Rwaru Mwangi v Republic [2007] KECA 338 (KLR)
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
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the trial was conducted in contravention of the constitutional and statutory provisions on the language of the trial and the right to an interpreter
- 2.Whether an order for retrial should be made if the appeal were allowed
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.
Court orders
#- 1.The appeal is allowed
- 2.The conviction of the appellant is quashed
- 3.The sentence of death imposed on the appellant is set aside
- 4.The appellant shall be set at liberty unless he is otherwise lawfully held
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court of Kenya at Meru
- H.C. Cr. A. No. 158 of 2004
- Jurisdiction invoked
- Second appeal to the Court of Appeal from the High Court on issues of law, in a criminal appeal; constitutionally grounded in the right of appeal and heard as a final appeal on matters of law
Relief refused
#Retrial
The State did not ask for a retrial and, taking into account the settled principles - the defects in the original trial, the lapse of time, and the prospects of conviction - the court held a retrial undesirable and improper
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.
the matter of language in which criminal proceedings are conducted is not a mere technicality. It has its foundation in the Constitution and in the Criminal Procedure Code, Cap 75
the only way a trial court would demonstrate compliance with those provisions is to show, on the face of the record at the beginning of the trial, the language which the accused person has chosen to speak
It is clear in the above circumstances that the trial was conducted in contravention of the law and the Principal State Counsel properly, in our view, conceded the appeal.
In the result, we allow this appeal. We quash the conviction of the appellant and set aside the sentence of death imposed on him. The appellant shall be set at liberty unless he is otherwise lawfully held.
Issues in the judgment
#The judgment records the first appeal as decided by Onyancha & Sitati, JJ.A, but the parenthetical describing the first-instance court refers to them as 'the learned Judges of the superior court (Onyancha/Sitati, JJ)', which is slightly inconsistent in describing the appellate bench below.
The judgment header lists the appeal as from a judgment of the High Court at Meru '(Onyancha & Sitati, JJ.A)', describing High Court judges with the rank suffix JJ.A, which is inconsistent with the court below being the High Court.
