India's Supreme Court has said that the practice of illegal funnelling of wealth overseas by Indians is a "pure and simple theft of national money". The court also asked what the government was doing to retrieve the illegal money in foreign banks. US-based group Global Financial Integrity has said that India has lost more than $460bn in such illegal flight of capital since Independence. It said the illicit outflows increased after economic reforms began in 1991. The report also said that almost three-quarters of the illegal money that comprises India's underground economy ends up outside the country. India's underground economy has been estimated to account for 50% of the country's GDP - $640bn at the end of 2008. Wednesday's remarks by the Supreme Court came when it was hearing a petition filed by a former federal Law Minister Ram Jethmalani and others on the alleged inaction of the government in bringing back illegal money parked overseas by rich Indians and companies. In response, India's Solicitor-General Gopal Subramaniam submitted a sealed cover containing 16 names of individuals and companies who had accounts with a Liechtenstein-based bank. "This is all the information you have or you have something more! We are talking about the huge money. It is a plunder of the nation," remarked Justice B Sudershan Reddy.
