SEZ de-notification adjusts notified area following statutory procedure, updating zone boundaries after required approvals. Central Government has de-notified specified parcels within a sector-specific Special Economic Zone for Electronic Hardware and IT/ITES, following a developer proposal, State Government approval and Development Commissioner recommendation, thereby reducing the SEZ's notified land area and recalculating the resultant area; the notification lists the affected survey parcels and confirms statutory prerequisites and rule-based authority for the amendment.
