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
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the applicants have met the threshold for the Court to review its own judgment dismissing their appeal, on the ground of newly discovered evidence
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.
Court orders
#- 1.The application dated 2nd February 2026 is dismissed
- 2.No orders as to costs
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- Environment and Land Court of Kenya at Chuka
- ELC OS No. 1 of 2019 (consolidated with ELC OS No. 20 of 2019)
- Jurisdiction invoked
- Residual jurisdiction of the Court of Appeal to review its own judgment, invoked under Section 3 of the Appellate Jurisdiction Act, Section 3 of the Judicature Act, Rule 1(2) of the Court of Appeal Rules 2022 and Articles 50 and 159 of the Constitution
Relief refused
#Review, variation and/or setting aside of the Court of Appeal judgment of 11th December 2025 dismissing the appeal
The new evidence (Area Chief's letter) was belatedly sought and obtained; applicants failed to exercise due diligence and sought to patch up a weak case
Setting aside of the ELC judgment of 25th May 2021 and remittal for retrial
Not permissible as a basis for exercising the Court's very narrow review jurisdiction
Costs
No orders as to costs, as the respondents did not participate in the appeal
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.
We reiterate that position and stress that this Court is clothed with residual jurisdiction to reopen and rehear a concluded matter where the interest of justice demands, but that such jurisdiction will only be exercised in exceptional situations where the need to obviate injustice outweighs the principle of finality in litigation.
Due diligence, as we understand it in the context of litigation would refer to the standard of prudence, reasonable care, and active inquiry expected of a party in legal proceedings.
A party who has been unsuccessful at the trial must not seek to adduce additional evidence to, make a fresh case in appeal, fill up omissions or patch up the weak points in his/her case.
The application fails and is hereby dismissed. As the respondents did not participate in the appeal, we make no orders as to costs.
