Case Note & Summary
The dispute arose from the Union of India's appeal against Solar Pesticides Pvt. Ltd. regarding the refund of additional customs duty paid on imported copper scrap used in manufacturing copper oxychloride. The respondent sought exemption from the duty under a specific customs notification but had their refund application rejected by the Assistant Collector of Customs. Following this, the respondent filed a writ petition in the Bombay High Court, which ruled in their favor, stating that the exemption notification applied and that the unjust enrichment principle did not apply to captive consumption. The Union of India contended that the High Court's decision was flawed, particularly in light of the amendments to the Customs Act, which introduced a burden of proof on the claimant to demonstrate that the duty had not been passed on to others. The Supreme Court analyzed the relevant sections of the Customs Act, particularly Section 27, and concluded that the principle of unjust enrichment applies even in cases of captive consumption. The court emphasized that the burden of proof lies with the claimant to establish that the duty was not passed on. The court ultimately allowed the appeal, set aside the High Court's judgment, and dismissed the writ petition filed by Solar Pesticides Pvt. Ltd. The decision also directed the Tribunal to reconsider several related appeals regarding the unjust enrichment principle and its applicability to captive consumption cases.
