The bottom line
#A Kenyan court corrected arithmetic errors in a legal fees ruling, fixing the final bill at Kshs. 3,997,543, but refused to reopen settled items.
What this practically means
#Executive summary
#Key legal issues
#Whether there are arithmetical errors in the ruling of 10/07/2024 correctable under the slip rule
Yes - the final figure of Kshs. 3,969,626 was erroneous; certain contested items (23 & 36) were omitted from tabulation and uncontested/upheld items (totaling Kshs. 154,265) were also omitted. Paragraph 57 was reviewed and the bill taxed at Kshs. 3,997,543.
The court applied Sections 99 and 100 of the Civil Procedure Act and the Supreme Court's guidance in Outa v Okello, holding that corrections must reflect the court's original intention without changing the substance of the decision. It found the client's computation of the total was correct on the contested heads; found items 23 & 36 assessable at Kshs. 320 under Schedule 5 Part II paragraph 2; and found the taxing officer's awards on items not contested in the reference, and items upheld in the reference, had been mistakenly omitted from the final tabulation.
Whether the advocate could re-open items already determined in the impugned ruling
No - items assessed in the contested ruling (nos. 33, 34, 43, 37, 38, 40, 41, 42 and 43) contain no arithmetic error, and the court's jurisdiction on those matters is exhausted.
The court, as a court of record, re-examined the impugned ruling and agreed with the client that the items evaluated in the contested ruling, including the excess assessment of Kshs. 4,746, had been tabulated in the final calculation. Any grievance on those heads lies on appeal, not through a slip-rule application, which the court characterized as an attempt to appeal through the back door.
Legal principles established
#- The slip rule permits correction only of errors apparent on the face of the record that do not change the substance of the decision or the court's intention.
- Where a court has conclusively determined items in a ruling, it cannot re-open them under the slip rule; the only recourse is an appeal.
Court orders
#- 1.The ruling dated 10/07/2024 is reviewed and, in particular, paragraph 57, which is to read as the substituted text set out in the ruling (awarding Kshs. 4,000,000 instruction fees, retaining other items at Kshs. 154,265, applying 16% VAT, deducting the deposit of Kshs. 838,676.41, and taxing the bill at Kshs. 3,997,543)
