John Omolo Oracha & 3 others v Kenya Petroleum Refineries Ltd & 3 others [2017] KECA 622 (KLR)
The bottom line
#Kenya's Court of Appeal confirmed that a land ownership judgment binds even non-parties, so the occupants' new constitutional petition was struck out as res judicata.
What this practically means
#Executive summary
#Key legal issues
#Whether res judicata may be raised as a preliminary objection
Yes - where the facts are uncontested, res judicata is a pure question of law suitable for a preliminary objection.
The court reaffirmed the Mukisa Biscuits and Supreme Court formulations: a preliminary objection must rest on a point of law with no contest as to facts. Because the plea of res judicata was pleaded and the relevant facts (the earlier judgment) were undisputed, the trial judge could determine it on the pleadings alone without hearing evidence.
Whether the petitioners were the same parties as, or claimed under, the defendants in HCCC No. 544 of 2000
They claim under the same title; all occupiers interested in the suit property are deemed to claim under the litigants in the former suit.
Explanation 6 to section 7 deems all persons interested in a right litigated bona fide in common for themselves and others to claim under the person litigating. The appellants, claiming to act for residents occupying the suit property, share a common interest with the earlier defendants, so privity of parties was satisfied.
Whether a different cause of action (constitutional rights violation) escapes res judicata
No - matters that ought to have been raised in the former suit are deemed to have been in issue.
Relying on explanation 4 to section 7 and Henderson v Henderson, the court held the appellants should have brought their whole case in the earlier suit, even by amendment. The constitutional claims arising from the same occupation of the same property ought to have been raised then and could not found a fresh petition.
Effect of a judgment in rem on non-parties
A judgment in rem on land ownership binds the whole world, including the appellants who were not parties.
The court adopted the reasoning in Kamunyu v Attorney General and C. L. Pasupathy that a judgment in rem operates on the thing or status rather than the person and binds all persons to the extent of their interest in the res, whether or not they were parties. The High Court's ownership and possession determination therefore bound the petitioners.
Legal principles established
#- A preliminary objection must be founded on a pure point of law based on undisputed facts; res judicata, where facts are not contested, is such a point of law.
- Persons claiming a common interest in property are deemed to litigate under the same title with those who litigated over that interest previously (explanation 6, section 7 Civil Procedure Act).
- A judgment in rem on ownership of land binds the whole world, including non-parties.
