Haroun O. Nyamboki v Catholic University of Eastern Africa (A.M.E.C.E.A) [2017] KECA 744 (KLR)
The bottom line
#Kenya's Court of Appeal dismissed a landowner's sewage nuisance claim because he could not prove the contaminated water came from the university's plant.
What this practically means
#Executive summary
#Key legal issues
#Whether the tort of nuisance was established against the respondent
No - the source of the seepage was not proved to be the respondent's sewerage plant, and the plant was a natural use of land given the hostels
Jointly-commissioned water specialists found the origin of contamination uncertain; even the appellant's engineer's report was unclear on the source and samples were collected without the respondent. Seepage occurred in the rainy season and topography pointed to higher-gradient parcels. The City Council had found the plant properly constructed. Remedial measures were not admissions of liability.
Whether EMCA applied to the dispute
No - the cause of action arose in 1999 upon construction of the plant, before EMCA came into force on 14th January 2000
The appellant's cause of action was based on the construction of the sewerage plant, which predated EMCA's commencement. Subsequent measures taken by the respondent were not attributed at trial as contributing to the nuisance, so no EMCA-governed act was pleaded.
Whether the trial Judge properly exercised discretion in awarding interest on costs
Yes - section 27(2) of the Civil Procedure Act confers a discretionary power to award interest on costs not exceeding 14% per annum, exercised judiciously
The court cited section 27(2) of the Civil Procedure Act, held the power discretionary, and found no reason to interfere with the trial Judge's award of interest on costs from the date of filing of the suit.
Legal principles established
#- To establish liability in nuisance under the Rylands v Fletcher rule, a plaintiff must prove that the defendant brought on his land something likely to do mischief, made a non-natural use of land, that the thing escaped, and caused foreseeable damage.
- A landowner's remedial measures taken on suspicion of causing a nuisance do not amount to an admission of culpability where the source of the harm is not established.
- A first appellate court may interfere with trial findings only where the trial judge failed to take into account particular circumstances or relied on demeanour findings inconsistent with the evidence.
