Bett v Cabinet Secretary, Ministry of Land, Housing and Urban Development & 8 others (Constitutional Petition E010 of 2024) [2026] KEELC 2347 (KLR)
The bottom line
#Kenya's Environment and Land Court struck out a land petition as res judicata, confirming you generally get only one chance to litigate the same dispute.
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 25th November 2025 meets the threshold of what amounts to a proper preliminary objection
- 2.Whether the instant suit is res judicata
Key legal issues
#Whether the preliminary objection meets the Mukisa Biscuits threshold
Yes - the res judicata objection is a pure point of law evident from the pleadings, so the objection is properly raised by way of preliminary objection
The court reviewed Mukisa Biscuits, Aviation & Allied Workers Union and Catherine Kawira on the threshold of a pure point of law. It held res judicata is generally a pure point of law where identity of parties, subject matter and cause of action is evident from the pleadings, but becomes a mixed question of fact requiring a Notice of Motion where deeper factual inquiry is needed. Here, comparison of the two petitions sufficed, so the objection was proper. It also held section 7 of the Civil Procedure Act applies to petitions to fill a lacuna in the Mutunga Rules.
Whether the petition is res judicata having regard to the Mapelu Case
Yes - the parties litigate under the same title, the subject matter (five group ranches) and cause of action (evictions and title to the excised land) are the same, and the reliefs are similar
The court compared the reliefs sought in the Mapelu Case and in the instant petition and found substantial overlap: declarations of constitutional violations, compensation for eviction and injunctions concerning the same former group ranches. The petitioners were representative of landowners in the same ranches, litigating under the same title. The addition of CCM group ranch was a minor variation to obviate res judicata. Issues supposedly arising post-judgment were a tactic to frustrate enjoyment of the Mapelu judgment.
Legal principles established
#- The Mutunga Rules are the primary procedural regime for constitutional petitions, but the Civil Procedure Act may be invoked to fill lacunae, so section 7 on res judicata applies to petitions
- An objection of res judicata is a pure point of law suitable for a preliminary objection when identity of parties, subject matter and cause of action is evident from the pleadings; it becomes a mixed question of law and fact requiring a Notice of Motion if deeper factual inquiry is needed
- Parties cannot evade res judicata by adding other parties or causes of action, or by cosmetic variations such as adding a group ranch, and persons claiming under the same title are bound
- Res judicata applies to constitutional litigation but should be invoked in the rarest and clearest of cases, exempted only where substantial injustice or special circumstances are demonstrated
Court orders
#- 1.The Notice of Preliminary Objection dated 25th November 2025 by the 1st, 2nd, 3rd, 4th, 5th and 9th Respondents is found merited
- 2.The petition is found res judicata and struck out entirely
- 3.Each party to bear their own costs
The bench
#One judgment of the whole court — no separate or dissenting opinions.
Wrote the judgment
- Jurisdiction invoked
- Original constitutional jurisdiction of the Environment and Land Court over the petition; procedure governed by the Constitution of Kenya (Protection of Rights and Fundamental Freedoms) Practice and Procedure Rules 2013 (Mutunga Rules), with Section 7 of the Civil Procedure Act invoked to fill a lacuna
Relief refused
#The entire petition, including declarations of constitutional violations, compensation for unlawful eviction, permanent injunction and boundary-marking orders
The petition is res judicata, the issues having been determined in the Mapelu Case, and the petition was struck out in its entirety
Costs
Since this is a matter of public interest, each party to bear their own costs
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 the circumstances, we find the instant Notice of Preliminary Objection merited, finds the Petition herein Res judicata, and will proceed to strike it out entirely.
Since this is a matter of public interest, we direct that each party to bear their own costs.
the Mutunga Rules (2013), are the primary procedural guide for constitutional petitions, and where there is a lacuna, courts can invoke the provisions of the Civil Procedure Act and Rules, and thus section 7 of the Civil Procedure Act, is applicable herein
an objection on res judicata is generally a pure point of law, which means that it can be raised through a Preliminary Objection, just like the instant one, if the facts are clear from the pleadings
parties cannot evade the doctrine of res judicata by merely adding other parties or causes of action in a subsequent suit
the petitioners cannot litigate in piecemeal and expect to find audience in this court
The doctrine of res judicata, in effect, allows a litigant only one bite at the cherry.
Issues in the judgment
#The date of the Notice of Preliminary Objection is inconsistently stated within the judgment
The date of filing of the petition is stated in a way that conflicts with the objection chronology (objection dated November 2025 filed 'in response to the Petition herein dated 26th November 2024')
Typographical error in the holding on res judicata
