The Republican Constitution of 1963; All you need to know

The Republican Constitution of 1963 was essentially the 1960 independence constitution rewritten with some minor modifications, and it came into operation on the 1st of October, 1963. It was in a bid to change the dominance of external affairs of Nigeria by Britain that a new constitution call the Republican Constitution of 1963 was proposed and adopted in 1963. With is constitution, the Queen ceased to be the Head of state and the executive function of the various units of the federation was no longer vested on her. She was also no longer a part of the legislative house of the federation.
  Under the new constitution, an elected president was substituted for the Queen as the Head of State. The judicial Service Commission was abolished and the president was empowered to appoint judges of the Supreme Court and those of the High Court of Lagos on the advice of the prime minister.
Thus, the Supreme Court now became the final court of appeal in Nigeria. The power to declare any federal or regional law unconstitutional if it is inconsistent with any provision of the constitution (judicial review) was granted to the Federal Supreme Court.
   The emergency powers were also conferred on the federal government to declare state of emergency on any part of the country whenever there was war or serious crisis. Again, the constitution stipulated the procedure for the creation of new regions and the adjustment in the existing regional boundaries. It was in line with this procedure that the-Mid-western region was created in August, 1963.
