“lack of inquiry”

The Commissioner cannot revise an assessment order under Section 263 merely because they hold a different opinion or believe a deeper inquiry was warranted if the Assessing Officer has applied their mind and conducted some inquiry. Revision under Section 263 is permissible only in cases of a complete lack of inquiry or non-application of mind by the Assessing Officer, not for merely inadequate inquiry.

When an assessee provides the identity and address of a creditor or investor for a cash credit or share capital under Section 68, the burden shifts to the Department to establish lack of genuineness or creditworthiness, requiring it to conduct further inquiries; mere non-compliance by third parties to summons cannot be the sole basis for an adverse inference against the assessee.

The Commissioner cannot revise an assessment under Section 263 merely because the assessment order does not explicitly reflect an inquiry, or because the Commissioner holds a different opinion. An inquiry, even if considered inadequate, or an assessment based on a plausible view by the Assessing Officer after due examination, does not automatically make the order erroneous or prejudicial to the interests of the revenue.

An assessment order is erroneous and prejudicial to the interest of revenue if the Assessing Officer fails to make proper inquiries before accepting the assessee's statements or claims. The Commissioner can revise such an order under Section 263 without conducting further inquiries himself.

The Commissioner cannot invoke Section 263 for an assessment merely because of an inadequate inquiry by the Assessing Officer, provided there was some inquiry or the record demonstrates application of mind, as this constitutes a mere difference of opinion.

Before revising an assessment order under Section 263, the CIT/PCIT must conduct their own inquiries or verifications to establish that the Assessing Officer's order is erroneous and unsustainable in law, rather than merely directing further inquiry or pointing out the AO's lack of inquiry.

An assessment order cannot be deemed erroneous and prejudicial to the interest of revenue under Section 263 if the Assessing Officer conducted an inquiry and applied their mind during the original assessment, as Explanation 2 to Section 263 does not permit unending inquiries by the revisional authority.

A Commissioner can revise an assessment order under Section 263 if it is erroneous and prejudicial to the interests of the revenue. This includes cases where the Assessing Officer fails to make further inquiries before accepting the assessee's statements in the return.
