The government has proposed an amendment to the Income tax act from April 1, 1962 that would allow it to tax transactions like Vodafone's acquisition of Hutch. Harish Salve, Senior Advocate, Supreme Court of India told NDTV Profit that the statements that no fresh demands will be made against Vodafone are just half-truth. "A retrospective law is a blow to investor confidence," he said adding that even the government does not believe that it is making clarificatory petition.
