a result of disagreement between Prime-Minister and the Governor-General over the transfer of certain powers and function and there was need for a constitutional change, which resulted in the Republican Constitution of Nigeria 1963. And between 25th May and 26th July 963, there was all-Nigerian constitutional conference held in Lagos, which was summoned by the Prime-Minister. The amendment in 1963 constitution also made provision for the office of the President to take the oath administered by the Chief Justice of Nigeria section 130(1) CFRN There shall be for the federation President, and section 140(2) CFRN 1999, The oath aforesaid shall be administered by the Chief Justice of Nigeria or the person for the time being appointed to exercise the functions of that office. It provided for the National parliament consisting of the House of Representative and the Senate. And the constitution established a consolidated revenue fund where all revenue accruing to the federation should be paid into, and shared among the tiers of government.

In my opinion, issues pertinent to the interest of a zone, region, ethnicity, tribe and not the interest of the country in general that is resolved through a referendum will favour the zone with higher population rate and the other regions, tribes or ethnic groups may combine forces to defeat the purpose of the referendum. And moreover, to organize a constitutional conference involves a lot of money to assemble, accommodate and feed representatives from various states of the federation for as long as the conference will hold, and such conference is usually linked with sentiments, resentment and serious disagreements. In my opinion, the best option for amendment of Nigerian constitution is the most cumbersome process of them all, which is the two-third majority in the Federal Legislature and in State Legislatures as well, because it will produce a
