Better Public Appointments: Matemu Integrity Review

A court reviewing a public appointment faces a difficult balance. If judges refuse to examine appointments at all, constitutional standards of leadership and integrity can become political promises with no legal consequence. If judges reassess every candidate as though they were members of the selection panel, the court itself begins to take over a function assigned to Parliament, the Executive or another appointing institution.

Matemu v Trusted Society of Human Rights Alliance is valuable because it explains the space between those extremes. The Court of Appeal accepted that Chapter Six of Kenya's Constitution is enforceable and that public appointments can be reviewed. It nevertheless insisted that the judicial question is ordinarily legality and rationality, not whether judges personally regard one candidate as better than another.

The appointment dispute

Matemu v Trusted Society of Human Rights Alliance & 5 others, Civil Appeal 290 of 2012 [2013] KECA 445 (KLR), concerned the appointment of Mumo Matemu as chairperson of the Ethics and Anti-Corruption Commission. A statutory selection process had advertised the office, shortlisted and interviewed candidates and ultimately resulted in Matemu's nomination and parliamentary approval.

Trusted Society challenged the appointment. It relied on allegations connected with Matemu's earlier work at the Agricultural Finance Corporation and argued that he did not meet the constitutional integrity requirements for leading the anti-corruption commission. The High Court set aside the appointment, concluding that the appointing institutions had not sufficiently investigated the material raised against him.

The Court of Appeal reversed that result. Importantly, it did not say that Chapter Six was non-justiciable. It accepted that courts may review public appointments for constitutional and statutory compliance. The error, in its view, was that the evidence and pleadings did not justify the degree of judicial substitution that had occurred.

Standing opens the door, but proof still wins the case

One important feature of Matemu is its approach to public-interest standing. Articles 22 and 258 of the Constitution deliberately moved Kenya away from narrow rules requiring every claimant to prove a private injury. A civil society organisation can therefore challenge a public appointment in the public interest where the case genuinely raises constitutional legality.

That broad standing does not lower every other legal requirement. The claimant must still identify what was done, which constitutional or statutory duty was breached and how the available evidence proves the defect. Matemu reaffirmed the Anarita Karimi Njeru requirement of reasonable precision while warning that precision is not mathematical exactitude.

This distinction remains important in current public law. A petitioner may have full standing and still lose because the pleaded case is vague or the evidence does not connect the challenged decision to a constitutional violation. Standing answers who may bring the case. It does not answer whether the case is proved.

The rationality test protects both integrity and institutional roles

The Court of Appeal framed review around a rational connection between the appointment process and the legal purpose of the office. A court may ask whether the responsible body considered the legally relevant criteria, complied with mandatory procedure and dealt rationally with material bearing on integrity or suitability. It may intervene where the process ignores the law, rests on irrelevant considerations or lacks any rational connection with the statutory and constitutional objective.

What the court should ordinarily avoid is an independent merits assessment of the candidate. Judges do not sit as an additional interview panel simply because they might have weighed experience, temperament or allegations differently. Institutional deference is therefore not immunity. It protects a lawful exercise of assigned discretion, not arbitrary or unconstitutional appointment.

Recent Kenyan appointment litigation continues to rely on this distinction. Courts considering challenges to appointments in 2025 cited Matemu when analysing whether review should test procedural legality and rationality without replacing the judgment entrusted to the selecting or approving institution.

The current legal framework is broader than it was in 2013

The statutory environment has changed since Matemu was decided. The Ethics and Anti-Corruption Commission Act has been amended several times, including changes in 2024 and 2025. Its current provisions continue to require the chairperson and members of the Commission to satisfy Chapter Six standards and specified professional qualifications.

The Leadership and Integrity Act is also current and was amended by the Conflict of Interest Act 2025. It remains the principal statute giving effect to Chapter Six through standards governing State officers. Where parliamentary approval is required, the Public Appointments (Parliamentary Approval) Act continues to regulate the approval process and the matters Parliament must examine.

A modern challenge should therefore not rely on Matemu alone. The advocate must identify the constitutional article, the current version of the statute governing the particular office and the specific appointment procedure that applied when the decision was made. A precedent supplies the test; current law supplies the present duty.

International integrity standards add context, not a substitute test

The United Nations Convention against Corruption offers a useful international reference point. Article 7 encourages public-sector recruitment and appointment systems based on efficiency, transparency and objective criteria such as merit, equity and aptitude. The African Union Convention on Preventing and Combating Corruption also emphasises integrity and anti-corruption measures in public service.

These instruments do not replace Kenya's Constitution or determine whether a particular nominee satisfies Article 73. Their value is contextual. They reinforce the policy behind transparent, objective and integrity-based public appointment systems while leaving the domestic legality of an appointment to Kenyan constitutional and statutory law.

For legal writing, that distinction matters. International standards can illuminate why a transparent and evidence-based appointment process is important, but the court must still decide the case through the Kenyan provisions governing the office.

How to challenge an appointment effectively

A strong challenge should be organised around an institutional failure that can be proved. The claimant should identify the legal criteria for the office, the stage at which the alleged defect occurred, the material that was before the decision-maker or ought lawfully to have been considered, and the reason the process lacked a rational connection to the constitutional purpose.

Evidence is especially important in integrity cases. Allegations may justify inquiry, but an allegation is not automatically proof of misconduct. Relevant material can include the advertisement, statutory qualifications, shortlist, interview record where available, public memoranda, committee reports, Hansard, official reasons, verified investigative findings and correspondence showing how a concern was handled.

The remedy should also fit the defect. Where the problem is an unlawful process, reconsideration through a lawful process may be more institutionally appropriate than an order effectively selecting or rejecting the candidate on the court's own view of the merits.

What appointing bodies should learn from Matemu

Selection panels, parliamentary committees and executive offices should build a record capable of explaining why their decision was lawful. Published criteria should be applied consistently. Credible integrity concerns should be acknowledged and assessed. Reasons should show that the institution considered the matters the law required it to consider.

A transparent record makes judicial deference more likely because the court can see the rational path from legal criteria to outcome. An opaque process creates the opposite problem. If the institution cannot show what it considered or why it reached its conclusion, the court has less reason to assume that constitutional standards were genuinely applied.

Matemu therefore improves appointments from both sides of litigation. It disciplines claimants by requiring precision and evidence, while also disciplining public bodies by demanding an appointment process connected to constitutional purpose.

Why the case matters

Matemu is not a judgment saying that courts should keep away from public appointments. It is a judgment about how courts should intervene. Chapter Six is law. Public-interest standing is broad. Yet constitutional review remains review, not a second appointment exercise.

For ordinary readers, the distinction can be expressed simply: a court may ask whether the lawful decision-maker used a lawful, rational and constitutionally relevant process. It should not normally ask whether the judge personally would have chosen the same candidate.

That balance explains why Matemu continues to be cited. It protects public institutions from judicial substitution while preserving a real judicial remedy where integrity, legality or mandatory appointment standards have been ignored.
