Dr. William Gacani Mberia v Charles Kirimi Mbui & 4 others
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
#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.
