Joyce Wambui Mbau v Purity Wambui Wamwea & Others (Application by Kennedy Murigi Mbau)
The bottom line
#A Kenyan court revived a land suit filed by a now-deceased plaintiff, but the family must first pay the other side's legal costs.
What this practically means
#Executive summary
#Key legal issues
#Res judicata / abuse of process
The plea fails; none of the earlier applications conclusively determined the Applicant's right to substitution and revival, and the present application is the first to seek substitution and revival
The 11th November 2024 application sought reinstatement, not substitution or revival, and was dismissed for non-attendance, not on the merits. The Misc. Application E007 of 2025 was in a separate cause, whereas Order 24 applications must be made in the suit itself. The 22nd May 2025 application was withdrawn and never determined. The alleged 21st January 2025 application does not exist on the record; the certificates of urgency PWW 2 and PWW 3 relate to the same miscellaneous application.
Sufficient cause for extension of time and revival
Sufficient cause shown, though not without hesitation; COVID-19 explains part of the delay, the estate was not wholly inactive, and post-abatement lapses were largely those of former advocates
The court weighed the length of delay, explanation and prejudice. The pandemic explains delay to 2021 but not to July 2023. However, within eight months of the grant an administrator applied for substitution, and the Applicant filed an application on the very day the suit was declared abated. Counsel's errors should not be visited on the litigant. Prejudice to the Respondent is addressable by costs, while refusal would shut out the estate's land claim without a hearing.
Substitution of the Applicant
The Applicant has capacity to be substituted as Plaintiff, as administrator of the deceased Plaintiff's estate and administrator ad litem of Francis Mbau Murigi's estate; co-administrators to be served and at liberty to seek joinder
Order 24 Rule 3(1) requires the legal representative to be made a party, and Section 82(a) of the Law of Succession Act empowers personal representatives to enforce surviving causes of action. The grant of 11th July 2023 names the Applicant among three administrators. Although co-administrators did not join and one separately sought substitution, nothing suggests either opposes prosecution of the suit; the amended plaint shall be served on them.
Legal principles established
#- Abatement takes effect by operation of law; an abated suit ceases to exist in the eye of the law, and the operative relief is revival under Order 24 Rule 7(2)
- A dismissal for non-attendance or want of prosecution does not conclusively determine the rights of the parties and cannot found a plea of res judicata
- An application for substitution and revival under Order 24 must be made in the suit itself, not in a separate miscellaneous cause
- A blunder by counsel should not necessarily be visited on the litigant
