Recognised stock exchange notification requires SEBI approval, supporting documents, and Central Government decision within the prescribed period. Procedure for notification of a recognised stock exchange requires an application to the Member (Income Tax), supported by SEBI derivatives approval, current rules and bye-laws, confirmation of rule 4 conditions, and any other information the exchange wishes to place before the Central Government. The Central Government may seek additional material and must then either notify the exchange or reject the application within six months from the end of the month of receipt. The notification remains effective until SEBI approval is withdrawn or expires, or the notification is rescinded.
