Holding

The Court of Appeal allowed the appeal against a murder conviction, holding that the prosecution's own evidence — including the psychiatric report showing the appellant suffered paranoid delusions and hallucinations — established that he was insane at the time of the offence within section 11 of the Penal Code Act. The trial judge erred by treating knowledge that he was killing a person as the test, rather than whether he knew he ought not to do the act. The court found section 194 of the Penal Code Act (diminished responsibility) inapplicable and held section 48(1) of the Trial on Indictment Act required a special finding. The conviction and life sentence were set aside and a special finding of not guilty by reason of insanity substituted.

Outcome

Conviction for murder set aside; special finding of not guilty by reason of insanity entered; appellant to remain in custody pending evaluation of mental condition and report to the Minister

Facts

The appellant lived with his three-year-old son, Moses Tirwomwe, in Kabale District. On 21 June 2011 around 10 am, the appellant hacked the deceased on the head with a panga and burned the body on a pile of firewood. Neighbours found the appellant lying near the burnt body; when asked what had happened, he said he had killed and burned an evil spirit or beast that used to torment him at night. He was arrested immediately, charged, tried and convicted of murder, and sentenced to life imprisonment. A psychiatric officer (PW4) who examined the appellant shortly after arrest reported that he was mentally disordered due to substance abuse, presenting with paranoid and persecutory delusions and visual and auditory hallucinations including voices commanding him to kill his child. PW4 opined that despite the substance influence the appellant knew he was killing a person. The trial judge relied on this to convict, treating the substance-induced condition as not excluding responsibility.

Issues

  1. Whether the trial judge erred in law in failing to make a special finding of not guilty by reason of insanity under section 48(1) of the Trial on Indictment Act.
  2. Whether the prosecution evidence established that the appellant was insane at the time of commission of the offence so as not to be criminally responsible under section 11 of the Penal Code Act.
  3. Whether the burden of proving insanity, and the applicability of section 194(2) of the Penal Code Act, were correctly applied.

Orders

  • Ground 1 of the appeal allowed.
  • Conviction of the appellant for murder set aside.
  • Special finding made under section 48(1) of the Trial on Indictment Act that the appellant was not guilty by reason of insanity at the time of commission of the offence.
  • Case to be reported to the Minister under section 48(2) of the Trial on Indictment Act.
  • Appellant to be kept in custody by the prisons authorities pending evaluation of his mental condition and report to the Minister.

Rules and key headnotes

Defence of Insanity — Test under Section 11 Penal Code Act — Capacity to Know the Act Was Wrong
The test for the defence of insanity under section 11 of the Penal Code Act is not merely whether the accused knew he was killing a person, but whether, through a disease affecting his mind, he was incapable of understanding what he was doing or of knowing that he ought not to do the act; knowledge that one is killing a person does not answer the question of responsibility.
Defence of Insanity — Special Finding under Section 48(1) Trial on Indictment Act
Where evidence given at trial, whether adduced by the prosecution or the defence, shows that the accused was insane so as not to be responsible for his action at the time of the offence, the court must make a special finding under section 48(1) of the Trial on Indictment Act that the accused is not guilty by reason of insanity.
Insanity — Source of Evidence — Prosecution Evidence May Establish Insanity
The state of mind of the accused may be discerned from evidence on record adduced by either party; where the prosecution's own evidence establishes that the accused was insane at the time of the offence, that evidence may found a conclusion of insanity and there is no need to put the accused to his defence on the point.
Diminished Responsibility — Section 194 Penal Code Act — Distinction from Insanity
Section 194 of the Penal Code Act, dealing with diminished responsibility, applies only where the accused would otherwise be found guilty of murder and requires the defence to prove abnormality of mind; it is inapplicable where the issue is whether the accused was criminally responsible at all by reason of insanity under section 11, which excuses crime entirely.
Intoxication and Insanity — Section 12 Penal Code Act — Substance-Induced Insanity
A state of insanity produced by intoxication from narcotics or drugs may constitute a defence under the Penal Code Act; the key element remains the fact of insanity, and hallucinations induced by substance abuse may render an accused incapable of understanding what he is doing.
Appellate Reappraisal of Evidence — Rule 30(1) Judicature (Court of Appeal Rules) Directions
On a first appeal from the High Court in the exercise of its original jurisdiction, the Court of Appeal must reconsider and re-evaluate the evidence, drawing its own inferences of fact, while making due allowance for the fact that it did not see or hear the witnesses.
