The highest court of appeal under the Nigerian independence constitution was the Judicial Committee of the Privy Council. This was because Nigeria was still a member of the British Commonwealth of Nations and therefore, the highest court of appeal was the Privy Council in London, UK. The Privy Council was responsible for hearing appeals from all parts of the Commonwealth including Nigeria. However, the Privy Council was replaced by the Supreme Court of Nigeria as the highest court of appeal in 1963, after Nigeria became a republic.
