Composite sales tax assessment vitiated by inseparable illegal levy; refund limitation and Section 80 notice both upheld.

Limitation for refund suits depended on the nature of the payment: advance payments of sales tax not made under protest or in satisfaction of a revenue demand fell under Article 62 of the Limitation Act, so the refund suits were within time. A Section 80 CPC notice was valid because it substantially informed the Government of the illegal tax levy complained of, and reference to an appeal did not vitiate it. Applying sale of goods principles, property passed on delivery to the railway where no reservation of disposal was proved, so the sales in categories 2 and 3 were taxable within Madras. Because the assessment was composite and inseparably mixed taxable and non-taxable turnover, the illegal portion vitiated the whole assessment.

Issues: (i) whether the suits for refund of sales tax were barred by limitation; (ii) whether the notice under Section 80 of the Code of Civil Procedure was invalid; (iii) whether the sales in categories 2 and 3 were completed within the province so as to be taxable; (iv) whether the assessments, being composite and partly based on illegal levy, were invalid in toto.

Issue (i): whether the suits for refund of sales tax were barred by limitation.

Analysis: Section 18 of the Madras General Sales Tax Act was held inapplicable to suits for refund of tax illegally levied, as it was confined to damages and compensation. Article 16 of the Limitation Act also did not apply because the payments were advance payments and were neither made under protest nor in satisfaction of a claim made by revenue authorities. The claims were treated as falling under Article 62 of the Limitation Act, and the suits were within time.

Conclusion: The limitation defence failed and the suits were not time-barred.

Issue (ii): whether the notice under Section 80 of the Code of Civil Procedure was invalid.

Analysis: The notice sufficiently informed the Government of the nature of the proposed action, namely illegal levy of tax. The difference between stating mistake in the notice and coercion in the plaint did not go to the substance of the cause of action. The pendency of an appeal did not postpone the accrual of cause of action, and the notice was not vitiated merely because it referred to the appeal or contemplated suit only if relief was not granted in appeal.

Conclusion: The notice under Section 80 was valid.

Issue (iii): whether the sales in categories 2 and 3 were completed within the province so as to be taxable.

Analysis: The situs of sale depended on when property passed to the buyer. Applying the Sale of Goods Act provisions on intention, appropriation, and reservation of the right of disposal, the Court held that where railway receipts were made out to the buyer and no reservation of disposal was proved, property passed on delivery to the railway and the sales were completed within Madras. Retention of railway receipts or routing them through bankers did not by itself show reservation of title. The contracts were ordinary sales and were distinguishable from c.i.f. and f.o.b. contracts.

Conclusion: The sales in categories 2 and 3 took place within the province and were liable to tax.

Issue (iv): whether the assessments, being composite and partly based on illegal levy, were invalid in toto.

Analysis: The assessments comprised a single indivisible sum including both taxable and non-taxable turnovers. Once part of the assessment was found illegal, the whole assessment could not be severed and sustained, and the de minimis principle did not save the residue.

Conclusion: The assessments were invalid in toto.

Final Conclusion: The appeals succeeded and the cross-objections failed, with the result that the assessments were set aside as wholly invalid and the taxation authorities were left at liberty to proceed afresh in accordance with law.

Ratio Decidendi: In a composite tax assessment, if taxable and non-taxable items are inseparably blended and one part is illegally included, the entire assessment is vitiated; for refund suits, the applicable limitation depends on the true nature of the payment, and a Section 80 notice is valid if it substantially apprises the Government of the illegal levy complained of.
