Muasya v Mailu (Environment and Land Appeal E001 of 2023) [2025] KEELC 6114 (KLR)
The bottom line
#Kenya's Environment and Land Court refused to let an appellant add new evidence on appeal because he could have obtained it before trial.
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 appellant should be granted leave to adduce additional evidence on appeal
Key legal issues
#Whether the appellant should be granted leave to adduce additional documentary evidence on appeal
The application was dismissed because the evidence could have been obtained with reasonable diligence before judgment and is an attempt to fill gaps and patch weak points
The court applied the Supreme Court's Mohamed Abdi Mahamud criteria. Although the surveyor's report and letter were directly relevant to whether the cut trees were on the suit property, that relevance was always within the appellant's knowledge, he never sought the documents before judgment, and no denial or unavailability was shown. Reasonable diligence would have produced the documents at trial, so allowing them would let an unsuccessful litigant present a fresh case on appeal.
Legal principles established
#- Leave to adduce additional evidence on appeal is granted only in exceptional circumstances and the applicant must substantially satisfy the Mohamed Abdi Mahamud principles, which are not conjunctive

#- 1.Notice of motion dated 7/07/2023 dismissed with costs to the respondent

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.
this court ultimately finds the notice of motion dated 7/07/2023 unmeritorious, and it is hereby dismissed with costs to the respondent
the attempt by the appellant to introduce additional evidence on appeal is made by him as an unsuccessful party to present a new case on appeal, fill in omissions, and patch up weak points in the case
The principles outlined in Mohamed Abdi Mahamud (Supra) are not conjunctive. Nevertheless, an applicant, in this case the appellant, must meet the criteria substantially.
Issues in the judgment
#Date inconsistency: the body of the ruling records submissions dated January 2024 yet the ruling is delivered and dated 23 September 2025 without explanation, and the substantive appeal (filed 10/03/2023) remains pending
