Mwarabu & another v Kariuki t/a BG Kariuki & Company Advocates (Environment and Land Miscellaneous (Reference) Application E025 of 2024) [2025] KEELC 4047 (KLR)
The bottom line
#A Kenyan court threw out a lawyer's bill because the taxing officer used a mechanical formula instead of properly assessing each disputed item.
What this practically means
#Executive summary
#Key legal issues
#Whether the taxing officer erred by applying a mechanical formula of party and party costs plus 50% in taxing the advocate/client bill
The taxing officer misapprehended the principles applicable in taxation of an advocate/client bill by treating the enhancement as an entitlement as of right requiring no discretion, and her ruling was accordingly erroneous and set aside
The taxing officer relied on Central Bank of Kenya v Makhecha to hold that once party and party costs are taxed, the advocate is entitled as of right to those costs plus half, as a matter of arithmetic requiring no discretion. The court, guided by the Supreme Court's decision in Kenya Airports Authority v Otieno Ragot, held that Schedule VI Part B requires judicious evaluation of disputed items guided by the Part A scale, not a mere mathematical formula, and failure to evaluate disputed items is contrary to the Advocates Remuneration Order.
The principles on which a court may interfere with a taxing officer's decision
A court cannot interfere with a taxing officer's decision unless it is shown that the decision was based on an error of principle or that the fee awarded was manifestly excessive
The court restated the classic threshold for interference on a reference from taxation. Applying that threshold, the taxing officer's purely arithmetic approach constituted an error of principle warranting the court's intervention, since she failed to exercise the judicial discretion required in assessing instruction fees where items are disputed.
Legal principles established
#- A taxing officer assessing instruction fees under Schedule VI Part B of the Advocates Remuneration Order must exercise discretion guided by the prescribed scale of fees in Part A and is not confined to a mechanical 50% enhancement of party and party costs.
