Kongo (Suing as the Legal Representative of the Estate of the Late Kiongo Njuguna) v Gatonye (Sued as the Legal Representative of the Estate of Peter Gatonye Kagimbi) & 7 others (Environment and Land Appeal E018 of 2024) [2026] KEELC 5086 (KLR)
The bottom line
#Kenya's Environment and Land Court ruled that res judicata cannot be decided through a preliminary objection; the dismissed land case returns to the lower court for a full hearing.
What this practically means
#Executive summary
#Key legal issues
#Whether res judicata may be determined via preliminary objection
No; determining res judicata requires probing of evidence and ascertainment of facts, so it is not a proper preliminary objection
Relying on four persuasive decisions, the court held that the plea of res judicata is anchored on evidential facts which must be properly raised, best by notice of motion with annexed pleadings, not by preliminary objection. Because the trial court treated it as a pure point of law, it committed an error of law warranting interference on appeal.
Whether the trial court could rely on judgments of the former suits not procedurally placed on record
It could not; the judgments were not procedurally introduced and the appellant was not heard on the issues of fact arising from them
Although the magistrate referenced the judgments in the 2018 suits, they were not formally introduced into evidence. Reliance on them to determine factual questions (identity of parties and subject matter) without affording the appellant a hearing breached fair-hearing requirements and vitiated the determination.
