John Mbau Mburu t/a J.M. Mburu & Company Advocates v County Government of Mombasa & Robinson Onyango Malombo t/a O. M. Robinson & Company Advocates
The bottom line
#Kenya's Court of Appeal confirmed it cannot amend pleadings already decided by the High Court, so the advocate's Kshs. 102 million claim collapsed.
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 single Judge correctly concluded that he lacked jurisdiction to amend the Petition that had been filed, heard, and determined in the High Court
- 2.Whether the single Judge properly declined to enter judgment on admission for Kshs. 102 million in the absence of any enabling provision, and bearing in mind that granting such relief would have the effect of conclusively determining the entire appeal
Key legal issues
#Whether the Court of Appeal can amend pleadings originating in the High Court
It cannot. Pleadings are primary documents and, although rule 46 speaks of amending 'any document', that phrase must be construed restrictively so as not to defeat rule 85(2A). Amending trial pleadings would place new matters never considered by the High Court before the appellate court.
The Court relied on its settled jurisprudence classifying pleadings as primary documents that cannot be brought into or altered on the record of appeal by supplementary means. Permitting amendment of a High Court petition would transform the appellate court into a trial court, undermine the appellate process which relies on the record as it transpired below, and allow new causes of action on appeal.
Whether judgment on admission for Kshs. 102 million could be entered by a single Judge
No. The prayer fell with the amendment; no rule of court authorized the Court, let alone a single Judge, to enter judgment on admission; and such an order would finally determine the appeal, a power reserved for the full bench.
The Court identified three independent grounds: the amendment having failed, the claim for Kshs. 102 million (reframed as special damages) had no legal foundation; no enabling provision was cited; and entering judgment would 'settle the appeal' in chambers, exceeding the powers of a single Judge.
The threshold for interfering with a single Judge's decision on a reference to the full Court
A reference is not an appeal. The Applicant must show irrelevant considerations were taken into account, a relevant matter ignored, misapprehension of law or evidence, or a plainly wrong decision; it is not enough that the full Court might have decided differently.
Applying Hezekiah Michoki v Elizaphan Onyancha Ombongi, John Koyi Waluke v Moses Masika Wetangula and Simeon Okingo & 4 others v Benta Juma Nyakako, the Court found the Applicant had demonstrated no misdirection, no ignored relevant factor, no irrelevant consideration, and no plainly wrong decision, so the Rule 55 threshold was not met.
Legal principles established
#- An appellate court has no jurisdiction to amend pleadings (primary documents) filed, heard and determined in the trial court; to do so would turn the appellate court into a trial court.
- A reference to the full Court under Rule 55 is not an appeal; the full Court may only interfere with a single Judge's exercise of discretion where irrelevant considerations were taken into account, a relevant matter was ignored, the law or evidence was misapprehended, or the decision is plainly wrong.
- The phrase 'any document' in rule 46 must be construed restrictively; primary documents such as pleadings cannot be amended on appeal.
- A single Judge sitting in chambers cannot enter judgment that would conclusively determine an entire appeal; that power is reserved for the full bench.
Court orders
#- 1.The reference brought by way of the letter dated 28th January 2025 is dismissed
- 2.Costs of the reference awarded to the Interested Party
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- Court of Appeal of Kenya (decision of a single Judge, Korir, JA.)
- Application dated 23rd August 2024 in pending appeal from High Court Petition No. 4 of 2019
- Jurisdiction invoked
- Rule 55(1)(b) of the Court of Appeal Rules (reference to the full Court from a decision of a single Judge)
Relief refused
#Interference with the single Judge's ruling denying leave to amend the High Court Petition
Pleadings filed in the High Court are primary documents that cannot be amended by the Court of Appeal; the Applicant failed to meet the Rule 55 threshold for interference with a single Judge's discretion
Entry of judgment on admission for Kshs. 102 million
The prayer was premised on the rejected amendment, no rule authorized entry of judgment on admission, and it would have finally determined the entire appeal
Costs
The reference was dismissed with costs to the Interested Party only; the Court's order reads: 'the reference brought by way of the letter dated 28th January 2025 lacks merit and is hereby dismissed with costs to the Interested Party.' (The single Judge's ruling below had dismissed the Notice of Motion with costs to both the Respondent and the Interested Party.)
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.
In light of these authorities and statutory provisions, it is beyond dispute that pleadings filed in the High Court—being primary documents—cannot be amended by this Court.
In sum, the reference brought by way of the letter dated 28th January 2025 lacks merit and is hereby dismissed with costs to the Interested Party. It is so ordered.
a full bench of the Court may only interfere with the exercise of discretion by a single judge if it is demonstrated that the Judge took into account irrelevant considerations which ought not to have been taken into account, or failed to consider a relevant matter that ought to have been considered, or if the judge misapprehended the applicable law or the evidence before them, or ultimately reached a decision that is plainly wrong.
Whilst it is true that rule 44 (current rule 46) speaks of an amendment of any document it must necessarily be construed in the light of rule 85(2A) which was brought in by way of an amendment in 1990.
Issues in the judgment
#The judgment states the Applicant filed a constitutional petition before the High Court after being aggrieved, but then records a 'Judgment delivered on 20th December 2018' dismissing the petition, while the application before the single Judge is dated 23rd August 2024 - the chronology as narrated places the aggrieving event after the judgment; apparent internal inconsistency in dates.
