The bottom line

What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether an application for joinder is legally tenable post-judgement
- 2.Whether the judgment delivered on 28th September 2023 and decree issued on 15th March 2024 should be set aside on account of material non-disclosure and misrepresentation of facts
- 3.Whether a stay of execution restraining the Plaintiffs from executing the judgment and decree should issue
- 4.Whether the applicants should be granted leave to file their pleadings and the suit be re-tried
Key legal issues
#Whether joinder of a party is permissible post-judgment
It is not; joinder under Order 1 rule 10(2) applies only to pending proceedings, and a concluded suit leaves nothing to which a party may be joined
The court noted that judgment was delivered on 28th September 2023 and there were no pending proceedings into which the applicants could be joined. Relying on Order 1 rule 10(2) and the decisions in JMK v MWM, Tang Gas Distributors, Kimwele v Kubora and Everton Coal Enterprises, the court held that joinder is only available in pending proceedings and that once a suit is finally disposed of the rule becomes inapplicable.
Whether the judgment should be set aside for material non-disclosure and misrepresentation
The prayer failed as a consequence of the failure of the joinder prayer
The court framed all subsequent prayers as dependent on the joinder prayer. Having found the joinder untenable in law post-judgment, the court held the subsequent prayers - stay of execution, setting aside, re-trial and leave to file pleadings - failed as a matter of course, advising the applicants to rethink their litigation strategy.
Legal principles established
#- An application for joinder of parties can be filed only in pending proceedings; where a suit has been finally disposed of and there is nothing more to be done, the joinder rule becomes inapplicable
- A court is functus officio regarding joinder once a matter has been heard, concluded and judgment rendered
Court orders
#- 1.The Notice of Motion dated 29th September, 2025 is dismissed with costs to the Plaintiffs

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.
Guided by the provisions of Order 1 rule 10(2) of the Civil Procedure Rules, and the above cited binding and persuasive decisions, the court finds and holds that the application by the proposed interested parties to be joined into this suit, post- judgement, is untenable in law; it is incompetent and without legal basis. It must therefore fail.
The upshot is that the Notice of Motion dated 29th September, 2025 is hereby dismissed with costs to the Plaintifis.
it is only when a suit or proceeding has been finally disposed of and there is nothing more to be done that the rule becomes inapplicable.
Order 1 rule 10(2) of the Civil Procedure Rules allows for joinder, only during ongoing proceedings.
Issues in the judgment
#Date discrepancy: the reliefs sought refer to a judgment 'dated 28th September, 2023' while the application is described as 'post-judgement' and the ruling is dated April 2026; the motion is dated 29th September 2025, nearly two years after judgment
Header describes the application as by 'the 1st to 8th Proposed Interested Parties' while the body describes nine (9) proposed Interested Parties
Grounds of opposition dated 15th December, 2025 appear inconsistently dated relative to the application of 29th September 2025 and ruling of 23rd April 2026
