Issues Involved:
1. Divisibility of the works contract.
2. Entitlement to exemption certificates under Rule 10A and 10B.
3. Applicability of the 46th Constitutional Amendment and its impact on the definition of "sale."
4. Retrospective application of the exemption notification dated 29.03.2001.
5. Availability of alternative remedies.

Detailed Analysis:

1. Divisibility of the Works Contract:
The petitioner-company challenged the assessment orders which treated the contract as divisible into two parts: one for the supply of pipes and the other for laying them. The court upheld the Deputy Commissioner(Appeals) and the Appellate Authority's findings that the contract was divisible. The supply of pipes was deemed a sale, subject to sales tax, while the laying of pipes was considered a service. This was based on the work orders and the nature of the contract, which indicated separate components for supply and services.

2. Entitlement to Exemption Certificates:
The petitioner sought exemption certificates for the work orders under Rule 10A and 10B, arguing that the contracts were indivisible. However, the Tax Assessing Authority and the Appellate Authority rejected this claim, stating that the contracts were divisible and the supply of pipes constituted a sale. The court agreed with this assessment, noting that the supply of pipes fell within the definition of 'sale' under the Rajasthan Sales Tax Act, 1954.

3. Applicability of the 46th Constitutional Amendment:
The court discussed the impact of the 46th Constitutional Amendment, which added clause 29A to Article 366, defining 'sale' to include the transfer of property in goods involved in the execution of a works contract. This amendment allowed states to levy sales tax on the value of materials used in works contracts. The court referenced the Supreme Court's decisions in Builders Association of India and Gannon Dunkerley, which clarified that a works contract could be taxed for the value of goods involved, even if the contract was indivisible.

4. Retrospective Application of the Exemption Notification:
The petitioner argued for the retrospective application of the exemption notification dated 29.03.2001. However, the court held that the notification, which categorized laying of pipelines with material as a works contract, was clarificatory and applied prospectively from the year 2001-2002. The petitioner's assessment for the year 1999-2000 could not benefit from this notification.

5. Availability of Alternative Remedies:
The court emphasized the availability of alternative remedies, suggesting that the petitioner should have approached the Rajasthan Tax Board for further appeals. The court was not inclined to interfere with the findings of the lower authorities, given the alternative remedy available. Consequently, the writ petition was dismissed on this ground.

Conclusion:
The court upheld the findings of the lower authorities, confirming that the works contract was divisible and subject to sales tax on the supply of pipes. The exemption notification could not be applied retrospectively, and the petitioner was advised to seek alternative remedies through the Rajasthan Tax Board. The appeals and the writ petition were consequently dismissed.
