Housing Finance v Kihiu (Civil Appeal 202 of 2019) [2026] KECA 408 (KLR)
The bottom line
#Kenya's Court of Appeal ruled that a borrower's new claim over loan overpayments could proceed despite an earlier case over the same loan.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the cause of action in the second suit (CMCC No. 2691 of 2013) arose after the first suit had been finalized such that it could not have been raised in the earlier suit, thereby excluding res judicata
- 2.Whether the learned judge erred in finding that there were special circumstances to exclude the application of res judicata
- 3.Whether the learned judge failed to exercise her discretion judiciously by failing to consider the submissions and authorities placed before her
Key legal issues
#Whether res judicata under section 7 of the Civil Procedure Act bars a second suit founded on a cause of action that arose after the first suit was determined
It does not. The court affirmed the High Court's finding that the respondent's claim of overpayment crystallising on discharge of charge in February 2012, about six months after the first suit's determination, could not have been raised in the former suit.
The court held that despite the same parties, loan contract and security, the decisive question is whether the second suit's cause of action arose after the first suit's finalization. The respondent alleged overpayment of about Kshs.1.3 million as at discharge of the security in February 2012, six months after the first judgment, and the borrower-lender relationship continued after that suit. Following Housing Finance v J. N. Wafubwa, post-determination developments bring the matter within the Henderson 'special case' exception.
Whether the existence of a new cause of action can be determined on a preliminary objection
No; it involves contested facts requiring evidence and is not amenable to determination as a demurrer.
There was contestation as to the nature and character of the supposed new cause of action and whether it in fact arose after determination of the first suit. Because the controversy involved matters of fact as well as law, resolution required evidence rather than a preliminary objection. The magistrate's ruling upholding res judicata as a preliminary matter was therefore unsustainable.
Whether the High Court erred in finding special circumstances excluding res judicata
The respondent conceded the special-circumstances framing was a misdirection, but the court held the ultimate finding that res judicata did not apply was sound and unaffected.
The respondent conceded the High Court misdirected itself in treating the case as one of special circumstances under Henderson, whereas its argument was that res judicata did not apply at all. The Court of Appeal nonetheless found the outcome correct because the new-cause-of-action analysis independently justified the result, aligning with Wafubwa where post-determination developments constituted special circumstances.
Legal principles established
#- The decisive test for res judicata is whether there is a new cause of action arising after the determination of the first suit which could not, with reasonable diligence, have been raised in it; same parties, contract or security do not by themselves attract the doctrine.
- Whether a supposed new cause of action arose after determination of the first suit is a question of contested fact requiring evidence, and is not a proper matter for resolution on a preliminary objection.
- Developments occurring after the institution and determination of a former suit constitute special circumstances bringing a subsequent suit within the exception to the doctrine of res judicata.

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.
Ultimately, we are unable to find fault in the decision of the High Court and uphold it. The appeal is dismissed in its entirety with costs.
The decisive factor is whether there was a new cause of action which arose after the determination of the first suit which could not have possibly been raised and agitated, notwithstanding all diligence, in the first suit.
those would need to be proved by evidence and were not proper matters to be resolved as a preliminary demurrer. The controversy did not just involve a matter of law but contested facts.
The plea of res judicata applies, except in special cases, not only to points upon which the Court was actually required by the parties to form an opinion and pronounce a judgment, but to every point which properly belonged to the subject of litigation
Issues in the judgment
#The judgment states different figures for the alleged overpayment: the plaint reference is Kshs.1,314,148.10 while the narrative of the second suit records Kshs.1,304,148.10
