The bottom line
#Kenya's Court of Appeal dismissed a landowner's constitutional petition, confirming that ordinary land disputes like trespass and boundaries belong in civil suits, not constitutional litigation.
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 placed before the court a valid constitutional petition
- 2.Whether the issues raised in the constitutional petition were res judicata in light of Meru ELC Suit No. 151 of 2016
Key legal issues
#Whether the petition raised a valid constitutional claim
It did not; the grievance was a boundary/trespass dispute cognizable in a civil suit, and the petition failed the Anarita Karimi Njeru precision standard
The appellant did not set out the constitutional provisions infringed, his complaint, or the manner of infringement. His own pleadings described trespass and a wrongly referred boundary dispute, which are matters for an ordinary civil suit. Courts have repeatedly held that constitutional litigation is not a panacea and the first port of call should be suitable statutory forums.
Whether the petition was res judicata
It was; Meru ELC No. 151 of 2016 conclusively determined the boundary issue on a preliminary objection and that finding was affirmed in Civil Appeal No. 102 of 2020
A preliminary objection raising a pure point of law conclusively determines a suit; in ELC No. 151 of 2016 the court found the issue was one of boundaries and declined jurisdiction, and that decision was affirmed on appeal. The doctrine of res judicata serves order and efficacy, prevents multiplicity of suits, and brings litigation to an end; parties cannot evade it by cosmetic re-litigation dressed as a constitutional petition.
Legal principles established
#- A party must set out with reasonable precision the constitutional provisions said to be infringed and the manner of infringement; not every complaint is a constitutional issue, and constitutional litigation is not a panacea for all litigation.
- A preliminary objection raising a pure point of law can conclusively determine a matter, and a determination on such an objection, once affirmed on appeal, founds res judicata.
- Issues of trespass, wrong placement of a boundary or boundary disputes belong in an ordinary civil suit, not a constitutional petition.
- On a first appeal, the Court of Appeal must reconsider and re-evaluate the evidence and reach its own independent conclusions.

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.
In conclusion, the suit fails on all grounds. The petition in the High Court did not raise any constitutional issue and is res judicata on account of ELC No. 151 of 2016. The appeal is therefore dismissed with costs to the respondents.
not all complaints are constitutional, and not all wrongs qualify or can be christened as raising constitutional issues. Constitutional litigation is not a panacea for all litigation
A preliminary objection can conclusively determine a matter if it raises a pure point of law which, if resolved in favour of the opponent, would render the rest of the proceedings unnecessary or impossible.
The doctrine of res judicata, in efiect, allows a litigant only one bite at the cherry.
This being a first appeal, it is our duty in addition to considering submissions by the appellants and the respondents, to analyze and re-assess the evidence on record and reach our own independent conclusions in the matter.
Issues in the judgment
#The case title, appeal number and neutral citation of this Court of Appeal appeal are not stated in the judgment text; only the underlying Constitutional Petition No. 6 of 2020 and Meru ELC Suit No. 151 of 2016 are named. The case title field above is an approximation.
The names of the parties other than by ordinal designation (1st to 5th respondents) are not given in the judgment text, so the parties list records their designations.
The ruling of the High Court being appealed is described as both a striking out of the petition and, in the respondent's submissions, a dismissal; the judgment itself uses both formulations.
