Retrospective validation of tax investigation powers and limited confidentiality under voluntary disclosure scheme upheld.

A retrospective validating amendment to the Bengal Finance (Sales Tax) Act, 1941 inserted section 19A, recognised the Bureau of Investigation within the commercial tax framework, and deemed prior appointments, delegations, searches and seizures to have been made under the amended Act, thereby curing the earlier defect in authority. On that basis, officers in the Bureau were competent to exercise delegated search and seizure powers. The confidentiality attached to declarations under the voluntary disclosure scheme in section 68 of the Finance Act, 1965 protected disclosure by public servants and production before court, but it did not bar sales tax authorities from lawfully requisitioning relevant particulars under their own statutory powers.

Issues: (i) Whether the Bureau of Investigation and the appointments and delegations made in connection with it were valid and could support the search and seizure of dealers' records under the Bengal Finance (Sales Tax) Act, 1941; (ii) Whether clause (8) of section 68 of the Finance Act, 1965 barred the sales tax authorities from calling for particulars relating to a voluntary disclosure made under that scheme.

Issue (i): Whether the Bureau of Investigation and the appointments and delegations made in connection with it were valid and could support the search and seizure of dealers' records under the Bengal Finance (Sales Tax) Act, 1941.

Analysis: The amended statutory scheme inserted section 19A of the Bengal Finance (Sales Tax) Act, 1941 retrospectively and provided for the constitution of the Bureau of Investigation as part of the commercial tax set-up. The Special Officer was made competent to exercise the powers of an Additional Commissioner, and persons appointed in the Bureau were made competent to exercise the powers otherwise exercisable by them under the Act. The validating provision also deemed prior appointments, directions, searches, seizures, notifications and proceedings to have been made under the amended Act, thereby removing the defect on which the earlier decision had proceeded. On that footing, the officers posted in the Bureau were lawfully empowered to exercise the delegated powers of search and seizure.

Conclusion: The Bureau and the officers acting under it were validly constituted and empowered, and the search and seizure were lawful.

Issue (ii): Whether clause (8) of section 68 of the Finance Act, 1965 barred the sales tax authorities from calling for particulars relating to a voluntary disclosure made under that scheme.

Analysis: The confidentiality protection attached to declarations under the voluntary disclosure scheme operated against disclosure by public servants and production before a court, but it did not create a blanket prohibition against lawful requisition by authorities acting under another statute. Where the sales tax law authorised the Commissioner and duly delegated officers to require production of books, documents and information from a dealer, the demand for relevant particulars was not illegal merely because the materials related to a confidential disclosure made elsewhere.

Conclusion: The confidentiality clause did not bar the sales tax authorities from lawfully calling for the relevant particulars.

Final Conclusion: The challenge to the legality of the Bureau and the seizure failed, while the confidentiality objection also failed; accordingly, the State's appeal succeeded and the connected appeal by the assessees failed.

Ratio Decidendi: A retrospective validating amendment may cure the absence of prior statutory authority by deeming the impugned body, appointments, delegations and acts to have been made under the parent Act, and a confidentiality clause in one fiscal scheme does not override lawful powers conferred by another statute to requisition relevant records.
