Case Note & Summary
The case involved M/s Patanjali Foods Limited, formerly known as M/s Ruchi Soya Industries Limited, appealing against a judgment of the Gujarat High Court regarding customs duty refunds. The appellant had imported crude degummed soybean oil and faced issues with the customs department over the payment of differential duty based on a notification that was not in the public domain at the time of import. The appellant challenged the notification and was granted interim relief by the High Court, which allowed the clearance of goods upon furnishing bank guarantees for the differential duty. After the High Court dismissed the writ petitions, the department encashed the bank guarantees, prompting the appellant to seek refunds. The High Court ruled that the doctrine of unjust enrichment applied, requiring the appellant to prove that the duty had not been passed on to customers. The Supreme Court, however, found that the encashment of bank guarantees did not constitute payment of duty and thus the unjust enrichment principle was not applicable. The Court directed the respondents to refund the amounts along with interest, emphasizing that the retention of funds was unlawful. The appeals were allowed, and the High Court's decision was set aside.
