Ground 3: Illogical, irrational or unreasonable finding
114 Ground 3 concerns whether the Minister's finding that there was a "low likelihood that Ms Palmer would reoffend" (at MD[77]) was so illogical, irrational or unreasonable that the Minister's Decision was affected by jurisdictional error. Ms Palmer submitted that rather than there being a "low likelihood" the Minister could realistically have found that Ms Palmer posed "no", "no non-negligible" or "an extremely low" risk of reoffending by reason of the evidence demonstrating that: (a) since 2016, Ms Palmer had consistently adhered to her treatment plan for HIV to maintain an undetectable viral load, even where she had used illicit drugs; (b) HIV cannot be transmitted from one person to another if the former has an undetectable viral load; and (c) there was nothing to suggest that she would not continue to adhere to her treatment plan going forward.
115 By this ground, Ms Palmer impugns the Minister's findings at MD[77], which are extracted as follows:
I have found that the nature of Ms PALMER's conduct is very serious. I have further found that grievous bodily harm by infecting another with HIV has the potential to cause physical and psychological injury to members of the Australian community and subsequent financial harm to the Australian community as a whole. On balance I consider there to be a low likelihood that Ms PALMER will reoffend. Nevertheless, I considered that, should Ms PALMER engage in similar conduct again it may result in psychological and physical harm to members of the community and subsequent financial harm to the Australian community as a whole. I have given this significant weight towards a finding that it is in the national interest to cancel Ms PALMER's visa.
(Emphasis in original.)
116 Ms Palmer contends that, read in context, the Minister's use of the word "reoffend" (emphasis added) must have referred to Ms Palmer transmitting HIV to another person without their consent, given that was the offence which she had been convicted of and was the focus of the Minister's Decision. In making that finding, the Minister had regard to the following adverse facts: (a) Ms Palmer had used illicit drugs since the Tribunal revoked the cancellation decision (see MD[48], [51], [56]-[59], [63]); (b) prior to commencing treatment in 2016, Ms Palmer was in denial about her HIV diagnosis, took illicit drugs and was reckless in her approach to her own sexual health and the sexual health of her partners (see MD[49], [53], [64]-[65], [73]); (c) Ms Palmer had been convicted of driving offences (see MD[54], [69]-[70]); and (d) Ms Palmer had been inconsistent in her evidence to the Tribunal regarding her remorse (see MD[66], [68]). Ms Palmer submits that there is no rational or logical connection between the preceding adverse facts and a finding that there was a "low likelihood that Ms Palmer will reoffend": see Minister for Immigration and Citizenship v SZMDS [2010] HCA 16; 240 CLR 611 at [131], [135].
117 Ms Palmer submits that the fact remained that on the evidence before the Minister, there was no, or no realistic, prospect of Ms Palmer not taking her HIV medication consistently, even if she were to relapse into illicit drug use. Whilst the Minister noted this evidence (at MD[49]-[50], [52], [62]-[63]), he sought to "explain it away" on the basis that Ms Palmer had used illicit drugs in the past, as demonstrated in the following extracts of the Minister's Decision:
49. … I accept that the potency of the medication provides some protection to the community however I note Ms Palmer and her representative state that in the past Ms Palmer has been so caught up in the drug life that she has behaved negligently and recklessly regarding her own sexual health and the health of others.
…
52. … Mr Coyle states that even if Ms Palmer returns to drug use, to transmit HIV she will have to cease her medication, develop a detectable HIV load and then behave in a manner which transmits HIV. I accept that the risk of the confluence of these events is low however it cannot be discounted in light of Ms Palmer's return to substance use.
53. … I accept that the majority of injecting drug users abide by harm minimisation practices; however I note Ms Palmer does not have a history of engagement in harm minimisation while under the influence of drugs.
…
63. I accept that Ms Palmer's engagement with a rehabilitation program and medical supports reduces the likelihood of Ms Palmer reoffending. Ms Palmer's return to drug use while under parole supervision however is concerning. Ms Palmer's risk of infecting another person with HIV is directly correlated with her medication compliance. In her own submission Ms Palmer states she behaves recklessly or negligently when under the influence of drugs or in order to pay for drugs. I find Ms Palmer's return to drug use increases the likelihood of her reoffending.
118 On Ms Palmer's submission, the above findings do not grapple with the fact that Ms Palmer had consistently taken her HIV medication and maintained an undetectable viral load, even where she had taken illicit drugs. Put another way, the evidence did not support the proposition that the use of illicit drugs increased the risk of HIV transmission. Ms Palmer contends that, in reaching the opposite conclusion, the Minister engaged in irrational, illogical or unreasonable fact-finding.
119 Ms Palmer also submits that, in making the abovementioned findings, it appears that the Minister failed to have regard to the evidence of Ms Palmer in her statutory declaration made on 19 May 2021 (that is, despite having used illicit drugs following her release into the community in January 2020, she did not cease taking her HIV medication). Nowhere under the heading "Remorse and rehabilitation" in the Minister's Decision did the Minister engage with this evidence which, on Ms Palmer's submission, also amounted to error: see Plaintiff M1 at [27]; SZRKT at [111].
120 Another purported error, according to Ms Palmer, is that the Minister misunderstood the evidence of Dr Olga Martinez given before the Tribunal. The relevant part of her evidence was extracted by the Tribunal as follows (at T[105]):
It would be of - it would be of concern if there was evidence that the use of the methamphetamine led to her not being adherent to her antiretroviral medication. I don't know that that would necessarily be the case. I think it's quite possible that if she were to use the methamphetamines from the point of view of the [sic] continuing to take the antiretroviral medication it is quite possible and quite likely I would think that she would continue to take her medications.
Of course there [sic] would be of concern from the point of view of what other effect the methamphetamines may have on her general health but not necessarily be in relation to whether she would continue to adhere to the antiretroviral medications or not.
121 The Minister described Dr Martinez's evidence as follows (at MD[50]):
In her evidence to the AAT, Dr Olga Patricia Martinez stated that if Ms PALMER were to return to methamphetamine use it would be 'of concern' however 'quite likely' and 'quite possible' that Ms PALMER would continue to maintain her antiretroviral treatment Attachment E.
(Emphasis in original.)
122 Ms Palmer contends that, contrary to the Minister's understanding of Dr Martinez's evidence, Dr Martinez did not say that the use of methamphetamines by Ms Palmer was itself "of concern". Rather, the concern was said to arise if the evidence showed that use of methamphetamines would lead to Ms Palmer not adhering to her antiretroviral medication. There was no such evidence before the Minister.
123 Ms Palmer contends that, had any of the foregoing errors not been made by the Minister, it is at least possible that he could have found that Ms Palmer's use of illicit drugs did not increase the likelihood of her reoffending: see MD[63]. The Minister might then have found that there was less than a "low likelihood that Ms Palmer will reoffend" (at MD[77]), such as a "very low" or "negligible" risk. Had the Minister reasoned in this way, Ms Palmer submits that it was at least possible that he might not have placed "significant weight" on Ms Palmer's risk of reoffending "towards a finding that it is in the national interest to cancel [her] visa": at MD[77]. This, in turn, might have caused the Minister not to find that setting aside the Tribunal's decision and cancelling Ms Palmer's visa was in the national interest.
124 For the following reasons, it is my view that the finding that there was a low likelihood of Ms Palmer reoffending was open for the Minister to make. For there to be error Ms Palmer must prove the "high threshold" of "extreme" illogicality or irrationality - that the impugned decision was one at which no rational or logical decision-maker could have arrived on the same evidence: DGPZ v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2022] FCAFC 107; 293 FCR 558 at [75] per Besanko J (Wheelahan and Rofe JJ agreeing), citing Minister for Immigration and Border Protection v MZZMX [2020] FCAFC 175; 280 FCR 1 at [23]-[25]. It is not sufficient for the Court to find that threshold is met even if Ms Palmer, or the Court, emphatically disagrees with the finding: see SZMDS at [124], [129], [132].
125 The gravamen of Ms Palmer's complaint is that the Minister did not consider the unchallenged evidence that Ms Palmer continued to take her HIV medication and maintained an undetectable viral load during relapses into drug use. Had the evidence been considered, Ms Palmer contended that no rational decision-maker could have referred to Ms Palmer's past conduct in the context of her present risk, and found that her return to drug use increased the likelihood of her reoffending.
126 The Minister's finding must be understood in context. The risk to the community finding arises from the Minister's cumulative consideration of factors contributing to past conduct, remorse and rehabilitation. It was open for the Minister to consider Ms Palmer's admissions that she "behaves recklessly or negligently when under the influence of drugs or in order to pay for drugs" (MD [63], see also MD [49]), and has "shown impaired judgement by further unrelated offending" (MD [54]) which increased the likelihood of her reoffending, even if the overall likelihood of her reoffending was low: at MD [77]. The Minister was "sceptical" about certain of Ms Palmer's rehabilitation claims (at MD [57]-[60]), including her return to drug use while under parole supervision (MD [63]). Further, the Minister was circumspect regarding the degree of her remorse: MD [68]. It may be accepted that the fact that Ms Palmer had taken her medication in the past may have assured some decision-makers that there was no possible prospect that that would not continue into the future. The Minister acknowledged the evidence of Dr Martinez, that it was "quite likely" and "quite possible" that Ms Palmer would continue to maintain her antiretroviral treatment (MD [50]). Further the Minister referred to the evidence of Mr Cogle that the risk of a confluence of these events "is low however it cannot be discounted in light of Ms Palmer's return to substance use": at MD [52]. I accept the Minister's submission that it was neither illogical nor irrational in the legal sense for the Minister to reason that the admitted recklessness and negligence as to Ms Palmer's sexual health and the health of others (when using drugs) was a cause of concern, and that there was consequently a low, but not zero, risk of reoffending. I do not accept Ms Palmer's contention was the only rational and logical conclusion that the Minister could have arrived at.
127 With respect to Dr Martinez's evidence as to whether Ms Palmer would continue to take her anti-retroviral medication if she returned to methamphetamine use, as the Minister submitted, the height of Dr Martinez's evidence went was that it was "quite possible" and "quite likely" that Ms Palmer would continue taking her medication if she returned to illicit drug use. Further, Dr Martinez stated that return to methamphetamine use would be concerning in two respects: first, if there was evidence that the use of methamphetamine led to Ms Palmer not being adhered to her medication, and secondly, a more general concern on Ms Palmer's overall health. Given the same, the Minister's summary of Dr Martinez's evidence as extracted at [121] above is both fair and entirely unobjectionable.
128 For these reasons, ground 3 is not made out.
