Revisional action fails when its legal basis is later reversed, and the resulting reassessment cannot survive.

A suo motu revision under Rule 80 of the Orissa Sales Tax Rules was described as unsustainable because it rested entirely on an earlier Tribunal view that was later displaced by a Division Bench ruling. The later ruling clarified that incentive notification benefits operated in addition to statutory tax concessions and required reassessment without treating the incentive exemption as excluded. With the legal foundation for revision removed, the consequential reassessment could not stand and the revisional action was set aside.

Issues: Whether the suo motu revision and consequential reassessment made under Rule 80 of the Orissa Sales Tax Rules could be sustained when the authority's foundation had been displaced by a later binding decision.

Analysis: The impugned revision was founded on an earlier Tribunal view that a dealer could not simultaneously claim concessional tax treatment and exemption benefits. That basis was later reversed by a Division Bench decision, which held that the benefit under the incentive notification was in addition to the statutory concessions and directed reassessment without reference to the exemption under the incentive policy. Once that legal foundation ceased to survive, the very premise for initiating revision under Rule 80 was rendered unsustainable.

Conclusion: The suo motu revision could not be sustained and the reassessment was liable to be quashed.

Final Conclusion: The writ petition succeeded and the impugned revisional action was set aside.

Ratio Decidendi: Where a revisional action rests entirely on a legal position that is later reversed, the revision cannot survive and the consequential reassessment must fall with it.
