Kusimba (Suing on Her Behalf and Behalf of the Estate of Nehemia Kusimba Omeri) v Okula (Sued on Behalf of the Estate of Isaac Clement Okula Omeri) (Enviromental and Land Originating Summons E033 of 2024) [2025] KEELC 6581 (KLR)
The bottom line
#The Busia Environment and Land Court ruled that earlier succession and magistrates' court cases over the same land cannot block a fresh adverse possession claim.
What this practically means
#Executive summary
#Key legal issues
#Whether the objection was a proper preliminary objection
The res judicata plea qualifies as a point of law under the Mukisa Biscuit definition
The court applied the locus classicus definition: a preliminary objection must be a pure point of law argued on the assumption that all facts pleaded by the other side are correct, and may dispose of the suit. Res judicata under Section 7 of the Civil Procedure Act satisfies this test and was therefore properly raised by notice of preliminary objection.
Whether Succession Cause No 173 of 2016 renders the suit res judicata
No - the Probate Court could not determine adverse possession or trust
The succession cause concerned a confirmed grant over the suit land, which was revoked on 9th March 2021. The court held that a Probate Court's mandate is distribution of the estate among beneficiaries; issues of adverse possession and trust were neither canvassed nor determinable in that forum, per Rule 41(3) of the Probate and Administration Rules.
Whether ELC Case No 126 of 2018 renders the suit res judicata
No - neither issue was determined, and adverse possession could not have been determined there for want of jurisdiction
Although the same parties litigated over ownership of the suit land in the 2018 case, the issues of trust and adverse possession were not pleaded or determined. Moreover, following the Court of Appeal in Sugawala, magistrates' courts lack jurisdiction over adverse possession claims, and a judgment by a court without jurisdiction cannot be res judicata.
Legal principles established
#- A Probate Court's duty is to distribute the estate; it cannot determine disputes of adverse possession or trust over estate property
- Magistrates' courts lack jurisdiction to hear and determine claims for adverse possession, which are limited to the Environment and Land Court
- A judgment delivered by a court without jurisdiction cannot found a plea of res judicata
Court orders
#- 1.The Preliminary Objection is dismissed with costs.
- 2.The Defendant is to file her response to the Originating Summons within 14 days so that directions can be taken and the suit listed for hearing.
- Jurisdiction invoked
- Article 162(2)(b) of the Constitution / Environment and Land Court Act - original jurisdiction over adverse possession and trust claims relating to land (as reflected in the court's reasoning that adverse possession is 'specifically limited to the Environment and Land Court')
