A Show Cause Notice Issuing Demands Contrary To A Finalized Advance Ruling Is Bad In Law
Issue
Whether a tax authority can validly issue a demand Show Cause Notice under Section 73 of the CGST Act when the underlying tax liability has already been conclusively decided in favor of the taxpayer by a finalized Advance Ruling that was never challenged by the Revenue.
Facts
-
The respondent tax authority issued a Show Cause Notice (SCN) to the petitioner, demanding a specific tax or Input Tax Credit (ITC) amount under Section 73 of the Act.
-
Instead of filing a routine reply before the adjudicating officer, the petitioner directly approached the High Court to challenge the foundational validity of the notice.
-
The petitioner contended that the grounds raised in the impugned SCN directly conflicted with an Advance Ruling dated April 11, 2022, which had been issued on the very same matter.
-
The relevant Advance Ruling had been accepted by the respondent authority, was never appealed or assailed in any higher forum, and had legally attained absolute finality between the parties.
Decision
-
Held, that an Advance Ruling is legally binding on both the applicant and the jurisdictional tax authorities by virtue of Section 103, unless it is overturned on appeal or declared void under Section 104.
-
Held, that because the Advance Ruling in this case had attained absolute finality between the parties, the subsequent Show Cause Notice issued by the respondent was completely without foundation.
-
Held, that given the binding existence of the Advance Ruling, the impugned notice is unsustainable in law and must be treated as non-est (legally non-existent).
-
Held, that when the fate of a tax notice is entirely apparent on the face of the record, there is no legal justification to force the petitioner to undergo the rigorous process of a departmental adjudication.
-
Held, that the impugned Show Cause Notice is accordingly quashed and set aside, deciding the matter entirely in favor of the assessee.
Key Takeaways
-
Binding Nature of Advance Rulings: Section 103 of the CGST Act explicitly dictates that an Advance Ruling is binding on the field formations in respect of the specific applicant. The Revenue cannot unilaterally bypass this statutory mandate by issuing a subsequent demand notice on the same subject.
-
Bypassing Alternative Remedies: While courts typically require taxpayers to exhaust internal administrative remedies by replying to an SCN, a writ court will step in immediately to quash a notice if it is ex-facie without jurisdiction or flies in the face of a finalized legal order.
-
Finality Cuts Both Ways: Once the department chooses not to appeal an adverse ruling within the prescribed timelines, that ruling becomes the absolute law of the case for that specific taxpayer, and the department cannot later attempt a back-door review via Section 73 or 74 proceedings.
