“lack of enquiry”

For revision under Section 263, the Assessing Officer's order must be both erroneous and prejudicial to the interests of the revenue; if either condition is not met, the revisionary jurisdiction cannot be invoked. An order is not erroneous merely because the Assessing Officer did not record the details of enquiries conducted, provided due enquiries were made.

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.

For exercising revisional jurisdiction under Section 263, the Commissioner must first find that the Assessing Officer's order is erroneous and unsustainable in law, as this is a condition precedent. An order is not erroneous merely because two views are possible, or if the Commissioner disagrees with the Assessing Officer's permissible view, or to simply remit the matter for further enquiries.

An assessment order is not erroneous and prejudicial under Section 263 merely because the Assessing Officer did not record an enquiry and its satisfactory answer in the assessment order, provided such an enquiry was conducted. For revision under Section 263, the Commissioner must also provide the assessee an opportunity of being heard and examine their explanation.

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.
