Key legal issues
#Liability for the workplace accident
Respondent solely liable for failing to provide safe working machinery with a faulty limit switch
The claimant's unshaken evidence was that the mould closed on its own due to a faulty limit switch. RW1 did not witness the accident; his account of the claimant tying the switch was not pleaded in the defence and rested on an undisclosed investigation report never produced. The supervisor and co-shift workers were not called. The evidential weight therefore tilted to the claimant on a balance of probability.
General damages for pain, suffering and loss of amenities
Kshs. 1,200,000 awarded, adopting 40% disability per WIBA First Schedule and adjusting City Engineering Works award for inflation
Dr. Wokabi assessed 50% permanent disability and the respondent produced no counter medical report. The court perused the WIBA First Schedule confirming loss of four fingers equals 40% disability, used the comparable City Engineering Works award of Kshs. 600,000, and doubled it for passage of time and inflation.
Loss of earning capacity
Multiplier of 15 years applied to salary of Kshs. 7,000, yielding Kshs. 1,260,000
The court took judicial notice of retirement age of 60; the claimant was injured at 34 leaving 26 years to retirement. Guided by the cited authorities and 40% incapacity, a reduced multiplier of 15 years was held reasonable, computed as Kshs. 700 x 12 x 15.
Special damages
Kshs. 2,000 for medical report awarded as pleaded and proved; Kshs. 10,000 witness expenses allowed despite not being pleaded
The rule that special damages must be specifically pleaded and proved was applied to the Kshs. 2,000 medical report fee, proved by receipt. The Kshs. 10,000 court attendance fee was not pleaded, but the court held witness expenses need not form part of pleadings and allowed it.
Legal principles established
#- An employer's liability is established where it allocates an employee duty on machinery with a faulty safety switch, failing to provide safe working machinery
- Unpleaded defence allegations not supported by admissible evidence fail; hearsay investigation evidence without the report or investigator carries no weight
- Special damages must be specifically pleaded and proved
Court orders
#- 1.Judgment entered for the Claimant: general damages for pain, suffering and loss of amenities of Kshs. 1,200,000
- 2.General damages for loss of earning capacity of Kshs. 1,260,000
- 3.Special damages of Kshs. 12,000
- 4.Total award of Kshs. 2,472,000 less Kshs. 283,661.50 paid under WIBA, leaving Kshs. 2,188,338.50
- 5.Costs and interest at court rate from date of judgment

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.
Therefore I hold that the Claimant has proved on a balance of probability that the material accident was cause by the negligence of the Respondent by failing to provide safe working machinery.
Without evidence of an eye witness, the Claimants evidence stands unshaken. The evidence of RW1 is hearsay.
In the end I find the Respondent solely liable for the accident.
Consequently I enter judgment for him as follows:
d) Costs and interest at court rate from date hereof
Issues in the judgment
#Judgment dated in the future (2026) for a 2024 cause
