Case Note & Summary
The case involved two appeals concerning the classification of oxygen gas for sales tax purposes under the Bihar Finance Act, 1981. The appellants, M/s BOC India Ltd. and M/s Tata Steel Ltd., contested a demand for differential sales tax rates on oxygen gas supplied for steel manufacturing. BOC had supplied oxygen to Tata Steel since 1993, and both parties had previously operated under a registration certificate that classified oxygen gas as taxable at 3%. However, BOC later attempted to charge a lower rate of 2% based on notifications regarding raw materials. The Deputy Commissioner of Commercial Taxes issued notices demanding the balance tax amount, leading BOC to file a writ petition challenging the legality of the demand. The High Court dismissed the petition, ruling that BOC lacked standing since the tax liability ultimately fell on Tata Steel. The Supreme Court, however, found that BOC had sufficient interest to challenge the demand and that the classification of oxygen gas as a raw material required factual determination by the Assessing Authority. The court set aside the High Court's judgment, allowing the appeals and directing the Assessing Authority to consider evidence regarding the classification of oxygen gas. The decision emphasized that all parties should have the opportunity to present their case regarding the nature of the goods and the applicable tax rate.
