The Supreme Court on Friday stayed an order of the Central Information Commission which held that the National Stock Exchange of India (NSEI) is a 'public authority' under the Right to Information Act.A bench of justices Vikram Nath and Sandeep Mehta agreed to hear a petition filed by the NSEI and sought responses from the Central Information Commission and others within four weeks.The NSEI challenged the July 1 verdict of a division bench of the Delhi High Court.The high court's division bench had dismissed the NSEI's appeal against its single judge's April 2010 decision which ruled that NSEI qualified as a 'public authority' under section 2(h) of the RTI Act.The stock exchange had challenged the June 2007 CIC order before the single judge and asserted that it was not a 'public authority' under the RTI Act.Citizens can enforce their right to ask for information only from a 'public authority' under the RTI Act.The high court's division bench had observed that if the body is owned, controlled or substantially financed by the appropriate government, it would qualify as a 'public authority'."The single judge holds, in the impugned judgment, that the NSEI is controlled by the appropriate government, and we agree," the division bench had said.
