Works contract deduction for pipes retained in installed irrigation system upheld under sales tax law

PVC and HDPE pipes purchased from registered dealers and used in executing a drip irrigation works contract retained their identity despite being cut and fixed during installation. The Madras HC held that, where goods are used in substantially the same form in which they were purchased and the assessee proves such use in the works contract, deduction under Section 3-B(2)(b) of the Tamil Nadu General Sales Tax Act, 1959 cannot be denied merely because the goods became part of an installed system. The Tribunal's contrary view was rejected and the writ petitions were allowed.

Issues: Whether the petitioner was entitled to deduction under Section 3-B(2)(b) of the Tamil Nadu General Sales Tax Act, 1959 in respect of PVC and HDPE pipes used in executing the drip irrigation works contract.

Analysis: The dispute related to assessment years when there was no specific schedule entry for drip irrigation systems. The pipes used in the installation were held to retain their identity and not to lose their character merely because they were cut and fixed for use in the irrigation system. The Court held that the petitioner had discharged the burden of proving that the goods were purchased from registered dealers and used in the execution of the works contract in the same form in which they were purchased. The benefit of deduction under Section 3-B(2)(b) was therefore available, and the Tribunal's contrary conclusion was not accepted.

Conclusion: The petitioner was entitled to deduction under Section 3-B(2)(b) of the Tamil Nadu General Sales Tax Act, 1959 for the pipes used in the works contract, and the writ petitions were allowed.

Ratio Decidendi: Where goods purchased from registered dealers are used in the execution of a works contract in substantially the same form and continue to retain their identity, deduction under Section 3-B(2)(b) cannot be denied merely because they form part of an installed system.
