Daniel Nzioka & Simon Maina v Republic [2019] KECA 6 (KLR)
The bottom line
#Kenya's Court of Appeal refused to add new evidence to a murder appeal because the applicants never tried to get that evidence during their trial.
What this practically means
#Executive summary
#Key legal issues
#Jurisdiction to admit additional evidence on appeal from a superior court's original jurisdiction
The Court has jurisdiction to admit additional evidence only where it acts as a first appellate court from a superior court's original jurisdiction decision, such as a conviction for murder
Rule 29 empowers the Court, for sufficient reason and in its discretion, to take additional evidence or direct that it be taken by the trial court or a commissioner. The Court relied on Muemi Nzale Wambua to confirm this jurisdiction exists only where a pending appeal from a superior court's original jurisdiction exists, as in murder convictions, which was the case here.
The principles governing leave to adduce additional evidence
Leave is generally granted where the evidence could not with reasonable diligence have been obtained at trial, would probably have an important influence on the result, and is apparently credible; the Mohamed Abdi Mahamud principles expand this to exceptional, case-by-case assessments including relevance, credibility, and whether the evidence seeks to fill gaps
The Court traced the jurisprudence from The Administrator, HH The Aga Khan Platinum Jubilee Hospital v Munyambu through Muemi Nzale Wambua to the Supreme Court's decision in Mohamed Abdi Mahamud, adopting the enumerated principles including relevance, influence on the verdict, reasonable diligence, credibility, non-voluminousness, fairness, and the bar on using additional evidence to patch weak points in a case.
Whether the applicants satisfied the principles for admission of additional evidence
They did not: the proceedings and Occurrence Book were readily available at trial but no application was made for their production, and no sufficient basis for the exercise of discretion was laid
Counsel conceded no application had been made before the trial judge for production of the magistrate's court proceedings or the Occurrence Book. The materials were readily available at trial, so the reasonable-diligence limb failed. The Court found no material upon which to exercise its discretion and dismissed both motions.
