Republic v Simon Mwangi Maina alias King'angii & Ano
The bottom line
#The High Court barred prosecutors from calling witnesses whose statements were never shared with the defence, reinforcing Kenya's fair trial disclosure rules.
What this practically means
#Executive summary
#Key legal issues
#Duty of disclosure under Article 50(2)
Disclosure is continuous but must not be used to ambush the defence; witnesses whose statements were not supplied cannot be called.
The court grounded the accused's entitlement in Article 50(2) and held the fair trial right non-derogable under Article 25. It adopted the Cholmondeley articulation of the prosecutor as a minister of justice bound to disclose all material, and held that late production of statements would abrogate the accused's rights and cause unnecessary adjournments.
Legal principles established
