SEZ approval extensions limited to demonstrable development progress and conditional restructurings requiring continuity and disclosure. Board of Approval addressed SEZ procedural governance: extensions of formal approvals and LoPs were permitted only upon demonstrable development progress or justified reasons and within time-limited increments; co-developer approvals were authorised subject to standard SEZ Act/Rules and lease-term limits; changes in shareholding, ownership or name were allowed conditioned on continuity of operations, fulfilment of eligibility and security clearances, compliance with Revenue/Company/SEBI rules, immediate financial disclosure to Member (IT), CBDT and tax authorities, and adherence to State laws; lapsed formal approvals were cancelled where no extension was sought.
