De Zoysa v R.

Factual and Procedural Background

On 25 September 2020, the applicant was stopped by police in Norbury carrying a brown bag containing cannabis, live ammunition, and a loaded antique revolver concealed under his left armpit. He was arrested and handcuffed. While left alone in a police van, he retrieved the gun. Shortly after being taken to a holding cell at a police station, he produced the gun and shot the custody sergeant twice at close range, causing fatal injuries. The applicant was shot and severely injured by police during the incident, resulting in a stroke and permanent brain damage, leaving him with significant communication and physical impairments.

The applicant, diagnosed with autism spectrum disorder in childhood and with no previous convictions, was charged with murder and related firearms offences. After a fitness to plead hearing in November 2022, he was found fit to stand trial. The trial took place over two weeks in June 2023, resulting in a unanimous conviction for murder and a whole life sentence imposed in July 2023. Applications for leave to appeal conviction and sentence were refused by the single judge and renewed before the full court, which also refused them. This opinion provides the reasons for those refusals.

Legal Issues Presented

1. Whether the trial judge erred in finding the applicant fit to plead and stand trial, particularly in light of the introduction of a partial defence of diminished responsibility based on an autistic meltdown.
2. Whether the trial judge erred in refusing the defence application for the jury to view the holding cell where the shooting occurred.
3. Whether the trial judge failed to properly direct the jury on considering autism in relation to the unlawful act manslaughter alternative verdict.
4. Whether the sentence imposing a whole life order was wrong in principle or manifestly excessive given the applicant's background and circumstances.

Arguments of the Parties

Appellant's Arguments

• The applicant challenged the fitness to plead determination, arguing that the introduction of diminished responsibility based on an autistic meltdown complicated the legal issues beyond his capacity to understand and participate fairly in the trial.
• The defence sought a jury site visit to the holding cell, contending it was necessary to support the applicant's restricted ability to express himself and to assist the jury's understanding.
• The defence argued that jury directions on manslaughter should be adapted to consider the applicant's autism, suggesting the substantive law should be amended accordingly.
• Regarding sentence, it was submitted that a whole life order was unjustified due to mitigating factors including the applicant's difficult upbringing, autism, injuries sustained, and the impact of custody on him and his family.

Respondent's Arguments

• The prosecution maintained that the applicant was fit to plead and stand trial, supported by expert psychiatric evidence and the trial judge's comprehensive assessment and adaptations made to ensure a fair trial.
• The respondent opposed the jury site visit, arguing no material benefit would arise, and that subjective impressions of the holding cell were irrelevant and potentially distressing.
• The prosecution submitted that the law on unlawful act manslaughter was settled and could not be altered by the court to accommodate neurodiversity; any change would be a matter for Parliament.
• The respondent asserted that the whole life order was appropriate given the exceptional seriousness of the offence, including the murder of a police officer on duty, and that the judge properly considered mitigating factors.

Table of Precedents Cited

Precedent	Rule or Principle Cited For	Application by the Court
R v Pritchard (1836) 7 C&P 303	Establishes six criteria for assessing fitness to plead and stand trial, including understanding charges, deciding plea, instructing counsel, following proceedings, challenging jurors, and giving evidence.	The court applied the Pritchard criteria to assess the applicant's fitness, confirming the trial judge's findings that despite disabilities, the applicant met the required capabilities with appropriate adaptations.
R v John M [2003] EWCA Crim 3452	Refinement of the Pritchard test for fitness to plead.	Used to support the framework for assessing the applicant's fitness in the context of his disabilities and trial circumstances.
R v Marcantio; R v Chitolie [2016] EWCA Crim 14; [2016] 2 Cr.App.R. 9	Further refinement and application of the Pritchard criteria in fitness to plead assessments.	Reinforced the approach taken by the trial judge and the court in evaluating the applicant's fitness to plead, including consideration of adaptations.
R v Nica [2021] EWCA Crim 1719	Confirms that changes to substantive criminal law, such as adapting the test for unlawful act manslaughter, are matters for Parliament, not the courts.	The court relied on this precedent to reject the defence submission to adapt the law on manslaughter to account for autism, affirming the judge's correct application of settled law.
R v Stewart [2023] 1 Cr App R (S) 17	Guidance on sentencing, including assessment of seriousness and whether a whole life order is appropriate.	The court found the sentencing judge correctly applied Stewart's principles, thoroughly reviewing relevant factors and properly concluding the exceptional seriousness warranted a whole life order.

Court's Reasoning and Analysis

The court undertook a detailed review of the trial judge's findings on the applicant's fitness to plead, emphasizing the limited and straightforward nature of the trial issues and the extensive procedural adaptations made to accommodate the applicant's communication and cognitive difficulties. The Pritchard criteria were applied contextually, with recognition that full understanding of complex legal concepts, such as diminished responsibility, is not required for fitness to plead.

The court rejected the argument that the introduction of diminished responsibility altered the fitness assessment, noting that the trial judge had carefully considered expert evidence and the applicant's capabilities, including his ability to understand and participate with the assistance of an intermediary and simplified procedures.

Regarding the refusal of a jury site visit, the court found no material benefit to the defence or the jury’s understanding that would outweigh the disruption, cost, and potential distress. The judge's balancing of the overriding objective was proper and not flawed.

On the issue of jury directions concerning autism in unlawful act manslaughter, the court reaffirmed that substantive legal principles cannot be modified by the judiciary to accommodate neurodiversity; such changes are for Parliament. The jury's conviction for murder rendered the manslaughter direction issue moot.

In sentencing, the court upheld the whole life order, agreeing with the trial judge's assessment of exceptional seriousness due to the murder of a police officer on duty and the aggravating factors such as premeditation and risk to others. The judge properly considered mitigating factors including the applicant's autism and injuries but found them insufficient to justify a lesser sentence. The court endorsed the judge's thorough application of sentencing guidance.

Holding and Implications

The court REFUSED LEAVE TO APPEAL against both conviction and sentence.

The refusal confirms the trial judge's fitness to plead assessment and the procedural adaptations as appropriate and effective. The rejection of the site visit application and the affirmation of the settled law on manslaughter preserve established procedural and substantive legal standards. The imposition of a whole life order underscores the judiciary's recognition of the exceptional seriousness of the murder of a police officer on duty, with no mitigation sufficient to reduce the sentence.

No new legal precedent was established; the decision reinforces existing principles on fitness to plead, trial procedure, jury directions, and sentencing in serious offences involving defendants with neurodiverse conditions.
