Holding

The Court of Appeal quashed the appellant's conviction for murder and aggravated robbery. The conviction rested on circumstantial evidence — sniffer dog behaviour, a bloodstained grey trouser, and a quarry stone. The court held that sniffer dog evidence was improperly admitted because the dog's experience, skill and training were not established, and the scent's integrity was not proved. It found there were other plausible hypotheses, namely that the appellant was at the scene only after the crime, which weakened or destroyed any inference of guilt. The circumstantial evidence did not exclude every reasonable hypothesis other than guilt, so the appellant was entitled to the benefit of the doubt. Conviction quashed and sentence set aside.

Outcome

Conviction quashed, sentence set aside, and appellant ordered set free forthwith unless lawfully held on other charges

Facts

On 10 June 2013 at Kanyamunyu cell, Kasese district, Biira Teddy was attacked at night, robbed of UGX 1,600,000 and a mobile phone, and killed with a gun. No witness saw the assailants. The deceased's daughter (PW1) heard the attackers but did not recognise their voices, though she could identify the appellant's voice. The next day after midday a police sniffer dog was introduced to the scene; between the deceased's and appellant's homes were three houses, but the dog went to the appellant's house. A grey bloodstained trouser was allegedly recovered from the appellant's home, and a quarry stone was linked to the entry stone. The appellant testified he answered the alarm after the attack, helped carry the deceased to a vehicle, and was at the vigil before going home for a sweater. The trial court convicted him on circumstantial evidence and acquitted his co-accused. The assessors had advised acquittal of both accused.

Issues

  1. Whether there was sufficient circumstantial evidence to irresistibly incriminate the appellant in the murder and aggravated robbery for which he was convicted.
  2. Whether the trial court properly admitted and relied on the evidence of the police sniffer dog.

Orders

  • Conviction quashed.
  • Sentence of imprisonment imposed on the appellant set aside.
  • Appellant to be set free forthwith unless held on other lawful charges.

Rules and key headnotes

Circumstantial Evidence — Inference of Guilt — Exclusion of Other Reasonable Hypotheses
A conviction based exclusively on circumstantial evidence can only stand where the inculpatory facts are incompatible with the innocence of the accused and incapable of explanation upon any other reasonable hypothesis than guilt, and where no co-existing circumstances exist that would weaken or destroy the inference of guilt.
Sniffer Dog Evidence — Threshold for Admissibility
Before sniffer dog tracking evidence may be admitted, the prosecution must establish the training and experience of the dog handler, and the nature, skill and performance of the particular dog with regard to the specialised task, including its experience in similar tracking cases; failure to establish these credentials renders the threshold for admissibility unmet.
Sniffer Dog Evidence — Caution and Preservation of Scene
Sniffer dog evidence must be treated with utmost caution; the integrity of the scent must be shown not to have been tampered with and the trail must not have become stale, and where the scene was contaminated or the dog's conclusions are inconclusive the evidence cannot conclusively place an accused at the scene at the time of the offence.
First Appeal — Duty of First Appellate Court
A first appellate court has a duty to reappraise the evidence afresh and draw its own inferences of fact, while bearing in mind that it neither saw nor heard the witnesses and making due allowance in that respect.
Benefit of the Doubt — Proof Beyond Reasonable Doubt
Where the circumstantial evidence relied upon admits of other plausible hypotheses consistent with innocence, the accused is entitled to the benefit of the doubt and a conviction founded on such evidence cannot be sustained.
