“erroneous and prejudicial”

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.

Under Section 263, an assessment order is not erroneous and prejudicial to the interest of the revenue merely because the Principal Commissioner disagrees with the Assessing Officer's (AO) view, particularly if the AO has adopted one of two permissible views in law, unless that view is completely unsustainable. If due inquiries were made, the AO's order does not become erroneous solely because the fact of inquiries was not recorded.

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.

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 Revenue's interests if the Assessing Officer accepts a sum offered as income by an assessee, even when that sum was not actually earned, thereby allowing revision under Section 263.

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.

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.
