The Calcutta High Court has reaffirmed the foundational principle of administrative consistency in tax matters, holding that revenue authorities cannot adopt contradictory positions regarding the classification of identical goods across different financial years once they have accepted a binding appellate order. This decision reinforces legal certainty for exporters and underscores the duty of state agencies to adhere to their own adjudicative outcomes.
Background & Facts
The Dispute
The petitioner, Frese nius Kabi Oncology Limited, exported bulk drugs classified under serial no. 47A of the Central Government’s Notification No. 4/2006-CE dated March 01, 2026, by the Revisional Authority in an order dated November 18, 2019. This classification subjected the goods to higher tax liability. The petitioner contested this, arguing that the same goods were correctly classified under serial no. 47B in other proceedings.
Procedural History
- November 18, 2019: Revisional Authority classified goods under serial no. 47A.
- June 26, 2024: CESTAT, in a separate but factually identical case, held that the goods fall under serial no. 47B and allowed the petitioner’s appeal.
- May 1, 2025: The Adjudicating Authority, in yet another proceeding involving the same goods and period, accepted the CESTAT order and classified the goods under serial no. 47B.
- January 3, 2025: CGST authorities confirmed in writing that the CESTAT order dated June 26, 2024, had been accepted.
- February 20, 2026: The High Court issued the impugned order, correcting a typographical error (‘SESTAT’ to ‘CESTAT’) in a prior order.
Relief Sought
The petitioner sought quashing of the November 18, 2019 order and a declaration that the goods must be classified under serial no. 47B, consistent with the binding CESTAT ruling and the Adjudicating Authority’s subsequent acceptance.
The Legal Issue
The central question was whether tax authorities are bound by their own acceptance of a CESTAT order classifying identical goods under a specific tariff head, and whether they may later adopt a contradictory classification in a different tax period without any change in facts or circumstances.
Arguments Presented
For the Petitioner
The petitioner relied on M/s. Radhasoami Satsang, Saomi Bagh, Agra v. Commissioner of Income Tax (1992) 1 SCC 659 to argue that administrative consistency is a facet of natural justice and non-arbitrariness under Article 14 of the Constitution. It was contended that once the Revenue accepted the CESTAT order in a parallel proceeding and applied it to classify the same goods under serial no. 47B, it could not revert to a conflicting classification in a prior proceeding merely because of a different financial year. The petitioner emphasized that the goods, their composition, and their intended use remained unchanged.
For the Respondent
The respondents argued that the order under challenge - dated November 18, 2019 - predated the CESTAT order and the subsequent acceptance by the Adjudicating Authority. They contended that the principle of res judicata or estoppel does not apply to administrative decisions across different assessment years, and that each tax period must be independently adjudicated. They further claimed that the acceptance of the CESTAT order in a later proceeding did not invalidate the earlier classification, which was based on the law as understood at that time.
The Court's Analysis
The Court examined the doctrine of consistency in administrative action, drawing heavily from Radhasoami Satsang. It held that while each assessment year is technically distinct, the identity of the goods and the legal framework governing their classification remain constant. Where the facts are identical and the statutory provisions unchanged, a change in classification by the same authority constitutes an arbitrary and discriminatory exercise of power.
"To permit the respondents to take a contradictory stand in respect of the same goods merely because they relate to a different tax period would be to sanction arbitrariness and violate the principle of equality under Article 14."
The Court noted that the Adjudicating Authority’s order dated May 1, 2025, explicitly recorded the acceptance of the CESTAT ruling, thereby demonstrating that the Revenue had internally acknowledged the correctness of the 47B classification. To uphold the 2019 order would render this acceptance meaningless and undermine the authority of appellate tribunals.
The Court further observed that the doctrine of consistency is not a technicality but a constitutional imperative in tax administration, ensuring predictability and fairness. The respondents’ reliance on the temporal sequence of orders was rejected as legally insufficient to justify inconsistency.
The Verdict
The petitioner succeeded. The Court held that once tax authorities accept a CESTAT order classifying goods under a specific tariff head, they are bound by that classification for identical goods in other assessment years, absent a change in facts or law. The November 18, 2019 order was set aside, and the goods were deemed to fall under serial no. 47B.
What This Means For Similar Cases
Classification Must Be Uniform Across Periods
- Practitioners may now invoke administrative consistency to challenge contradictory classifications of identical goods across financial years.
- Revenue authorities must document and justify any deviation from prior classifications, even if the assessment year differs.
CESTAT Orders Bind Lower Authorities
- Acceptance of a CESTAT order by any subordinate authority (e.g., Adjudicating Authority) constitutes a binding administrative admission.
- Petitioners should file applications under Section 129A of the CGST Act to formally record such acceptance and use it as evidence in pending proceedings.
Estoppel Applies in Tax Matters
- The doctrine of promissory estoppel and equitable estoppel now have clearer application in indirect tax disputes.
- Taxpayers should preserve all correspondence where authorities acknowledge appellate rulings, as these may serve as conclusive evidence of waiver or admission.
