Holding

The Supreme Court dismissed the appeal against a manslaughter conviction. It held that the trial judge wrongly treated a concession by defence counsel in submissions as an admission by the appellant; counsel's concession cannot be equated with the accused's own admission. However, although the sole eyewitness was a child of tender years whose evidence required the judge to warn herself and the assessors of the danger of acting on it uncorroborated, the appellant's conduct in fleeing and hiding after cutting the deceased amounted to corroboration. The defence of insanity was properly excluded on expert evidence. The misdirection did not vitiate the conviction because the judge considered all the evidence and reached the correct conclusion.

Facts

The appellant, a porter, and the deceased, a 13-year-old boy, lived in a camp at Nakalesa Tea Estate, Mukono District. On 22 November 1994 at about 5.00 p.m. the deceased and other children were playing near the appellant's residence. The appellant came out armed with a small wood-carving axe, announced that he was mad, cut the deceased on the forehead with the axe, and ran away. PW6, a child aged between six and eight at the time, witnessed the attack and raised the alarm. The deceased was taken to Kawolo Hospital, where he died the following day. The appellant was traced and arrested. He denied the offence and raised defences of insanity and intoxication, relying on a history of mental disturbance and hospitalisation at Butabika in 1985. Expert evidence (DW2, the Director of Butabika Hospital) indicated the appellant had been treated for three months in 1985 and that a person with his persecutory-type disorder would not go into hiding immediately after committing an offence. The trial judge convicted of manslaughter rather than murder, accepting a possibility of intoxication.

Issues

  1. Whether the trial judge misdirected herself by holding that the appellant had admitted killing the deceased on the basis of a concession made by his counsel in submissions.
  2. Whether the conviction could stand where it rested on the uncorroborated evidence of a child of tender years and the judge had not warned herself and the assessors of the danger of so doing.
  3. Whether the trial judge erred in excluding the defence of insanity.

Orders

  • Appeal against conviction and sentence dismissed.

Key headnotes

Evidence — Child of Tender Years — Corroboration Warning
The requirement that a trial judge warn himself and the assessors of the danger of acting on the uncorroborated evidence of a child of tender years, though a rule of practice rather than a rule of law, has acquired the force of law, and failure to give the warning will normally vitiate the conviction.
Evidence — Corroboration — Conduct of the Accused as Corroboration
The conduct of an accused in fleeing the scene and hiding himself after the act amounts to corroboration of the evidence of a child of tender years, even where the trial judge does not expressly characterise it as such.
Criminal Procedure — Admissions — Concession by Defence Counsel
A trial judge is not entitled in a criminal trial to treat a concession made by defence counsel in submissions as an admission by the accused; counsel's concession cannot be equated with the accused's own admission of the offence.
Criminal Law — Defence of Insanity — Reliance on Expert Evidence
Where expert evidence excludes the probability that the accused was insane at the material time, the trial judge is entitled to rule out the defence of insanity after directing herself and the assessors upon it.
Criminal Appeal — Effect of Misdirection — Proviso
A misdirection by the trial judge on the evidence does not vitiate a conviction where the judge nonetheless considered all the available evidence and defences and arrived at the correct conclusion on the facts.
