Asanga v Oyale & 3 others (Enviromental and Land Originating Summons E005 of 2024) [2025] KEELC 8286 (KLR)
The bottom line
#A Kenyan court confirmed you cannot kill a lawsuit with a res judicata preliminary objection when the claim depends on disputed facts that still need evidence.
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 preliminary objection dated 29th January 2025 is a proper preliminary objection
- 2.Whether the preliminary objection is merited (i.e. whether the suit is res judicata)
Key legal issues
#Whether a plea of res judicata can be sustained via preliminary objection
No - because establishing res judicata depends on disputed/evidential matters, it is not a pure point of law.
The court adopted the Mukisa Biscuits and Oraro v Mbaja definitions of a preliminary objection, then set out four elements a defendant must prove for res judicata: identical issues/parties/subject matter, a final judgment, a judgment on merit, and a competent court. Since proof of a merit determination rests on evidence, the objection cannot be a pure point of law and was struck out.
Elements of res judicata under section 7 of the Civil Procedure Act
Res judicata requires identity of issues, parties, subject matter and cause of action; a final judgment on merit by a competent court.
The court reproduced section 7 of the Civil Procedure Act in full, including its explanations, and distilled four proof requirements for a defendant pleading res judicata. It held the doctrine bars retrial of matters directly and substantially in issue between the same parties already determined on merit with finality by a competent court.
Legal principles established
#- A valid preliminary objection must raise pure points of law founded on undisputed facts
- Whether a suit is res judicata requires proof of a merit determination of the former suit by a competent court and cannot be decided on a preliminary objection
Court orders
#- 1.The preliminary objection dated 29th January 2025 is struck out with costs
The bench
#One judgment of the whole court — no separate or dissenting opinions.
Wrote the judgment
- Jurisdiction invoked
- Original civil jurisdiction; suit alleging res judicata under section 7 of the Civil Procedure Act (former suit: Kakamega CMC ELC Case No. 180 of 2021)
Relief refused
#Striking out the plaintiff's suit on grounds of res judicata and abuse of court process
Whether the former suit was determined on merit between the same parties rests on evidence and is not a pure point of law capable of determination on a preliminary objection
Costs
The preliminary objection was struck out with costs (costs to the plaintiff).
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.
A preliminary objection is a pure point of law raised where facts are not disputed.
for a preliminary objection to be deemed to be valid, it must raise pure points of law and be anchored on facts that are not in dispute.
In the premises, I find and hold that the preliminary objection herein dated 29th January 2025 is not a proper preliminary objection and the same is hereby struck out with costs.
It is so ordered.
Issues in the judgment
#The judgment does not state the case number of the suit or the names of the parties; it also refers to the objector as 'respondent' in paragraph 7 despite the parties being styled plaintiff and defendants.
