UNION OF INDIA & ORS. vs TATA IRON & STEEL CO. LTD.

The Supreme Court ruled that the classification of a manufactured product as 'skelp' or 'strip' under the Central Excises and Salt Act, 1944, is crucial for determining the applicable excise duty. The Court held that the taxing authorities must apply identifiable tests in their classification to avoid arbitrary assessments. The Delhi High Court's decision favoring the respondent was upheld, leading to the conclusion that the product should be classified as 'strip', thereby subjecting it to a lower excise duty.
