KANTAMANI VENKATA NARAYANA & SONS vs FIRST ADDITIONAL INCOME-TAX OFFICER,RAJAHMUNDRY

The Supreme Court held that under Section 34 of the Income-tax Act, 1922, a notice for reassessment is valid if the Income-tax Officer has reason to believe that income has escaped assessment due to non-disclosure of material facts by the assessee. The Court clarified that the mere production of books of accounts does not fulfill the duty of full disclosure. It was established that the adequacy of the Officer's belief is not subject to judicial review. The appeals by the assessee were dismissed, affirming the High Court's decision.
