Investigation and search powers require prior intimation to the Development Commissioner unless Central Government authorises officers to act without it. Agencies or officers specified under the Act may, on written reasons that a notified offence has been or is likely to be committed, carry out investigation, inspection, search or seizure in a SEZ or Unit only after prior intimation to the Development Commissioner; agencies or officers not so specified require prior approval of the Development Commissioner. An officer authorised by the Central Government is permitted to conduct investigation, inspection, search or seizure without prior intimation or approval.
