The present book seeks to re-evaluate the theory of basic structure at the theoretical level in the light of spurt of writings on unamendability of the foundational principles of the Constitution in the recent times from the larger canvas of democratic constitutionalism. Therefore, this book is as much an exercise in political theory as in constitutional jurisprudence. After straddling both the domain of case law and theoretical exploration, the book argues that the features of basic structure delineated by the Supreme Court on case to case basis in the last 50 years correspond with the Idea of India. The book has privileged the identity grounded in the definition of citizenship in the Constitution by subordinating the identity rooted in scripted categories. By raising the question, whether the doctrine of basic structure has eroded or entrenched the democracy?, the book concludes that the overarching values of the Constitution identified by the Supreme Court, far from diminishing, have strengthened democracy................................??Evidently, this book is the product of humongous industry of the author. A well conceptualised work on a boiling topic, being published at a time when we are celebrating Golden jubilee of the verdict, handed down by 13 wise Judges of the Supreme Court of India, in Kesavanand Bharati. The lucidity with which the author has untangled the nuanced aspects of the doctrine of basic structure and explicated about the future of the doctrine, makes this book a must read. I wish all the success for this book and its author and hope they will get the recognition it deserves.?? -(Justice A.M. Khanwilkar, former judge,Supreme Court)
