Section 69 of the Income Tax Act

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).

An assessee must be given an opportunity to cross-examine third parties whose statements are relied upon for adverse findings. Failure to provide this opportunity is a serious flaw rendering the order a nullity.

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.

Income tax additions cannot be sustained merely on the basis of uncorroborated statements or allegations. The Revenue must bring on record sufficient material and allow the assessee to produce evidence to prove such additions.

If the Assessing Officer or appellate authority does not rebut the facts stated in an affidavit, those facts are binding on the tax authorities.

A mistake apparent from the record under Section 154 must be an obvious and patent error, not one that requires a long and elaborate process of reasoning or where two opinions are conceivable. Rectification under Section 154 is not permissible for re-examining issues already considered or requiring detailed re-computation.

A statement made by an assessee under Section 131 during search proceedings, without any corroborating incriminating material found during the search, cannot solely constitute incriminating evidence for making additions in assessments under Section 153A or 153C.

An unsatisfactory explanation for an amount credited in the books does not automatically result in it being deemed as the assessee's income under Section 68. The initial onus is on the assessee to prove the identity, creditworthiness, and genuineness of the transaction.

The onus lies on the assessee to satisfactorily explain the source and nature of any unexplained cash or credit entries; if they fail to do so, the amount is treated as taxable income. The Income Tax Department is not required to locate the exact source of such funds, and this principle applies even if Section 68 is not strictly invoked.

Proceedings under Section 153A of the Income Tax Act are not confined solely to incriminating material found during a search, and the Assessing Officer can assess total income for the relevant years.
