#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the learned Judge erred in holding that the Chamber Summons dated 15 December 2017 was not barred by res judicata
- 2.Whether the discharge voucher constituted a valid retainer agreement under section 45 of the Advocates Act capable of barring taxation of the bills of costs
Key legal issues
#Whether the Chamber Summons dated 15 December 2017 was barred by res judicata
It was not. The earlier Deputy Registrar rulings dealt with a preliminary objection on jurisdiction under section 48 and a joinder application, neither of which finally determined the validity of the retainer agreement or discharge voucher; the joinder ruling was also made without jurisdiction and thus a nullity.
The court applied the four elements of res judicata, including a prior final determination by a competent court. The 14 February 2012 ruling was confined to a preliminary objection under section 48 of the Advocates Act and did not address any retainer or discharge voucher. The 27 July 2012 joinder ruling was set aside on appeal by Okwany J, who held the Deputy Registrar lacked jurisdiction; a decision without jurisdiction is a nullity and cannot ground res judicata. The validity of a retainer agreement could only be decided by a High Court Judge.
Whether the discharge voucher of 26 April 2008 was a valid agreement barring taxation
Yes. The voucher was signed by the same partner who executed the 2003 retainer agreement, had ostensible authority, and bound the firm; any internal complaint lay against that partner, not the client.
It was common ground that a retainer agreement dated 28 March 2003 was signed on behalf of the firm by Hon. George Omweri Nyamweya, the same partner who signed the discharge voucher accepting Kshs.800,000 in full discharge of fees. The respondent dealt with a partner with ostensible authority; if the firm was dissatisfied with how the voucher was executed, its remedy lay in suing the partner. The firm is bound and cannot resile.
Whether a settlement below the Advocates (Remuneration) Order minimum vitiates the discharge voucher
No. Following Njogu & Company Advocates v National Bank of Kenya Ltd, an advocate who knowingly agrees fees contrary to the Remuneration Order cannot later avoid that agreement by reverting to taxation; he is estopped by his conduct.
The Court adopted the reasoning in Njogu that an advocate who willingly and knowingly enters an agreement on fees contrary to the Remuneration Order cannot maintain proceedings to avoid the illegal agreement by taxing a client-advocate bill. The appellant, having made its bed, must lie on it; the bill of costs was properly struck out.
Legal principles established
#- A decision rendered by a forum without jurisdiction is a nullity and cannot ground a plea of res judicata
- Only retainer or fee agreements compliant with section 45 of the Advocates Act can bar taxation of a bill of costs, and such agreements are construed strictly
- An advocate or law firm that signs a discharge voucher settling its fees is bound by it and cannot resile from it or revert to taxation, even if the agreed amount fell below the Remuneration Order
- Whether a fee agreed in a discharge voucher accords with the Advocates (Remuneration) Order is not a ground for avoiding the voucher; the advocate is estopped by conduct

Relief refused
#Appellants' plea that the Chamber Summons of 15 December 2017 was res judicata by reason of the Deputy Registrar's rulings of 14 February 2012 and 27 July 2012
The earlier rulings concerned distinct questions (a preliminary objection and a joinder application) and the latter was made without jurisdiction, so could not ground res judicata
Declaration that the discharge voucher was null and void for want of capacity, illegality and breach of the Advocates Act and Remuneration Order
The respondent dealt with a partner with ostensible authority; the firm is bound by the voucher and cannot resile from it
Costs
The appeal is dismissed with costs to the respondent
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.
It is clear from the foregoing that the appeal lacks merit and is hereby dismissed with costs.
We hold that once the law firm agreed accepted to e paid the said sum of Kshs.800,000/= and signed the discharge voucher, it was bound by the terms of the said discharge voucher.
The appellant cannot in the circumstances resile from the retainer agreement. We cannot fault the trial court for upholding the retainer agreement.
jurisdiction is everything; a decision rendered without it is a nullity and cannot ground a plea of res judicata
There was no error in the High Court's holding that the application was not res judicata.
This Court in Ahmednasir Abdikadir & Co. Advocates v National Bank of Kenya Ltd [2006] eKLR held that only agreements compliant with section 45 can bar taxation.
Issues in the judgment
#Spelling inconsistency in the judgment text: the discharge voucher signatory is rendered 'George Omari Nyamweya' in earlier paragraphs and 'George Omweri Nyamweya' in later paragraphs of the same judgment
Typographical errors in the judgment text ('accepted to e paid', 'ofiends', 'afirmed') suggest OCR corruption of the certified copy
