Search assessment classification upheld where belated returns cannot cure non-disclosure under the income-tax block assessment scheme

Section 158BB(1)(c) of the Income-tax Act is explained as a special block-assessment rule for search cases that operates notwithstanding the general return-filing provisions. The provision treats income not disclosed by the due date as undisclosed income and does not permit a person searched after non-disclosure to rely on a belated return under section 139(4). The analysis reasons that filing a return is the legally relevant mode of disclosure and that advance tax payment alone does not amount to disclosure. On that basis, the classification is said to be rational and non-discriminatory within the search-assessment class, and the provision is upheld as constitutionally valid.

Issues: Whether section 158BB(1)(c) of the Income-tax Act, 1961, which treats income not returned by the due date as undisclosed income in block assessments, is unconstitutional for excluding the benefit of a belated return filed under section 139(4).

Analysis: Chapter XIV-B was enacted to provide a special procedure for search cases and operates notwithstanding other provisions of the Act. The legislative classification targets assessees whose undisclosed income is detected in search, and differential treatment of such persons is permissible if founded on a rational basis. Filing an income return is the legally relevant mode of disclosure, and payment of advance tax does not by itself establish disclosure. The provision does not create discrimination within the class subjected to search assessments, nor does it confer a right on a person who has already failed to disclose income and has been searched to rely on a belated return filed after detection.

Conclusion: Section 158BB(1)(c) is valid and constitutional; the challenge fails.

Final Conclusion: The writ petition was rejected and the impugned block-assessment provision was upheld.

Ratio Decidendi: A special search-assessment provision that denies post-search reliance on a belated return is constitutionally valid if it rests on a rational classification of assessees who have failed to disclose income and applies uniformly within that class.
