Change of opinion bars reassessment when full disclosure was made and no new tangible material emerged.

Reassessment under sections 147 and 148 was treated as impermissible where the original assessment under section 143(3) had been completed on the basis of full disclosure of primary facts and no new tangible material had emerged. The reopening relied only on material already available to the Assessing Officer, so it amounted to a mere change of opinion rather than a valid jurisdictional basis for reassessment. The presumption under section 114(e) of the Indian Evidence Act supported the view that the original assessment had been made after due consideration of the disclosed facts. The notice under section 148 was therefore quashed.

Issues: Whether reassessment under sections 147 and 148 of the Income-tax Act, 1961 was valid when the original assessment had been completed under section 143(3), the assessee had disclosed the relevant primary facts, and no new tangible material had emerged.

Analysis: The assessee had placed the relevant particulars regarding provision for doubtful debts, advances, and diminution in the value of investments in the return materials and computation details filed during the original assessment. The reasons recorded for reopening referred only to material already available before the Assessing Officer at the original stage. In such circumstances, the reassessment could not be sustained on the basis of a mere different view of the same material, and the presumption under section 114(e) of the Indian Evidence Act, 1872 supported the conclusion that the original assessment had been made after due consideration of the disclosed facts. Reopening on the same material, without any new tangible basis, amounted to a change of opinion.

Conclusion: Reassessment was invalid and the notice under section 148 was quashed; the issue was decided in favour of the assessee.

Ratio Decidendi: Where an assessee has made full and true disclosure of primary facts in an assessment completed under section 143(3), reassessment cannot be initiated on the same material in the absence of new tangible material, as such reopening amounts to a change of opinion.
