CTO Anti Evasion Circle III Rajasthan Jaipur v. M/S Prasoon Enterprises Jaipur
Background
The respondent dealer traded in spare parts for mining machinery, including wire ropes used in mobile cranes, and was paying VAT on these ropes at 4% under a specific entry for mobile cranes and their parts. The Commercial Tax Department (CTO) conducted a survey and took the view that wire ropes did not qualify as "parts" of mobile cranes, so they should instead be taxed at the higher residuary rate of 12.5%. The dealer won at every stage below, before the Appellate Authority, the Rajasthan Tax Board, and the Rajasthan High Court, prompting the State to appeal to the Supreme Court.
Decision Breakdown
The Supreme Court applied the established legal test for what counts as a "part" of a machine: a thing is a part of another if the other cannot function, or cannot function effectively, without it. Based on technical literature and Bureau of Indian Standards specifications placed on record, the Court found that mobile cranes cannot operate without wire ropes, so the ropes qualify as "parts" of mobile cranes under the relevant VAT Schedule entry and are taxable at 4%, not the higher residuary rate. The appeal by the tax department was dismissed, and three connected appeals raising the same question were dismissed on the same reasoning.
Lesson Learnt
For tax classification purposes, a component is treated as a "part" of machinery if the machinery cannot function properly without it: a practical, function-based test that can determine which tax rate applies to spare parts and accessories.
