M/S. NATIONAL ENGINEERING INDUSTRIES vs COMMNR. OF CENTRAL EXCISE, JAIPUR — C.A. No. 4944/2000

Case Summary: National Engineering Industries v. Commissioner of Central Excise, Jaipur Outcome: The Supreme Court dismissed National Engineering Industries' civil appeal on September 14, 2005. The court upheld the CEGAT's denial of excise duty refund on unjust enrichment grounds, finding no infirmity in the lower tribunal's judgment. Key Issue: The appellant sought refund of excise duty for 1976-1979 under Notification No. 198/76-CE. Although CEGAT initially decided the benefit calculation dispute in appellant's favor, the refund was withheld because the company had already recovered the amounts from customers. By the time refund claims were processed in 1993, Section 11-B had been amended to incorporate the unjust enrichment doctrine, which applied to bar the refund. Reasoning: The court held that the law applicable at the time the refund claim was actually considered (1993) must govern, and under the amended Section 11-B, no refund could be granted where amounts were already recovered from customers.
