Summary
The statutory defence of provocation has subjective and objective elements. The jury assesses whether the accused lost self-control and whether the provocation was sufficient for a person with ordinary self-control to react in the same or a similar way. There is no legal requirement that the mode, weapon or ferocity of the killing be proportionate to the provocation. Those matters remain relevant considerations in the objective evaluation. A direction requiring exact correspondence between the reasonable person’s conduct and the accused’s conduct is a misdirection. It may nevertheless be cured by the appellate proviso where no reasonable jury could accept provocation and no substantial miscarriage occurred. Fresh evidence of diminished responsibility must satisfy sequential credibility, freshness and safety tests, applied in the interests of justice.
Factual background
The appellant was convicted of murder after a jury trial in Trinidad and Tobago. The Court of Appeal dismissed his appeal against conviction and sentence in 2017. A later application relied on fresh psychiatric evidence and challenged the trial direction on provocation. Permission to appeal was granted on those two grounds, but refused on fitness to plead.
The central issues were whether Offences Against the Person Act section 4B required the jury to consider whether an ordinary person would have killed in precisely the same manner, and whether fresh evidence could support diminished responsibility under section 4A and should be admitted on appeal.
Held
Provocation. The Board held that the trial judge had materially misdirected the jury by repeatedly asking whether a reasonable person would have done exactly what the appellant did, including inflicting the precise injuries. The correct approach under section 4B requires consideration of the gravity of the provocation and the ordinary powers of self-control expected in society.
- There is no rule of law requiring the mode of killing, weapon used or ferocity of the attack to bear a proportionate relationship to the provocation. Those matters remain relevant factors which the jury may consider in applying the objective test.
- The words “do as he did” do not require exact correspondence. A reasonable person might have acted in the same or a similar way. The question is whether it was reasonable to lose self-control to the degree shown by the accused.
- The approach in Marcelline v The State Crim App No S015 of 2014, adopting the contrary reasoning in HKSAR v Liang Yaoqiang (No 2) [2017] HKCU 289, should no longer be followed on this point. The strict formulation in Phillips v The Queen [1969] 2 AC 130 was also too exacting.
Although the direction was defective, the proviso in section 44(1) applied. The evidence demonstrated premeditation, and no reasonable jury could accept provocation. There had therefore been no substantial miscarriage of justice on that ground.
Fresh evidence and diminished responsibility. Section 47 gives the appellate court power to receive evidence where necessary or expedient in the interests of justice. The sequential approach in Lundy v The Queen [2013] UKPC 28 was applied. The expert evidence was capable of belief, its absence at trial was not disputed on due diligence grounds, and it might affect the safety of the conviction. Section 4A(1) requires abnormality of mind and substantial impairment of mental responsibility. The case was remitted to the Court of Appeal to determine the admissibility and effect of the evidence, and the Board invited guidance for routine mental-state assessments in suitable future cases.
