(2) Where any Chief Commissioner or Commissioner, in consequence of information in his possession, has reason to suspect that any books of account or other documents, money, bullion, jewellery or other valuable article or thing in respect of which an officer has been authorised by the Director General or Director or any other Chief Commissioner or Commissioner or any such Joint Director or Joint Commissioner as may be empowered in this behalf by the Board to take action under clauses (i) to (vi) of sub-section (1) are kept in any building, place, vessel, vehicle or aircraft not mentioned in the authorisation under sub-section (1), such Chief Commissioner or Commissioner may, notwithstanding anything contained in section 8, authorise the said officer to take action under any of the clauses aforesaid in respect of such building, place, vessel, vehicle or aircraft.

(3A) The authorised officer may, where it is not practicable to seize any books of account, other documents, money, bullion, jewellery or other valuable article or thing, for reasons other than those mentioned in the second proviso to sub-section (1), serve an order on the owner or the person who is in immediate possession or control thereof that he shall not remove, part with or otherwise deal with it except with the previous permission of such officer and such officer may take such steps as may be necessary for ensuring compliance with this sub-section. Explanation.—For the removal of doubts, it is hereby declared that serving of an order as aforesaid under this sub-section shall not be deemed to be seizure of such books of account, other documents, money, bullion, jewellery or other valuable article or thing under clause (iv) of sub-section (1). (4) The authorised officer may, during the course of the search or seizure, examine on oath any person who is found to be in possession or control of any books of account or other documents, articles or things including money and any statement made by such person during such examination may thereafter be used in evidence in any proceeding under this Act. Explanation.—For the removal of doubts, it is hereby declared that the examination of any person under this sub-section may be not merely in respect of any books of account, other documents or assets found as a result of the search, but also in respect of matters relevant for the purposes of any investigation connected with any proceedings under this Act.

(6A) An order under sub-section (3A) shall not be in force for a period exceeding sixty days from the date of the order, except where the authorised officer, for reasons to be recorded in writing by him, extends the period of operation of the order beyond sixty days, after obtaining the approval of the Director or, as the case may be, Commissioner for such extension: Provided that the Director or, as the case may be, Commissioner shall not approve the extension of the period for any period beyond the expiry of thirty days after the completion of the proceedings under this Act in respect of the years for which the books  of account, other documents, money, bullion, jewellery or other valuable articles or things are relevant. (7) The person from whose custody any books of account or other documents are seized under sub-section (1) or sub-section (2) may make copies thereof, or take extracts therefrom, in the presence of the authorised officer or any other person empowered by him in this behalf at such place and time as the authorised officer may appoint in this behalf. (8) Where the authorised officer has no jurisdiction over the person referred to in clause (a) or clause (b) or clause (c) of sub-section (1), the books of account or other documents seized under that sub-section shall be handed over by the authorised officer to the Assessing Officer having jurisdiction over such person within a period of fifteen days of such seizure and thereupon the powers exercisable by the authorised officer under sub-section (6) or sub-section (7) shall be exercisable by such Assessing Officer.

(11) The provisions of the Code of Criminal Procedure, 1973 (2 of 1974), relating to searches shall apply, so far as may be, to searches under this section. (12) The Board may make rules in relation to searches or seizure under this section; and in particular and without prejudice to the generality of the foregoing power, such rules may provide for the procedure to be followed by the authorised officer—               (i)           for obtaining ingress into any building, place, vessel, vehicle or aircraft to be searched where free ingress thereto is not available;               (ii)          for ensuring the safe custody of any books of account or other documents seized.
