PLASMAC MACHINE MANUFACTURING CO. PVT.LTD. vs COLLECTOR OF CENTRAL EXCISE, BOMBAY.

The Supreme Court dismissed the appeal regarding the classification of 'Tie Bar Nuts' under the Central Excises and Salt Act, 1944, specifically under Section 3 and the First Schedule, Items Nos. 52 and 68. The Court held that if an article is classifiable under a specific item, it should not be classified under a residuary item, affirming the Tribunal's decision to classify Tie Bar Nuts under Tariff Item 52. The Court ruled that there is no estoppel against a statute, allowing for the revision of classification despite prior approval under a different item.
