Constitutional Law Advocates in Nairobi, Kenya
Constitutional law is the core legal system that establishes how a country is governed, defines the powers of each branch of government, and protects the fundamental rights of its citizens. As the supreme law of the land, any statute, policy, or government action that conflicts with it is invalid. At Ondieki & Matoke Company Advocates, we advise and represent individuals, organisations, and public interest litigants on constitutional matters from challenging an unlawful government decision to defending a fundamental right under the Bill of Rights.
The Legal Framework
Constitutional law in Kenya is governed by the Constitution of Kenya, 2010, which replaced the 1969 independence constitution. It establishes Kenya as a sovereign republic with a devolved system of government across 47 counties, a clear separation of powers between the three arms of government, and an expansive Bill of Rights that is among the most comprehensive in the region.
Core Principles
- Supremacy — The Constitution is the supreme law of Kenya. Any other law, custom, or government action that conflicts with it is void to the extent of the inconsistency.
- People’s Power — All sovereign power belongs to the people of Kenya, exercised either directly or through democratically elected representatives.
- National Values — Under Article 10, all state organs and public officers must govern in accordance with values including human dignity, equity, social justice, equality, and transparency.
- Devolution — Governmental power is shared between the national government and 47 distinct but interdependent county governments.
- Separation of Powers — State authority is divided among the Legislature, the Executive, and the Judiciary, so that no single branch holds total control.
- Judicial Review — Kenyan courts have the power and duty to determine whether government actions and legislation comply with the Constitution, and to strike down those that don’t.

Key Pillars of Constitutional Law
- The Bill of Rights (Chapter 4) — Protects fundamental rights including life, equality, freedom of expression, and economic and social rights. Certain rights cannot be limited under any circumstances.
- Separation of Powers — Cleanly divides state authority between Parliament, the Executive, and the Courts.
- Leadership and Integrity (Chapter 6) — Sets high ethical and moral standards for all state and public officers.
- Independent Commissions (Chapter 15) — Protects key democratic institutions — including the Judiciary, the Independent Electoral and Boundaries Commission (IEBC), and the Kenya National Commission on Human Rights (KNCHR) — from political interference.

Frequently Asked Questions
A constitutional petition is a court application asking the High Court to determine whether a law, policy, or government action violates the Constitution, and to grant an appropriate remedy. It is filed before the High Court’s Constitutional and Human Rights Division, setting out the facts, the constitutional provisions engaged, and the relief sought.
Judicial review is the process by which courts examine the legality, procedural fairness, and reasonableness of a decision made by a public body or government official. It focuses on how a decision was made, rather than substituting the court’s own view for the decision-maker’s.
Depending on the nature of the decision, you may bring a judicial review application or a constitutional petition, particularly where a fundamental right has been affected. An advocate can assess which route fits your facts and the remedy you’re seeking.
Kenya’s Constitution takes a broad approach to standing a person can bring a petition where their own rights have been affected, and in many cases, public interest litigants can also bring claims on behalf of others or in the general public interest, particularly for Bill of Rights matters.
Timelines vary significantly depending on the complexity of the matter, whether interim orders are sought, and whether the case proceeds to appeal. Straightforward petitions can move relatively quickly, while matters involving significant public interest or novel constitutional questions often take longer given their complexity and the scrutiny they attract.
