Karanja & another v Republic (? 92 of 1990) [1990] KECA 50 (KLR)
The bottom line
#Kenya's Court of Appeal freed two men convicted of theft, ruling that witnesses who were originally charged and later paid must be treated as accomplices needing corroboration.
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 two pointsmen (PW 18 and PW 19) were accomplices notwithstanding the concurrent finding of the trial and first appellate courts to the contrary
- 2.Whether the convictions were based on uncorroborated accomplice evidence and were therefore unsafe
- 3.Whether the failure to consolidate Muchiri's appeal with the appellants' appeals resulted in unequal treatment
Key legal issues
#Whether the two pointsmen were accomplices
The Court found the pointsmen were accomplices, reversing the concurrent finding of the two courts below.
The pointsmen had originally been charged jointly with the appellants, their charges were withdrawn when they turned state witness, and each received Kshs.5,000 from Mungai in circumstances they could not credibly explain. The Court held that no reasonable tribunal properly directing itself could conclude otherwise, making the concurrent finding clearly erroneous and unsustainable.
Whether the convictions rested on uncorroborated accomplice evidence
The witnesses cited as corroboration (PW 9, PW 11 and PW 12) only mentioned Muchiri and not the appellants, so their evidence could not corroborate the pointsmen's testimony implicating the appellants; the convictions were unsafe.
Each of the alleged corroborating witnesses spoke only to Muchiri's involvement, making no mention of either appellant. Their evidence therefore failed the Baskerville test of independent evidence connecting the accused with the crime. The state counsel rightly conceded both appeals, and the Court quashed the convictions and set aside the sentences.
Consolidation of appeals arising from a joint trial
As a matter of policy, all appeals by jointly-tried convicted defendants should be consolidated and heard together unless clearly unavailable, to avoid speculation of discriminatory treatment.
Muchiri's appeal had been heard and disposed of ahead of the appellants' appeals for unexplained reasons, and his sentence was substituted with a fine, prompting a complaint of preferential treatment. The Court stated the consolidation policy to prevent such perceptions where all defendants have appealed.
Legal principles established
#- Where there has been a joint trial, all appeals filed by convicted defendants in the High Court should be consolidated and heard together unless it is clear that some defendants have not appealed.
- The uncorroborated evidence of an accomplice should generally be held untrustworthy and corroboration should be found before a conviction is based on it.
- Corroboration of an accomplice must be independent evidence connecting or tending to connect the accused with the crime, confirming in some material particular that the accused committed it.
- It is not necessary to confirm all circumstances of the crime; corroboration of some material particular tending to implicate the accused, even if merely circumstantial, is enough.
Court orders

- 2.Convictions quashed

- High Court of Kenya at Nakuru

Consequently we allow their appeals, quash the convictions, set aside the sentences and order that they be released forthwith from prison unless otherwise lawfully held.

An accomplice is of course a competent witness but corroboration should be found for his evidence before a conviction can be based upon it.
It must be independent evidence which affects the accused by connecting him or tending to connect him with the crime, confirming in some material particular not only the evidence that the crime has been committed but also that the accused committed it.
the uncorroborated evidence of such a witness should generally be held to be untrustworthy for three reasons. The accomplice is likely to swear falsely in order to shift the guilt from himself.
Issues in the judgment
#The judgment does not name the individual judges constituting the Court of Appeal bench; it states only 'the following Judgment of the Court was delivered', so no panel or judge opinions can be recorded.
The judgment contains no costs order notwithstanding the appeals being allowed.
