Case Note & Summary
This case involved an appeal by the Commissioner of Central Excise, Mumbai against the order of the Customs Excise & Gold (Control) Appellate Tribunal, which had allowed the appeal of M/s National Organic Chemical Industries Limited regarding the exemption of excise duty on ethylene and propylene. The respondent manufactured these substances by cracking raw naphtha, which also produced methane and ethane as by-products. The appellant contended that the exemption under notification no.217/86 CE did not apply because ethylene and propylene were used in the manufacture of goods falling under chapter 27, which was not specified in the exemption notification. The respondent argued that the emergence of by-products was inevitable and did not affect their entitlement to the exemption. The Tribunal ruled in favor of the respondent, stating that the simultaneous production of ethylene and propylene alongside by-products did not disqualify them from the exemption. The Supreme Court upheld the Tribunal's decision, emphasizing that the exemption notification should be interpreted liberally and that the emergence of by-products does not negate the benefit of the exemption. The appeal was dismissed, and the parties were directed to bear their own costs.
