The Citizenship Amendment Bill presented in Indian Parliament in 2016 has passed both the houses after prolonged debate in December 2019 and got approved by the President. Even then no Rules have been formulated for the implementation. Violent opposition and protest countrywide against the act creating provision for the refugees to acquire Indian citizenship have been observed. The book deals with definition of citizenship, relevant provision in Constitution, previous Citizenship Act and its subsequent changes till the most recent amendments. It throws light on the nature and direction of conflicting interests and demands of different groups. The highly informative yet lucid discussion of the complicated subject is expected to satisfy the readers and instigate them to think seriously.
