Section 6 of CGST Act, 2017 – Authorization of officers of State tax or Union Territory tax as proper officer in certain circumstances.
Section 6(2)(b) of CGST Act, 2017 – Where the proper officer under the State Goods and Services Tax Act or the Union Territory Goods and Services Tax Act has initiated any proceedings on a subject-matter, no proceedings shall be initiated by the proper officer under this Act on the same subject- matter.
That in the case of M/S ARMOUR SECURITY (INDIA) LTD. v/s COMMISSIONER, CGST, DELHI EAST COMMISSIONERATE & ANR. The Supreme Court held that a summons issued by the Central GST authorities under section 70 of CGST Act, 2017 does not constitute “initiation of proceedings” under section 6(2)(b) of CGST Act, 2017. Therefore, there is no bar to issuing a summons where the State GST Authorities have already issued a show cause notice on the same subject matter.
Supreme Court issued the following guidelines to be followed in cases where, after the commencement of an inquiry or investigation by one authority, another inquiry or investigation on the same subject matter is initiated by a different authority.
a. Where a summons or a show cause notice is issued by either the Central or the State tax authority to an assessee, the assessee is, in the first instance, obliged to comply by appearing and furnishing the requisite response, as the case may be. We say, so because, mere issuance of a summons does not enable either the issuing authority or the recipient to ascertain that proceedings have been initiated.
b. Where an assessee becomes aware that the matter being inquired into or investigated is already the subject of an inquiry or investigation by another authority, the assessee shall forthwith inform, in writing, the authority that has initiated the subsequent inquiry or investigation.
c. Upon receipt of such intimation from the assessee, the respective tax authorities shall communicate with each other to verify the veracity of the assessee’s claim. We say, so as this course of action would obviate needless duplication of proceedings and ensure optimal utilization of the Department’s time, effort, and resources, bearing in mind that action initiated by one authority enures to benefit of all.
d. If the claim of the taxable person regarding the overlap of inquiries is found untenable, and the investigations of the two authorities pertain to different “subject matters”, an intimation to this effect, along with the reasons and a specification of the distinct subject matters, shall be immediately conveyed in writing to the taxable person.
e. The taxing authorities are well within their rights to conduct an inquiry or investigation until it is ascertained that both authorities are examining the identical liability to be discharged, the same contravention alleged, or the issuance of a show cause notice. Any show cause notice issued in respect of a liability already covered by an existing show cause notice shall be quashed.
f. However, if the Central or the State tax authority, as the case may be finds that the matter being inquired into or investigated by it is already the subject of inquiry or investigation by another authority, both authorities shall decide inter-se which of them shall continue with the inquiry or investigation. In such a scenario the other authority shall duly forward all material and information relating to its inquiry or investigation into the matter to the authority designated to carry the inquiry or investigation to its logical conclusion. We say, so because, the taxable person except for being afforded the statutory protection from duplication of proceedings, otherwise has no locus to claim which authority should proceed with the inquiry or investigation in a particular matter.
g. However, where the authorities are unable to reach a decision as to which of them shall continue with the inquiry or investigation, then in such circumstances, the authority that first initiated the inquiry or investigation shall be empowered to carry it to its logical conclusion, and the courts in such a case would be competent to pass an order for transferring the inquiry or investigation to that authority.
h. If it is found that the authorities are not complying with these aforementioned guidelines, it shall be open to the taxable person to file a writ petition before the concerned High Court under Article 226 of the Constitution of India.
i. At the same time, taxable persons shall ensure complete cooperation with the authorities. It is incumbent upon them to appear in response to a summons and/or reply to a notice.
