Final assessment cannot be reopened through additional grounds; consequential refund relief also fails when jurisdiction is absent.

An appellate tribunal cannot use additional grounds or additional evidence to reopen an assessment order that has already attained finality because it was never challenged within the statutory time. The appellate power applies only to matters actually pending before it and cannot be expanded to a different concluded order. On that basis, consequential refund relief also fails, because refund cannot be granted where the tribunal lacks jurisdiction to disturb the final assessment. The legal point is that a final assessment cannot be indirectly attacked in a later appeal confined to penalty-related issues, and any relief dependent on such reopening is impermissible.

Issues: (i) Whether, in a second appeal, the Tribunal could permit additional grounds challenging an assessment order that had already become final because it was never appealed; (ii) whether the Tribunal could grant refund of tax as consequential relief on the basis of such additional grounds.

Issue (i): Whether, in a second appeal, the Tribunal could permit additional grounds challenging an assessment order that had already become final because it was never appealed.

Analysis: The appeal before the appellate authorities had been confined to the penalty order, while the assessment order had never been challenged at the appropriate stages. Under the statutory scheme, the assessee could appeal against assessment, penalty, or both, but once the assessment was not disputed and the time for challenge had passed, it attained finality. The Tribunal's power to admit additional evidence under the relevant rule was confined to the matters actually pending in appeal and could not be used to reopen a concluded assessment or to expand its appellate jurisdiction to a different order.

Conclusion: The Tribunal was not entitled to admit additional grounds to attack the final assessment order.

Issue (ii): Whether the Tribunal could grant refund of tax as consequential relief on the basis of such additional grounds.

Analysis: Since the challenge to the assessment was not maintainable in the second appeal, the foundation for refund also failed. The Tribunal was acting in appellate jurisdiction over the penalty-related order and not under the statutory refund provision. Consequential relief of refund could not be granted where the assessment had already become final and the Tribunal lacked jurisdiction to disturb it.

Conclusion: The direction for refund of tax was not proper.

Final Conclusion: The reference was answered against the assessee on both questions, and the Tribunal's interference with the concluded assessment was held to be beyond jurisdiction.

Ratio Decidendi: An appellate authority cannot, through additional grounds or evidence, reopen an assessment that has already become final, and consequential refund cannot be granted on the basis of such impermissible reopening.
