Explanation 1 to penalty law deems concealment where unexplained additions remain unsubstantiated and penalty is sustained.

Explanation 1 to section 271(1)(c) is treated as a rule of evidence: where an assessee fails to explain, substantiates poorly, or offers a false explanation for additions such as unexplained bank deposits and investments, the amount added is deemed concealed income unless rebutted with cogent, reliable and relevant material showing bona fide disclosure of all material facts. Assessment and penalty proceedings remain distinct, but assessment material may be used in penalty proceedings. The omission to expressly cite the Explanation in the penalty order does not prevent its application when the issue is considered in appellate proceedings. On the stated facts, the assessee did not discharge the burden, so penalty was sustained.

Issues: Whether penalty under section 271(1)(c) was leviable for unexplained bank deposits and investments where the assessee offered no substantiated explanation, and whether Explanation 1 to section 271(1)(c) could be applied even though it was not specifically invoked in the penalty order.

Analysis: Explanation 1 to section 271(1)(c) operates as a rule of evidence. Where the assessee fails to offer an explanation, offers a false explanation, or is unable to substantiate the explanation, the amount added in assessment is deemed to represent concealed income. The burden to rebut that presumption lies on the assessee, and it must be discharged by cogent, reliable and relevant material showing a bona fide explanation and full disclosure of material facts. The fact that assessment and penalty proceedings are distinct does not prevent use of assessment material in penalty proceedings. The omission to specifically mention the Explanation in the penalty order does not bar its application where the issue was raised and considered in appellate proceedings. The assessee did not give any satisfactory explanation for the bank deposits, investments in papers and hotels, or the interest claim linked to marwari loans, and the agreed addition did not by itself wipe out concealment.

Conclusion: Penalty was correctly sustained, and the presumption of concealment was not rebutted; the answer is against the assessee.

Final Conclusion: The appeal failed because the additions represented concealed income and the assessee did not discharge the statutory burden under the penalty provision.

Ratio Decidendi: Under Explanation 1 to section 271(1)(c), once the assessee fails to substantiate the explanation for an addition, concealment is deemed and penalty follows unless the assessee rebuts the presumption with bona fide, fully disclosed, and credible material.
