Withdrawal of recognition for a stock exchange after failure to corporatise and demutualise within the statutory timeframe. Withdrawal of recognition is effected because the Delhi Stock Exchange Limited failed to complete corporatisation and demutualisation within the prescribed timeframe under the notified corporatisation and demutualisation scheme, thereby invoking sub section (2) of section 5 of the Securities Contracts (Regulation) Act, 1956 and resulting in a Central Government notification withdrawing the recognition previously granted under section 4.
