Mweke v Republic (Criminal Appeal 100 of 2022) [2023] KECA 1527 (KLR)
The bottom line
#Kenya's Court of Appeal upheld a defilement conviction but replaced a mandatory life sentence with 30 years, finding life imprisonment unconstitutionally indeterminate.

#Key legal issues
#Entertaining a new issue of alleged judicial bias raised for the first time in a second appeal
The issue of the trial magistrate's bias in another file was raised for the first time in the second appeal and should not be entertained, save for the limited exception of manifest illegality or unconstitutionality.
Following Alfayo Gombe Okello and Alwi Abdulrehman Saggaf, the Court held that issues not raised at the earliest opportunity ought not be entertained on second appeal. The efficiency and authority of a final appellate court depend on the assistance of judges below. However, the Court recognised a limited avenue where the decision is manifestly contrary to the law or the Constitution, such as a manifestly illegal sentence, because the Court is bound by the rule of law under Article 10.
Right to legal representation and fair trial
Although the appellant ought to have been informed of his right to legal representation at the commencement of trial, the failure did not occasion a failure of justice because he was legally represented later in the proceedings.
The Court agreed the appellant should have been informed of the right to legal representation before trial commenced, but found no prejudice: he was represented by counsel during his defence, and the High Court found no violation of his fundamental rights. The defect therefore did not vitiate the trial.
Failure to medically examine the appellant for the sexually transmitted infection
Failure to subject the appellant to a medical examination to confirm infection did not justify interference with the conviction where there was sufficient material on the record to convict.
The appellant relied on the provision of the Sexual Offences Act permitting medical examination of an accused. The Court held that while such examination may have been prudent, its absence was not fatal given the sufficient material on the record — the complainant's testimony, medical evidence and the mother's account — establishing penetration and identification.
Indeterminate life sentence
A life sentence without legislative definition of its duration is indeterminate, fails to account for individual circumstances, and calls for appellate interference; the Court substituted a definite term of 30 years.
The Court reasoned that a life sentence is only meaningful where the law prescribes what life entails; otherwise it becomes indeterminate, lends itself to indiscriminate application, and inflicts ever-increasing punishment the longer an offender lives. Noting the Supreme Court's recommendation in Muruatetu that Parliament legislate on what constitutes a life sentence, and that the Attorney General had not acted on it, the Court found it would be abetting injustice to leave the indeterminate sentence in place.
Legal principles established
#- In a second appeal, the Court of Appeal's mandate is limited to matters of law only and will not interfere with findings of fact unless the lower courts considered matters they ought not to have, failed to consider matters they should have, or were plainly wrong.
- A point of law not raised in the courts below should not be entertained on second appeal unless the evidence establishes beyond doubt that the facts, if fully investigated, would have supported the new plea — save where the decision is manifestly contrary to the law or the Constitution.
- The decision whether or not to allow recall of witnesses who have been cross-examined is discretionary and an appellate court cannot fault the trial court's exercise of that discretion.
- An indeterminate life sentence is objectionable where there is no legislative prescription of what 'life' entails, and an appellate court may interfere with it.
