Case Note & Summary
The Supreme Court of India allowed the appeals filed by the State of Jharkhand against the judgment of the Jharkhand High Court, which had held that oxygen gas used in steel manufacturing by Tata Steel qualifies as 'raw material' under Section 13(1)(b) of the Bihar Finance Act, 1981, entitling the seller Linde India Limited to a concessional sales tax rate of 2% instead of 3%. The dispute arose from the sale of pure oxygen by Linde India Limited (formerly India Oxygen Limited) to Tata Steel for use in the Basic Oxygen Steelmaking (BOS) process. The State Government had issued notifications under Section 13(1)(b) providing a concessional rate of 2% for raw material inputs, while other goods were taxed at 3%. The assessing authority, after an inspection by a six-member expert committee, concluded that oxygen acts as a refining agent to reduce carbon content and is not a direct raw material for steel production, thus levying tax at 3%. This assessment was upheld by the appellate and revisional authorities. The High Court, in writ petitions, quashed these orders, holding that oxygen is a raw material because it chemically reacts to convert pig iron into steel. The Supreme Court reversed the High Court's decision, emphasizing that the concurrent findings of fact by the three authorities, based on expert opinion, should not have been interfered with under Article 226 unless perverse. On merits, the Court held that oxygen used as a refining agent does not constitute 'raw material' as it is not a direct input but a processing aid, relying on the precedent in Deputy Commissioner of Sales Tax v. Thomas Stephen & Co. Ltd. The Court restored the assessment order and demand notice, dismissing the respondents' claim for concessional rate.
Headnote
A) Sales Tax - Raw Material - Concessional Rate - Section 13(1)(b) Bihar Finance Act, 1981 - The issue was whether oxygen gas supplied to Tata Steel for steel manufacturing qualifies as 'raw material' for concessional tax rate of 2%. The Supreme Court held that oxygen used as a refining agent to reduce carbon content is not a raw material but a processing aid, and thus not eligible for concessional rate. The Court restored the assessment order levying 3% tax. (Paras 1-10) B) Constitutional Law - Judicial Review - Article 226 - Interference with Concurrent Findings - The High Court erred in interfering with concurrent findings of fact by three authorities (Assessing Officer, Appellate Authority, Revisional Authority) based on expert committee report. The Supreme Court held that such findings, unless perverse or based on no evidence, should not be disturbed in writ jurisdiction. (Paras 3-6) C) Sales Tax - Raw Material - Definition - Refining Agent - Goods used as refining agent or for ancillary purposes like fuel cannot be treated as raw material. The Court relied on Deputy Commissioner of Sales Tax v. Thomas Stephen & Co. Ltd. (1988) 2 SCC 264 to distinguish between raw material and processing aids. (Paras 7-8)
Issue of Consideration
Whether oxygen gas used in the Basic Oxygen Steelmaking (BOS) process for manufacturing steel can be considered 'raw material' under Section 13(1)(b) of the Bihar Finance Act, 1981, entitling the seller to concessional rate of tax at 2% instead of 3%.
Final Decision
The Supreme Court allowed the appeals, set aside the High Court's judgment, and restored the assessment order dated 1.10.2011 and demand notice dated 10.10.2011, holding that oxygen is not 'raw material' and tax at 3% is applicable.
Law Points
- Interpretation of 'raw material' under sales tax law
- Scope of judicial review under Article 226 against concurrent findings
- Distinction between raw material and refining agent in manufacturing process
