The bottom line

#

Kenya's Court of Appeal confirmed that possession of a murder weapon soon after the killing, with no credible alibi, can justify a murder conviction on circumstantial evidence alone.

What this practically means

#

Executive summary

#
This was a first and final appeal to the Court of Appeal at Mombasa (Omolo, Waki and Nyamu, JJ.A) against convictions for the murder of John Kamau Muhika, who was shot dead outside his Taveta residence in April 2002. The appellants, Peter Mote Obero and Gideon Kamau Mburu, were arrested the day after the murder at Holili, Tanzania, in possession of a briefcase containing a sawn-off Simonov rifle; ballistics evidence established that the rifle fired the recovered scene cartridges and the killer bullet. The trial judge (Mwera, J.) rejected the victim's widow's visual identification as unsafe but convicted on circumstantial evidence, acquitting a third accused. On appeal, counsel for the appellants argued that the trial court improperly dwelt on the weakness of the defence alibi rather than the strength of the prosecution case, that conviction rested on uncorroborated evidence of a single witness, and that the firearms examiner's opinion went beyond the proper scope of expert evidence, citing Rajabu v Republic. The Court of Appeal rejected all grounds. It held that a single credible witness suffices under section 143 of the Evidence Act; that while ballistics experts ordinarily cannot positively identify the gun that fired a bullet, the unique markings from the sawn-off barrel and the one-day interval between murder and recovery distinguished Rajabu; and that expert opinion may only be rejected on a proper and cogent basis as per Dhalay v Republic. Applying the Teper safeguards, the court found the recent possession of the murder weapon irresistible circumstantial evidence. The appeal was dismissed in its entirety; the death sentences had previously been commuted to life imprisonment by the President.

Questions the Court framed

#

The issues the Court set itself to decide, in its own words.

  1. 1.Whether the trial judge erred by concentrating on the poverty of the appellants' explanation for their presence in the house at Holili rather than on the strength of the prosecution case, and by treating the possession of the gun as proved
  2. 2.Whether the trial judge misdirected himself in convicting on circumstantial evidence resting on a single witness without corroboration
  3. 3.Whether the trial judge erred in relying on the firearms examiner's report which was framed in an incriminating way
  4. 4.Whether the ballistics expert's opinion went beyond the proper scope of expert opinion evidence, in light of Rajabu v Republic, and whether there was a proper and cogent basis to reject it
  5. 5.Whether the circumstantial evidence established that the only reasonable inference was that the appellants, with common unlawful purpose, fired the weapon that killed the deceased

Key legal issues

#
01

Whether the trial court erred in relying on the evidence of a single witness (Cpl George) on possession of the gun

Holding

The ground failed. Possession was a question of fact turning on the credibility of the single witness, who was believed by the trial court; section 143 of the Evidence Act requires no particular number of witnesses.

Reasoning

The court held that joint possession of the gun was a factual issue dependent on the credibility of the one witness who testified to the arrest and recovery. The trial court, which saw and heard him, found him truthful and there was no good reason to declare him untruthful. The finding of possession was one link in the chain of circumstantial evidence and the appellants' alibi was displaced by it.

p. 6
02

Whether the ballistics expert could express a positive opinion that the killer bullet was fired from the gun found with the appellants

Holding

Ordinarily no, but on the facts (a sawn-off rifle producing unique markings, examined within a day) the expert could express a highly positive opinion, which could only be rejected on a proper and cogent basis; Rajabu was distinguished.

Reasoning

The court accepted the textbook learning and Rajabu that positive ballistics identification is generally unjustified. However, the sawn-off rifle gave unique markings to fired ammunition, making identification easier, and the examination followed the recovery within about a day, unlike the three-month lapse in Rajabu. The expert was a long-serving examiner, and no reasonable basis for rejecting his opinion existed.

p. 8
03

Whether the circumstantial evidence established guilt beyond reasonable doubt

Holding

Yes. With the safeguards of Teper satisfied, the possession of the killer gun hours after the murder and near the scene led to the irresistible inference that the appellants committed the offence with common unlawful purpose.

Reasoning

The court weighed the short interval between murder and recovery of the weapon, the proximity to the scene, the appellants' bare denial of possession despite credible direct evidence of recovery, and their unsupportable alibi. The inculpatory facts were incompatible with innocence and no co-existing circumstance weakened the inference; circumstantial evidence is as good as direct evidence.

p. 9

Legal principles established

#
  • A single witness's evidence is sufficient to prove a fact; no particular number of witnesses is required
  • Ordinarily there is no scientific basis for a ballistics expert to state with certainty that a particular bullet or cartridge was fired from a particular gun; expert opinion is not binding and can only be rejected on a proper and cogent basis
  • Circumstantial evidence justifying an inference of guilt must be incompatible with the innocence of the accused and incapable of explanation on any other reasonable hypothesis, and no co-existing circumstances may weaken or destroy the inference
  • Possession of an article directly connected with a crime, shortly after its commission, may lead to the irresistible inference that the possessor participated in the crime
  • An alibi need not be proved by the accused, but it may be displaced by other evidence
  • On a first appeal the Court of Appeal must re-evaluate and re-examine the entire evidence while allowing for the trial court's superior position on credibility

Court orders

Jurisdiction invoked
First and final appeal to the Court of Appeal against conviction and sentence for murder under the Criminal Procedure Code (appeal as of right from the High Court on a first appeal)

Relief refused

#

Quashing of the convictions and death sentences (subsequently commuted to life imprisonment)

The court found the circumstantial evidence complete: possession of the killer gun shortly after the murder, near the scene, with an alibi that did not weaken or destroy the inference of guilt

Costs

No costs order was made in the judgment (criminal appeal; judgment silent on costs)

Quotable passages

#

Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.

We reject their appeal in totality and order that it be and is hereby dismissed.
p. 9Final orders - dismissal of appeal
It is the essence of circumstantial evidence that, in order to justify an inference of guilt, the inculpatory facts must be incompatible with the innocence of the accused and incapable of explanation upon any other reasonable hypothesis than that of guilt.
p. 8Test for circumstantial evidence
Possession of an article which is proved to be connected directly with a crime after commission of the crime may, in certain circumstances, lead to the irresistible inference that the possessor of the article participated in the crime.
p. 9Recent possession doctrine
We agree with Mr. Sangoro that ordinarily there is no scientific basis of a ballistics expert to state with certainty that a particular bullet or cartridge was fired from a particular gun.
p. 8Limits of ballistics expert opinion
But such rejection cannot be capricious or whimsical. As stated in the Dhalay Case, there must be a "proper and cogent basis" for its rejection.
p. 8Standard for rejecting expert opinion
Circumstantial evidence is very often the best evidence. It is evidence of surrounding circumstances which, by undersigned coincidence, is capable of proving a proposition with the accuracy of mathematics.
p. 9Value of circumstantial evidence (quoting R v Taylor, Weaver and Donovan)
It is trite law that a single witness can be relied on for proof of a fact as no particular number is required to do so.
p. 6Evidence of a single witness
