Special tax bureau limits and statutory sanction: IPC investigation was beyond authority, and cognizance without commissioner approval failed.

A special tax-enforcement bureau under the West Bengal Sales Tax Act, 1994 was held to be confined to investigating tax evasion and connected malpractices, and it could not investigate distinct Indian Penal Code offences disclosed in the FIR. Those IPC offences had to be handled by the regular police under the Code of Criminal Procedure, and the bureau officers were not treated as superior police officers for that purpose. The document also states that cognizance of Sales Tax Act offences required prior sanction of the Commissioner; because no valid sanction covered the petitioners, the chargesheet, cognizance order and arrest warrant could not stand, although the FIR itself was not quashed.

Issues: (i) Whether the Bureau of Investigation under the West Bengal Sales Tax Act, 1994 had authority to investigate offences under the Indian Penal Code when the FIR disclosed both sales tax offences and cognizable IPC offences. (ii) Whether the chargesheet and cognizance against the petitioners were valid in the absence of sanction by the Commissioner under the Sales Tax Act.

Issue (i): Whether the Bureau of Investigation under the West Bengal Sales Tax Act, 1994 had authority to investigate offences under the Indian Penal Code when the FIR disclosed both sales tax offences and cognizable IPC offences.

Analysis: The statutory scheme of Section 7 of the West Bengal Sales Tax Act, 1994 confines the Bureau's powers to investigation and enquiry into alleged or suspected evasion of tax and malpractices connected therewith, along with the ancillary powers specifically conferred by the Act. Sections 65 to 73 and related provisions regulate the machinery for search, seizure, inspection and tax-enforcement measures under that Act. Those powers do not extend to investigation of offences falling solely under the Indian Penal Code. Once the FIR disclosed distinct IPC offences, the investigation of those offences had to be carried out by the regular police under the Code of Criminal Procedure. The officers attached to the Bureau were not treated as superior police officers for the purpose of exercising powers under Sections 36 and 156 of the Code in relation to IPC offences.

Conclusion: The Bureau had no authority to investigate the IPC offences, and the investigation by the Bureau in that respect was without jurisdiction.

Issue (ii): Whether the chargesheet and cognizance against the petitioners were valid in the absence of sanction by the Commissioner under the Sales Tax Act.

Analysis: Section 88(12) of the West Bengal Sales Tax Act, 1994 bars cognizance of offences under the Act without the previous sanction of the Commissioner. The sanction on record was granted only in favour of other accused persons and did not extend to the petitioners. No valid sanction existed for prosecuting the petitioners, and the Bureau had not conducted any lawful investigation against them in respect of the sales tax offences. In those circumstances, the submission of chargesheet against the petitioners and the order taking cognizance could not be sustained. However, the FIR itself disclosed cognizable offences and therefore was not liable to be quashed.

Conclusion: The chargesheet and the order taking cognizance, including the arrest warrant against the petitioners, were invalid and were set aside, but the FIR was not quashed.

Final Conclusion: The revisional application succeeded only to the extent of setting aside the cognizance order and arrest warrant against the petitioners, while the criminal proceeding was left open for further lawful action in accordance with law.

Ratio Decidendi: A special tax-enforcement agency constituted under a fiscal statute cannot investigate or prosecute IPC offences beyond the statutory limits of its authority, and cognizance under the fiscal statute is impermissible without the requisite statutory sanction.
