What this practically means
#Executive summary
#Key legal issues
#Whether the appellant acted in lawful self-defence when he shot the deceased
Yes. Given the crime-prone area, the hours of darkness, and the group advancing while shooting, the appellant was justified in concluding his life was in danger and the trial court erred in ascribing criminal liability for his use of the firearm.
The trial court's unchallenged findings established that the appellant and colleagues were operating in a dangerous crime zone where several officers had been killed or injured, encountered a group emerging from a thicket at about 9 p.m., fired in the air, and were met with gunfire. Applying Section 17 of the Penal Code and the English Common Law principles in Palmer v R, the court held that immediate defensive action was warranted and that a police officer cannot wait until he is struck before striking in self-defence. The conviction for manslaughter could therefore not stand.
Whether the State could seek a conviction for murder and enhancement of sentence on appeal without a cross-appeal
No. Having filed neither a cross-appeal nor a notice of enhancement, the State could not reopen the finding of manslaughter or seek a harsher sentence.
During the hearing, State counsel urged the court to find the appellant guilty of murder and enhance the sentence. The court noted that the trial judge's findings that the death was not an extra-judicial killing and lacked the necessary intention had not been challenged below, and that no cross-appeal or notice of enhancement of sentence was filed. It was therefore too late in the day to reopen the contention or vary the sentence, and the unchallenged findings bound the appellate court's frame of inquiry.
The duty of a first appellate court
A first appellate court must subject the whole evidence to a fresh and exhaustive examination and reach its own conclusions, not merely check whether some evidence supports the lower court's findings.
Relying on Okeno v Republic, the court restated that an appellant on a first appeal is entitled to a fresh and exhaustive examination of the evidence and to the appellate court's own decision on the evidence, weighing conflicting evidence and drawing its own conclusions while making allowance for the trial court's advantage of having seen and heard the witnesses. The court then applied that mandate to the two competing versions of how the deceased met his death.
Legal principles established
#- A first appellate court must re-evaluate the evidence afresh, weigh conflicting evidence and draw its own conclusions, making allowance for the trial court's advantage of seeing and hearing the witnesses.
- A person, including a police officer, who is attacked may use such force as is reasonably necessary in self-defence; whether force was reasonable depends on the facts, including the seriousness and immediacy of the peril.
- In circumstances of a violent confrontation at night in a known crime zone, a police officer may reasonably believe his life is in danger and open fire; he need not wait until he is struck before striking in self-defence.
- An appellate court cannot entertain a request for enhancement of sentence where the State has filed no cross-appeal or notice of enhancement.
- Criminal responsibility for the use of force in defence of person or property is determined according to the principles of English Common Law as imported by Section 17 of the Penal Code.
