Sonko’s challenge and the advisory route: institutional questions over impeachment, appeals, and electoral eligibility in Nairobi

Analysis

Introduction

In July 2026 the Supreme Court of Kenya asked the Attorney General for an advisory opinion on whether a state officer who has been impeached can stand for elective office while an appeal against that impeachment is pending. Former Nairobi Governor Mike Sonko, who was at the centre of an earlier high-profile impeachment and appeal, publicly questioned the court’s move and suggested he might pursue fresh legal action. The issue drew notice because it sits where judicial process, electoral rules and parliamentary discipline meet, raising broader questions about how courts, executive legal advisers and electoral management bodies coordinate in contested eligibility cases.

Background and timeline

Sequence of events (factual narrative):

1. Mike Sonko was removed from the office of Governor of Nairobi following impeachment proceedings, and he launched an appeal in the courts.
2. The question of whether an impeached state officer may contest elections while an appeal is pending has come up repeatedly in public debate and litigation linked to Sonko’s case and similar precedents.
3. The Supreme Court formally asked the Attorney General for an advisory opinion on the legal consequences of impeachment for electoral eligibility while appeals remain outstanding.
4. Sonko publicly challenged the need for that advisory opinion, saying the Supreme Court had already addressed the issue in his prior litigation and signalling possible new legal action.
5. The request for an advisory opinion produced reactions across political, legal and media circles because it could affect candidacy rules, electoral administration and the finality of parliamentary disciplinary processes.

Stakeholder positions

• Supreme Court (institutional action): sought an advisory view from the Attorney General to clarify how impeachment intersects with electoral eligibility during ongoing appeals.
• Attorney General (requested advisor): asked to provide a formal legal opinion to guide courts, electoral bodies and state organs on the relevant statutory and constitutional framework.
• Mike Sonko (former Nairobi Governor, litigant): questioned the request for an advisory opinion, stated that the Supreme Court had previously resolved the issue in his appeal and suggested further litigation.
• Electoral and parliamentary bodies (indirectly implicated): need clarity to administer voter rolls, nominations and oath-taking without becoming entangled in unresolved legal disputes.
• Civil society and media (public observers): raised questions about transparency, the rule of law, and the timing and purpose of advisory opinions in politically sensitive disputes.

What Is Established

• Former Nairobi Governor Mike Sonko was removed from office through impeachment and pursued appeals in the judicial system.
• The Supreme Court formally sought an advisory opinion from the Attorney General on whether impeached officers can contest elections while appeals are pending.
• Sonko publicly contested the necessity of that advisory opinion and indicated potential new legal action following the court’s request.
• Electoral administration and parliamentary processes are implicated because the answers will affect nomination and certification procedures for candidates.

What Remains Contested

• Whether the Supreme Court’s request for an advisory opinion was procedurally appropriate given prior court findings remains disputed among litigants and commentators.
• The exact legal effect of an advisory opinion on ongoing appeals and whether such advice binds electoral bodies is not finally settled.
• How quickly electoral management institutions should act during nomination windows when eligibility questions are the subject of active litigation is unsettled and operationally challenging.
• The degree to which political motivations influence requests for advisory opinions or judicial timing is debated, with uncertainty attributed to political context rather than proven misconduct.

Institutional and Governance Dynamics

The core question is how constitutional courts, the Attorney General’s advisory role and electoral administrators should interact when eligibility and disciplinary outcomes overlap. Each institution has different incentives: courts decide disputes on law and fact, the Attorney General gives legal interpretation for government actors, and electoral bodies need operational clarity to run timely elections. Those differing mandates can create gaps or overlaps. Advisory opinions may offer guidance but can also raise questions about finality. Courts may seek clarification to avoid later complications. Electoral bodies face pressure to act without being drawn into unresolved litigation. The institutional design therefore needs clearer protocols for sequencing legal clarity, administrative action and protection of broader electoral integrity.

Analysis: implications for rule of law and electoral administration

The request for an advisory opinion in a high-profile impeachment appeal highlights a recurring governance tension across African constitutional systems. Authorities must balance the finality of parliamentary discipline with individuals’ rights to judicial review, while keeping electoral processes predictable. If advisory interventions become routine in politically charged eligibility disputes, they could add layers of legal ambiguity: advisory opinions may not displace court rulings but they can influence administrative decisions and public expectations. For electoral administrators in Nairobi and beyond, the practical need is for clear timelines that reconcile nomination deadlines with possible judicial stays or interlocutory relief, so candidates are not disenfranchised and electoral schedules are not delayed.

Forward-looking scenarios

• Clarifying legislation or procedural rules: Parliament or the electoral commission could set clearer statutory guidance on how to treat candidacy when impeachment appeals are pending, for example provisional certification, conditional ballots or nomination holds.
• Judicial-Executive coordination protocols: A structured mechanism for when courts may seek advisory input from the Attorney General, and how electoral agencies should treat that input, could reduce ad hoc decision-making.
• Priority docketing for eligibility cases: Courts could prioritise appeals that affect imminent electoral deadlines, producing rulings that remove administrative uncertainty.
• Public information and transparency: Timely, clear public explanations of the legal basis and administrative steps would cut down speculation and curb politicised narratives.

Concluding observation

This episode highlights a governance trade-off common across the region: holding disciplinary and accountability mechanisms to account without leaving unresolved legal questions that disrupt electoral processes. The outcome will matter beyond the parties because it will shape institutional practice on when advisory opinions are sought and how they influence, without supplanting, judicial determinations and electoral administration.

This dispute sits within a broader African governance pattern where courts, executive legal advisers and electoral managers increasingly confront overlapping responsibilities in high-stakes political eligibility disputes. How states reconcile judicial review, parliamentary discipline and orderly electoral administration will shape public trust in the rule of law and electoral integrity across the region.
