3. Implementation of High Court orders.

Detailed Analysis:

1. Refund Claim of Customs Duty:
The appellant filed a refund claim on 12.01.1987 for customs duty amounting to Rs. 1,50,99,362.95, paid under protest during the period 29.05.1996 to 22.09.1996. The claim was based on the exemption under Notification No.133/85, which allowed a 'nil' rate of Basic Customs Duty. The Customs department disputed this, denying the benefit due to the amended Notification No.306/86, which excluded captive power plants from the exemption. The appellant paid the duty under protest and sought a refund, which was not sanctioned initially, leading to a series of legal proceedings.

2. Applicability of Notification No.133/85 and Notification No.306/86:
The appellant's claim for exemption under Notification No.133/85 was denied by the department based on Notification No.306/86, which excluded captive power plants from the exemption. The High Court quashed the part of Notification No.306/86 that denied benefits to captive power plants. Despite the High Court's order, the department continued to deny the refund, leading to further legal actions by the appellant.

3. Implementation of High Court Orders:
The High Court, in its order dated 02.03.1995, allowed the appellant's writ petitions and quashed the part of Notification No.306/86 affecting captive power plants. The department's subsequent writ appeals were dismissed by the High Court on 17.07.2000 and 13.10.2008, making the High Court's order final. Despite this, the department issued a show-cause notice demanding recovery of the sanctioned refund, which the appellant challenged successfully.

4. Doctrine of Unjust Enrichment:
The department argued that the doctrine of unjust enrichment, incorporated into the Customs Act from 20.09.1991, applied retrospectively. They cited several Supreme Court judgments to support this claim. However, the appellant contended that the High Court's order, which had attained finality, did not consider unjust enrichment, and thus the refund should be granted without this consideration.

5. Compliance with Supreme Court Judgments:
The department relied on the Supreme Court's decision in Union of India Vs Indian Charge Chrome, which upheld the validity of Notification No.306/86. However, the appellant argued that this decision was not applicable to their case, as the High Court's order had already attained finality, and no stay was granted against it. The Tribunal agreed with the appellant, stating that the High Court's order was binding and could not be circumvented by the department.

Conclusion:
The Tribunal concluded that the High Court's order dated 02.03.1995 had attained finality and was binding on the department. The adjudicating authority's order sanctioning the refund was in compliance with the High Court's order. The Tribunal rejected the department's appeal and allowed the appellant's appeal, directing the department to return the refunded amount to the appellant without further delay. The Tribunal emphasized the importance of judicial discipline and the binding nature of the High Court's orders on subordinate authorities.
