Held

The Court held that the provisions of Section 11B of the Central Excise Act, 1944, are not applicable to cases where tax or cess was paid under a mistake of law. The reasoning was that the EC and SHEC paid by the respondent were not duties of excise and were collected/accepted by the appellant without the authority of law, violating Article 265 of the Constitution. Therefore, the retention of such amounts was impermissible. The Court agreed with the decisions of various High Courts that when a person is not liable to pay tax, the department cannot retain the amount mistakenly paid, and the bar of limitation under Section 11B cannot affect the refund of such amounts. The Court found no merit in the argument regarding unjust enrichment, as the primary issue was the illegality of the collection. The Court dismissed the appeals, holding that the appellant must refund the EC and SHEC mistakenly paid by the respondents.

Facts

The Commissioner of CGST and Central Excise, Dibrugarh (appellant) has appealed against an order of the Customs, Excise and Service Tax Appellate Tribunal (CESTAT) that allowed M/s Oil India Limited (respondent) to claim a refund of Education Cess (EC) and Secondary and Higher Education Cess (SHEC). The respondent had mistakenly paid these cesses on Oil Industry Development (OID) Cess, which was not legally leviable. The respondent sought a refund under Section 11B of the Central Excise Act, 1944. The Adjudicating Authority and the Commissioner (Appeals) had rejected the refund claim in part, citing the one-year limitation period under Section 11B. The CESTAT, however, held that Section 11B was not applicable to payments made under a mistake of law.

Key Issues

1. Whether the provisions of Section 11B of the Central Excise Act, 1944, prescribing a statutory time limit for claiming refund, are applicable to cases where tax or cess was paid under a mistake of law, and if such claims are time-barred even when payment was made erroneously or without legal authority? 2. Whether the Appellate Tribunal erred in law by ignoring the statutory presumption of unjust enrichment embedded in Section 11B of the Central Excise Act, 1944, and granting refund based solely on a CA certificate without substantive evidence that the incidence of EC and SHEC was not passed on to consumers? The appellant argued that Section 11B of the Central Excise Act, 1944, which prescribes a limitation period for refund claims, is applicable. They contended that the respondent failed to produce tangible evidence to prove that the incidence of EC and SHEC was not passed on to consumers, thus violating the principle of unjust enrichment. The respondent argued that since the EC and SHEC were paid under a mistake of law and were not leviable, the bar of limitation under Section 11B should not apply. They relied on various High Court decisions, including Gujarat, Delhi, and Karnataka High Courts, which held that Section 11B is not applicable to refunds of amounts paid erroneously or without legal authority.
