Change of opinion cannot justify reopening where actuarial material was already disclosed and no tangible suppression was shown.

Reassessment was held unsustainable where the original scrutiny assessment had already considered the actuarial report and related material, including the negative reserve. Reopening on the same material amounted to a mere change of opinion, not discovery of new facts. The record also showed no tangible material indicating that the assessee failed to fully and truly disclose material facts necessary for assessment. In the absence of such material, the statutory conditions for reopening were not met, and the addition based on the negative reserve did not survive once the reassessment was invalidated.

Issues: (i) Whether the reassessment proceedings were valid when the original assessment had already considered the actuarial material and the reopening was based on the same material; (ii) Whether the Assessing Officer had any tangible material to show failure by the assessee to fully and truly disclose material facts necessary for assessment.

Issue (i): Whether the reassessment proceedings were valid when the original assessment had already considered the actuarial material and the reopening was based on the same material.

Analysis: The return had been processed and scrutiny assessment completed after the actuarial report and related material were furnished by the assessee. The reassessment was founded on the same actuarial material already on record, namely the negative reserve shown in the report. Reopening on that basis amounted to a fresh view on the manner of computation rather than discovery of new material.

Conclusion: The reopening was invalid and was based on a change of opinion.

Issue (ii): Whether the Assessing Officer had any tangible material to show failure by the assessee to fully and truly disclose material facts necessary for assessment.

Analysis: The actuarial report showing the negative reserve had been furnished during the original proceedings, and the assessment order itself referred to that report. The record did not show any omission by the assessee or any new tangible material suggesting suppression of facts. In the absence of such material, the statutory requirement for reassessment was not satisfied.

Conclusion: No tangible material existed to support reopening, and there was no failure of full and true disclosure by the assessee.

Final Conclusion: The reassessment could not be sustained, and the Revenue's challenge failed; the addition based on negative reserve did not survive once the reassessment itself was held invalid.

Ratio Decidendi: Reassessment under section 147 cannot be sustained on a mere change of opinion where the material relied upon was already disclosed in the original proceedings and no tangible material shows failure of full and true disclosure by the assessee.
