Kamotho v Kamotho (Environment and Land Case E484 of 2025) [2026] KEELC 535 (KLR)
The bottom line
#Kenya's Environment and Land Court threw out a defendant's attempt to kill a land suit early, ruling res judicata must be argued with evidence, not raised as a technicality.
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 Notice of Preliminary Objection dated 28th October 2025 meets the threshold of a proper preliminary objection
- 2.Whether the res judicata and functus officio issues raised can properly be determined by way of a preliminary objection
Key legal issues
#Whether the objection satisfied the Mukisa Biscuits threshold of a preliminary objection
The objection did not meet the threshold because it required ascertainment of facts and scrutiny of evidence from prior proceedings.
To determine whether the issues in the previous suits were directly and substantially in issue and finally decided on merits, the Court would have to call for and scrutinise the pleadings, applications and rulings in Milimani ELC Case No. E300 of 2024 and Milimani CMCC No. E6834 of 2020. A preliminary objection cannot be sustained where facts have to be ascertained or judicial discretion exercised.
Proper manner of raising res judicata
Res judicata should be raised through a substantive application with pleadings and decisions from previous suits annexed.
Following George Kama Kimani & 4 Others v County Government of Trans-Nzoia, the Court held that comparing issues in prior suits requires annexing the prior pleadings and decisions, which cannot be done within the narrow confines of a preliminary objection that must stem purely from the pleadings and raise pure points of law.
Whether the functus officio contention was a pure point of law
The functus officio claim also required evidentiary inquiry and could not be determined on a preliminary objection.
Determining whether the Court was functus officio required interrogation of the substance and scope of the earlier rulings to establish whether the parties' rights were conclusively determined, an inquiry calling for evidence rather than a pure point of law on the pleadings.
Legal principles established
#- Res judicata involving factual ascertainment cannot properly be raised by way of preliminary objection; the proper manner is a substantive application with the prior pleadings and decisions annexed.
- A preliminary objection must raise a pure point of law on the assumption that all facts pleaded by the other side are correct.

For the foregoing reasons, the said Notice of Preliminary Objection is hereby dismissed in its entirety with costs being in the cause.
The matter shall be set down for hearing and determination on merits.
