Sales tax legislative competence limits confiscation powers for goods in transit when prescribed documents are absent.

Entry 54 of List II permits State legislation on sales tax and includes only ancillary or incidental machinery needed to prevent tax evasion. Section 42(1) and 42(2) of the Madras General Sales Tax Act were treated as preventive machinery, but section 42(3) went further by authorising seizure, confiscation and penalty for goods in transit, including self-owned goods and personal luggage, merely for non-production of prescribed documents. That drastic confiscatory power was held to rest on an unwarranted assumption of completed intra-State sale and tax liability, and was not fairly comprehended within the sales tax field. The provision was therefore beyond legislative competence and invalid.

Issues: Whether the power of seizure, confiscation, and imposition of penalty under section 42(3) of the Madras General Sales Tax Act, 1959, was within the legislative competence conferred by Entry 54 of List II of the Seventh Schedule to the Constitution of India and could be sustained as incidental or ancillary to the power to levy sales tax.

Analysis: Entry 54 authorises State legislation on taxes on the sale or purchase of goods, and such a taxing entry includes ancillary and incidental provisions necessary to prevent evasion of tax. The machinery provisions in section 42(1) and section 42(2) were directed to that preventive purpose. However, section 42(3) went further by empowering seizure and confiscation of any goods in transit, and by exposing even self-owned goods or personal luggage to forfeiture merely because the prescribed documents were not produced. The provision proceeded on an unwarranted assumption that goods carried across the border had been sold within the State and that tax liability had necessarily arisen. Such a drastic confiscatory power was not fairly and reasonably comprehended within the legislative field of sales tax, nor could it be treated as merely incidental or ancillary to tax collection.

Conclusion: The confiscatory and penalty power under section 42(3) was beyond legislative competence and could not be upheld as ancillary to the power to levy sales tax.

Final Conclusion: The appeals were dismissed, and the invalidity of the confiscatory provision was affirmed.

Ratio Decidendi: A taxing entry authorising legislation on sales tax permits only such ancillary or incidental provisions as are necessary to prevent evasion of tax, and a confiscatory power extending to goods in transit merely for want of prescribed documents exceeds that field of competence.
