The bottom line
#You cannot sue again over a matter already decided by a Kenyan court unless you first file a fresh suit proving the original judgment was obtained by fraud.
What this practically means
#Executive summary
#Key legal issues
#Whether a res judicata objection is properly raised as a preliminary objection
Yes; res judicata is a point of law, capable of disposing of the suit summarily, with no contest as to facts, so the objection satisfies the Mukisa Biscuits criteria
Applying Mukisa Biscuit Manufacturing Co Ltd v West End Distributors and Aviation & Allied Workers Union v Kenya Airways, the court distilled three ingredients: a pure point of law, capability of disposing of the suit summarily, and no contest as to facts. It found res judicata is a point of law, would dispose of the suit summarily if upheld, and the parties did not contest the underlying facts. The objection therefore 'ticks all the boxes'.
Whether a judgment alleged to have been fraudulently obtained defeats a plea of res judicata
Fraud is an exception to res judicata, but the alleged fraud must first be established in a fresh suit to set aside the judgment; until then the judgment binds the parties
Relying on Outa v Okello (Supreme Court) and Steyn v Ruscone, the court accepted that finality may be departed from where a judgment was obtained by fraud. However, the instant plaint did not plead or seek a declaration of fraud; it replicated the former suit. A court cannot try a matter already decided by a court of competent jurisdiction while the judgment stands; doing so would amount to sitting on appeal over the magistrates' court's own judgment.
Whether the instant suit is res judicata Bungoma CMC CC. No. E351 of 2023
Yes; all the conjunctive elements of section 7 of the Civil Procedure Act were satisfied or undisputed
The parties did not dispute that the issues were the same, the former suit was between the same parties litigating under the same title, the issues were finally determined by judgment on 17th July 2024, and the former court (Hon. Maundu) was competent. The only dispute was the alleged fraudulent procurement of the former judgment, which the court held could not excuse a duplicate suit absent a fresh suit to set that judgment aside.
Legal principles established
#- 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 if any fact has to be ascertained
- All elements of section 7 of the Civil Procedure Act must be satisfied conjunctively for res judicata to be successfully invoked
- A fraudulently obtained judgment is an exception to the doctrine of res judicata, and such a judgment can only be set aside through a fresh suit invoking section 47 of the Evidence Act and the court's inherent powers
Court orders
#- 1.The Defendant/Applicant's Notice of Preliminary Objection dated 10th November 2025 is upheld as merited
- 2.This suit is dismissed with costs of Kshs. 40,000/=
- 3.The file is closed
- Jurisdiction invoked
- Original civil jurisdiction of the magistrates' court; objection grounded on section 7 of the Civil Procedure Act
