Benson Ngunyi Ndungu v Republic [1985] KECA 51 (KLR)
The bottom line
#Kenya's Court of Appeal quashed a murder conviction because prosecutors proved neither the cause of death nor the accused's identification.
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 cause of the deceased's death was established without medical or post-mortem evidence
- 2.Whether the evidence of identification at night by a single witness was sufficiently positive
- 3.Whether the deceased's statements at the scene were admissible as dying declarations under section 33(a) of the Evidence Act
- 4.Whether the trial judge properly assessed the credibility of the prosecution witnesses
- 5.Whether the appellant could instead be convicted of the lesser cognate offence of assault causing actual bodily harm under section 251 of the Penal Code
Key legal issues
#Proof of cause of death without medical evidence
The cause of death was not proved; absence of a post-mortem report was fatal to the murder conviction because the chain linking the assault, the treatment and the death was never established.
The only post-mortem report available was an unsigned, undated copy which was never properly produced. There was no evidence from the clinical officer at Matuu Health Centre, no explanation of the drugs given, and no evidence tying the treatment at the three health facilities to the injuries. The deceased's body turning yellow suggested death from a different illness, so the prosecution failed to prove the proximate cause of death.
Admissibility of the deceased's statements as dying declarations
The statements could not advance the prosecution case because admissibility under section 33(a) depended on proving that the circumstances stated caused death, which was not established.
Whether the deceased's statements to Anna and Mutiso fell within section 33(a) of the Evidence Act depended on whether the circumstances he mentioned resulted in his death. Since the cause of death was not proved, the statements could not be used. The court also observed that committal proceedings were sloppily prepared and the deceased's statement to Corporal Mwaka should have been exhibited to the magistrate.
Identification by a single witness at night
Identification by the single witness Mutiso was not positive; it could not support a conviction even for the lesser offence of assault causing actual bodily harm.
Mutiso flashed a five-cell torch and claimed to see the appellant and two others bending over the deceased before they ran away, but he did not say how much opportunity he had to see and identify them. Anna, who also carried a torch, said it was impossible to recognize a person in the darkness. On this first appeal the court rehearsed the evidence and found the identification unsafe.
Duty of a first appellate court
On a first appeal the Court of Appeal must reconsider the evidence as a whole and reach its own conclusions, guided by the trial judge's impressions of credibility.
The court restated its duty to rehear the case and satisfy itself that there was evidence upon which the judge could properly and reasonably reach his findings, citing Shantilal M Rawala v R and Answar Kimngetich v R. This re-evaluation led it to conclude that the prosecution case had collapsed on the cause of death and identification.
Quality of committal proceedings
Committal proceedings must be based on sufficient grounds and complete documents; a subordinate court should adjourn where a vital committal document is missing.
Under section 231(2)(c)(ii) of the Criminal Procedure Code a copy of any post-mortem report is a committal document, and under section 232(2) the magistrate must read the committal documents and be satisfied there are sufficient grounds for committal. The magistrate should have insisted on a signed report or the original, and should have adjourned if it was not furnished.
Legal principles established
#- A post-mortem examination report is the normal and straightforward means of proving cause of death, and the medical officer who performed it should be produced for cross-examination.
- A committal document which is undated and unauthenticated by the name or signature of its maker is not a valid copy and ought not to be accepted in committal proceedings.
- Even where injuries are so obvious that cause of death may be inferred without a post-mortem report, medical opinion evidence should still be adduced in support.
- Republic v Cheya and Another must be confined to its exceptional facts and does not illustrate the proper application of the principle that death may be established without medical evidence.
Court orders
#- 1.Appeal allowed
- 2.Conviction for murder quashed
- 3.Sentence of death set aside
- 4.Appellant to be set at liberty unless otherwise lawfully held

- Criminal Case No. 39 of 1984
- Jurisdiction invoked
- First appellate criminal appeal against conviction and sentence for murder under the Penal Code, heard as of right by the Court of Appeal
Relief refused
#Substitution of a conviction for assault causing actual bodily harm contrary to section 251 of the Penal Code
The identification by the single witness Mutiso was not positive and the evidence could not support the lesser offence
Costs
No order as to costs was made in the judgment
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.
Our conclusion is that the appeal must be and is allowed, the conviction quashed, the sentence set aside and the appellant shall be set at liberty unless otherwise lawfully held .
Here, no post-mortem examination report was produced. Very poor reasons were given for not producing it.
Where the body is available and the body has been examined, a post-mortem report must be produced
the decision must be confined to what must have been an exceptional situation, a great deal of which is not given in the judgment, that the judgment is misleading
Because the cause of death was not proved, the statements of the appellant did not advance the prosecution case.
We have no enthusiasm for incomplete and sloppily prepared committal proceedings which waste time and cause unnecessary hardship.
