Kenya · Overview

The legal system of Kenya

A common-law system transformed by the 2010 constitution, which created 47 devolved counties, a Supreme Court, and one of the strongest bills of rights in Africa. Kadhis' courts have constitutional standing for Muslim personal status. Kenyan courts have annulled a presidential election and struck down constitutional amendment attempts, making this an unusually active constitutional jurisdiction.
