Revisional jurisdiction cannot overturn a plausible assessment on charitable deductions where donation conditions are met.
Tribunals held that Explanation 2 limiting CSR expenditure as a business deduction operates within the business income chapter and does not ipso facto bar claims under the donations regime; specific statutory exceptions indicate Parliament's choice to restrict only certain items. A mandatory CSR outlay does not automatically negate donation character where there is no material return, provided donee approval and documentary evidence are established. On revisional power, section 263 cannot be invoked to overturn an assessing officer's tenable, precedent backed view where enquiries were made; revision is justified only if the AO's conclusion is legally untenable or there was no inquiry.
