCA 17?

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?

Federal Court. Can it be said in the context of s 501CA(4) of the Migration Act 1958 (Cth) that, "in any particular case, the practical reality of a person’s situation may be such that although there are theoretical avenues by which their immigration detention might be brought to an end, no such avenue presently has any realistic possibility of materialising"?

Federal Court (Full Court). Can the literality of words of judgments be interpreted as if they were the text of a statute? Can secondary materials such as an explanatory memorandum only be looked at if the text of a statute is ambiguous?
