Non-disclosure of reasons for search: recorded reasons and suspicions exempt from disclosure; provisional attachment and valuation procedures introduced. Amendments declare recorded reason to believe and reason to suspect non-disclosable; permit provisional attachment of assessee property during or within sixty days of search with prior senior approval and a six-month automatic lapse; and allow reference to a Valuation Officer for fair market valuation with a sixty-day reporting requirement, while extending the procedural definition of 'execution of an authorisation for search' to the new provisions.
