Chidambaram said the Swiss government had proposed revision of its domestic laws for providing information under the tax treaties, which would have enabled the European nation to provide information to India in the HSBC cases even in respect of the so-called stolen data.
In 2011, the Indian government received the names of 782 Indians who had accounts with HSBC.
“However, it is learnt that the proposed revision did not take place due to strong political opposition in Switzerland,” he said.
