Key legal issues
#Whether the suit was res judicata
The suit was res judicata and was struck out
The plaintiff had previously sued the same defendants in Marimanti PMC E&L Case No E010 of 2021 seeking injunctive relief over the same land. That suit was dismissed as time-barred under Section 7 of the Limitation of Actions Act, and the dismissal was upheld on appeal by Yano J in Chuka ELC Appeal No E011 of 2023. The elements of res judicata were conjunctively satisfied: same parties, same subject matter, same cause of action, heard and finally determined by competent courts. Under Section 7 of the Civil Procedure Act and the principle in Henderson v Henderson, the plaintiff could not relitigate the same claim.
Whether the extension of time granted by the Court of Appeal preserved the plaintiff's right to sue afresh
It did not; the plaintiff squandered the opportunity granted and cannot file a fresh suit
The plaintiff was granted leave to appeal out of time by the Court of Appeal (Muchelule JA) on 28/6/2024 but did not utilise the window. Having elected not to pursue the appeal, he could not circumvent the final determination by instituting a new suit in the ELC raising the same claims against the same defendants.
Legal principles established
#- The elements of res judicata are conjunctive rather than disjunctive and must all be established
- Where a suit is res judicata, the Environment and Land Court lacks jurisdiction to entertain it
- Costs follow the event unless grounds for departure are shown (Section 27, Civil Procedure Act)
Court orders
#- 1.The notice of motion dated 9/9/2025 is allowed
- 2.The suit is struck out for being res judicata
- 3.The plaintiff shall bear costs of the suit
The bench
#One judgment of the whole court — no separate or dissenting opinions.
Wrote the judgment
- Jurisdiction invoked
- Article 162(2) Constitution / Environment and Land Court Act - the court acted as the Environment and Land Court at Chuka hearing a notice of motion to strike out a suit; Section 7 of the Civil Procedure Act invoked on res judicata
Relief refused
#The plaintiff's suit seeking declaration of ownership, eviction, permanent injunction and general damages for trespass
The suit was struck out as res judicata, the same claims having been determined in Marimanti PMC E&L Case No E010 of 2021 and upheld on appeal
Costs
Costs to the defendants/applicants - the plaintiff shall bear costs of the suit
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.
This suit is accordingly struck out for being res judicata.
The jurisdiction of the Environment and Land Court stands ousted by the doctrine of res judicata as spelt out in Section 7 of the Civil Procedure Act.
Consequently, the plaintifi shall bear costs of the suit.
the doctrine of res judicata is based on the principle of finality which is a matter of public policy
the plaintifi is precluded from bringing the present suit against the defendants.
Issues in the judgment
#The plaint is described as against 'the defendant' yet two defendants (1st and 2nd) are referred to throughout, and reliefs refer to 'the 2nd defendant'; the coram of the prior suit lists both as defendants in the present suit.
The judgment refers to the bar arising 'By dint of Section 7 of the Civil Procedure Act' when discussing the Limitation of Actions Act bar, apparently conflating Section 7 of the Limitation of Actions Act with Section 7 of the Civil Procedure Act.
The judgment is styled a ruling on a striking-out application, but the disposition also orders costs 'of the suit' before the suit was determined on merits.
