The grounds of review
8 The grounds upon which review of the Tribunal's decision is sought in this Court are expressed as follows in Mr Tohi's Amended application for review of a migration decision as filed in July 2020 (without alteration):
1. The second respondent (the Tribunal) made a finding of fact which was irrational and legally unreasonable.
Particulars
The Tribunal made a finding:
i) that the applicant was at a 'moderate risk of reoffending' [at par. 48];
ii) such a finding had no evidentiary basis.
2. The Tribunal's finding, at [48], that there was a 'low to moderate' risk that the applicant would reoffend, is inconsistent with its finding [at 92] that there is a dearth of evidence it wont happen again'.
9 No extensive analysis of legal principle is required to resolve these two grounds. But some generally accepted principles should nevertheless be stated.
10 First, it is common ground that any application for judicial review needs to establish some legal error and does not extend to a review of the factual merits of the decision under review: Attorney-General (NSW) v Quin (1990) 170 CLR 1 at 35-36 ("Quin"). Brennan J (as his Honour then was) there observed:
The duty and jurisdiction of the court to review administrative action do not go beyond the declaration and enforcing of the law which determines the limits and governs the exercise of the repository's power. If, in so doing, the court avoids administrative injustice or error, so be it; but the court has no jurisdiction simply to cure administrative injustice or error. The merits of administrative action, to the extent that they can be distinguished from legality, are for the repository of the relevant power and, subject to political control, for the repository alone.
His Honour further observed at 38:
If judicial review were to trespass on the merits of the exercise of administrative power, it would put its own legitimacy at risk.

11 Second, legal error is not exposed in respect to a finding of fact provided there is "some basis" for the finding made, and legal error is not exposed at common law even if there is some "illogical reasoning": Australian Broadcasting Tribunal v Bond (1990) 170 CLR 321 at 356. Mason CJ there summarised the position as follows:
But it is said that "[t]here is no error of law simply in making a wrong finding of fact": Waterford v. The Commonwealth [((1987) 163 CLR 54 at 77] per Brennan J. Similarly, Menzies J. observed in Reg. v. District Court; Ex parte White [(1966) 116 CLR 644 at 654]:
"Even if the reasoning whereby the Court reached its conclusion of fact were demonstrably unsound, this would not amount to an error of law on the face of the record. To establish some faulty (e.g. illogical) inference of fact would not disclose an error of law."
Thus, at common law, according to the Australian authorities, want of logic is not synonymous with error of law. So long as there is some basis for an inference - in other words, the particular inference is reasonably open - even if that inference appears to have been drawn as a result of illogical reasoning, there is no place for judicial review because no error of law has taken place.
12 Third, there is limited scope for judicial intervention if a conclusion or finding is "unreasonable" - but to establish such a case is not easy. The circumstances are "confined". In Quin, Brennan J there summarised the position as follows (at 36):
… Properly applied, Wednesbury unreasonableness leaves the merits of a decision or action unaffected unless the decision or action is such as to amount to an abuse of power … Acting on the implied intention of the legislature that a power be exercised reasonably, the court holds invalid a purported exercise of the power which is so unreasonable that no reasonable repository of the power could have taken the impugned decision or action. The limitation is extremely confined.

Similarly, in Minister for Immigration and Citizenship v Li [2013] HCA 18, (2013) 249 CLR 332 at 351-352. French CJ again emphasised as follows the need to ensure that judicial scrutiny did not trespass into the merits of a decision:
[30] The requirement of reasonableness is not a vehicle for challenging a decision on the basis that the decision-maker has given insufficient or excessive consideration to some matters or has made an evaluative judgment with which a court disagrees even though that judgment is rationally open to the decision-maker. Gleeson CJ and McHugh J made the point in Eshetu that the characterisation of somebody's reasoning as illogical or unreasonable, as an emphatic way of expressing disagreement with it, "may have no particular legal consequence" [Minister for Immigration and Multicultural Affairs v Eshetu (1999) 197 CLR 611 at 626].
The caution consistently exercised by a court undertaking judicial review in avoiding trespassing into the merits of an administrative decision is reflected in some judicial language which requires "extreme" illogicality to be demonstrated: e.g., Minister for Immigration and Citizenship v SZRKT [2013] FCA 317 at [148], (2013) 212 FCR 99 at 137 per Robertson J. Such language may do nothing more than give emphasis to the proposition that illogicality or irrationality is not exposed where "probative evidence can give rise to different processes of reasoning and if logical or rational or reasonable minds might differ in respect of the conclusions to be drawn from that evidence": Minister for Immigration and Citizenship v SZMDS [2010] HCA 16 at [131], (2010) 240 CLR 611 at 648 per Crennan and Bell JJ.
13 Fourth, reasons for an administrative decision are not to be judicially scrutinized with a view to the detection of error by reason of a looseness of language: Minister for Immigration and Ethnic Affairs v Liang (1996) 185 CLR 259 at 271-272 ("Liang"). Brennan CJ, Toohey, McHugh and Gummow JJ there made the following observations as to the approach to be taken when reviewing the reasons provided by an administrative decision-maker:
When the Full Court referred to "beneficial construction", it sought to adopt an approach mandated by a long series of cases, the best exemplar of which is Collector of Customs v Pozzolanic [(1993) 43 FCR 280]. In that case, a Full Court of the Federal Court (Neaves, French and Cooper JJ) collected authorities for various propositions as to the practical restraints on judicial review. It was said that a court should not be "concerned with looseness in the language ... nor with unhappy phrasing" of the reasons of an administrative decision-maker [(1993) 43 FCR 280 at 287]. The Court continued [(1993) 43 FCR 280 at 287]: "The reasons for the decision under review are not to be construed minutely and finely with an eye keenly attuned to the perception of error."
These propositions are well settled. They recognise the reality that the reasons of an administrative decision-maker are meant to inform and not to be scrutinised upon over-zealous judicial review by seeking to discern whether some inadequacy may be gleaned from the way in which the reasons are expressed [McAuliffe v Secretary, Department of Social Security (1992) 28 ALD 609 at 616]. In the present context, any court reviewing a decision upon refugee status must beware of turning a review of the reasons of the decision-maker upon proper principles into a reconsideration of the merits of the decision. …

14 The expression of these principles in such a general manner unquestionably conceals many subtleties - but it provides a sufficient background to the resolution of the two Grounds now relied upon by Mr Tohi.
