Erdemann Property Ltd v Board of Management, Ngara Girls High School & 3 others (Civil Application E510 of 2025) [2026] KECA 1121 (KLR)
The bottom line
#The Court of Appeal paused a Kshs. 23 million demolition and damages order against a developer, but only if it immediately stops polluting operations and secures the money by bank guarantee.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the applicant has an arguable appeal under rule 5(2)(b)
- 2.Whether, absent the orders sought, the appeal would be rendered nugatory
Key legal issues
#Arguability of the intended appeal
The intended grounds, including jurisdiction of the ELC given alternative remedies and the finding of trespass, were arguable.
The Court did not make definitive findings on the merits; it held that the jurisdictional challenge (whether the ELC could entertain a constitutional petition where the grievance sounds in contract/lease and alternative remedies exist under the Land Act and before the NET) and the factual dispute over whether the leased property existed or belonged to the School were bona fide grounds meriting ventilation on appeal.
Nugatory value absent stay
Execution of demolition, restoration and payment of Kshs. 23,000,000 would render the appeal nugatory.
Demolition of structures and restoration of the property would create an irreversible state of affairs if the appeal succeeded. Further, payment of the decretal sum to a public school dependent on State funding might not be recoverable. These factors satisfied the second rule 5(2)(b) principle on the material before the Court.
Balancing stay against public interest and children's rights
The stay was granted on conditions: cessation of the polluting batching plant operations and provision of a bank guarantee for the decretal sum.
The Court recognised that the 1st respondent is a public school with children whose rights to a clean environment and health may be affected by the applicant's activities. It therefore conditioned the stay on the applicant immediately ceasing the blasting, noisy and polluting operations, and on securing the decretal sum by bank guarantee within 45 days.
Legal principles established
#- An applicant under rule 5(2)(b) must demonstrate an arguable appeal and that the appeal would be rendered nugatory absent the orders sought.
- On arguability, the applicant need only show a single bona fide arguable ground, not one that must succeed.
Court orders
#- 1.An order staying execution of the judgment and decree of the Environment and Land Court dated 18th July 2025 in ELC Constitutional Petition No. E066 of 2024 pending the hearing and determination of the applicant's intended appeal
- 2.The stay is conditional upon the applicant immediately ceasing operation of the cement batching plant which entails blasting, noisy emissions and water pollution within the suit property
- 3.The stay is further subject to the applicant providing a bank guarantee in the sum of Kshs. 23,000,000 within forty-five (45) days from the date of the order
- 4.Costs of the application to abide the outcome of the appeal

Issues in the judgment
#The date of delivery ('DATED AND DELIVERED AT NAIROBI THIS 12TH DAY OF JUNE 2026') post-dates the impugned judgment of 18th July 2025 and submissions of 30th October 2025; the sequence is internally consistent but the year 2026 appears unusual and should be verified against the official record.
