The Owino-Uhuru environmental dispute in Mombasa County shows why an award must be read with its appellate history. The Supreme Court reversed the 2023 treatment of compensation and restoration in 2024. A 2026 review motion failed. These decisions do not establish payment, completed restoration or present enforceability.

What the 2023 appeal decided
Residents alleged that factory pollution and regulatory failures violated environmental rights. The Court of Appeal recorded that the infringement findings were not disputed and upheld ELC jurisdiction over this constitutional claim. (Paragraphs 1-9, 39-46.)
Public liability rested on each authority's failures and their causal connection with harm. NEMA failed in assessment and enforcement; EPZA licensed operations without the required environmental licence; the Environment ministry licensed prematurely; the Health ministry failed to secure nuisance removal. These were findings, not blanket liability for regulators. (Paragraphs 26-27, 66-86; Supreme Court, paragraphs 110-125.)
The allocation became Environment ministry 5%, Health ministry 5%, NEMA 30%, EPZA 10%, factory operator 40% and premises company 10%. Mombasa County Government received no allocation: despite questioning its exoneration, the court declined to revisit it without a cross-appeal. (Paragraphs 86-89, 111(2).)
The appeals partly succeeded, setting aside these 16 July 2020 trial orders:
- KSh1.3 billion compensation, originally payable within 90 days with execution in default.
- Cleanup within 120 days, with KSh700 million due in default to community organisation CJGEA to coordinate restoration, and related default provisions.
It remitted compensation assessment, including limited additional evidence, to another ELC judge. NEMA was directed to identify contamination, remove it and restore the environment within twelve months, consulting relevant agencies and private actors, with three-monthly ELC reports until satisfactory completion. Other orders survived except as modified, including regulatory mandamus against the Attorney General, Environment ministry and NEMA. Trial costs remained for the petitioners; no appeal costs were ordered. (Paragraphs 28(d)-(e), 105, 111(1)-(6).)
Those are historical terms, not fresh deadlines or the last remedial decision.
The 2024 Supreme Court reversal controls the remedial account
On 6 December 2024, the Supreme Court decided [2024] KESC 75 (KLR), Petitions E019 and E021 of 2023. Read the Supreme Court judgment.
It retained the liability allocation but restored KSh1.3 billion compensation for the represented community, rejecting the appellate approach to constitutional damages and identification of beneficiaries. It also restored the conditional KSh700 million restoration mechanism, finding restoration had been pleaded. (Paragraphs 128, 136-155, 163, 168-174.)
Crucially, respondents were to file reports of restorative measures, if any, at the Mombasa ELC within three months of that decision. The default clause would then take effect if EPZA and the respondents had undertaken no restorative measures; the ELC would assess reports and further directions. The remittal concerned restoration compliance, not fresh compensation assessment. (Paragraphs 174-175, 183-184(iv).)
The court also directed NEMA, the Attorney General and Environment ministry to implement Basel Convention recommendations and guidelines. EPZA's appeal and NEMA's cross-appeal were dismissed; the residents' appeal succeeded to the stated extent. Parties bore their own costs across all three courts, and KSh6,000 security for costs was ordered refunded to the appellants. None of this proves disbursement. (Paragraphs 181-184.)
The 2026 review did not establish restoration or payment
On 5 March 2026, the Mombasa ELC dismissed NEMA's motion dated 22 September 2025, without costs, in [2026] KEELC 1300 (KLR), Petition 1 of 2016. NEMA's claimed natural remediation was contested; the court found it lacked jurisdiction to reopen the Supreme Court award and that credible remediation had not been demonstrated. Its remit remained restoration compliance. Read the review ruling, paragraphs 5-10, 17-20.
The separate 4 April 2025 application seeking restoration payment is recorded, not disposed of by that dismissal. (Paragraphs 3-5, 20.) The earlier search record's July 2026 enforcement lead has no located/read primary decision and remains unverified. No present contamination or enforcement outcome is asserted.
