Rwaru Mwangi v Republic
The bottom line
#Kenya's Court of Appeal quashed a death sentence because the trial record never showed what language the accused understood.
What this practically means
#Executive summary
#Key legal issues
#Whether failure to record the language chosen by the accused and to provide interpretation rendered the trial unlawful
Yes. The trial record showed no indication of the language chosen by the appellant, an unexplained mid-trial application for a Kikuyu interpreter, and no coram for the resumed hearing; the trial was conducted in contravention of the law and the appeal was properly conceded.
Section 77(2) of the (former) Constitution guarantees that an accused be informed in a language he understands and be permitted the assistance of an interpreter; section 198 of the Criminal Procedure Code governs interpretation of evidence in subordinate courts. Compliance can only be demonstrated on the face of the record. Here the record contained no indication of the appellant's chosen language, the interpreter application was unexplained, and the resumed hearing had no coram, so the trial contravened the law.
Whether a retrial should be ordered
No. Applying Muiruri v Republic and Mwangi v Republic, a retrial was undesirable and would not be proper in the circumstances.
The State did not seek a retrial. The court considered the settled factors: the illegality or defects in the original trial, the length of time elapsed since arrest and arraignment, whether the mistakes were entirely the prosecution's making, and whether a conviction might result on a proper consideration of admissible evidence. Taking all into account, an order for retrial would not be proper.
Legal principles established
#- The language in which criminal proceedings are conducted is not a mere technicality; it is constitutionally and statutorily grounded, and the burden is on the trial court to demonstrate on the face of the record the language the accused chose for the trial.
- The only way a trial court demonstrates compliance with the language and interpreter provisions is by showing, on the face of the record at the beginning of the trial, the language the accused person has chosen to speak.
- A retrial is ordered only where the interests of justice require it and it is unlikely to cause injustice to the appellant, having regard to defects in the original trial, the time elapsed, and whether the mistakes were the prosecution's making.
