Kamau & 9 others v Aelous Kenya Ltd & 9 others (Constitutional Petition 13 of 2015) [2016] KEELC 565 (KLR)
The bottom line
#Kenya's Environment and Land Court ruled that a wind farm that changed its size and location needed a fresh environmental assessment, not just a licence variation.
What this practically means
#Executive summary
#Key legal issues
#Whether the upscaling of the project from 30MW to 61MW and its relocation from one site to 38 plots across 16 km sq could be accommodated by variation of the EIA licence under Regulation 25 of the EIA Regulations
No; the change was a substantial change or modification of the project requiring a fresh EIA, and the variation without one was contrary to law
The original licence contemplated a 2 km sq site on one land parcel; the project now covers 16 km sq across 38 parcels, an increase of about 800% in area and more than 100% in output. Regulation 25(3) permits variation without a fresh EIA only if the varied project would comply with the original licence. The Regulations give no criteria, leaving discretion to NEMA, but that discretion must be exercised reasonably. Where Regulation 28 grounds for cancellation, such as substantial change or modification, exist, NEMA must either revoke the licence or require a fresh EIA before varying it.
Whether the petitioners' right to a clean and healthy environment under Article 42 was violated
Yes, potentially - the improper variation of EIA licences threatened the right; the petition succeeded on this ground
Because the procedure for environmental protection (a fresh EIA for the new site) was not followed, the court drew the assumption that the right to a clean and healthy environment was under threat. The petitioners demonstrated impropriety in the manner the licences were varied and in implementing the project on a site never subjected to full EIA.
Whether the petitioners' rights to property (Article 40), dignity and fair administrative action were violated, and whether the leases should be quashed
No; there was nothing wrong in landowners leasing their parcels for a wind farm, and no violation of the petitioners' property or other rights was established
The interested parties voluntarily leased their land and were compensated; the petitioners retained their properties and no evidence of devaluation or displacement was presented. No law requires outright purchase of the whole wind farm area. Claims of coercion and administrative harassment were not proved, and a lessee unhappy with his lease must pursue private law remedies.
Whether the court has jurisdiction given the existence of the National Environmental Tribunal
Yes; the suit is a constitutional petition alleging rights violations, which the NET cannot hear, and the ELC's jurisdiction under Article 162(2)(b) covers all environment and land matters
The character of the suit is constitutional, not an appeal against a NEMA decision. Even if it were purely about a NEMA decision, the ELC's jurisdiction under Article 162(2)(b) and Section 13 of the ELC Act extends to any matter related to environment and land.
Legal principles established
#- Where the character, location or scope of a licensed project substantially changes, NEMA must require a fresh EIA before issuing a variation of the licence; it cannot shield behind Regulation 25 to allow a mere variation
- Where a procedure for the protection of the environment provided by law is not followed, an assumption arises that the project violates or threatens the right to a clean and healthy environment, rebuttable only by following proper procedure
- Under Section 3(4) of EMCA and Article 70(3) of the Constitution, an applicant enforcing environmental rights need not demonstrate personal loss or injury
- Even beneficial 'green' projects must comply strictly with environmental procedures; economic importance is no ground for shortcuts
Court orders
#- 1.Declared that the variation of the EIA licences issued upgrading the project to 60MW and later to a 61MW project on new sites situated in 38 plots without requiring a fresh EIA was contrary to EMCA, 1999 and the EIA Regulations, 2003
- 2.Declared that the failure to abide by the EIA Regulations, 2003 potentially threatened the petitioners' right to a clean and healthy environment under Article 42 of the Constitution
- 3.Ordered that if the proponents wish to proceed, a fresh and proper EIA under EMCA and the EIA Regulations, 2003 must be conducted and considered on merits for the new site of 38 land parcels
- 4.Awarded the petitioners the costs of the petition capped at Kshs. 2 Million all inclusive, payable by the 1st, 2nd, 3rd and 5th respondents jointly and/or severally
- Jurisdiction invoked
- Article 162(2)(b) of the Constitution and Section 13 of the Environment and Land Court Act, 2011; Articles 22, 70 and 258 of the Constitution
