Kenya Shell Limited v Milkah Kerubo Onkoba
The bottom line
#Kenya's Court of Appeal confirmed that companies storing fuel underground are strictly liable for leaks, even without negligence, and must pay for the damage caused.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether liability for contamination of the respondent's borehole was established against the appellant
- 2.Whether the plaint disclosed a specific tort despite not naming it
- 3.Whether the defence of Act of God was available
- 4.Whether the respondent discharged the duty to mitigate her loss
- 5.Whether the award of general damages of Kshs.600,000 was excessive or erroneous
Key legal issues
#Applicability of the rule in Rylands v Fletcher
The rule applies; the appellant, as occupier keeping diesel in an underground tank, was strictly liable for its escape into the respondent's borehole.
The court adopted Salmond on Torts' formulation: one who brings and keeps on land anything likely to do damage if it escapes is bound at his peril to prevent its escape and liable for direct consequences even without negligence. Blackburn J's formulation in Rylands was hailed as a masterpiece and applied without hesitation; the Act of God defence failed on the evidence.
Liability by conduct/admission
The appellant admitted liability by supplying water for two weeks and attempting unsuccessfully to clean the borehole.
After the leakage the appellant made efforts to clean the borehole and supplied water; these post-incident actions were treated as an admission of liability. The appellant also offered no rebuttal evidence, leaving the respondent's evidence, including the Kenya Bureau of Standards report, uncontroverted.
Mitigation of loss
The respondent discharged her duty to mitigate by obtaining alternative water; she was not required to sink a new borehole while pollution continued and the appellant did nothing.
The abortive cleaning attempts confirmed continuing pollution; it would be unreasonable to expect the respondent to sink a Kshs.6,000 borehole until the appellant repaired the leak or removed the tank. The appellant took no preventive steps, and the global award cushions the respondent against unascertainable continuing loss.
Quantum of general damages
The global award of Kshs.600,000 was left undisturbed; an appellate court will not interfere with judicial discretion in quantum absent valid reasons.
Although the borehole cost only Kshs.6,000 to construct, the pollution was continuing and its full extent unascertainable at hearing; the global sum cushioned the respondent against that continuing loss. The court therefore found no basis to interfere with the superior court's discretion.
Sufficiency of pleadings identifying the tort
The plaint's averments were sufficiently clear to indicate the tort under Rylands v Fletcher; failure to name the tort is not fatal.
The particulars given in the plaint pointed to the strict liability tort, and the expert report from the Kenya Bureau of Standards established the escape of diesel from the underground tank into the neighbour's borehole, so the claim survived the absence of a named tort.
Legal principles established
#- The rule in Rylands v Fletcher, a rule of absolute or strict liability, applies to escape of diesel from an underground tank into a neighbouring borehole.
- Liability may be admitted by conduct, such as supplying water and attempting to clean the contaminated borehole after the escape.
- Failure to name the specific tort in the plaint is not fatal if the particulars plead point to the tort.
- The polluter pays principle informs awards where pollution is continuing and the full extent of loss is unascertainable.
Court orders
#- 1.The appeal is dismissed
- 2.Costs to the appellant (as stated in the judgment's final order)
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court of Kenya at Kisii
- Jurisdiction invoked
- First appeal to the Court of Appeal under the Constitution of Kenya and the Appellate Jurisdiction Act (appeal from the judgment and decree of the High Court)
Relief refused
#Setting aside or varying the award of Kshs.600,000 general damages
No valid reasons to interfere with the superior court's exercise of discretion
Act of God defence
Not borne out by the evidence; the appellant gave no evidence explaining the leakage
Costs
"the appeal is dismissed with costs to the appellant" (as drafted; likely a slip, since dismissal would ordinarily carry 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 a rule of absolute or strict liability recognized by our law – one of the chief instances in which a man acts at his peril and is responsible for accidental harm, independently of the existence of the wrongful intent or negligence.
The occupier of land who brings and keeps upon it anything likely to do damage if it escapes in bound at his peril to prevent its escape, and is liable for all the direct consequences of its escape, even if he has been guilty of no negligence
It is a cardinal principle of environmental law that the polluter must pay.
In the result, the appeal is dismissed with costs to the appellant.
Issues in the judgment
#Costs order contradicts the dismissal outcome: appeal dismissed yet costs awarded to the appellant.
