The Charter is of seminal importance to understand the U.N. and its agencies. It is a bold step towards making the world a family of Nations, an attempt to ensure that wars do not scourge the world, an endeavour to make this world peaceful, cooperative and worth living. The book gives in brief the historical background of the U.N. Charter. It also presents how the Court is constituted and functions. The text introduces to the readers those distinguished Indians who sat as judges in the Court. In its present form, the text is useful to students of Political Science, International Organisation and of Law. It will be of great help to all candidates appearing for Civil Service examinations conducted by U.P.S.C. and State Public Service Commissions.
