Sibabu Ali Mwamjibu v Valerine Achieng Opondo
The bottom line
#The Environment and Land Court in Kwale dismissed a landowner's attempt to stop a property dispute from going to trial, ruling that arguments based on disputed facts cannot be raised as preliminary objections.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether this Court has jurisdiction to determine this suit.
- 2.Whether the suit is sub judice.
Key legal issues
#Whether the ELC has jurisdiction over a suit alleged to concern division of matrimonial property
Objection overruled; the Matrimonial Property Act presupposes a marriage, which is neither pleaded nor undisputed, so the objection rests on disputed facts and is not a proper preliminary objection.
The court traced the Mukisa Biscuits threshold and held that a jurisdictional challenge is a pure point of law, but the application of the Matrimonial Property Act presupposes a marriage. Neither party pleaded marriage or that the property was a matrimonial home; the assertion was raised for the first time in the preliminary objection. Whether the parties were married is a question of fact requiring proof by evidence, disqualifying the objection.
Whether the suit is sub judice given the earlier KWALE CMELC No. 23 of 2024 suit
Objection fails; determining sub judice requires examining pleadings, parties, reliefs and status of the other suit, which are matters of fact outside a preliminary objection.
Section 6 of the Civil Procedure Act bars trial of a suit directly and substantially in issue in a previously instituted suit between the same parties. However, following Muchiri t/a Fancy Auctioneers and Margaret Wachu Karuri, the court must examine pleadings and material of the other suit to compare issues, parties and reliefs. The circumstances of the other suit's filing, dismissal and alleged withdrawal were disputed, and the material was insufficient for a conclusive determination.
Legal principles established
#- A preliminary objection must raise a pure point of law on undisputed facts; it cannot be raised where determination requires ascertainment of disputed facts.
- Jurisdiction is everything; a court without jurisdiction must down its tools.
- A sub judice objection cannot be determined on a preliminary objection where it requires examination of pleadings and material facts of the other suit.
Court orders
#- 1.The Defendant's Preliminary Objection dated 13th March 2026 is dismissed with costs.
The bench
#One judgment of the whole court — no separate or dissenting opinions.
Wrote the judgment
- Jurisdiction invoked
- Article 162(2) of the Constitution of Kenya and Section 13 of the Environment and Land Court Act No. 19 of 2011
Relief refused
#Preliminary objection on lack of jurisdiction (matrimonial property)
Founded on disputed facts; whether parties were married and whether the property is matrimonial property are questions of fact requiring evidence.
Preliminary objection on sub judice
Material before the Court insufficient; circumstances of the other suit's filing and withdrawal are disputed.
Costs
The Defendant's Preliminary Objection is dismissed with costs (costs to the Plaintiff).
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.
In the circumstances, the Defendant's objection to the jurisdiction of this Court is founded on disputed facts and does not constitute a proper preliminary objection. The objection on this ground is accordingly overruled
The Court finds that material before it is insufficient to enable it to conclusively determine the objection on the ground of sub judice. The objection therefore fails.
The upshot of the foregoing is that the Court finds that the Defendant's Preliminary Objection unmerited and is accordingly dismissed with costs.
Issues in the judgment
#Preliminary objection dated 13th March 2026 though suit filed April 2025 and ruling delivered September 2026; dates appear internally inconsistent with the case number year.
Judge's name printed ambiguously as 'Hon. E.G Nderitu L J'.
