Tax tribunal jurisdiction and seizure custody limits clarified: criminal investigation must proceed under criminal procedure law.

A tax tribunal may examine actions taken under the sales tax enactment, including investigation for evasion, assessment and penalty, but it has no jurisdiction over FIR-linked criminal investigation or offences triable under the Code of Criminal Procedure and the Indian Penal Code. Once the matter enters the criminal process, police investigation must proceed under the criminal procedure law. Retention of seized books and documents beyond the permissible period is unlawful without a valid extension order or other lawful basis, and the records must be returned. The search and seizure itself was not shown on the stated facts to be illegal.

Issues: (i) whether the Tribunal had jurisdiction to examine the conduct of the Bureau of Investigation and allied police personnel in relation to investigation, FIR and criminal process under the West Bengal Sales Tax Act, 1994 and offences under the Indian Penal Code; (ii) whether the continued retention of seized books of account and documents beyond the permissible period without valid extension was lawful.

Issue (i): whether the Tribunal had jurisdiction to examine the conduct of the Bureau of Investigation and allied police personnel in relation to investigation, FIR and criminal process under the West Bengal Sales Tax Act, 1994 and offences under the Indian Penal Code

Analysis: The Tribunal's jurisdiction under the West Bengal Taxation Tribunal Act, 1987 extends to matters concerning levy, assessment, collection, enforcement and connected actions under the tax statute, but it has no jurisdiction to try proceedings triable under the Code of Criminal Procedure, 1973. The Bureau of Investigation is a statutory creature under the West Bengal Sales Tax Act, 1994 and can exercise only the powers conferred by that Act. Its subordinate police personnel do not become part of the Bureau as independent statutory authority and cannot assume police powers while attached to it. Once an FIR is lodged and the matter moves into the criminal process, further investigation in respect of the cognizable criminal case is governed by the Code of Criminal Procedure, 1973 and the Bureau cannot continue to act as if it were the investigating police authority for that criminal case. At the same time, the Bureau may continue tax-side enquiry or investigation relating to evasion, assessment and penalty under the tax statute, and such actions remain open to judicial scrutiny.

Conclusion: The Tribunal had no jurisdiction over criminal investigation and FIR-related proceedings under the Code of Criminal Procedure, 1973 or in respect of offences under the Indian Penal Code, but it did have jurisdiction to scrutinise actions under the West Bengal Sales Tax Act, 1994 until criminal cognizance and trial in the proper forum.

Issue (ii): whether the continued retention of seized books of account and documents beyond the permissible period without valid extension was lawful

Analysis: The seized records were retained beyond the permissible period and no valid extension order from the Commissioner was produced. The plea that the seizure had become one under criminal process was not supported by any specific order of seizure by the police or competent criminal court. In the absence of a lawful basis to continue retention under the tax statute or the criminal process, the continued custody of the documents could not be justified. However, the search and seizure itself was not shown to be illegal on the facts found.

Conclusion: The continued retention of the seized records was unlawful and their return was directed, but the search and seizure was not held illegal.

Final Conclusion: The applications were disposed of by confining the Bureau and its assisting personnel within the limits of the tax statute, excluding them from further dealing with criminal investigation after FIR, and directing return of the retained documents.

Ratio Decidendi: A statutory tax tribunal may scrutinise actions taken under the tax enactment by its authorities, but once a matter enters the criminal process by FIR and criminal investigation, only authorities acting under the Code of Criminal Procedure can proceed in respect of that criminal case; retention of seized documents must also rest on a valid statutory basis.
