1. Yes. The statutory scheme itself strongly supports the proposition that in certain search-related cases the AO should bypass Section 148A(b) and proceed directly with a notice under Section 148.
Statutory framework
The first proviso to Section 148A states that Section 148A shall not apply in specified cases. Clause (c) covers a situation where:
the AO is satisfied, with prior approval of the PCIT/CIT, that books of account or documents seized/requisitioned in the case of another person pertain to, or information contained therein relates to, the assessee.
This dovetails with Explanation 2(iv) to Section 148, which deems the AO to have information suggesting escapement of income in such cases. Consequently, the AO can issue notice under Section 148 directly, without following the procedure under Section 148A.
Judicial support
While there are not many reported judgments specifically holding that issuance of a 148A(b) notice in a proviso (c)/Explanation 2(iv) case is illegal because the AO ought to have directly issued a Section 148 notice, courts have recognized that the Legislature has expressly excluded Section 148A from such search/requisition cases.
A relevant High Court decision is:
This judgment concerns clause (a) of the proviso (search/requisition in the assessee's own case), but the principle is the same: once a case falls within the categories excluded by the first proviso, compliance with Section 148A is not mandatory.
