UNION OF INDIA & ORS, vs SECURITY AND FINANCE (P) LTD.

The Supreme Court held that under Sections 3(2) and 4 of the Import and Export (Control) Act, 1947, and Section 167 of the Sea Customs Act, the Import Control Authority has the primary power to determine the classification of imported goods. The Court clarified that the imposition of import duty under Section 20 is a tax obligation, not a penalty, and does not preclude the authorities from levying differential duty under Section 183. The Court upheld the validity of the customs order, emphasizing that the dual nature of the order does not negate the authority's power to impose duty under Section 20, thus allowing the appeal by the Union of India.
