MAKAU MDATA v REPUBLIC [2007] KECA 260 (KLR)
The bottom line
#Kenya's Court of Appeal quashed a murder conviction built only on circumstantial evidence because the prosecution failed to exclude every reasonable innocent explanation.
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 conviction, founded solely on circumstantial evidence, was safe and could stand.
- 2.Whether the inculpatory facts were incompatible with the appellant's innocence and incapable of explanation upon any other reasonable hypothesis than his guilt.
- 3.Whether there were co-existing circumstances weakening or destroying the inference of guilt, including the uninvestigated claim that the appellant was himself attacked by robbers on the night in question.
- 4.Whether the chain of evidence relating to the blood samples taken from the appellant and the deceased was established.
- 5.Whether expert evidence reporting blood only in the general grouping 'A', without distinguishing positive from negative sub-groups, could found a conviction.
Key legal issues
#Whether the conviction resting wholly on circumstantial evidence satisfied the test that the inculpatory facts exclude every reasonable hypothesis of innocence.
No. The inculpatory facts did not exclude other reasonable hypotheses, so the conviction was unsafe and could not stand.
The only evidence tying the appellant to the killing was blood of group A on the deceased's panga and on leaves picked along a blood trail of unmeasured length and unrecorded collection point. The two child eyewitnesses left the scene while the fight continued and never saw the deaths; the panga remained by the deceased, so other assailants may also have been cut; the second deceased's blood was never sampled; and the claim that the appellant was himself attacked by robbers was never investigated. Those co-existing circumstances rendered the inference of guilt unsafe.
Whether the burden of proving a circumstantial-evidence case ever shifts to the accused.
It does not. The prosecution must prove incompatibility with innocence, exclusion of any other reasonable hypothesis and the absence of co-existing weakening circumstances, throughout the trial.
Restating Rex v Kipkering arap Koske as read with Simoni Musoke, the court held that before a conviction on circumstantial evidence three requirements must be met: the inculpatory facts must be incompatible with innocence, incapable of explanation on any other reasonable hypothesis than guilt, and unweakened by co-existing circumstances. The burden of proving all three rests on the prosecution and never shifts to the accused, so gaps in the prosecution case could not be cured by the appellant's failure to prove his own account of a robbery attack.
Whether the chain of evidence relating to the blood samples was established.
No. The chain of custody of the appellant's blood sample, and the provenance of the deceased's sample, were left unproved, which was fatal on the only evidence relied on.
The appellant's blood was not taken at Kilifi or Malindi District Hospital where he was treated; Cpl. Jared later took him to an unnamed clinic, and never told the court who took the sample or when. Nobody disclosed who took the deceased's sample or when. Because the blood-group evidence was the only evidence supporting the capital charge, the court held that the chain of evidence had to be established and, that having failed, the circumstantial chain was incomplete.
Whether generic blood-grouping evidence, stated only as group A, could found a conviction.
No. Expert evidence on which a capital conviction rests must be specific; a conviction cannot safely rest on a general grouping shared by many.
The Government Analyst reported the appellant's blood and the stains on the panga and the leaves only as group A. The court took judicial notice that group A subdivides into positive and negative sub-groups, and that those sharing the general group A are many. Evidence on which a life hangs had to state the sub-group; a conviction could not safely rest on the mere fact of a shared general grouping.
The effect of the failure to investigate the appellant's claim that he was himself attacked by robbers that night.
The uninvestigated and undischarged claim remained a live co-existing circumstance that broke the chain of circumstances required to prove guilt.
From the night in question the appellant consistently told his brother Ali, and through Ali the police, who booked the report in the occurrence book, that he had been attacked by robbers; he repeated the account in his defence. There was evidence robbers were in the area that night. No investigation of the claim was ever carried out, its falsity was never established, and it therefore hung over the whole case, breaking the chain of circumstances.
Legal principles established
#- A conviction may rest on circumstantial evidence only where the inculpatory facts are incompatible with the innocence of the accused, incapable of explanation upon any other reasonable hypothesis than guilt, and unaccompanied by co-existing circumstances that would weaken or destroy the inference of guilt.
- The burden of proving the requirements for a conviction on circumstantial evidence lies on the prosecution and never shifts to the accused.
- Where forensic evidence such as blood grouping is the only evidence relied on in a serious charge, the chain of evidence must be established.
- It is dangerous to base a conviction on a general blood grouping shared by many people; expert evidence must state the specific sub-group.
- Where an accused's consistent exculpatory allegation is never investigated or shown to be false, it remains a co-existing circumstance that can break the chain of circumstances required to prove guilt.
Court orders
#- 1.Appeal allowed.
- 2.Conviction of the appellant for the murder of Kahindi Karisa quashed.
- 3.Sentence of death set aside.
- 4.Appellant ordered to be released forthwith unless otherwise lawfully held.
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court of Kenya at Malindi
- H.C. Cr. Case No. 3 of 2001
- Jurisdiction invoked
- First appeal against conviction and sentence from the High Court's original criminal jurisdiction in a capital murder trial (charge under section 203 as read with section 204 of the Penal Code); the judgment does not expressly cite the constitutional or statutory provision conferring the appellate jurisdiction.
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.
In the result, we allow the appeal, quash the conviction and set aside the sentence. We order that the appellant be released forthwith unless otherwise lawfully held.
First is that the inference of guilt can only be justified if the inculpatory facts are incompatible with the innocence of the accused and, second, that the same inculpatory facts are incapable of explanation upon any other reasonable hypothesis than that of guilt and lastly that the court has to be sure that there are no other co-existing circumstances which would weaken or destroy the inference.
The same case also establishes that the burden of proving those three requirements is upon the prosecution and never shifts to the accused at any time.
There is need for the chain of evidence to be established particularly as this was the only evidence that was relied on in such a serious charge.
We do feel that was necessary as those sharing the general group A are many and it would be dangerous to base a conviction on the mere fact that the blood sample of the appellant falls into that category.
In law, the appellant would be entitled to the benefits of such doubts as we feel it would be unsafe to uphold conviction in the face of the same doubts.
That the appellant's consistent allegation that he was himself the victim of an attack by robbers that fateful night was not investigated and found to be false allegation leaves that possibility hanging on the entire case and the chain of the circumstances required to prove his guilt was, in our view, broken.
Issues in the judgment
#The date of delivery is printed with a typographical error ('20h' for '20th' July 2007).
Internal timing inconsistency: Ali's discovery of the injured appellant is introduced as occurring 'that same night' but is timed '2.00 p.m.', and the police report of the assault is likewise booked at 2.00 p.m. on the same day.
The trial judge's passage on the 'four sources of blood' is reproduced twice in the judgment with materially different wording, so the two quotations of the same passage do not match.
