Statutory authority limits tax verification powers; a dealer inspection circular was quashed while amended return rules were upheld.

The text examines whether a sales tax application could be rejected for combining connected grievances, and concludes that the objection failed because the complaints formed one integrated scheme. It also discusses the validity of rules 19(1) and 30 of the Bengal Sales Tax Rules, 1941, as amended in 1991, and states that quarterly returns, staged payment, and monthly returns for persistent default were reasonable and constitutionally valid. By contrast, the Commissioner's circular directing regular inspections and verification by officers was found to lack statutory backing and to extend beyond delegated power, so the circular was quashed. The amended payment and return rules were upheld, but the verification circular was struck down.

Issues: (i) Whether the application was bad for clubbing more than one cause of action. (ii) Whether rules 19(1) and 30 of the Bengal Sales Tax Rules, 1941, as introduced by notification dated 8 January 1991, were unreasonable or unconstitutional. (iii) Whether the Commissioner's trade circular dated 4 June 1990, directing regular visits and verification by a team of officers, was ultra vires and liable to be quashed.

Issue (i): Whether the application was bad for clubbing more than one cause of action.

Analysis: The grievance regarding the manner of payment of tax, the filing of returns, and the verification procedure complained of in the circular were found to arise out of one integrated scheme. The reliefs were consequential to one another and were not independent and unrelated causes of action.

Conclusion: The preliminary objection to maintainability was rejected.

Issue (ii): Whether rules 19(1) and 30 of the Bengal Sales Tax Rules, 1941, as introduced by notification dated 8 January 1991, were unreasonable or unconstitutional.

Analysis: Tax liability arises on the completion of sale, and the State is competent to prescribe the manner and intervals of payment having regard to administrative convenience and efficacy of collection. The rules provided for quarterly returns with staged payment within the prescribed time, and the additional consequence of monthly returns for persistent default was treated as a permissible statutory incident of non-payment. The provisions were not shown to violate any constitutional guarantee.

Conclusion: Rules 19(1) and 30 were held to be reasonable and valid, and the challenge to them failed.

Issue (iii): Whether the Commissioner's trade circular dated 4 June 1990, directing regular visits and verification by a team of officers, was ultra vires and liable to be quashed.

Analysis: The circular was not treated as a mere innocuous administrative instruction. The power to inspect, verify, or search dealer premises had to be traced to the statute and exercised within the limits and conditions laid down by law. A regular verification scheme by a visiting team of officers, without statutory backing and outside the expressly conferred powers, amounted to an assumption of authority beyond the Commissioner's jurisdiction and to a colourable exercise of power.

Conclusion: The trade circular was quashed.

Final Conclusion: The challenge succeeded only in respect of the impugned circular, while the amended rules governing payment and return requirements were upheld as lawful.

Ratio Decidendi: An executive circular that creates a coercive verification regime affecting dealers' rights must be supported by express statutory authority, and a tax authority cannot, by administrative instruction, expand its powers beyond the limits fixed by the statute.
