Kanyuira v Kenya Airports Authority
The bottom line
#Supreme Court rejects bid to add new evidence after 10-year delay, upholding earlier rulings.
What this practically means
#Patrick Thoithi Kanyuira wanted to introduce new letters in his appeal against Kenya Airports Authority. The Supreme Court said no because he waited ten years without a good reason. The letters could have been found earlier. The court also said the main issue was already decided. Allowing the evidence would unfairly harm the other side. The application was dismissed, and Mr. Kanyuira must pay costs.
Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.whether the applicant has met the threshold for the grant of leave to present additional evidence pursuant to rule 18 of the Supreme Court Rules,2012 and in accordance with the strictures established in the Mohamed Abdi Mahamud case
Key legal issues
#Whether the applicant met the threshold for leave to present additional evidence under rule 18 of the Supreme Court Rules, 2012.
The applicant did not meet the threshold because the evidence was not obtained with reasonable diligence, it was an attempt to make a fresh case or fill gaps, and allowing it would prejudice the respondent.
The court applied the eleven principles from Mohamed Abdi Mahamud. It found that the applicant delayed ten years without explanation, the evidence could have been obtained earlier from bodies that existed before the trial, and the central issue—which body has authority to approve construction near an airport—was already settled. The application was an attempt to patch up weak points, and the respondent would suffer prejudice if the evidence were admitted.
Legal principles established
#- Additional evidence must be directly relevant and in the interest of justice.
- The evidence must be capable of influencing the result, though it need not be decisive.
- The applicant must show the evidence could not have been obtained with reasonable diligence at trial.
- A court will not allow evidence that is an attempt to make a fresh case or fill gaps.
- Unexplained delay in seeking to adduce evidence weighs heavily against the application.
- Prejudice to the opposing party is a key factor in refusing additional evidence.

Key timeline
#Practical implications
#Strict criteria for appellate evidence
When advising clients on appeals, emphasize that the Mohamed Abdi Mahamud test is rigorous. You must show the new evidence could not have been obtained earlier with reasonable diligence. Delay without explanation is fatal. Do not use additional evidence to patch up a weak case; the court will treat it as an abuse of process.
Finality of court decisions matters
If you are involved in litigation, gather all supporting documents before trial. The court will not let you add evidence years later to change the outcome. This ruling protects the other party from unfair surprise and ensures cases end. Plan your legal strategy early and comply with deadlines.
Act promptly with your evidence
If you have a legal dispute, do not wait to collect documents or approvals. The court expects you to use reasonable diligence to find evidence before trial. Waiting ten years, as in this case, will likely lead to your application being dismissed. You may also have to pay the other side's legal costs.
Frequently asked questions
#Can I introduce new evidence in an appeal in Kenya?+
Yes, but only under strict conditions. The Supreme Court in Patrick Thoithi Kanyuira v Kenya Airports Authority confirmed you must show the evidence could not have been obtained earlier, is relevant, and would influence the result. Unexplained delay or trying to fill gaps will lead to dismissal.
What is the test for additional evidence in the Supreme Court of Kenya?+
The test comes from Mohamed Abdi Mahamud v Ahmed Abdullahi Mohamad. It has eleven criteria, including that the evidence must be directly relevant, could not have been obtained with reasonable diligence at trial, and must not be an attempt to make a fresh case. The court also considers prejudice to the other side.
How long do I have to appeal a land case in Kenya?+
Appeal timelines vary by court. Generally, you have 30 days from the judgment to file a notice of appeal in the Court of Appeal, and 14 days for the Supreme Court. However, applications to adduce additional evidence have no fixed deadline but must be made without unreasonable delay.
What happens if I delay filing evidence in a Kenyan court?+
Delaying without a good reason can be fatal. In Patrick Thoithi Kanyuira v Kenya Airports Authority, a ten-year delay led to dismissal. The court said you must act with reasonable diligence. If you wait too long, the court will likely refuse your application and may order you to pay the other side's costs.
