Rectification after immunity and unexplained expenditure rulings limit use of sections 154, 69C and 115BBE.

Section 154 cannot be used to materially alter an assessment after immunity under section 270AA has brought the matter to finality; a rectification power is confined to correcting patent mistakes and cannot rewrite assessed loss into taxable income. An estimated disallowance of expenses already recorded in the books does not, by itself, make the expenditure unexplained under section 69C, because that provision applies only where the source of expenditure remains unproved. On that basis, section 115BBE was also inapplicable. The rectification and its affirmation were treated as unsustainable in law.

Issues: (i) Whether the Assessing Officer could invoke rectification under section 154 of the Income-tax Act, 1961 to alter the tax consequence of an assessment after granting immunity under section 270AA; (ii) Whether an ad hoc disallowance of expenditure already recorded in the books could be treated as unexplained expenditure under section 69C and subjected to section 115BBE.

Issue (i): Whether the Assessing Officer could invoke rectification under section 154 of the Income-tax Act, 1961 to alter the tax consequence of an assessment after granting immunity under section 270AA.

Analysis: The assessment had attained statutory finality after the assessee accepted the order and immunity was granted under section 270AA. The rectification proceeding did not correct a patent mistake but sought to rewrite the assessment by changing assessed loss into taxable income under section 115BBE. Such a course exceeded the limited scope of section 154 and defeated the legislative object of section 270AA, which is to bring quietus to accepted assessments and reduce litigation.

Conclusion: The rectification under section 154 was not sustainable and could not be used to unsettle an assessment that had attained finality under section 270AA.

Issue (ii): Whether an ad hoc disallowance of expenditure already recorded in the books could be treated as unexplained expenditure under section 69C and subjected to section 115BBE.

Analysis: The addition was made only as an estimated disallowance of part of the expenses debited in the profit and loss account. Expenditure disclosed in the books and reflected in audited accounts does not become unexplained expenditure merely because supporting details were not fully furnished. Section 69C applies to expenditure whose source remains unexplained, not to a routine estimated disallowance under normal computation provisions. Since the foundation for section 69C was absent, section 115BBE could not be applied.

Conclusion: The disallowance could not be characterised as unexplained expenditure under section 69C, and section 115BBE was inapplicable.

Final Conclusion: The impugned rectification and the appellate affirmation thereof were held unsustainable in law, and the assessee succeeded in the appeal.

Ratio Decidendi: Where an assessment has attained finality after immunity under section 270AA is granted, section 154 cannot be used to materially alter the assessment, and an expense already recorded in books cannot be treated as unexplained expenditure under section 69C merely because it was estimatedly disallowed for want of supporting details.
