Kamau & 142 others v Kenya Railways Corporation & 2 others (Environment and Land Petition E001 of 2025) (Environment and Land) [2026] KEELC 2578 (KLR)
The bottom line
#Kenya's Environment and Land Court ruled the Mai Mahiu flood was caused by neglected railway infrastructure, not nature, and ordered compensation and audits.
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 Petitioners have proved their case to the required standard.
- 2.Was the flash flood an unpreventable natural disaster (Act of God), or was it a foreseeable catastrophe caused by structural neglect?
- 3.Whether the ongoing reconstruction of the railway infrastructure complied with Articles 42 and 70 regarding a clean and healthy environment and the legal requirement for meaningful public participation.
- 4.Whether the prayer to halt construction has been overtaken by events.
- 5.Whether the Petitioners are entitled to declaratory orders, permanent injunctions, and compensatory damages.
Key legal issues
#Precision of pleading in constitutional petitions
The Petition was an omnibus pleading imprecise on Articles 3, 6, 10, 19, 21, 22, 23, 24, 27, 29, 46, 47, 48, 53, 56 and 57, but arguably precise on the violations of Articles 26, 40, 42, 43 and 70.
Applying Anarita Karimi Njeru, the Court found the Petitioners used a single narrative to cover more than twenty articles without showing the specific manner of infringement for most of them. However, on the right to life they identified the Dark Tower tunnel, KM 604, the failure to monitor and clear a known blockage, and linked the deaths to a structural failure rather than rain; on property they established a direct nexus between the man-made railway structure and the destruction; and on the environment they pleaded the procedural breach of missing EIA and public participation.
Whether the flash flood was an Act of God or a foreseeable catastrophe caused by structural neglect
The disaster was not an Act of God; it resulted from a state-created risk: a blocked railway tunnel whose structural failure, compounded by failure to patrol and clear drainage despite the 2020 incident and El Niño warnings, caused the loss of lives and property.
The Court accepted that the deaths were not caused by falling rain but by the tunnel's collapse, a structural failure. The 1st Respondent's failure to patrol and clear the blocked tunnel, despite prior notice from the 2020 floods and meteorological warnings, created a 'man-made dam' and breached its duty of maintenance. The artificial embankment altered natural drainage, so the destruction of property was a structural failure of State-managed property, not an unforeseeable natural event.
Whether the reconstruction complied with Articles 42 and 70 and the requirement of public participation
The Court found regulatory failure: the tunnel remained blocked for years without a NEMA-mandated environmental audit, and the reconstruction violated the precautionary principle; under Article 70(3) no proof of loss was required to establish the violation.
Relying on the Owino-Uhuru decision, the Court held that the presumption of regularity is no shield, that an agency assumes legal responsibility for shortcomings in another agency's licensing process, and that redress under Article 70(3) does not require proof of actual loss. NEMA's failure to ensure an environmental audit while the tunnel remained blocked, and the rushed reconstruction without a prior site-specific EIA, breached the State's custodial obligations under Articles 42 and 70.
Whether the injunction is moot and what remedies flow
A prohibitory injunction was overtaken by events, but the Court substituted structural remedies: compensation of Ksh 50,000 per victim, an independent safety and hydrological audit within 60 days, and quarterly reports for three years.
Because construction was substantially complete, a prohibitory injunction was no longer applicable. The Court instead invoked its wide Article 70(2) powers to issue a mandatory-type relief requiring periodic independent audits, with liberty to seek decommissioning or modification if the bridge poses an ongoing threat, and awarded modest general compensation for the violation of the right to life and loss of dignity, noting constitutional damages are restorative, not punitive.
Legal principles established
#- A constitutional petitioner must plead with reasonable degree of precision the provisions said to be infringed and the manner of infringement (Anarita Karimi Njeru standard).
- Under Article 70(3) an environmental-rights applicant need not prove loss or injury; a violation or threat of violation alone warrants redress.
- The presumption of regularity does not oust a State organ's responsibility to probe the administrative duties of another institution.
- A flood disaster occasioned by a blocked, poorly maintained man-made structure is not an Act of God but a foreseeable catastrophe caused by structural neglect attracting constitutional liability.
Court orders
#- 1.A declaration that the Respondents violated the Petitioners' constitutional rights under Articles 26, 28, 40, 42 and 43 of the Constitution.
- 2.A declaration that the Respondents failed in their constitutional and statutory obligations to protect life, property and the environment under Articles 26, 42 and 70 of the Constitution.
- 3.Compensation of Ksh 50,000/= awarded to each victim for the violation of their environmental rights.
- 4.The Respondents to undertake and publish a comprehensive, independent Safety and Hydrological Audit of the new bridge within 60 days.
- 5.The Respondents to file quarterly reports to the Court for the next three years, detailing the maintenance and clearing of the drainage tunnels at KM 604.
- 6.No costs, the Petition having been brought in public interest.
The bench
#One judgment of the whole court — no separate or dissenting opinions.
Wrote the judgment
- Jurisdiction invoked
- Articles 22, 23(1) & (3), 165(3)(a) & (b) and 258(1) and (2) of the Constitution of Kenya 2010
Relief refused
#Permanent injunction halting further construction of the soil embankment tunnel bridges in the Mai Mahiu area
The construction was substantially complete, making a prohibitory injunction moot; only a mandatory injunction coupled with periodic audits remained available.
Compensation for the full claimed losses (loss of life, livelihoods, business income, real property and personal effects)
The Court found insufficient information on eviction from land and limited the award to Ksh 50,000 per victim for violation of environmental rights rather than full compensatory damages.
Orders compelling public participation and assessment of alternative modern bridge technologies (steel arch, cable-stayed, cantilever, segmental construction)
Not granted as a distinct order; the Court instead mandated a safety and hydrological audit and quarterly reporting as structural remedies.
Costs
The Petition having been brought in public interest, there shall be no costs.
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.
A declaration that the Respondents violated the Petitioners' constitutional rights under Articles 26, 28, 40, 42 and 43 of the Constitution.
The Respondents shall undertake and publish a comprehensive, independent Safety and Hydrological Audit of the new bridge within 60 days.
The Respondents to file quarterly reports to the Court for the next three years, detailing the maintenance and clearing of the drainage tunnels at KM 604.
The Petition having been brought in public interest, there shall be no costs.
I find that the "Act of God" defence is invalid and the Petitioners are entitled to declarations
The mere violation or threat of violation to the environment is enough to warrant a court's intervention
Issues in the judgment
#Internal chronological contradiction in the 5th Respondent's affidavit regarding the railway construction dates.
Cause title lists only three Respondents (1st to 3rd) yet the body of the judgment and the prayers repeatedly refer to a 4th and 5th Respondent, and the prayers reference a 5th Respondent not named in the cause title.
The judgment refers to a decision in Mitu-Bell as 'Kenya Airports Authority v Mitu-Bell Welfare Society & 2 others' where 'the Supreme Court had affirmed' State obligations, alongside the correctly named Petition 3 of 2018, potentially conflating the Court of Appeal and Supreme Court decisions in the same matter.
