Holding

The Court of Appeal dismissed the 2nd appellant's challenge to conviction, holding that the trial judge properly admitted the appellants' voluntary extra-judicial confessions, corroborated by identifying witness PW2 and the post-mortem reports, and correctly found participation through common intention; the circumstantial evidence left no co-existing innocent inference. Ground 1 failed and the convictions for murder and aggravated robbery stood. On sentence, the Court agreed the original 38-year and 20-year terms were illegal because the trial judge failed to make the arithmetical deduction of the remand period required by Article 23(8). Stepping into the trial court's shoes, it re-sentenced both appellants, deducting 3 years 9 months 14 days spent on remand.

Facts

On 10 October 2013 at Kihuna village the appellants, acting with others, attacked John Bosco Tumwesigye at gunpoint and stole Shs. 700,000, then a further Shs. 100,000 from his shop, where they shot his wife Annet Busingye, who was heavily pregnant. They stole a further Shs. 400,000 from others and shot John Bosco Magezi, a 13-year-old boy, dead. The gun used had earlier been stolen from Kakindo Police Post, an offence for which the 1st appellant had been separately convicted. PW2, Besige Joseph, was attacked during the events; during a roughly 30-minute scuffle under bulb light he removed the 1st appellant's mask and identified both appellants, later picking them at an identification parade. Both appellants made extra-judicial confessions implicating each other; the 1st appellant admitted the 2nd appellant shot Annet Busingye, while the 1st appellant shot Magezi. Post-mortem reports confirmed both deceased died of gunshot wounds. The appellants were convicted on two counts of murder and two counts of aggravated robbery and sentenced.

Issues

  1. Whether the trial judge erred in relying on circumstantial evidence containing inconsistencies to convict the appellants.
  2. Whether the appellants' extra-judicial confessions were voluntarily made and properly admitted in evidence.
  3. Whether the 2nd appellant participated in the murders and aggravated robberies, including by common intention.
  4. Whether the sentences were manifestly harsh and excessive and illegal for failure to make an arithmetical deduction of the remand period under Article 23(8) of the Constitution.

Key headnotes

Evidence — Confessions — Confession by co-accused — Admissibility against another jointly tried (Evidence Act s.28, now s.27)
Where persons are tried jointly for the same offence, a confession by one that affects himself and a co-accused may be taken into consideration against that co-accused as well as against the maker.
Evidence — Confessions — Voluntariness — Trial within a trial
Where the voluntariness of a confession is challenged, the court must conduct a trial within a trial; a confession recorded after caution, in a language the accused understands, read back to him, and given without injury or duress, is properly admitted as voluntary.
Criminal Law — Common intention — Inference of participation (Penal Code Act s.20)
Where two or more persons form a common intention to prosecute an unlawful purpose and an offence is committed as a probable consequence, each is deemed to have committed it; common intention may be inferred from presence at the scene, conduct, and failure to disassociate from the crime.
Evidence — Circumstantial evidence — Inference of guilt — Exclusion of co-existing circumstances
Before drawing an inference of guilt from circumstantial evidence, the court must narrowly examine it and be satisfied that there are no co-existing circumstances which would weaken or destroy the inference of guilt.
Criminal Law — Aggravated robbery — Deadly weapon — Firearm discharged during robbery
Once a gun is fired in the course of a robbery it is deemed to be a deadly weapon for the purposes of aggravated robbery.
Criminal Procedure — Sentencing — Remand period — Article 23(8) of the Constitution
Taking the period spent on remand into account under Article 23(8) of the Constitution requires an arithmetical deduction of that period from the final sentence; a failure to make that deduction renders the sentence illegal.
Criminal Procedure — Appellate sentencing — Power to interfere and re-sentence
A first appellate court re-evaluates the evidence and will not interfere with sentence unless it is illegal or manifestly excessive so as to amount to injustice; where the sentence is illegal the court may step into the trial court's shoes and re-sentence.
