James Kamau Wainaina & another v Republic [2010] KECA 323 (KLR)
The bottom line
#Kenya's Court of Appeal freed two men convicted of murder because the prosecution never proved the cause of death, charged a non-existent offence, and dismissed the trial assessors too early.
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 failure to call the doctor who performed the post mortem examination, resulting in the cause of death not being proved, vitiated the conviction for murder
- 2.Whether the discharge of the assessors before the conclusion of the trial rendered the trial a nullity
- 3.Whether the conviction for 'conspiracy to conceal murder' under section 224 of the Penal Code was lawful, that offence not existing in law
- 4.Whether a retrial should be ordered
Key legal issues
#Proof of cause of death in a murder conviction
The conviction could not stand because the prosecution failed to call the doctor who performed the post mortem examination and the cause of death was never proved.
The appeal was founded on a charge of murder, but the doctor who conducted the post mortem was never called and no post mortem report was produced. Without that evidence it was impossible to establish the immediate cause of death, an essential element of murder. The State itself conceded on this ground, and the trial judge had relied on a prior Court of Appeal decision to the same effect.
Discharge of assessors before conclusion of trial
The discharge of the assessors before the completion of the trial rendered the entire trial a nullity; the repealing amendment did not affect the pending proceeding.
Assessors present at the start of the trial were discharged before its conclusion, apparently because the Criminal Procedure Code was amended to abolish assessors. Section 23(3)(e) of the Interpretation and General Provisions Act preserves pending proceedings notwithstanding repeal unless a contrary intention appears. The judge should therefore have retained the assessors to the end, and their mid-trial discharge nullified the whole trial, following Elirema v R.
Conviction for a non-existent offence
The conviction for 'conspiracy to conceal murder' was unlawful because no such offence exists; section 224 of the Penal Code creates only conspiracy to murder, punishable by a maximum of fourteen years, so the fifteen-year sentence was also unlawful.
The trial judge, unable to sustain murder, convicted the appellants of 'conspiracy to conceal the murder' under section 224. The court examined the text of section 224 and found it penalises only conspiracy to kill. A conviction for an offence unknown to law could not stand, and the sentence of fifteen years exceeded the statutory maximum of fourteen years even for conspiracy to murder.
Whether a retrial should be ordered
A retrial would not meet the ends of justice, given the defects in the original trial and the circumstances of the case.
Applying the principles in Mwangi v R and Muiruri v R, the court weighed the illegality and defects in the original trial, the length of time elapsed since arrest and arraignment, and the interests of justice. It concluded that an order for retrial would not meet the ends of justice, particularly as the State had not sought one and the appeal was conceded.
Legal principles established
#- There is no offence known as 'conspiracy to conceal murder'; section 224 of the Penal Code creates only conspiracy to murder, with a maximum sentence of fourteen years' imprisonment.
- Where a written law repeals another, under section 23(3)(e) of the Interpretation and General Provisions Act the repeal does not affect pending investigations, legal proceedings or remedies unless a contrary intention appears; thus a trial judge should have retained assessors to the end of the trial notwithstanding amendment of the Criminal Procedure Code.
- The discharge of assessors mid-trial renders the entire trial a nullity.
- A conviction for murder cannot be sustained where no post mortem report is availed and the cause of death is not established.
- A retrial should only be ordered where, on a proper consideration of admissible or potentially admissible evidence, a conviction might result, and where the interests of justice require it without causing injustice to the appellant.
Court orders
#- 1.The appeal is allowed
- 2.The conviction of the appellants and the sentence imposed on them are set aside
- 3.The appellants are to be set free 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 Nakuru
- H.C.CR.C. No. 41 of 2003
- Jurisdiction invoked
- First appellate jurisdiction over a conviction and sentence of the High Court (Criminal Appeal from the High Court)
Relief refused
#Retrial
The State did not seek one and the court found it would not meet the ends of justice given the errors in the original trial and time elapsed
Costs
No costs order made; this is a criminal appeal in which the appellants appeared in person and the State conceded.
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.
The upshot of the foregoing is that this appeal is allowed and we set aside the conviction of the appellants and the sentence imposed on them. The appellants are to be set free forthwith unless otherwise lawfully held.
Hence, while there is an offence known as “conspiracy to murder” there is no offence known as “conspiracy to conceal murder”.
The fact that the assessors were discharged mid-stream rendered the rest of the trial a nullity. Since there was only one trial it means the entire trial was rendered null and void
During the trial the prosecution failed to call the doctor who performed post mortem examination on the body of the deceased so that the cause of death was not proved.
A retrial should not be ordered unless the appellate court is of the opinion that on a proper consideration of the admissible or potentially admissible evidence a conviction might result.
It will only be made where the interest of justice requires it and if it is unlikely to cause injustice to the appellant.
Issues in the judgment
#The judgment states the appeal was 'allowed' and the conviction and sentence set aside, yet it also characterises the entire trial as a nullity; the framing of the case as a murder conviction is complicated by the fact that the trial judge had actually convicted of 'conspiracy to conceal murder'. The court does not expressly reconcile whether the appeal was from a murder conviction or the conspiracy conviction.
