The bottom line

#

Kenya's Environment and Land Court dismissed Kajiado property owners' bid to stop demolitions, ruling their case had already been decided and couldn't be filed again.

What this practically means

#

Executive summary

#
The Plaintiffs, 14 registered owners of properties in Helena Estate, Kajiado North, sought conservatory orders under Order 40 Rule 1 of the Civil Procedure Rules restraining the County Government of Kajiado from demolishing, evicting or interfering with their properties pending determination of their suit. The suit was anchored on a challenge to the County's notice dated 11th May 2023 requiring demolition of structures encroaching on the Fatima Road road reserve. The Defendant opposed the application, contending that the court was functus officio, that the suit was res judicata having regard to the judgment of Komingoi J delivered on 19th June 2025 in Kajiado ELC Petition Case No. E001 of 2023 involving the same 14 claimants and the same notice, and that the Plaintiffs had not exhausted the dispute resolution mechanism under Section 40(4) of the Physical and Land Use Planning Act. The court framed three issues: res judicata, exhaustion of statutory mechanisms, and whether a prima facie case had been made out. Applying Section 7 of the Civil Procedure Act, the Supreme Court's rationale in John Florence Maritime Services, the conjunctive elements in IEBC v Kiai, and the test in Samuel Njau Wainaina against suits disguised as new claims, the court found the claimants identical, the subject matter the same, and the omission of the National Land Commission inconsequential. The suit was held to be res judicata and the application incompetent and unmerited. The other issues were not addressed. The application was dismissed with costs to the Defendant, and interim orders previously issued were vacated.

Key legal issues

#
01

Whether the suit and application offend the doctrine of res judicata

Holding

Yes. The suit is res judicata as it re-litigates the same subject matter (the 11th May 2023 demolition notice) between identical parties already determined in Kajiado ELC Petition Case No. E001 of 2023.

Reasoning

The court compared the pleadings in both matters and found the claimants identical and the contested issue the same — the County Government's notice dated 11th May 2023 requiring demolition of structures encroaching the road reserve. The only variance, the omission of the National Land Commission, was inconsequential. Applying Section 7 of the Civil Procedure Act and the conjunctive elements in IEBC v Kiai, the court held the second suit evades res judicata despite cosmetic differences in prayers.

02

Whether the Plaintiffs exhausted the statutory alternative dispute resolution mechanism under Section 40(4) of the Physical and Land Use Planning Act

Holding

Not determined; the court found it unnecessary given the res judicata finding.

Reasoning

Having concluded that the suit is res judicata and the application incompetent and unmerited, the judge expressly declined to address the exhaustion issue and the prima facie case issue, holding the res judicata finding sufficient to dispose of both the application and the entire suit.

Legal principles established

#
  • Res judicata bars re-litigation of the same subject matter between the same parties even where the subsequent suit is framed as a new cause of action or omits a party
  • Parties cannot evade res judicata by adding other parties or causes of action in a subsequent suit
