Ground 1 - failure to consider a clearly articulated claim
20 The principles concerning the obligation of the Tribunal to consider a claim relied upon by an applicant before it are not in dispute. The Tribunal would fail to perform its duty "if it failed to take account of a substantial and clearly articulated argument advanced by the applicant in support of [their] case": Minister for Immigration and Border Protection v SZMTA (2019) 264 CLR 421; [2019] HCA 3 at 436 [13], citing Dranichnikov v Minister for Immigration and Multicultural Affairs (2003) 77 ALJR 1088; [2003] HCA 26 at 1092 [24]-[25]. In NABE v Minister for Immigration and Multicultural and Indigenous Affairs (No 2) (2004) 144 FCR 1; [2004] FCAFC 263 at 20 [63], it was said that:
… a failure by the Tribunal to deal with a claim raised by the evidence and the contentions before it which, if resolved in one way, would or could be dispositive of the review, can constitute a failure of procedural fairness or a failure to conduct the review required by the Act and thereby a jurisdictional error.
21 Whether or not a matter has been considered can be a matter of inference drawn from the reasons as a whole: Jabari v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs (2023) 298 FCR 431; [2023] FCAFC 98 at 445 [55]. In Plaintiff M1/2021 v Minister for Home Affairs (2022) 275 CLR 582; [2022] HCA 17, Kiefel CJ, Keane, Gordon and Steward JJ said (at 598-9 [24]):
Consistently with well-established authority in different statutory contexts, there can be no doubt that a decision-maker must read, identify, understand and evaluate the representations. Adopting and adapting what Kiefel J (as her Honour then was) said in Tickner v Chapman [(1995) 57 FCR 451 at 495], the decision-maker must have regard to what is said in the representations, bring their mind to bear upon the facts stated in them and the arguments or opinions put forward, and appreciate who is making them. From that point, the decision‑maker might sift them, attributing whatever weight or persuasive quality is thought appropriate. The weight to be afforded to the representations is a matter for the decision-maker. And the decision-maker is not obliged "to make actual findings of fact as an adjudication of all material claims" made by a former visa holder.

22 These statements of principle derive from the context of particular kinds of decision-making under the Migration Act 1958 (Cth). Precisely what is required must ultimately be a matter of statutory construction arising from a consideration of the particular decision, the surrounding circumstances in which it is to be made and the nature of the hearing in the Tribunal. The parties accepted, however, that these principles were generally applicable to the function of the Tribunal in the present case.
23 Ms Lyall contends that the Tribunal failed to consider a clearly articulated claim, namely the claim recorded by the Tribunal at [112] that she "suspect[ed] that she was reporting as otherwise the debt would have been raised earlier". That claim and the way the Tribunal responded to it must be understood against the background of the discussion and findings earlier in the reasons of the Tribunal.
24 That discussion indicates that Ms Lyall had also advanced an essentially similar claim in different terms. She advanced a positive case that she had in fact reported the change in circumstances that arose from her employment with Healthscope. The claim that Ms Lyall "suspect[ed]" that "she was reporting" was, in substance, a weaker version of that claim, framed in terms of speculation rather than a direct contention. In substance, however, the fact that Ms Lyall made the claim required the Tribunal to consider whether or not it was satisfied that she had not reported the change in her circumstances to the Department when she began working for Healthscope.
25 The Tribunal expressly set out, at [112], Ms Lyall's contention that she suspected that she was reporting. It then immediately set out its conclusion that Ms Lyall knowingly failed to comply with the notice at [113]. The Tribunal cannot have "overlooked" the claim, given that it set it out in the reasons immediately before expressing its conclusion. Ms Lyall's contention was that the Tribunal had not addressed the claim by way of reasons or conclusion.
26 The Tribunal's reasons at [113], when read together with the earlier discussion at [79]-[86] of its reasons (which I have set out at [18] above), indicate clearly enough that the Tribunal did not accept that Ms Lyall did in fact report changes to her income, and found that she had conversations with officers of Centrelink in the terms recorded by them. The Tribunal evidently regarded it as inherently improbable that Ms Lyall's conversations with Centrelink officers were repeatedly incorrectly recorded. It is implicit in what the Tribunal said at [113] that it accepted that Ms Lyall did in fact have conversations to the effect recorded by the Centrelink officers and set out in the reasons of the Tribunal at [80] and [82]. Those conversations as recorded included acceptance by Ms Lyall that she knew that she was required to inform Centrelink if she commenced work, or commenced earning income, and included an apology for not reporting her income from the Healthscope employment. Although the reasoning actually recorded in [113] is economically expressed, that is readily explicable by the fact that the Tribunal had already addressed the terms of the notes of the Centrelink officers which appeared on Ms Lyall's file earlier in its reasons, had accepted that it was prepared to act on the basis that the notes were accurate, and had accepted that Ms Lyall did not report her income. I do not consider that the terms of [113] indicate that the Tribunal overlooked or failed to deal with the claim that Ms Lyall had received income in the past, or that she "suspected" that she had.
27 The claimed "suspicion" that Ms Lyall had reported her income in the period when she was working for Healthscope was said to be supported by Ms Lyall's submission that "otherwise the debt would have been raised earlier". That submission was not such as to require the provision of a separate express answer in order for the Tribunal to fulfil its obligation to give reasons. What the Tribunal was required to set out was its own reasons for the decision it reached. It was open to the Tribunal to rely on its conclusion that the Centrelink officers had accurately recorded their conversations with Ms Lyall as a matter sufficient to conclude that Ms Lyall had not reported her income as she "suspected" she had.
28 Ms Lyall submitted that the issue which the Tribunal addressed at [78]-[86] of its reasons was different from that which it addressed at [112]-[113]. The reasoning and findings at [78]-[86] were directed to the question of whether the debt arose wholly or partly because Ms Lyall had "failed to provide information in relation to [her] income from personal exertion", which arose under s 1228B(1)(c) of the Act. I accept that was a different statutory question than that which arose under s 1237AAD of the Act, but the factual findings made by the Tribunal in the earlier part of its reasons were also directly relevant to the latter issue. The Tribunal's reasons and conclusions at [78]-[86] were only consistent with a conclusion that Ms Lyall had knowingly failed to inform the Department of her work for Healthscope and the change in her income.
29 Ms Lyall also placed reliance on [116] of the Tribunal's reasons where it found that it was prepared to infer that Ms Lyall had not knowingly failed to report the income to which Debt 2 related. Debt 2 arose during a different period, in which Ms Lyall had been reporting income, but had under-reported the amount of income. The Tribunal's conclusion with respect to Debt 2 is not inconsistent with its conclusion that Debt 1 arose from a knowing failure by Ms Lyall to report income, and it does not suggest a failure by the Tribunal to engage with the evidence or submissions relating to Debt 1.
30 For these reasons, ground 1 is not established.
