Adiel Muriithi Phillip v Thomas Maingi
The bottom line
#Supreme Court struck out appeal because it was a civil dispute, not a constitutional matter.
What this practically means
#This case started as a car accident claim in the High Court. The parties agreed to settle for a lower amount, and the defendant paid. The plaintiff later tried to go back on the agreement and enforce the original judgment. The High Court and Court of Appeal said the settlement was binding. The plaintiff appealed to the Supreme Court, arguing constitutional issues. The Supreme Court said the case was purely a civil dispute, not a constitutional matter, so it could not hear it. The appeal was struck out.

Key legal issues
#Whether the appeal involves constitutional interpretation or application under Article 163(4)(a)
The appeal does not involve any issue of constitutional interpretation or application; it is purely a civil dispute over a consent judgment.
The Court examined the history of the case, which originated from a running down claim in the High Court. The appellant's grounds of appeal in the Court of Appeal revolved around the effect of a consent letter compromising the decree. The Supreme Court found no constitutional issue was raised or litigated in the lower courts. The appellant's argument that Justice Lenaola sat on appeal of a coordinate judge was rejected because Lenaola did not reverse the judgment but merely held parties bound by their consent.

- A civil dispute over a consent judgment does not become a constitutional matter by alleging constitutional violations.
- Parties cannot create Supreme Court jurisdiction by framing civil disputes as constitutional issues.
- The Supreme Court will strike out incompetent appeals 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.
To be competently before this Court, an appeal under Article 163(4)(a) of the Constitution must relate to a matter involving the interpretation or application of the Constitution that has actively been litigated before the High Court or Courts of coordinate jurisdiction as well as before the Court of Appeal.
It follows that this appeal is therefore incompetent. Consequently, we uphold the Preliminary Objection and hereby strike out this appeal with costs to the respondent.
Key timeline
#Practical implications
#Jurisdictional threshold for appeals
Lawyers must ensure that any appeal to the Supreme Court under Article 163(4)(a) involves a constitutional issue that was actively litigated in the High Court and Court of Appeal. Merely alleging constitutional violations in a civil dispute will not suffice. This case reinforces the need to identify and argue constitutional questions from the outset.
Binding effect of consent judgments
Businesses should be aware that once a consent judgment is agreed and payment accepted, it is binding. Attempting to renege on such settlements will likely fail in court. This case underscores the importance of finality in settlements.
Supreme Court jurisdiction limits
Individuals should know that the Supreme Court only hears cases involving constitutional interpretation. If your case is a civil dispute, the Supreme Court will not hear it, even if you try to frame it as a constitutional issue. Seek legal advice on the appropriate court for your appeal.
