Thange River Basin Residents' Association (Suing on Behalf of the Residents of River Thange Basin, Kibwezi Makueni County) & 44 others v Kenya Pipeline Company Ltd & 5 others (Environment and Land Petition 15 of 2019) [2026] KEELC 4927 (KLR)
The bottom line
#Kenya's Environment and Land Court ruled that people left out of an earlier oil spill compensation case can still sue Kenya Pipeline over the same spill.
What this practically means
#Executive summary
#Key legal issues
#Whether the suit is res judicata by virtue of the judgment in Makueni ELC Petition No. 9 of 2019
The plea of res judicata fails because the Petitioners in the present suit were not parties to the former suit, did not litigate under the same title, and their compensation claims were not available for adjudication in the former suit.
Section 7 of the Civil Procedure Act requires the same parties, or parties claiming under them litigating under the same title, and a matter directly and substantially in issue heard and finally decided by a competent court. Although the cause of action (the 2015 oil spill affecting Thange River Basin) is the same, the Applicant did not demonstrate identity of parties. Dismissing the suit would hinder access to justice for petitioners whose grievances have never been adjudicated.
Legal principles established
#- For res judicata to be upheld, the elements (final judgment, on merits, by a competent court, identical parties/subject matter/cause of action) must all be satisfied conjunctively
- Parties not before the former suit with distinct claims are not barred by res judicata
Court orders
#- 1.The 1st Respondent's Notice of Motion dated 25th July, 2025 seeking striking out of the further amended petition and the suit is dismissed
- 2.Costs of the application awarded to the Petitioners
- Jurisdiction invoked
- Articles 48, 50 and 159 of the Constitution; Order 2 Rule 15 of the Civil Procedure Rules, 2013
