Politics of Ghana

Politics of Ghana takes place in a framework of a presidential representative democratic republic, whereby the President of Ghana is both head of state and head of government, and of a multi-party system. The seat of government is at Golden Jubilee House. Executive power is exercised by the government. Legislative power is vested in both the government and Parliament. The Judiciary is independent of the executive and the legislature.

The constitution that established the Fourth Republic provided a basic charter for republican democratic government. It declares Ghana to be a unitary republic with sovereignty residing in the Ghanaian people. Intended to prevent future coups, dictatorial government, and one-party states, it is designed to establish the concept of powersharing. The document reflects lessons learned from the abrogated constitutions of 1957, 1960,69, and 1979, and incorporates provisions and institutions drawn from British and American constitutional models. One controversial provision of the Constitution indemnifies members and appointees of the Provisional National Defence Council (PNDC) from liability for any official act or omission during the years of PNDC rule. The Constitution calls for a system of checks and balances, with power shared between a president, a unicameral parliament, a council of state, and an independent judiciary.
