Limited Scrutiny scope expanded to permit examination of law enforcement information with prior administrative approval, with assessee notification. Assessing Officers in Limited Scrutiny cases from CASS 2017 and 2018 may examine issues arising from credible information provided by law enforcement, intelligence or regulatory agencies with prior administrative approval of the Principal CIT/CIT. The expansion is limited to those specific issues and does not convert the case into Complete Scrutiny. The AO must record reasons, obtain Pr. CIT/CIT approval, intimate the assessee, and may invoke Section 144A and ensure Review/Inspection to prevent fishing and roving enquiries.
