Mugambi & 5 others v Mwithi & 7 others
The bottom line
#Kenya's Court of Appeal refused to reopen a concluded land case because the applicants only gathered supporting evidence after losing.
What this practically means
#Executive summary
#Key legal issues
#Whether newly obtained evidence (a Chief's letter confirming long occupation) justifies review of a concluded Court of Appeal judgment
No. The evidence was belatedly sought and obtained for purposes of the application; the applicants showed no due diligence in obtaining it during the pendency of the litigation, and the application was an attempt to patch up a weak case.
The Court defined due diligence as the standard of prudence, reasonable care and active inquiry expected of a party in litigation. Litigation had been ongoing since 2019, yet there was no evidence the applicants approached the Chief's office before or during the ELC proceedings or before the appeal was heard. The Chief's office existed throughout; the letter was obtained on 28th January 2026 only after judgment. Applying the Supreme Court's additional-evidence principles in Mahamud, the application sought to fill evidentiary gaps and make a fresh case, which the narrow review jurisdiction does not permit.
Legal principles established
#- The Court of Appeal has residual jurisdiction to reopen and rehear a concluded matter only in exceptional situations where the need to obviate injustice outweighs the principle of finality in litigation.
- An applicant invoking the Court's narrow review jurisdiction must bring itself within those narrow confines; due diligence requires active inquiry during the pendency of litigation.
- Additional evidence cannot be used to fill gaps or patch up the weak points in an unsuccessful party's case.
