Key legal issues
#Assessment of general damages for pain, suffering and loss of amenities
Awarded Ksh. 3,500,000/=, guided by comparable injuries, the age of the cited awards and inflation
The court compared the plaintiff's injuries (left brachial plexus root avulsion with paralysis of the left upper limb) with awards in Mwaura Muiruri, Beatrice Khamede and Simon Taveta. Considering the age of those awards and inflation, Ksh. 3,500,000/= was found sufficient. Liability had already been apportioned 90:10 by consent.
Conflicting medical assessments of permanent disability (65% vs 25%)
Preferred the assessment of 65% by Dr. Wokabi, who used the WIBA scale, over Dr. Wambugu's 25%
Dr. Wambugu relied on the Schedule to the Insurance (Motor Vehicle Third Party Risks) Act, which the court found provides a structured compensation liability schedule rather than a guideline for assessing permanent disability, making his basis wrong. The WIBA scale provides better guidance, though the court noted the plaintiff had improved.
Loss of earning capacity - method and quantum
Ksh. 1,000,000/= awarded as a global sum, not on a multiplier basis
Following William J Butler, Mumias Sugar and S J v Francesco Di Nello, the court held that loss of earning capacity differs from loss of future earnings and cannot be mathematically calculated. Comparing authorities where disability was 40%, 15%-50% and 20%-65%, and given the plaintiff's disability of 20%-65%, Ksh. 1,000,000/= was awarded.
Loss of earnings - proof
Claim dismissed; special damages not proved
Loss of earnings is a special damage that must be specifically pleaded and strictly proved (Kibet v Alunda; Douglas Kalafa Ombeva; Cecilia W. Mwangi). Apart from mere testimony that she earned Ksh. 1,000/= per day hairdressing and Ksh. 3,000/= per day from a hotel, the plaintiff produced no documentary proof, and she conceded in cross-examination that she did not own the salon.
Cost of hiring a domestic help
Claim dismissed for failure to plead and strictly prove the amount
The plaint did not plead how much the plaintiff paid or would pay the house help; the Ksh. 7,000/= per month figure emerged only in testimony with no documentary support. Relying on Salim S. Zein and other authorities, the court held such claims are special damages requiring strict proof.
Interest on damages
Interest on general damages from date of judgment; interest on special damages from date of filing suit; no interest on loss of earning capacity
Guided by section 26 of the Civil Procedure Act and the authorities on interest, the court held that special damages are ascertainable from the date of loss while general damages are only ascertained at judgment. No interest is recoverable on loss of earning capacity.
Legal principles established
#- Loss of earning capacity is distinct from loss of earnings: the former is general damages proved on a balance of probabilities, the latter is special damages which must be specifically pleaded and strictly proved
- The multiplier approach is inappropriate for loss of earning capacity; a global sum approach is the appropriate method
- Claims for the hire of domestic help and future care are in the nature of special damages which must be specifically pleaded and strictly proved
- Special damages must be specifically pleaded and strictly proved
- Interest on special damages runs from the date of loss/filing of suit, while interest on general damages runs from the date of judgment
- Assessment of general damages is a discretionary exercise guided by comparable awards, inflation and moderation

The bench
#One judgment of the whole court — no separate or dissenting opinions.
Wrote the judgment
- Jurisdiction invoked
- Original civil jurisdiction of the magistrates' court over a road traffic accident (negligence) claim
Relief refused
#Loss of earnings (claimed at Ksh. 4,368,000/=)
The claim is in the nature of special damages and, apart from mere testimony, the plaintiff produced no documents to prove her earnings
Cost of hiring a domestic help (claimed at Ksh. 1,680,000/=)
The claim is in the nature of special damages; no documentary evidence was adduced to confirm the payment of Ksh. 7,000/= per month to the house help
Special damages as pleaded (Ksh. 54,720/=)
Only Ksh. 44,700/= was proved; illegible medical receipts were disregarded and only the pleaded sum of Ksh. 2,500/= for the medical report was awarded despite a Ksh. 3,000/= receipt
Plaintiff's proposed multiplier of 20 years on earnings of Ksh. 112,000/= per month for loss of earning capacity (Ksh. 17,472,000/=)
The multiplier approach is inappropriate for loss of earning capacity; a global sum approach was adopted instead

Costs of the suit awarded to the plaintiff ("The plaintifi is also awarded interest on the damages as well as costs of the suit.")
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.
In summary, I hold that the plaintifi has proven his case on a balance of probabilities as against the defendants.
General damages for pain, sufiering and loss of amenities... Ksh. 3,500,000/= Loss of earning capacity…………………… Ksh. 1,000,000/= Special damages…………………………………………… Ksh. 44,700/=
Balance due to the plaintifi………… Ksh. 4,090,230/=
The plaintifi is also awarded interest on the damages as well as costs of the suit.
My analysis of the above authorities is that given the nature of the claim for loss of earning capacity, the multiplier approach would be inappropriate.
It is trite law that special damages must be specifically pleaded and strictly proved.
Issues in the judgment
#The disposition describes the plaintiff (female) as 'his case', an apparent typographical inconsistency with the rest of the judgment
Inconsistency in the plaintiff's stated age: paragraph 32 states she was 39 at the time of accident, while the submissions in paragraph 10 state she was 46
Defence doctor's name appears inconsistently as 'Wambush' and 'Wambugu' in the judgment
