Court rules Methanol taxed at 12% under Sales Tax Acts, rejecting 7% rate. Res judicata not applicable.

The High Court concluded that Methanol and Methyl Alcohol are the same commodity based on scientific and common parlance definitions. The court held that the correct tax rate for Methanol should be 12% plus 1% under the U.P. Sales Tax Act and the Central Sales Tax Act, overturning the Tribunal's decision to tax it at 7% plus 1%. The principle of res judicata was deemed inapplicable in tax matters, emphasizing adherence to prescribed tax rates over prior inconsistent assessments. The court emphasized that in tax classification, both scientific definitions and common parlance supported the conclusion that Methanol and Methyl Alcohol are synonymous.

Issues Involved:
1. Whether Methanol and Methyl Alcohol are two names of the same commodity or different goods.
2. Applicability of the rate of tax on Methanol under the U.P. Sales Tax Act and the Central Sales Tax Act.
3. Relevance of the principle of res judicata in tax matters.
4. The significance of the common parlance test versus scientific or technical definitions in tax classification.

Detailed Analysis:

1. Methanol and Methyl Alcohol as the Same Commodity:
The primary issue was to determine if Methanol and Methyl Alcohol are the same or distinct commodities. The court examined definitions from the OXFORD dictionary and the Random Dictionary and Directory of Plastics, both of which describe Methanol as another name for Methyl Alcohol. Additionally, a Text Book on Organic Chemistry by Arun Bahl and B.S. Bahl was referenced, explaining that Methanol and Methyl Alcohol are two names for the same chemical compound (CH3OH). The court concluded that Methanol and Methyl Alcohol are indeed the same commodity, both in chemical and physical properties.

2. Applicability of Tax Rates:
For the assessment year 1975-76, the Assistant Commissioner (Assessment) Sales Tax, Ghaziabad, initially taxed Methanol at 12% plus 1% as per Notification No. ST-II-3203/X-1012-1972 dated 29th September, 1972. The Tribunal later reduced the rate to 7% plus 1%, treating Methanol as an unclassified item. The High Court, upon review, found that the correct rate should be 12% plus 1% as Methanol and Methyl Alcohol are the same. The court also clarified that under Section 8(2)(b) of the Central Sales Tax Act, the applicable rate for inter-state sales should be the higher of 10% or the rate under the State Act, which in this case is 12% plus 1%.

3. Principle of Res Judicata in Tax Matters:
The court addressed the department's argument that the principle of res judicata does not apply in tax matters. It was noted that the previous High Court judgment did not provide reasons for treating Methanol and Methyl Alcohol as distinct commodities and thus did not serve as a binding precedent. The court emphasized that the applicable tax rate should be based on the prescribed rate under the relevant notification rather than previous erroneous assessments.

4. Common Parlance Test versus Scientific Definitions:
The court discussed the relevance of the common parlance test in tax classification, as argued by the assessee. The assessee cited examples and case laws suggesting that common parlance should prevail over scientific definitions. However, the court found that in this case, both scientific definitions and common usage in dictionaries and textbooks supported that Methanol and Methyl Alcohol are the same. Therefore, the common parlance test did not alter the conclusion.

Conclusion:
The High Court quashed the Tribunal's order dated 6th February 1990, which had treated Methanol as an unclassified item taxable at 7% plus 1%. The court ruled that Methanol and Methyl Alcohol are the same commodity and should be taxed at 12% plus 1% as per the relevant notification. The revision was allowed, and the court ordered no costs.
