First limb of Tribunal's reasoning
49 Counsel for the appellants submitted that there was no way in which a logical or rational decision maker could conclude that the First Appellant's mother was "equally responsible" or "equally culpable" for the relationship or the cousin's death on the basis only that she had not maintained constant vigilance and control over her daughter and her niece.
50 He submitted that in view of the Tribunal's acceptance, at least implicitly, of the First Appellant's account that the relationship between the cousin and the worker would not have occurred without her actions, only one conclusion was open on the evidence, namely that the First Appellant bore greater responsibility for the relationship between the cousin and the worker and, by extension, for the cousin's subsequent suicide, than her mother.
51 Further he submitted that even if one could view the question of "responsibility" or "culpability" for the cousin's suicide in the way that the Tribunal had, that did not provide any logical basis for a finding that the uncle also viewed the situation in that way. He contended that the question of "who was objectively responsible for [the cousin] meeting [the worker]" was a very different question to "who does [the uncle] blame for [the cousin's] death".
52 The appellants' counsel contended that, even if it had been open to the Tribunal to conclude that the First Appellant and her mother were "equally responsible" for the cousin's death, and that they were therefore "equally" at risk, this would not of itself provide a logical or rational basis for a finding as to who the uncle thought was responsible for the cousin's death or how the uncle proposed to respond. He submitted that to reason otherwise would be to rely upon unexpressed and unwarranted assumptions without any basis in the material before the Tribunal or to engage in mere speculation about matters beyond the scope of ordinary human experience.
53 There is considerable force in the submissions made by counsel for the appellants that the Tribunal embarked on an objective assessment of respective responsibility for the cousin's death in reaching its conclusion that the First Appellant and her mother were equally responsible, rather than attempting to determine who the uncle thought was responsible for the cousin's death.
54 It would appear that the Tribunal, in the absence of any evidence as to the uncle's perceived attribution of responsibility, has determined by reference to its own evaluative judgment of respective responsibility that the First Appellant and her mother were "equally culpable".
55 As acknowledged by counsel for the Minister, however, the relevant attribution of responsibility was subjective, in the sense of a determination of how would the uncle have been expected to attribute responsibility for his daughter's death, rather than an objective assessment made by the Tribunal informed by its own assessment of respective responsibility.
56 The objective approach of the Tribunal to the "responsibility issue" is reflected in the "difficulty to identify a substantially higher level of responsibility" and "makes her equally culpable" passage of the reasoning of the Tribunal, reproduced at [29] above.
57 As submitted by counsel for the Minister, however, the Tribunal's reasons should not be examined "with an eye keenly attuned to the perception of error" or "with a fine appellate tooth-comb, against the prospect that a verbal slip will be found warranting the inference of an error of law": Collector of Customs v Pozzolanic Enterprises Pty Ltd (1993) 43 FCR 280; [1993] FCA 456 at 287 (Neaves, French and Cooper JJ); Minister for Immigration and Ethnic Affairs v Wu Shan Liang (1996) 185 CLR 259; [1996] HCA 6 at 291 (Kirby J).
58 Having embarked on an exercise of seeking to determine the respective responsibility of the First Appellant and her mother for the death of the cousin, on one view given the absence of any specific evidence as to how the uncle assessed "respective responsibility" the only course available to the Tribunal was to engage in an objective examination of the evidence before it and draw inferences as to how the uncle was likely to assess "respective responsibility".
59 Ultimately, I am not persuaded that the approach taken by the Tribunal could not have been taken by a logical or rational decision-maker.
60 Nor am I persuaded that the finding made by the Tribunal, that the First Appellant and her mother would have been considered by the uncle to have been equally responsible for the death of the cousin, was a finding that could not have been made by a logical or rational decision-maker.
61 As submitted by counsel for the Minister, this was a finding that was rationally open to the Tribunal, and in relation to which its reasons revealed an evident and intelligible justification: the First Appellant's mother was responsible for bringing the worker to the vineyard, allowing the cousin to accompany the First Appellant to serve the workers in circumstances where the First Appellant was only 19 years old at the time and her mother had ultimate responsibility for the workforce.
62 I note that this was the finding, in substance, made by the Delegate and the previously constituted Tribunal. While not determinative, those findings provide a further impediment against a finding that the Tribunal's reasoning with respect to the equal attribution of responsibility was so illogical that no rational or logical decision maker would have so reasoned.
