Double taxation and new evidentiary conditions rejected where subcontractor turnover was already assessed separately.

Turnover already assessed and exempted in the hands of sub-contractors could not be included again in the main contractor's taxable turnover for additional sales tax, because the works contract provision did not create a principal-agent relationship and taxing the same value twice would amount to double taxation. The Tribunal's insistence on production of Form XXXVII-B was also unsustainable, since that requirement had not been raised by the revenue in appeal and could not be introduced as a new condition outside the pleaded controversy. The substantive and procedural points were therefore resolved in favour of the assessee.

Issues: (i) Whether payments made by the main contractor to sub-contractors, whose turnover had been treated as exempt and assessed at the sub-contractors' end, could still be included in the main contractor's taxable turnover for levy of additional sales tax. (ii) Whether the Tribunal could insist upon production of Form XXXVII-B as a condition for granting such exemption, when that requirement was not the basis of the revenue's appeal.

Issue (i): Whether payments made by the main contractor to sub-contractors, whose turnover had been treated as exempt and assessed at the sub-contractors' end, could still be included in the main contractor's taxable turnover for levy of additional sales tax.

Analysis: The assessment records showed that the sub-contractors' turnover had been accepted as eligible for exemption and the revenue's case before the Tribunal proceeded only on the footing that the main contractor acted as a principal and the sub-contractors as agents. The Court accepted the Tribunal's conclusion that Section 3-B dealt with works contracts and did not create a principal-agent relationship. Once the sub-contractors' turnover had been properly brought to tax at their end, the same turnover could not again be included in the main contractor's turnover for the purpose of additional sales tax. The attempt to tax the same value again would amount to double taxation.

Conclusion: The payments made to sub-contractors could not be included in the main contractor's taxable turnover for levy of additional sales tax, and the finding was in favour of the assessee.

Issue (ii): Whether the Tribunal could insist upon production of Form XXXVII-B as a condition for granting such exemption, when that requirement was not the basis of the revenue's appeal.

Analysis: The requirement of Form XXXVII-B was never raised by the revenue before the Tribunal, nor was it part of the grounds urged in appeal. The Court held that introducing such a condition after deciding the controversy on merits travelled beyond the scope of the appeal and was therefore without jurisdiction. Since the revenue had not disputed that the sub-contractors were registered dealers or that taxes had been paid at their end, the Tribunal's insistence on the form had no foundation in the pleaded controversy.

Conclusion: The direction to produce Form XXXVII-B was without jurisdiction and unsustainable, in favour of the assessee.

Final Conclusion: The revisions were allowed and the Tribunal's order was set aside to the extent it imposed an unwarranted condition, with the substantive issues decided in favour of the assessee.

Ratio Decidendi: Where the turnover of sub-contractors has already been assessed at their end, the same amount cannot again be included in the main contractor's taxable turnover for additional sales tax, and a Tribunal cannot impose a new evidentiary condition that was never in issue in the appeal.
