Branches
Lagos State has a classic tripartite separation of powers system consisting of the executive, the legislature and the judiciary.
The executive is headed by the governor who exercises executive power upon his or her election. Headed by a Speaker, the legislature consists of a forty-member House of Assembly vested with legislative power while the judiciary through the Lagos State Judiciary is charged with the exercising of judicial power.
