Section 115BBE of the Income Tax Act

When two equally plausible interpretations of a taxing provision are possible, or when conflicting views exist from non-jurisdictional High Courts, the interpretation that favors the assessee must be adopted.

The Revenue is entitled to look behind the apparent form of a transaction to discover its true nature, applying the test of human probabilities and surrounding circumstances. If transactions defy logic or are unnatural, they can be treated as bogus, even if supported by some documentation, especially in cases of cash credits or unexplained investments.

Tax authorities must judge evidence using the test of human probabilities and consider the apparent as real until there are reasons to believe it is not. They can rely on circumstantial evidence and the preponderance of probabilities to determine the genuineness of transactions.

Taxing statutes are presumed to operate prospectively unless a clear contrary intention for retrospective application is evident. The law applicable for determining tax liability is that which stands on the first day of the assessment year, following the principle that law looks forward, not backward (lex prospicit non respicit).

Corroborative evidence is essential to support evidence found on third-party premises, and an assessment cannot be based on suspicion, surmises, or conjecture.

An addition to income cannot be made merely on the basis of a difference in valuation of assets or a Valuation Officer's report without establishing actual understatement of consideration or the source of unexplained funds through proper enquiry. The Assessing Officer must conduct proper enquiry and satisfy the conditions for making such additions.

The assessee bears the onus of proving the source and nature of any sum of money or receipt found to have been received by them. If the assessee fails to satisfactorily explain the receipt, the Income-tax Officer is entitled to treat it as taxable income.

Approval under Section 153D of the Income Tax Act is mandatory for assessment orders in search cases. While elaborate reasons for approval are not required, the approving authority must provide some indication that it has examined the draft orders and found them to meet the requirements of law.

Where an assessee maintains regular books of account, and these books are not rejected or found defective by the Assessing Officer, any cash deposits or available cash shown in the cash book, if sufficient to cover the transaction, cannot be treated as unexplained income or an addition under sections 68 or 69A.

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.
