Finality of assessment bars reassessment only when the same issue is reopened; distinct matters may still be reassessed.

Finality attached to an assessment confirmed on appeal bars reassessment under section 19(1) of the M.P. General Sales Tax Act, 1958 only where the later proceeding seeks to reopen the same matter already finally decided under section 38(6). The decisive inquiry is whether the issue proposed for reassessment is identical to the earlier adjudicated controversy, not the label of the proceeding. If the matter is the same, the assessing authority lacks jurisdiction; if it is distinct, reassessment remains competent. The Tribunal must first record a clear finding on identity or difference of the matter before sustaining or invalidating the reassessment.

Issues: Whether reassessment under section 19(1) of the M.P. General Sales Tax Act, 1958 was barred where the matter had already attained finality under section 38(6) of the Act, and whether the Tribunal had to determine if the reassessment concerned the same matter or a distinct matter.

Analysis: The finality attached to an assessment order confirmed in appeal prevents reopening under section 19(1) if the later proceedings relate to the same matter already adjudicated. The crucial inquiry is not the label of the proceedings but whether the issue sought to be reopened is identical to the issue finally decided earlier. If the reassessment concerns the same controversy, the assessing authority lacks jurisdiction; if it concerns a different matter, the reassessment is competent. The Tribunal had to record a clear finding on identity or difference of the matter before the reassessment could be sustained or invalidated.

Conclusion: Reassessment is barred if the matter is the same, and permissible if the matter is distinct and different. The Tribunal must determine that factual issue and proceed accordingly.

Final Conclusion: The reference was answered in a qualified manner and the matter was sent back to the Tribunal for a finding on whether the two proceedings involved the same issue or a different one.

Ratio Decidendi: Finality of an assessment confirmed in appeal bars reassessment only when the reassessment seeks to reopen the very same matter already finally decided; jurisdiction to reopen exists where the later proceeding concerns a different matter.
