Outa v Okello & 3 others
The bottom line
#Supreme Court dismisses bid to revoke costs certificate over name error, calling it frivolous.
What this practically means
#The Supreme Court dismissed an application to revoke a certificate of costs because the certificate correctly used the name from the original judgment. The applicant argued that an earlier bill of costs had a wrong name, but the court said that was a minor slip that did not affect the final certificate. The court found the application lacked merit and was made in bad faith, ordering the applicant to pay the other side's legal costs.
Executive summary
#Key legal issues
#Whether the court has jurisdiction to entertain an application to revoke a certificate of costs after a single Judge's decision on a reference on taxation, which is final under rule 62(2) of the Supreme Court Rules.
The court did not directly rule on the jurisdictional objection but dismissed the application on its merits, finding it frivolous and vexatious.
The appellant argued that under rule 62(2) the decision of a single Judge on a reference on taxation is final, so the court lacks jurisdiction. However, the court did not address this point explicitly; instead, it found the application lacked substance and was made in bad faith, and dismissed it on that basis.
Whether the certificate of costs should be revoked or corrected due to an alleged error in the name of the 1st respondent.
The certificate of costs correctly named the 1st respondent as Jared Odoyo Okello, reflecting the judgment of the court, and the application to revoke or correct it was dismissed as frivolous.
The court noted that the judgment of July 3, 2014, named the 1st respondent as Jared Odoyo Okello. The appellant's bill of costs inadvertently used the name 'Jared Otieno Odoto', but the final certificate correctly used the name from the judgment. The court characterized this as a slip rule matter and found the application lacked substance.
Legal principles established
#- A certificate of costs that matches the judgment's party name is valid even if an earlier bill had a typo.
- An error in a bill of costs that does not carry into the final certificate is a slip rule issue, not grounds for revocation.
- Courts can dismiss an application as frivolous and vexatious without first deciding on jurisdictional objections.
- The final certificate of costs is the conclusive record of the court's decision on costs.
Court orders
#- 1.The motion dated November 24, 2023 be and is hereby dismissed

Key timeline
#Practical implications
#Challenge costs certificates carefully
When challenging a certificate of costs, ensure the error is in the final certificate, not just in an earlier bill. The court will treat minor name discrepancies as slip rule matters. Also, filing a motion that appears baseless may be dismissed as frivolous, with adverse costs orders. Consider jurisdictional limits under rule 62(2) before bringing such applications.
Costs orders are final once certified
If you are awarded costs in litigation, the final certificate of costs is binding. Opponents cannot easily revoke it based on minor errors in earlier documents. This ruling reinforces that once a certificate is issued matching the judgment, it is stable. Businesses should ensure their legal teams verify names and details early to avoid unnecessary disputes.
Name errors in court papers
If your name is misspelled in a bill of costs but the final certificate uses the correct name from the judgment, you cannot use that error to cancel the certificate. The court sees this as a simple slip. To avoid confusion, always check that your name is correct in all court documents from the start. If an error occurs, ask for a correction early rather than waiting.
Frequently asked questions
#Can a certificate of costs be revoked in Kenya?+
Only if the certificate itself contains a material error that does not reflect the court's judgment. Minor mistakes in earlier bills, like a name typo that is corrected in the final certificate, are not grounds for revocation. The court will dismiss such applications as frivolous.
What is the slip rule in Kenyan courts?+
The slip rule allows a court to correct accidental mistakes or omissions in its judgments or orders. In this case, a wrong name in a bill of costs was considered a slip that did not affect the final certificate. The rule prevents parties from using minor errors to undo valid court decisions.
How to correct an error in a bill of costs in Kenya?+
If the error is in the bill of costs but not in the final certificate, you may not need to do anything. If the final certificate has an error, you can apply to the court for correction under the slip rule. Act promptly and show that the mistake is accidental and does not change the substance of the decision.
What happens if a party's name is wrong in a court document in Kenya?+
If the error is minor and the correct identity is clear, the court may treat it as a slip and allow correction. However, if the error is in a final document like a certificate of costs, you must apply for correction. The court will not revoke the entire document unless the error is fundamental.
