Check-post verification cannot require extra clearance certificates where the statute permits only alternative documents.

Under the Assam General Sales Tax Act, 1993 and the Assam Agricultural Income-tax Act, 1939, check-post officers could verify goods and documents, but could not insist on agricultural income-tax clearance certificates or sales tax clearance certificates for tea transit where the substantive law did not require them. Section 46(7) was treated as allowing alternative documents, while rule 43(7)(j) and rule 33(2) were held inconsistent to the extent they demanded additional or multiple certificates. The article also notes that subordinate rules cannot enlarge the statutory requirement, and that section 46(4) was stated not to offend Article 19(1)(g).

Issues: (i) Whether, under the Assam General Sales Tax Act, 1993 and the Assam Agricultural Income-tax Act, 1939, the authorities could insist on tax clearance certificates for movement of tea through check posts or barriers and detain trucks for non-production of such certificates; (ii) Whether rule 43(7)(j) and rule 33(2) of the Assam General Sales Tax Rules, 1993 could validly require production of sales tax clearance certificates and more than one document for compliance with section 46 of the Act.

Issue (i): Whether, under the Assam General Sales Tax Act, 1993 and the Assam Agricultural Income-tax Act, 1939, the authorities could insist on tax clearance certificates for movement of tea through check posts or barriers and detain trucks for non-production of such certificates.

Analysis: The statutory scheme showed no provision in the Assam Agricultural Income-tax Act, 1939 for issuance of an agricultural income-tax clearance certificate as a condition for transporting goods. Likewise, under section 46 of the Assam General Sales Tax Act, 1993, the power at check posts was limited to examining goods and documents to ascertain whether tax had been paid or properly accounted for. The Court accepted that the documents contemplated by section 46(7) were alternative in nature and that the authorities could not insist on a clearance certificate not contemplated by the substantive enactment.

Conclusion: The insistence on agricultural income-tax clearance certificates and sales tax clearance certificates for transit of tea was impermissible and the petitioners succeeded on this issue.

Issue (ii): Whether rule 43(7)(j) and rule 33(2) of the Assam General Sales Tax Rules, 1993 could validly require production of sales tax clearance certificates and more than one document for compliance with section 46 of the Act.

Analysis: Section 46(7) specified documents in the alternative, whereas rule 43(7)(j) was framed in a conjunctive manner and additionally included tax clearance certificates. Rule 33(2), inserted later, also required production of a tax payment certificate at check posts. The Court held that subordinate legislation could not override the Act, and where there was inconsistency, the Act would prevail. It further held that the power under section 72 did not support the sub-delegation attempted through rule 43(7)(j)(vi), making that part also beyond the rule-making power.

Conclusion: Rule 43(7)(j) and rule 33(2), to the extent they required sales tax clearance certificates or more than one document, were inconsistent with the Act and could not be enforced against the petitioners.

Final Conclusion: The writ petitions were allowed, and the authorities were restrained from insisting on agricultural income-tax clearance certificates and sales tax clearance certificates at check posts or barriers until the law is suitably amended, while the Court also clarified that section 46(4) itself did not offend Article 19(1)(g) of the Constitution of India.

Ratio Decidendi: Where the substantive Act contemplates alternative documents for check-post verification, subordinate rules cannot enlarge the requirement by compelling additional certificates or documents not authorised by the Act.
