The bottom line
#Kenya's Environment and Land Court dismissed a petition challenging the Aberdare road project, clearing the way for construction to proceed.
What this practically means
#Executive summary
#Key legal issues
#Conflict of interest in the ESIA study
No conflict of interest established; the applicable 2003 Regulations did not require a conflict declaration and Section 58 EMCA permits the proponent to undertake the EIA study
The court examined Section 58 EMCA and Regulation 13 of the 2003 Regulations, and relied on R (on the application of) vs Derbyshire County Council to explain that the proponent's assessment may be flawed but the safeguard is NEMA's independent evaluation and public consultation. PW1 conceded the Code of Ethics does not bar the designer from doing the ESIA. The 2025 Regulations requiring a conflict-of-interest declaration were not retrospective.
Violation of Article 10(2) (transparency, accountability, public participation)
No violation; the 2024 licence was based on a new ESIA Study Report on new terms of reference, and public participation was adequate
The court found the 4th Respondent issued the licence on a new ESIA Study Report of 2023 that addressed the concerns in its 2009 rejection letter. Public participation included a newspaper notice on 18/4/2023, stakeholder meetings, workshops and written submissions; the 1st Petitioner itself submitted a memorandum. Following the Supreme Court's principles in British American Tobacco, participation must be real and meaningful, which the court found was satisfied.
Violation of Articles 11, 42 and 69 of the Constitution
Not proved; mitigation measures in the ESIA Study Report and EIA Licence conditions are exhaustive and safeguard the environment if implemented
The court independently evaluated the ESIA Study Report, the EIA Licence conditions (including the offset and compensation plan) and its site visit, which confirmed the project is an upgrade of an existing motorable murram road. The Petitioners failed to tender evidence showing the mitigation measures were insufficient, and reliance on Gwer placed the burden of proof on them. Sustainable development principles guided the finding that the State did not abdicate its Article 69 obligations.
Requirement of a Strategic Environmental Assessment (SEA)
A SEA was not a legal precondition to the EIA licence under the law in force in 2024
Section 57A EMCA and Regulation 42 of the 2003 Regulations apply SEA to policies, plans and programmes, not to individual projects. The Environmental Management and Co-ordination (Strategic and Integrated Environmental Impact Assessments and Environmental Audits) Regulations 2025 were not in force when the licence was issued and cannot apply retrospectively. Additionally, the Cabinet Secretaries responsible for Vision 2030 policies were not sued and cannot be condemned unheard.
Legal principles established
#- Section 58 of EMCA allows any person including the project proponent to undertake the EIA study, and there is no legal bar to the designer of a road conducting its ESIA; the safeguard lies in NEMA's independent assessment
- Legislation cannot apply retrospectively unless it expressly states so; the EMCA (Impact Assessment and Audit) Regulations 2025 do not apply to an ESIA done in 2022-23
- Under the law prevailing in 2024, a Strategic Environmental Assessment was not a mandatory precondition to the issuance of an EIA licence for a road project; SEA applies to policies, plans and programmes
- Article 42 of the Constitution is not a veto on development; where an EIA licence identifies impacts and provides adequate mitigation measures, the project should be allowed to proceed
- A petitioner alleging violation of a constitutional right bears the burden of tendering evidence proving the alleged violation
Court orders
#- 1.The Petition dated 22nd March, 2024 is dismissed entirely
- 2.No costs awarded, the litigation being public interest litigation
- Jurisdiction invoked
- Original constitutional petition jurisdiction of the Environment and Land Court under Articles 42 and 70 of the Constitution; jurisdiction previously confirmed in a Ruling delivered 13th March 2025
