From colonial judiciary to Africa's most respected apex court
Justice is the foundation upon which the social contract between the State and its citizens rests. The Supreme Court stands as guardian of that contract.
Key milestones that have shaped Kenya's apex court from colonial origins to constitutional guardian.
The East Africa Court of Appeal was established under the East Africa Order in Council of 1897, providing appellate jurisdiction across the British East Africa Protectorate. This court laid the early foundations of a structured judiciary in the region.
Kenya attained independence on 12 December 1963. The independence constitution established a new judicial system. The East African Court of Appeal continued to serve as the highest court of appeal for Kenya, Uganda and Tanzania.
The East African Community collapsed in 1977, leading to the dissolution of the East African Court of Appeal. Kenya subsequently established its own Court of Appeal as the apex court, which served as the highest judicial authority for over three decades.
Kenya's landmark Constitution of Kenya 2010, promulgated on 27 August 2010, established the Supreme Court under Article 163 as the apex court of the Republic. This was a transformative moment that restructured the entire Kenyan judiciary and elevated judicial independence to constitutional status.
The Supreme Court of Kenya held its historic inaugural sitting on 20 May 2011 under the leadership of Chief Justice Dr. Willy Mutunga. The court was formally constituted with seven justices and began receiving cases under its original, appellate and advisory jurisdiction.
The Supreme Court determined its first presidential election petition — Raila Amolo Odinga & Another v Independent Electoral and Boundaries Commission & 2 Others — arising from the March 2013 general elections. The court upheld the election of President Uhuru Kenyatta, establishing landmark jurisprudence on electoral law.
In a landmark and internationally acclaimed decision, the Supreme Court (Raila Odinga v IEBC) nullified the August 2017 presidential election results, making Kenya one of the first countries in Africa where a sitting president's election was annulled. The ruling reinforced the rule of law and judicial independence.
The Supreme Court continued its legacy of anchoring constitutional governance, determining the presidential election petition arising from the August 2022 general elections. The court unanimously dismissed the petition challenging the election of President William Ruto, upholding democratic principles.
