Sec. 263 of Income Tax Act, 1961 – Revision – Every loss of revenue as a consequence of an order of the AO cannot be treated as prejudicial to the interests of the Revenue, for example, when an ITO adopted one of the courses permissible in law and it has resulted in loss of revenue; or where two views are possible and the ITO has taken one view with which the Commissioner does not agree, it cannot be treated as an erroneous order prejudicial to the interests of the Revenue unless the view taken by the ITO is unsustainable in law – HARI OM STONES [2020] 423 ITR 198 (RAJ)
