JOO v MBO; Federation of Women Lawyers (Intended Interested Party); Law Society of Kenya & 3 others (Intended Amicus Curiae)
The bottom line
#Court can admit a party as amicus curiae even if they don't qualify as an interested party.
What this practically means
#The Supreme Court of Kenya ruled on who can join a case as an interested party or friend of the court. To be an interested party, you must show a personal stake in the matter, that you will suffer harm if left out, and that your arguments are not just repeating what others will say. The court can still let you participate as a friend of the court (amicus curiae) in public-interest cases, even if you don't meet the strict interested-party test. This is a privilege, not a right, and the court limits participation to avoid overcrowding.
Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the Federation of Women Lawyers (FIDA Kenya) should be enjoined as an interested party.
- 2.Whether the Law Society of Kenya (LSK) should be enjoined as amicus curiae.
- 3.Whether KELIN, ISLA, and HRW should be enjoined as amici curiae.
Key legal issues
#Whether FIDA Kenya met the criteria for enjoinment as an interested party under Rule 24 of the Supreme Court Rules, 2020.
FIDA Kenya did not meet the criteria because they failed to demonstrate a personal stake, prejudice, or that their submissions were not a replication of the parties' submissions.
The court applied the principles from the Muruatetu case, which require an interested party to show a personal interest, prejudice from non-joinder, and that their submissions are not a replication. FIDA Kenya's application did not satisfy these elements, as they only argued ongoing matrimonial property cases and did not show how their submissions would differ from the principal parties.
Whether the court can enjoin a party in a capacity different from that which they sought.
The court can, in its discretion and in unique public-interest matters, enjoin a party that sought enjoinment as an interested party in the capacity of amicus curiae.
The court relied on its decision in the Muruatetu case, where it admitted an intended interested party as amicus curiae due to the unique and public-interest nature of the matter. The court found that FIDA Kenya's submissions were more suited to the role of amicus curiae and would bring additional material on the subject of the petition.
Whether KELIN, ISLA, and HRW met the criteria for enjoinment as amici curiae under Rule 19 of the Supreme Court Rules, 2020.
They did not meet the criteria because their expertise was not shown to be crucial to the matter, and the court was wary of crowding the primary parties.
The court considered the principles from Mumo Matemu and Muruatetu, which require proven expertise, independence, impartiality, and public interest. The court found that while the applicants claimed expertise in women's, land, and property rights, they did not demonstrate how their admission was crucial to the specific issues in the petition. The court also noted that they could liaise with admitted amici curiae.

Key timeline
#Practical implications
#Drafting joinder applications carefully
When applying to join a case as an interested party, clearly state your personal stake, the specific prejudice you will suffer if not joined, and how your submissions differ from the main parties. If you cannot meet this test, consider applying as amicus curiae instead, but be prepared to show your expertise is crucial to the case. The court may convert your application, but it's not guaranteed.
Joining public-interest litigation
If your business wants to participate in a public-interest case, you must show a direct and identifiable interest in the outcome, not just a general concern. For example, if a case affects your industry's regulations, you may qualify as an interested party. Otherwise, you might be admitted as a friend of the court, but only if your expertise is essential and you don't duplicate existing arguments.
Your rights to join a court case
If you want to join a case that affects you personally, you must prove you have a direct stake in the outcome and that you will be harmed if you are not included. Simply having a general interest or similar experiences is not enough. The court may still let you participate as a friend of the court in special public-interest cases, but this is at the court's discretion and not a guaranteed right.
Frequently asked questions
#What is the difference between an interested party and amicus curiae in Kenya?+
An interested party has a direct personal stake in the case and will be affected by the outcome. An amicus curiae (friend of the court) provides expert assistance to the court but has no personal interest. In Kenya, the Supreme Court requires interested parties to show a clear interest, prejudice, and unique submissions, while amici curiae must prove their expertise is crucial.
Can I join a Supreme Court case in Kenya as an interested party?+
Yes, but you must meet strict criteria: show a personal and proximate interest in the matter, demonstrate you will suffer prejudice if not joined, and prove your submissions are not just repeating what other parties will say. If you don't meet these, the court may still admit you as amicus curiae in public-interest cases, but this is a privilege, not a right.
What is the Muruatetu case and how does it affect joinder in Kenya?+
The Muruatetu case is a landmark Supreme Court decision that set the rules for joining cases as interested parties or amici curiae. It requires interested parties to show a personal stake, prejudice, and unique arguments. The FIDA Kenya case applied these principles, allowing the court to convert an interested party application to amicus curiae in public-interest matters.
How does the court decide who can be amicus curiae in Kenya?+
The court considers whether the applicant has proven expertise that is crucial to the specific issues in the case, independence, and impartiality. It also guards against overcrowding the primary parties. Admission is a privilege, not a right, and the court may limit participation to written submissions only, as seen in the FIDA Kenya case.
