Key legal issues
#Whether the preliminary objection met the Mukisa Biscuit threshold
The objection partially raised pure points of law; the jurisdictional limb qualified as a proper preliminary objection while the sub judice limb involved mixed questions of law and fact
The court applied the Mukisa Biscuit and Oraro v Mbaja tests. It found that the claim that the court lacked jurisdiction because the High Court had already vested the property was a pure point of law. However, the res judicata and sub judice limbs required factual comparison of parties, pleadings and issues in two suits, making them mixed questions of law and fact which cannot properly be raised as a preliminary objection.
Whether the suit was res judicata
The suit is not barred by res judicata as the parties, issues and title litigated differ from Civil Suit No. 73 of 2005
Section 7 of the Civil Procedure Act requires identical parties litigating under the same title and issues directly and substantially determined. The EACC was not a party to the 2005 suit, which dealt solely with adverse possession. The present suit raises fraud, abuse of office and legality of acquisition of title, which go to the root of ownership and were never canvassed in the former proceedings.
Whether the suit was sub judice
Conditions for sub judice under Section 6 of the Civil Procedure Act were not satisfied
Section 6 requires a previously instituted suit between the same parties litigating under the same title with directly and substantially similar issues. Although the EACC had filed an application in the 2005 suit seeking to be enjoined, it was not yet formally a party, and the issues in the present suit (fraud, illegality of alienation of public land, abuse of office) are broader than the adverse possession question decided there. There is overlap in subject matter but parties and titles differ.
Whether the Environment and Land Court has jurisdiction over the suit
The Court has jurisdiction under Article 162(2)(b) and the Environment and Land Court Act, 2011
The plaintiff's claim concerns ownership of land, legality of acquisition of title, fraud and abuse of office - matters squarely within ELC jurisdiction. Although the ELC cannot sit on appeal over the High Court, this suit is not framed as an appeal but a fresh suit under Section 11(d) and (i) of the EACC Act empowering recovery or protection of public property. The issues were not canvassed in the 2005 suit, which dealt solely with adverse possession.
Legal principles established
#- A preliminary objection must raise 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
- Jurisdiction is everything; without it a court has no power to make one more step
- For res judicata to apply all five statutory conditions under Section 7 of the Civil Procedure Act must be satisfied conjunctively, including identity of parties and issues
- The Environment and Land Court has jurisdiction over disputes of land title, ownership, fraud and illegality of acquisition, and cannot sit on appeal over the High Court, but a fresh suit under statutory mandate is not an appeal

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.
That the Notice of Preliminary Objection raised by the 1st and 2nd Defendants herein dated 11th June, 2025 be and is hereby found to be without merit and hence dismissed in its entirety.
That the costs of the Notice of Preliminary Objection dated 11th June, 2025 shall be borne by the 1st and 2nd Defendants jointly and severally to be awarded .
That the Honourable Court holds that it is properly clothed with jurisdiction under the provision of Article 162 (2) (b) of the Constitution of Kenya, 2010 and Section 4 (2) of the Environment and Land Court, No. 19 of 2011 to hear and determine the present matter.
That the Honourable Court further finds that the Plaintifi, Ethics and Anti-Corruption Commission, was not a party to the former proceedings and therefore “The Doctrines of Res Judicata” and “Sub Judice” are inapplicable to the present suit.
Jurisdiction is everything. Without it, a Court has no power to make one more step.
A Preliminary Objection is in the nature of what used to be a demurrer. It raises a pure point of law which is argued on the assumption that all the facts pleaded by the other side are correct.
Issues in the judgment
#Date discrepancy: the court records delivery of the ruling as 13th February 2026 in the narrative but signs and dates it 12th February 2026
Internal inconsistency in dates: paragraph 3 and 10 refer to the plaintiff's application as dated 22nd July, 2025 while elsewhere it is described as dated 22nd May, 2025
