Sideng & 4 others (Suing on behalf of themselves and for and on behalf of Kogony Land Council of Elders Welfare) v Kenya Airports Authority & 3 others (Environment and Land Judicial Review Case 7 of 2017) [2026] KEELC 3925 (KLR)
The bottom line
#The Kisumu court refused to add 66 claimants to the Kisumu Airport land case, saying the National Land Commission had already decided it and only administrative vetting remains.
What this practically means
#Executive summary
#Key legal issues
#Whether joinder under Order 1 Rule 10(2) is competent where the substantive dispute has been determined on the merits by the National Land Commission and only adoption/execution of the award remains.
Not competent - the application was dismissed because there is no live dispute to which the proposed parties could be joined.
Order 1 Rule 10(2) exists to add parties necessary for effective and complete adjudication of a pending suit. Here, by consent, the dispute was referred to the National Land Commission under Section 15 of the National Land Commission Act, which issued a final determination published in Gazette Notice No. 7681 on 14th November 2025. Only formal adoption and administrative execution of the award remains, so there is nothing left for judicial adjudication and joinder would serve no meaningful purpose.
Whether joinder may be used to challenge the standing of the Petitioners and to define the class of beneficiaries of the compensation award.
No - such questions would require a post-judgment trial beyond the scope of a joinder application and would introduce new controversies not in the pleadings.
The suit was brought by the welfare society on behalf of the entire Kogony Clan, and the NLC award was made in favour of the Kogony Clan as so represented. The Applicants sought to relitigate who the genuine claimants are and to restrict beneficiaries to 66 persons. That would require verifying standing, ancestral links and individual property rights - a complex post-judgment trial which a joinder application cannot accommodate.
Whether the Applicants would suffer irreparable prejudice if joinder is denied.
No - their apprehension of mismanagement of the award was premature and speculative given the established administrative vetting process.
The Applicants' own supporting affidavit and the National Archives list contemplated that the full beneficiary list would be furnished after thorough investigation by the Local Administration and stakeholders. Genuine descendants of the evictees would satisfy the vetting criteria and have their interests addressed, while any improper claims by the current officials would equally be resolved in vetting. There was therefore no risk of miscarriage of justice or irreparable prejudice.
