Kiboko Water Resource Users Association v Kenya Pipeline Company Limited & 3 others (Environment and Land Petition 13B of 2019) [2025] KEELC 8047 (KLR)
The bottom line
#Kenya's Environment and Land Court ruled association members cannot join a petition as co-petitioners because their association already represents their interests.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the application is res judicata in view of the ruling of 20th December, 2022
- 2.Whether the Applicants should be joined in this petition
Key legal issues
#Whether the joinder application was res judicata given the ruling of 20th December, 2022
The application is not res judicata because the earlier ruling dealt only with the petitioner's legal standing, not with joinder of members
Section 7 of the Civil Procedure Act requires that the matter directly and substantially in issue must have been directly and substantially in issue in a former suit between the same parties and finally decided. The ruling of 20th December, 2022 determined only whether the petitioner association had legal capacity to sue. No issue of joinder of members was raised or decided in that ruling, so Section 7 is not attracted.
Whether the Applicants should be joined as petitioners
Joinder refused: the applicants were unidentified and, as members of the petitioner, their interests are catered for by the association
The applicants were not clearly identified - it was uncertain whether the 5,000 members or the 203 listed members were intended. The applicants conceded the petitioner has locus standi, and the same officials (including the secretary who swore the supporting affidavit) appear in both the petition and application documents. Internal wrangles and questions of representation are matters the court has no jurisdiction to address in this application; a society's members' interests are represented by the society.
Legal principles established
#- An association with locus standi can adequately represent the interests of its members, who cannot be joined in the suit in their own right
- A joinder application is not res judicata where the prior ruling determined a different issue (legal capacity) and did not address joinder of members
Court orders
#- 1.The Applicants' notice of motion dated 31st October, 2025 seeking joinder as petitioners is dismissed
- 2.No orders as to costs
The bench
#One judgment of the whole court — no separate or dissenting opinions.
Wrote the judgment

- Original jurisdiction over the petition; joinder application under the Civil Procedure Act and Societies Act framework (specific enabling provision not cited in the ruling)
Relief refused
#Joinder of the Applicants/intended petitioners as petitioners in the petition
The intended applicants were not identified, and as members of the petitioner association their interests are adequately represented by the petitioner
Costs of the application
Application dismissed with no orders as to costs because this is a public interest litigation
Costs
Dismissed with no orders as to costs, as this is a public interest litigation.
Quotable passages
#Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.
There was no issue raised on whether members of the petitioner could be joined in the petition. I therefore find that this application is not res judicata.
This being the case, the Association can adequately represent the interest of its members.
If there are any internal wrangles amongst the oficials, this court does not have jurisdiction to address the same. Equally if there is an issue of representation that is not an issue which can be raised in this application.
I therefore find that this application is devoid of merit. The same is dismissed with no orders as to costs as this is a public interest litigation.
Issues in the judgment
#The judgment does not state the case number, court, or station of the petition in which the application was made
The Applicants assert they participated until a ruling of 14th February, 2024, yet the earlier ruling cited by the Respondents and the court is dated 20th December, 2022; the relationship between the two rulings is not clarified
