Muthuuri & 4 others v Attorney General & 2 others
The bottom line
#Police constables cannot claim higher pay based on old policies that conflict with current law.
What this practically means
#Police constables who earned degrees while serving argued they should get higher pay based on old government circulars from 1969 and 1995. The Supreme Court said no. Those old policies were replaced by the 2010 Constitution and new laws. Now, any pay changes for police must involve the Salaries and Remuneration Commission. Also, the constables couldn't use other officers' pay slips as evidence without permission. So their appeal was dismissed.

Key legal issues
#Whether the appellants had a legitimate expectation to be placed in Job Group J upon acquiring degree certificates.
The appellants did not have a legitimate expectation because the 1969 circular and 1995 letter were overtaken by the 2010 Constitution and subsequent legislation, and the 2018 press release did not create an automatic entitlement.
The court found that at the time the appellants obtained their degrees (2015-2017), the applicable law was the Constitution, the National Police Service Act, and the 2015/2016 regulations. The old policy documents could not form the basis of a legitimate expectation. The press release merely restated the procedure for promotion, which required more than just presenting a degree certificate. Additionally, the pay slips relied on to show differential treatment were inadmissible as they belonged to third parties without proper authentication.
Whether the opinion of the Salaries and Remuneration Commission (SRC) was obligatory before the respondents could upgrade the appellants' salaries.
The advice of the SRC is mandatory and must be obtained before the National Police Service Commission can determine or review any remuneration or benefits for police officers.
The court interpreted Article 230(4) of the Constitution and section 10(1)(b) of the National Police Service Commission Act, which require the NPSC to act 'with the advice of the Salaries and Remuneration Commission.' This advice is binding under Article 259(11). The SRC's role is not limited to setting new salaries but extends to reviewing existing ones. Ordering the respondents to pay Job Group J salaries without SRC involvement would usurp the SRC's constitutional mandate.
Whether the pay slips produced by the appellants were admissible as evidence.
The pay slips were inadmissible because they belonged to third parties who were not parties to the proceedings, did not consent to their use, and the documents were not properly authenticated.
The court applied the principle from Njonjo Mue v IEBC that documents belonging to third parties must be obtained with the owner's consent and the source explained. The pay slips contained sensitive personal information, and using them without proper authority could violate privacy and data protection laws. Without this evidence, the appellants could not prove differential treatment or discrimination.
Legal principles established
#- A claim of legitimate expectation cannot be founded on a policy document overtaken by subsequent constitutional and statutory provisions.
- The National Police Service Commission can only determine remuneration with the mandatory advice of the Salaries and Remuneration Commission.
- Third-party documents like pay slips are inadmissible unless the owner consents and the source is explained.
- The advice of the Salaries and Remuneration Commission is binding under Article 259(11) of the Constitution.
- A press release restating promotion procedure does not create an automatic entitlement to higher pay.
Court orders

Key timeline
#Practical implications
#Key lessons for employment lawyers
This case clarifies that legitimate expectation cannot override clear statutory provisions. Lawyers should advise clients that old policy documents are unenforceable if superseded by later laws. Also, when using third-party documents like pay slips, ensure proper authentication and consent to avoid inadmissibility. The mandatory role of SRC in police remuneration is reinforced.
Implications for employers on policy promises
Employers cannot rely on outdated policies to create binding expectations if new laws have changed. Any promises of benefits must align with current statutory requirements. If a regulatory body has mandate over remuneration, its advice must be sought before implementing changes. This case highlights the importance of reviewing policies regularly.
What this means for police officers
Police officers who earn degrees cannot automatically expect a pay upgrade based on old circulars. Promotions and salary changes now require following proper procedures and involvement of the Salaries Commission. If you want to use colleagues' pay slips as evidence, you need their consent and proper authentication. Always check current laws.
Frequently asked questions
#Can Kenyan police officers get higher pay for having a university degree?+
Not automatically. The Supreme Court ruled that old policies allowing higher pay for graduate constables were replaced by the 2010 Constitution. Now, any pay changes require advice from the Salaries and Remuneration Commission and must follow proper promotion procedures.
What is legitimate expectation in Kenyan employment law?+
Legitimate expectation means an employee can expect a benefit based on a promise or consistent practice. However, this case shows that such expectation cannot override written law. If a policy is overtaken by new laws, it cannot be enforced in court.
Are third-party pay slips admissible as evidence in Kenyan courts?+
Pay slips belonging to other people are not automatically admissible. The owner must consent to their use, and the source must be explained. Using them without proper authentication can violate privacy and data protection laws.
What is the role of the Salaries and Remuneration Commission in Kenya?+
The SRC advises on salaries for public officers. For police, the National Police Service Commission must get SRC's advice before determining or reviewing pay. This advice is mandatory and binding under the Constitution.
