Issues Involved:
- Whether the 'hot mix material' transferred in a works contract is to be taxed under the Haryana Value Added Tax Act, 2003 at the prescribed rates of its constituents or at the general rate under the residuary clause.

Detailed Analysis:

Issue 1: Taxation of 'Hot Mix Material' in Works Contracts

The core issue revolves around the appropriate tax rate for 'hot mix material' used in works contracts. The appellant, engaged in road and bridge construction, contested the assessment order that taxed 'hot mix material' under the residuary clause at a general rate.

Legal Framework:
- Article 286 of the Constitution of India restricts the imposition of state taxes on sales or purchases that occur outside the state or in the course of import/export.
- Section 7 of the Haryana Value Added Tax Act, 2003 specifies tax rates for different categories of goods, with a general rate for unspecified items.

Judicial Precedents:
1. Builders Association of India v. Union of India (1989):
- Upheld the constitutional validity of the 46th Amendment, which introduced the concept of deemed sales in works contracts.
- Emphasized that the transfer of property in goods involved in works contracts is subject to the same restrictions as any other sale under Article 286.

2. Gannon Dunkerley & Co. v. State of Rajasthan (1993):
- Clarified that even in indivisible works contracts, there is a deemed sale of goods involved.
- Allowed state legislatures to prescribe a uniform tax rate for goods used in works contracts, distinct from rates for individual goods.

3. Larsen and Toubro Limited v. State of Karnataka (2014):
- Summarized that for a deemed sale in a works contract, there must be a transfer of property in goods, which can be taxed even if the goods lose their identity.
- Reinforced that the nature of the contract (whether for sale or service) does not affect the applicability of sales tax on materials used.

4. State of Karnataka v. Durga Projects Inc. (2018):
- Rejected the notion that a residuary entry could imply a uniform rate for goods in works contracts.
- Highlighted that specific rates for goods in schedules take precedence over general rates.

Court's Analysis:
- The court noted that the 46th Amendment and subsequent judicial interpretations established a deemed sale for materials in works contracts.
- The State of Haryana had not prescribed a uniform rate for materials in works contracts. Therefore, materials like cement, bitumen, and rori should be taxed at their prescribed rates, not the general rate.
- The court rejected the state's argument that the transformation of materials into 'hot mix material' negates their individual tax rates, emphasizing that the loss of identity does not prevent the materials from being taxed as goods.

Conclusion:
- The court concluded that the 'hot mix material' used in works contracts should be taxed according to the rates prescribed for its constituents, not under the general rate of the residuary clause.
- The appeal was allowed, setting aside the orders that taxed 'hot mix material' at the general rate.

Final Judgment:
The appeals were allowed, and it was held that the goods transferred in the execution of works contracts should be taxed at the rates prescribed for the constituents of the 'hot mix material'.
