The bottom line

#

A Kajiado court ruled that res judicata cannot be used to kill a land suit through a preliminary objection because comparing court records requires evidence.

What this practically means

#

Executive summary

#
This ruling of the Environment and Land Court at Kajiado (M.D. Mwangi J) determined a Notice of Preliminary Objection dated 16th December 2025 filed by the 10th Defendant/Respondent against the hearing of the Plaintiff/Applicant's application dated 23rd September 2025 and an Originating Summons of even date. The 10th Respondent contended that the suit was res judicata by virtue of High Court Petition No. 105 of 2010. The objection was canvassed by written submissions. The court framed a single issue: whether the plea of res judicata is properly raised by way of a preliminary objection. Relying on the classic exposition in Mukisa Biscuit Manufacturing Co. Ltd v West End Distributors Ltd (1969) EA 696, the court reiterated that a preliminary objection must be a pure point of law argued on the assumption that all facts pleaded by the other side are correct, and cannot be raised where facts must be ascertained. Adopting the High Court's reasoning in Henry Wanyama Khaemba v Standard Chartered Bank Limited & Another [2014] eKLR, the court held that determining res judicata under Section 7 of the Civil Procedure Act requires interrogating the record of the earlier suit - its pleadings, parties, issues and finality - which are evidentiary matters outside the limited jurisdiction exercised on a preliminary objection. The court directed that the plea be raised through an appropriate substantive application. The objection was found not to disclose a pure point of law, was held devoid of merit, and was dismissed with costs. The suit itself was not terminated and proceeds to substantive hearing.

Key legal issues

01

Whether res judicata may properly be raised by way of a preliminary objection

Holding

No - the plea of res judicata requires a factual inquiry into the earlier suit and therefore does not amount to a pure point of law; it must be raised through a substantive application

Reasoning

Applying Mukisa Biscuit and Henry Wanyama Khaemba, the court reasoned that determining res judicata under Section 7 of the Civil Procedure Act requires examining the pleadings, parties, issues and finality of the earlier suit and comparing them with the present proceedings. Those are evidentiary matters falling outside the limited scope of a preliminary objection, which assumes all facts pleaded by the other side are correct.
