Uyoga v Ali & another (Environment and Land Case E222 of 2025) [2026] KEELC 2032 (KLR)
The bottom line
#Kenya's Environment and Land Court ruled that claims of res judicata need evidence, so they cannot be raised as a preliminary objection to strike out a suit.
What this practically means
#Executive summary
#Key legal issues
#Whether the Notice of Preliminary Objection dated 9th July 2025 meets the threshold of a true preliminary objection
It does not, because it is founded on matters requiring judicial inquiry and evaluation of facts
The Court applied the Mukisa Biscuits definition and Oraro v Mbaja principle that a preliminary objection must be a pure point of law with no facts to be ascertained. Determining res judicata and sub judice here would require examining pleadings, applications, rulings and orders in the alleged previous suits (Milimani CMCC No. E2062 of 2023 and ELC Appeal No. E09 of 2023), comparing records and probing evidence, which takes the matter outside the scope of a true preliminary objection.
Whether the suit and application are res judicata and sub judice, thereby ousting the Court's jurisdiction
The Court did not determine the merits of res judicata or sub judice; it held that these doctrines cannot be determined by way of the preliminary objection as framed
The Court held that determining whether the parties litigate under the same title, whether the issues are directly and substantially the same, and whether the matters were finally determined by a competent court cannot be resolved without probing evidence and comparing records from earlier proceedings. Such inquiry belongs at the substantive hearing or through a formal application supported by evidence, not a preliminary objection.
Legal principles established
#- A preliminary objection raises a pure point of law argued on the assumption that all facts pleaded by the other side are correct; it cannot be raised if any fact has to be ascertained or where the exercise of judicial discretion is sought
- A plea of res judicata or sub judice requiring comparison of pleadings, rulings and orders in prior suits is not a true preliminary objection because it entails factual ascertainment beyond the pleadings
Court orders

- 2.Costs of the Preliminary Objection awarded to the Plaintiff
- Jurisdiction invoked
