Last week, Justice Mander of New Zealand’s High Court sentenced the Christchurch mosque shooter to life imprisonment without the possibility of parole for the murder of 51 people, attempted murder of 40 others, and terrorism. This punishment is provided for by section 103(2A) of New Zealand’s Sentencing Act 2002.
Justice Mander’s sentencing remarks in R v Tarrant,  NZHC 2192hold some lessons for Canadians, as the Québec Court of Appeal is considering the appeals of both the Crown and the accused from the sentence the Superior Court imposed on the Québec mosque shooter in R v Bissonnette, 2019 QCCS 354. In that decision, about which Maxime St-Hilaire and I wrote here, Justice Huot found the possibility of stacking parole ineligibility periods for multiple murders in a way that amounted to sentencing those who commit them to life imprisonment without parole to a cruel and unusual punishment and a deprivation of liberty contrary to principles of fundamental justice, contrary to sections 7 and 12 of the Canadian Charter of Rights and Freedoms.
Although stating that “the needs of denunciation, of setting an example, and of incapacitation” are especially “pressing” [766; translation mine], Justice Huot went on to find that life imprisonment without a realistic prospect of parole was contrary to Canadian values. Canada, he wrote, “is not a land where the most undesirable elements of the community are shut in a gaol and their very existence forgotten, the key of their liberty having been thrown into the river of a vast collective indifference.” [845; tanslation Professor St-Hilaire’s and mine] For him, the possibility of rehabilitation, even for the worst offenders, means that it is “sophistry to assert that [multiple murderers] should reasonably expect, in a free, civilized, and democratic society, to spend the rest of their days behind bars”.  Justice Mander’s cogent remarks help show that this was wrong.
Justice Mander, it worth noting, is by no means insensitive to considerations of humanity and anti-populism that apparently influenced Justice Huot so much. He considers the prospects of rehabilitation, and notes that “[t]he sentence [he] impose[s] must represent a civilised reaction based not on emotion but justice and deliberation”.  But these concerns are not dispositive in a case such as this.
Addressing Mr. Tarrant, Justice Mander explains that his
prime objectives are threefold. First and foremost, to condemn your crimes and to denounce your actions. Second, to hold you accountable for the terrible harm you have caused — in plain terms, to attempt to impose some commensurate punishment … on behalf of the whole community, which in particular includes the victims of your crimes and their families, all of whom are a part of New Zealand’s multicultural society. Third … to protect the community from a person capable of committing cold-blooded murder on such a scale and who presents such a grave risk to public safety. 
Justice Mander notes that section 9 of New Zealand bill of Rights Act 1990 prohibits the imposition of “disproportionately severe … punishment” (judicially interpreted as calling for a test of gross disproportionality ― similar to the one applied to test the constitutionality of legislation under section 12 of the Canadian Charter of Rights and Freedoms). He notes, also, that “[t]here is European jurisprudence that indicates the imposition of a whole-of-life sentence in the absence of any effective review mechanism is incompatible with
international human rights instruments”.  Nevertheless, he finds that nothing short of a life sentence without parole would be proportionate to the crimes here.
Let me quote just one paragraph about the facts (this one drawn from Justice Mander’s discussion of the aggravating circumstances). It is horrible, and there is, alas, so much more horror in this case ― as there was in the Bissonnette one:
It is self-evident that your offending constituted extreme violence. It was brutal and beyond callous — your actions were inhuman. You deliberately killed a threeyear-old infant by shooting him in the head as he clung to the leg of his father. The terror you inflicted in the last few minutes of that small child’s life is but one instance of the pitiless cruelty that you exhibited throughout. There are countless more examples. You showed no mercy. 
In Justice Mander’s view,
no minimum period of imprisonment would be sufficient to satisfy the legitimate need to hold you to account for the harm you have done to the community. Nor [would] minimum term of imprisonment would be sufficient to denounce your crimes. 
Indeed, in a comment particularly relevant to the comparison the sentence he imposes with Justice Huot’s preoccupation with not letting people spend their lives behind bars, Justice Mander observes that, were he “to impose a minimum period of imprisonment in an endeavour to meet the purposes that I am required to achieve in sentencing you for murdering 51 people, it could not be less than [Mr. Tarrant’s] natural life”.  Ultimately, he does
not consider, however long the length of your incarceration during your lifetime, that it could, even in a modest way, atone for what you have done. Ordinarily such an approach would be a poor guarantee of just and proportionate punishment, but I consider yours is one of those exceedingly rare cases which is different. 
I think that Justice Mander is right about all of this. Justice Huot, who would no doubt hurl accusations of “sophistry”, populism, and other assorted sins, would not only be wrong but, at the risk of sounding pompous, morally obtuse. Collective indifference and forgetfulness are not just, or even primarily, concerns in relation to those who commit terrible crimes. It would be no less ― and indeed much more ― wrong to be indifferent to the crimes themselves. And it will still be wrong decades from now.
As I recently wrote in discussing an Alberta judgment on the application of section 12 of the Charter, I think that the gross disproportionality test is a sensible construction of its “cruel and unusual punishment” prong, so far as individuals (rather than legal persons) are concerned. Well, I don’t think there is anything grossly disproportional, or indeed disproportional in any way, in denying the possibility of parole to a man who presents himself to a place of worship with the sole purpose of killing as many people as possible, and proceeds to do just that. On the contrary, I think justice may well demand no less. Perhaps there are policy considerations that would explain why a legislature might not put that option on the table. But at the level of principle, I think the New Zealand approach of making the life without parole sentence available in cases where the objectives of punishment cannot be met by a lesser one is right. The Canadian approach of making the parole non-eligibility terms of multiple murderers run consecutively amounts to the same thing, but less transparently, so I think the New Zealand one is preferable.
Granted, the sentencing court should consider repentance and the prospect, even if unlikely on balance, of rehabilitation. There seems to be a difference on this point between the Québec and Christchurch cases, and if this were the reason for Justice Huot’s decision not to impose, in effect, a life sentence without parole, it might have been defensible. (I’m not sure it would have been. Luckily I’m not a judge in charge of sentencing mass murderers, so I get to punt on this question.) But that’s not the main consideration that motivated Justice Huot. On the contrary, he felt strongly enough the need to denounce and punish Mr. Bissonnette that he rewrote (which is a nice way of saying “broke”) the law to impose a 40-year parole ineligibility period, instead of a 25-year one. That suggests that, ultimately, he thought that, as in the Christchurch case, punishment and denunciation dominate. And, if so, a sentence without parole is warranted.
I fully agree with Justices Huot and Mander that the measure of just punishment is not its ability to grab the headlines, and that a civilized justice system must move away from the “an-eye-for-an-eye” instinct. Cases such as these remind us, in any event, the futility of such fantasies. Even if we were in the business of killing murders, we couldn’t kill them six, or fifty-one, times over.
But Justice Mander’s sentencing remarks are a reminder that one need not be vengeful, or to simple-mindedly parrot the tough-on-crime line, to find, in truly shocking and exceptional cases, that the most severe punishment is warranted. Protecting the lives of the citizens is the state’s first responsibility on any plausible view of its role. Providing justice, in the form punishment, in response to those who take their fellow human beings’ lives is the second. In the face of contempt for human life and indifference to, if not actual pleasure in, human suffering, retribution is called for. In extreme cases, locking such people up and throwing away the key is only fair. I do hope that the Québec Court of Appeal, and the Supreme Court if comes to that, take note.
