Joseph Kamau Mwangi v Republic [2017] KECA 720 (KLR)
The bottom line
#Kenya's Court of Appeal upheld a murder conviction based purely on circumstantial evidence, but replaced the illegal 40-year sentence with the death sentence.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the offence of murder was proved beyond reasonable doubt on circumstantial evidence alone
- 2.Whether the two fired bullets examined by the ballistic expert were properly received in evidence or 'mysteriously introduced'
- 3.Whether the appellant was in possession of the Ceska pistol recovered in the Public Health Department compound
- 4.Whether inconsistencies and contradictions in the prosecution evidence, including the discrepancy in time of arrest and shooting, fatally weakened the case
- 5.Whether an adverse inference should have been drawn against the prosecution for failing to call vital witnesses
Key legal issues
#Sufficiency of circumstantial evidence for a murder conviction
The conviction founded solely on circumstantial evidence was upheld; the ballistic linkage of the Ceska pistol to the fatal bullets, the sighting of the appellant discarding the pistol, and his flight together formed an unbroken chain excluding innocence
The court found overwhelming evidence linking the fatal bullets to the pistol: matching ejector, breech face and firing pin markings on cartridges and matching land engraved areas on bullets. The identification evidence had been properly rejected, but PW2's continuous chase, the unbroken chain from discarding the pistol to arrest, the proximity of five metres, the street lighting, and the coincidence of two assailants and two fleeing men rendered the inference of guilt irresistible and excluded co-existing weakening circumstances.
Provenance of the two fired bullets
The two bullets were among the fragments removed from the body by the pathologist; their provenance was explained and they properly connected the pistol to the death
PW4 had testified to removing bullet fragments (in plural) from the body, and four entry wounds but only two exit wounds showed two bullets lodged in the body. The court accepted that what the pathologist called fragments the ballistic expert classified as one fragment and two fired bullets, satisfying itself that the Exhibit Memo Form and the medical evidence reconciled the apparent discrepancy.
Constructive possession of a discarded firearm
The appellant was in possession of the Ceska pistol notwithstanding that it was recovered outside his person, under the extended definitions of possession in the Penal Code and Firearms Act
Section 3 of the Penal Code and section 2 of the Firearms Act define possession to include knowingly having anything in any place for one's own or another's use or benefit. PW2 saw the appellant discard the pistol over the PHD wall during an unbroken chase; holding otherwise would be an artificial and absurd construction of the statute.
Failure to call witnesses and adverse inference
No adverse inference was warranted because the evidence called by the prosecution was not barely adequate; the Bukenya principle applies only in such cases
Following Donald Majiwa Achilwa, the court held that the prosecution must call all necessary witnesses but not a plurality of them. Since the ballistic and circumstantial evidence was overwhelming and the occupants of the car did not alight before the shooting, their omission could not justify an inference that their evidence would have been adverse to the prosecution.
Illegality of the 40-year sentence for murder
The sentence of 40 years imprisonment was illegal; the lawful sentence for murder being death, the court substituted it after duly warning the appellant
Before hearing the appeal the court drew counsel's attention to the illegality of the sentence, citing Joseph Njuguna Mwaura & 2 Others v. Republic, and warned that if the appeal failed it would be obliged to impose the death prescribed by law. The appellant elected to pursue the appeal, and on dismissal the court set aside the illegal sentence and substituted death.
Legal principles established
#- A conviction may properly be founded on circumstantial evidence alone if it is incompatible with the innocence of the accused and incapable of explanation on any other hypothesis than guilt, with no co-existing circumstances weakening the chain
- A person who discards an item to avoid arrest while being pursued continuously remains in constructive possession of that item under the extended statutory definition of possession
- An adverse inference from the prosecution's failure to call a witness arises only where the evidence called is barely adequate; the prosecution is not bound to call a plurality of witnesses
- On a first appeal the Court of Appeal must rehear the case and make up its own mind, while deferring to the trial judge on demeanor and credibility
- An appellate court, on dismissing an appeal against conviction for murder, must impose the lawful sentence where the sentence below was illegal, even after warning the appellant
Court orders
#- 1.Appeal against conviction dismissed
- 2.Sentence of 40 years imprisonment set aside
- 3.Sentence of death substituted as prescribed by law
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court of Kenya at Mombasa
- H.C.CR.C. No. 16 of 2008
- Jurisdiction invoked
- First appeal to the Court of Appeal under the Constitution and the Court of Appeal Act (appeal as of right on law and fact in a criminal appeal)
Relief refused
#Quashing of the murder conviction
Circumstantial evidence linking the appellant to the murder weapon was incompatible with innocence and unweakened by co-existing circumstances
Costs
No costs order made (criminal appeal)
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.
circumstantial evidence is as good as any evidence if it is properly evaluated and, as is usually put, it can prove a case with the accuracy of mathematics.
To found a conviction, circumstantial evidence must be incompatible with the innocence of the accused person; incapable of explanation upon any other hypothesis than that of guilt of the accused person; and there must be no other existing circumstances, which could weaken the chain of circumstances.
In our view it would also be an artificial and absurd interpretation of the statute to hold that a person who has been in actual possession of an item and has been perceived discarding it to avoid arrest, is not in possession of that item.
Ultimately we have come to the conclusion that this appeal lacks merit and the same is hereby dismissed. As the sentence of 40 years imprisonment imposed by the trial court for the offence of murder was an illegal sentence, and the appellant was duly warned, we hereby set it aside and substitute therefor the sentence of death as prescribed by law. It is so ordered.
Issues in the judgment
#The judgment states the trial court convicted the appellant on '14th June 2014' while the marginal note records the High Court judgment as 'dated 14th June 2012'; the two dates conflict.
The narrative description of PW1 switches: PW1 is initially Ashish Oza, an eyewitness, but later the arresting officers PC Jotham Nyaroche and PC Athanus Kivilu are also referred to as PW1 and PW2, creating internal inconsistency in witness numbering.
The identification witness at the scene is said to be disregarded because it was evidence of a single eyewitness 'PW8', although the eyewitness earlier described as alighting with the deceased was PW1 (Ashish Oza), an apparent internal numbering inconsistency.
