The bottom line

#

A Kenyan court refused to re-open a decided land case, holding that once it delivers final judgment it loses power to change its own decision.

What this practically means

#

Executive summary

#
The defendant filed a notice of motion dated 29th June 2026 seeking a declaration that the suit was null and void ab initio as res judicata, setting aside of the judgment and decree in the suit, and costs. She contended that the plaintiff had previously filed Kehancha SPM ELC Case No. E012 of 2022 between the same parties over the same subject matter, which was heard and determined in her favour on 25th March 2025, and that the present suit and its conflicting judgment amounted to res judicata. The plaintiff opposed, asserting the earlier suit was struck out as fatally incompetent and never determined on merits, so res judicata could not arise; further, that the defendant had raised res judicata as a preliminary objection in her defence but withdrew it and participated in the full hearing, and the issue could not be re-litigated by application. Before addressing res judicata, the court examined its own jurisdiction after judgment, applying the functus officio doctrine as articulated in Telkom Kenya v John Ochanda, Mohmed Dagane Falir, and Dickson Muricho Muriuki. Noting that its judgment of 17th June 2026 had not been varied, set aside or appealed, the court held it was functus officio and could not re-open the case to reach a different decision. The application was dismissed with costs to the plaintiff. Leave to appeal was granted.

Questions the Court framed

  1. 1.Whether the Court is functus officio after delivery of judgment on merits, having regard to the defendant's withdrawal of her preliminary objection on res judicata

Key legal issues

01

Functus officio after judgment on merits

Holding

The Court held it was functus officio and could not entertain an application to re-open the decided suit via res judicata

Reasoning

The suit had been heard and determined by judgment delivered on 17th June 2026. The defendant had abandoned her preliminary objection on res judicata and had not appealed. Applying Telkom Kenya and Dickson Muricho Muriuki, the court found the functus officio doctrine barred it from revisiting the judgment, and dismissed the application with costs.
