Book excerpt: In writing this authoritative source of reference for students of Law and legal practitioners in Nigeria and elsewhere, Sir Udo Udoma realised a youth ambition he developed as a Reid's Professor's Prizeman of the Law School of the University of Dublin, Trinity College, Dublin, Ireland, in the 1940s, to one day write a book on Constitutional Law. HISTORY AND THE LAW OF THE CONSTITUTION OF NIGERIA is the result of his study and analysis of Nigeria's constitutional history that involved research work of great magnitude into the various nooks and crannies in which the origin of the country, Nigeria, lies buried. It allows the reader to understand and appreciate some of the problems that still confront Nigeria, as a country in the continent of Africa, particularly those of unity and stability.
