Key legal issues
#Whether the Supreme Court has jurisdiction to grant leave to adduce additional evidence in an election appeal governed by section 85A of the Elections Act.
The Supreme Court has jurisdiction to grant leave to adduce additional evidence, even in election appeals, because its jurisdiction under Article 163 of the Constitution is broader than that of the Court of Appeal and is not limited by section 85A.
The Court held that while section 85A limits appeals to the Court of Appeal to matters of law only, the Supreme Court's jurisdiction under Article 163 is broader and founded on the Constitution itself. Rule 18 of the Supreme Court Rules and section 21(3) of the Supreme Court Act empower the Court to take additional evidence for sufficient reason. The Court distinguished its earlier decision in Bichage, noting that the instant case involved evidence not already on record and that the Appellant sought to vindicate his academic credentials. The Court emphasized that it must not betray the Constitution and has a duty to do justice, especially where constitutional rights are at stake.
Whether the Appellant should be granted leave to adduce additional evidence regarding his academic qualifications.
Leave to adduce additional evidence was granted because the Appellant was not accorded a fair hearing at the trial court and Court of Appeal on the issue of his academic qualifications, and the additional evidence is directly relevant to the core issue in the appeal.
The Court found that the trial court disregarded a pre-trial consent that documents on record would not require strict proof, and the Appellant erroneously equated 'strict proof' to 'cross-examination', leading to his inability to properly defend his academic credentials. The Court noted that the Court of Appeal had considered only one issue (academic qualifications) and shelved all other grounds. The additional evidence sought (academic, educational and employment records) is directly relevant to that single issue and would likely impact the appeal. The Court concluded that disallowing the evidence would deny the Appellant a fair trial, a non-derogable right, and that allowing it would not prejudice any party.

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.
The emerging picture therefore is that this Court does have the jurisdiction to entertain an Application for additional evidence though this remedy should not be granted hastily.
We therefore lay down the governing principles on allowing additional evidence in appellate courts in Kenya as follows: (a) the additional evidence must be directly relevant to the matter before the court and be in the interest of justice; (b) it must be such that, if given, it would influence or impact upon the result of the verdict, although it need not be decisive; (c) it is shown that it could not have been obtained with reasonable diligence for use at the trial, was not within the knowledge of, or could not have been produced at the time of the suit or petition by the party seeking to adduce the additional evidence;
We are unconvinced that the Appellant was accorded a fair hearing at both the trial Court and the Appellate Court with regards to his academic qualifications.
Consequently, we make the following Orders: (i) The Application by the Appellant is allowed; (ii) The Appellant will serve the Respondents with the additional evidence by way of affidavit; (iii) The Respondents will respond to the additional evidence by way of affidavit; (iv) The Petition will be set down for hearing on a priority basis; (iv) Parties shall bear their own respective costs.

#Practical implications
#New pathway for additional evidence
Lawyers handling election appeals can now apply to the Supreme Court for leave to adduce additional evidence, even if the case was limited to points of law in the Court of Appeal. The ruling provides a clear checklist of 11 principles to argue, including relevance, diligence, and fairness. Use this to remedy procedural injustices from lower courts.
Fairness in qualification disputes
Businesses involved in electoral or regulatory disputes where qualifications are challenged should note that courts may reopen evidence if a party was denied fair hearing. Ensure all relevant documents are presented early and that pre-trial agreements are respected. This ruling reinforces the importance of procedural fairness in administrative and election matters.
Your right to prove qualifications
If you are a candidate whose academic or professional qualifications are questioned in an election petition, you have a right to present all relevant evidence. If lower courts did not give you a fair chance, the Supreme Court may allow you to introduce new documents. Act promptly and seek legal advice to preserve your rights.
