The promulgation of Kenya's Constitution in 2010 marked a watershed moment in the country's legal history, introducing a robust Bill of Rights and establishing constitutional petitions as a primary mechanism for enforcing fundamental freedoms. Under Article 258 of the Constitution, every person has the right to institute court proceedings claiming that a right or fundamental freedom in the Bill of Rights has been denied, violated, or infringed, or is threatened with denial, violation, or infringement.
Constitutional petitions are filed directly in the High Court pursuant to Article 165(3)(b), which grants the court jurisdiction to determine whether any law is inconsistent with or in contravention of the Constitution. Unlike ordinary civil litigation, constitutional petitions follow a simplified procedure governed by the Constitution of Kenya (Protection of Rights and Fundamental Freedoms) Practice and Procedure Rules, 2013. A petition need not be in any specific form, but must set out the facts giving rise to the violation, the constitutional provisions allegedly breached, and the reliefs sought.
The standing requirements for filing constitutional petitions are notably liberal. Article 258(2) allows a person to act in their own interest, on behalf of another person who cannot act in their own name, as a member of a group or class of persons, in the public interest, or in association with another person or group. This broad locus standi has democratized access to justice and enabled public interest litigation to flourish in Kenya.
The reliefs available in constitutional petitions are equally expansive. Under Article 23(3), a court may grant appropriate relief including a declaration of rights, an injunction, a conservatory order, a declaration of invalidity of any law that is inconsistent with the Constitution, an order for compensation, or an order of judicial review. The flexibility of these remedies ensures that courts can fashion appropriate and effective relief tailored to the specific constitutional violation.
However, constitutional petitions must not be used as a substitute for ordinary civil claims. The courts have consistently held that where a dispute can be adequately resolved through established statutory mechanisms or ordinary civil proceedings, a constitutional petition is inappropriate. This principle prevents the trivialization of constitutional adjudication and ensures that the constitutional court focuses on genuine questions of constitutional interpretation and enforcement.
