(2) The person, from whom records seized or frozen, shall be entitled to obtain copies of records.
(3) On the expiry of the period specified under sub-section (1), the records shall be returned to the person from whom such records were seized or whose records were ordered to be frozen unless the Adjudicating Authority permits retention or continuation of freezing of such records beyond the said period.
(4) The Adjudicating Authority, before authorising the retention or continuation of freezing of such records beyond the period specified in sub-section (1), shall satisfy himself that the records are required for the purposes of adjudication under section 8.
(5) After passing of an order of confiscation [or release under sub-section (5) or sub-section (6) or sub-section (7) of section 8 or section 58B or sub-section (2A) of section 60], the Adjudicating Authority shall direct the release of the records to the person from whom such records were seized.
(6) Where an order releasing the records has been made by the Court [Adjudicating Authority under sub-section (5) of section 21], the Director or any other officer authorised by him in this behalf may withhold the release of any such record for a period of ninety days from the date of [receipt of] such order, if he is of the opinion that such record is relevant for the appeal proceedings under this Act.]
