Penalty, reassessment, and double taxation limits under VAT law: separate penalty orders and change-of-opinion reopening were struck down.

Penalty under the Tamil Nadu Value Added Tax Act must follow the statutory mode: where Section 27(3) applies, it has to form part of the assessment order, and separate penalty orders are invalid, while separate orders are permissible only under Section 22(5). Reassessment based merely on a change of opinion and internal audit objections, without new material, is not sustainable. Purchase tax cannot be levied again on works-contract transactions already taxed as deemed sales, because the same transaction cannot suffer duplicative levy under the relevant statutory scheme. The impugned orders were therefore unsustainable on all three grounds.

Issues: (i) whether penalty under the Tamil Nadu Value Added Tax Act could be imposed by a separate order instead of as part of the assessment order; (ii) whether reassessment initiated merely on a change of opinion and internal audit objections was permissible; (iii) whether purchase tax could be levied on works contractors on the footing of deemed sales when tax had already been imposed on the same transaction.

Issue (i): Whether penalty under the Tamil Nadu Value Added Tax Act could be imposed by a separate order instead of as part of the assessment order.

Analysis: Penalty was imposed through independent orders. The governing distinction was that penalty could be levied by a separate order only under Section 22(5) of the Tamil Nadu Value Added Tax Act, whereas penalty under Section 27(3) had to form part of the assessment order itself. The principle was treated as settled and applied to the impugned orders.

Conclusion: The penalty orders passed separately were invalid and were set aside.

Issue (ii): Whether reassessment initiated merely on a change of opinion and internal audit objections was permissible.

Analysis: The reopening was not founded on discovery of new material. The record showed that the exercise was undertaken on verification of assessment records and after internal audit objections. Reassessment on a mere change of opinion was treated as impermissible.

Conclusion: The reassessment proceedings were not sustainable.

Issue (iii): Whether purchase tax could be levied on works contractors on the footing of deemed sales when tax had already been imposed on the same transaction.

Analysis: The petitioners were works contractors and purchase tax under Section 12 of the Tamil Nadu Value Added Tax Act had been levied on them. The statutory setting was read with the analogous treatment under Section 7-A(1)(b) of the Tamil Nadu General Sales Tax Act, 1959. Since the transaction had already suffered tax as deemed sales, an additional levy of purchase tax on the same count was not justified.

Conclusion: The purchase tax levy was unsustainable.

Final Conclusion: The impugned orders could not survive on any of the grounds examined, and the writ petitions succeeded with the consequential miscellaneous petitions closed.

Ratio Decidendi: Penalty cannot be imposed by an independent order where the statute requires it to form part of the assessment, reassessment cannot rest on a mere change of opinion, and double taxation on the same works-contract transaction is not permissible when the levy already attaches as deemed sales.
