Dr. D.D. Basu is not known in legal realms by his name alone but it is because of his maturity of understanding, excellence of elucidation and simplicity of expression which ranks him at the top amongst Indian Authors known, read and acclaimed throughout India and abroad. Amongst many of his outstanding works and Comparative Constitutional Law and Comparative Federalism have always been recognized as unparallel and incomparable works with any other book on the subject, much because of the in-depth study of special features and incidents of a Federal Constitution, from the standpoint of comparative law in addition to the exhaustive and analytical study of the theme and thought of Comparative Federalism. The eloquences of the earlier edition was superb much because of excerpts from Constitutions of almost all the developed and developing countries with cross references of decisions on the intricacies of Comparative Constitutional Law and Comparative Federalism as interpreted by numerous Courts at national and international levels. After discussing the broad features of a written Constitution in the first volume of this series on Comparative Constitutional Law, we now take up the special features and incidents of a Federal Constitution, from the standpoint of comparative law. Obviously, the broad issues involved in the federal system have already been outlined in the Author's book on Comparative Constitutional Law by way of introduction to a written Constitution which is federal in nature. In the present one the author has dealt with the general features of federalism. Political Science classified Constitutions as unitary and federal, from the organizational standpoint, i.e., from the standpoint of distribution of governmental powers, vertically, in a system of 'dual government'.
