Trusted Society of Human Rights Alliance v Matemo & 5 others
The bottom line
#The Law Society of Kenya cannot intervene in court to support individual members or challenge pleadings.
What this practically means
#The Supreme Court of Kenya dismissed the Law Society of Kenya's attempt to join a case in support of an individual lawyer. The court explained that the LSK's role is to serve the public interest, not to champion individual causes. It also said the LSK cannot question the quality of court documents once a case is filed. Only neutral legal experts or parties with a direct stake in the outcome can join a case.
Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Who is an Intervener and what role does he/she play?
- 2.In what circumstances is an Intervener enjoined in proceedings?
- 3.What is the difference between an Intervener and Amicus curiae?
- 4.What is the mandate of the LSK under the Society's Act? Can it take sides in proceedings on the basis of this mandate?
- 5.Does LSK have a role to play in respect of the quality of pleadings as filed in Court?
Key legal issues
#What is the distinction between an intervener (interested party) and an amicus curiae?
An interested party has a personal stake in the proceedings and will be directly affected by the outcome, whereas an amicus curiae is a neutral party admitted to assist the court in reaching an informed decision without taking sides.
The court examined Black's Law Dictionary definitions and its own precedent in the Raila case. It held that an interested party has a 'recognizable stake' and will be affected by the decision, while an amicus has 'fidelity to the law' and seeks only a legal and legitimate outcome. The LSK had declared partisan support for the 1st respondent, making it unsuitable as amicus and improper as an interested party.
Can the Law Society of Kenya use its statutory mandate to intervene in proceedings in support of an individual member?
No. The LSK's mandate under section 4 of the LSK Act is to champion the wider public interest, not individual interests. Using it to support an individual member would be ultra vires its statutory mandate.
The court considered section 4 of the LSK Act, which includes objectives to assist the government and courts and to protect the public. It reasoned that allowing LSK to champion an individual's interest would subvert its public-interest mandate. The LSK had declared support for the 1st respondent, making its intervention partisan and improper.
Does the Law Society of Kenya have locus standi to challenge the quality of pleadings in a pending case?
No. Once a matter is filed and the court is seized of it, the LSK has no locus standi to intervene regarding the quality of pleadings. The court has its own procedural rules to address defective pleadings.
The court noted that a suit is a 'solemn process' owned by the parties. The LSK's mandate to ensure high standards of advocacy is achieved through training and continuous legal education, not by 'policing' pleadings in court. The court has mechanisms like the Civil Procedure Rules to filter matters.

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.
We find and hold that the LSK has manifested its partisan support for the 1st respondent, and on this account it was improper for it to be enjoined as an interested party and much less, as amicus.
LSK cannot invoke section 4 where it seeks to champion the interests of an individual. The wide mandate bestowed on LSK to protect and assist the public in Kenya, cannot be read in such a manner as to allow it to perpetuate an individual's interest.
Once the matter is filed and the Court is seized of it, the LSK has no locus standi to intervene with regard to the quality of pleadings.
The upshot is that the LSK's application to be enjoined as an interested party in this matter is hereby dismissed. In exercise of the Court's discretion, there shall be no order as to costs.
Key timeline
#Practical implications
#Clearer rules for joining cases
Lawyers should distinguish between an interested party (personal stake) and an amicus curiae (neutral). The court will reject applications that show partisanship. LSK cannot use its statutory mandate to support individual advocates in court. When advising clients on intervention, ensure they demonstrate a direct interest, not just a general concern.
LSK cannot join commercial disputes
Businesses in litigation should note that the Law Society of Kenya cannot be used as a tool to challenge pleadings or support a party. If a dispute involves LSK's public interest mandate, the LSK must remain neutral. This ruling prevents LSK from being drawn into private litigation on behalf of individual lawyers.
LSK won't champion your personal case
If you are a lawyer or any individual in a case, you cannot expect the Law Society of Kenya to intervene on your behalf. The LSK's role is to protect the public, not individual interests. You must rely on your own legal representation and cannot use LSK to challenge the quality of pleadings in your case.
