Peter Kabui Mwangi v Roseline Njeri Muriuki & 8 Others
The bottom line
#A Kenyan court dismissed a client's attempt to avoid paying his former lawyer's taxed fees, confirming that a retainer can be proven by conduct and payment records.
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 Applicant's Notice of Motion is incompetent and procedurally defective for non-compliance with the provisions of Paragraph 11 of the Advocates Remuneration Order.
- 2.Whether a retainer relationship existed between the Applicant the 3rd Defendant and the Respondent Advocate/law firm.
- 3.Whether the Applicant has satisfied the requisite legal standards for an extension of time to file a Reference out of time and for setting aside the Taxation Ruling dated 11th October 2023, the Certificate of Taxation, and the consequential execution processes.
Key legal issues
#Procedural competence of the Notice of Motion versus a Reference under Paragraph 11 of the Advocates Remuneration Order
The Motion was competent; the specific-procedure rule yields to Article 159(2)(d) where the deviation goes to no jurisdiction or prejudice
The court accepted that a specific statutory procedure should ordinarily be followed, but held that where the Applicant alleges total lack of notice, fraud and absence of retainer, approaching the court by Notice of Motion does not divest it of jurisdiction. Citing Salat, Wachira Karani and Boniface Kiragu Waweru, it held that lapses not going to jurisdiction or causing no prejudice should not attract draconian consequences, and substantive merit should be interrogated.
Existence of an Advocate-client retainer
A retainer existed; the Applicant is estopped from denying he instructed the Respondent
Applying Omulele & Tollo and Ochieng' Onyango, the court found mobile money transfers of Kes 20,000 and Kes 5,000, email transmission of a signed Replying Affidavit, a filed Notice of Appearance and secured status quo orders. Most decisively, the incoming firm Prof. Kiama & Co. served a Notice of Change of Advocates under Order 9 Rule 9 on the Respondent firm, which defeats the claim of non-representation.
Extension of time and setting aside the taxation Ruling, Certificate of Taxation and execution processes
Refused; the Salat conditions were not met and no error of principle by the Taxing Master was shown
Service of the bill by email on 19/04/2023 was proved. The Applicant, having been properly seized of the suit and having instructed incoming counsel who served a Notice of Change, turned a blind eye to the proceedings. The taxation was conducted to scale under the Advocates Remuneration Order, 2014, and under First American Bank v Shah no interference lies absent a wrong principle or manifest excess.
Legal principles established
#- A retainer need not be written; it can be oral or inferred from conduct, but if only the Advocate's statement supports it and the client contradicts it, the Advocate is treated as acting without authority
- A court will not interfere with a Taxing Officer's decision unless a wrong principle is shown or the fee is manifestly excessive or inadequate
- Extension of time is an equitable discretionary remedy governed by the Salat parameters, including plausibility of the reason for delay and prejudice to the respondent
Court orders
#- 1.The Applicant's Notice of Motion dated 19/05/2025 be and is hereby dismissed in its entirety.
- 2.The interim orders of stay of execution, if any, granted pending the hearing and determination of this application be and are hereby vacated forthwith.
- 3.The Respondent Law Firm (M/s Wafula Washika & Associates / John Simiyu Wanyonyi Advocates) is granted leave to proceed with execution enforcement processes pursuant to the Ruling dated 11/10/2023 and the Certificate of Taxation dated 30/04/2025.
- 4.The costs of this Application are awarded to the Respondent law firm.
- 5.File Closed.
The bench
#One judgment of the whole court — no separate or dissenting opinions.
Wrote the judgment
- Jurisdiction invoked
- Article 159(2) of the Constitution of Kenya, 2010 (inherent powers of the court) and all enabling provisions of the law
Relief refused
#Stay of execution of certificate of taxation, warrant of attachment, warrant of sale and proclamation
Application devoid of merit; retainer established and Applicant failed to show error of principle by the Taxing Master
Declaration that the Advocate-Client Bill of Costs proceedings, Ruling and certificate of taxation are a nullity
Fraud and non-retainer allegations wholly unsubstantiated and contradicted by documentary evidence
Enlargement of time to file a Reference against the Taxing Master's decision
Delay unexplained; Applicant turned a blind eye to proceedings after proper service
Striking out of the Advocate-Client Bill of Costs for fraud
No evidence of fraud; retainer proved by mobile money records, emails and Notice of Appearance
Costs
The costs of this Application are awarded to the Respondent law firm.
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.
i) That the Applicant's Notice of Motion Application dated 19/05/2025 be and is hereby dismissed in its entirety.
That the interim orders of stay of execution, if any, granted pending the hearing and determination of this application be and are hereby vacated forthwith.
That the Respondent Law Firm (M/s Wafula Washika & Associates / John Simiyu Wanyonyi Advocates) is hereby granted leave to proceed with execution enforcement processes pursuant to the Ruling dated 11/10/2023 and the Certificate of Taxation dated 30/04/2025.
It defeats legal logic for an incoming Advocate to serve a Notice of Change of Advocates pursuant to Order 9 Rule 9 upon a law firm that allegedly never represented the client in the first instance.
That the costs of this Application are awarded to the Respondent law firm.
