Issues Involved:
1. Calculation of duty payable under the Pan Masala Packing Machines (Capacity Determination and Collection of Duty) Rules, 2008.
2. Compliance with Tribunal's remand orders regarding duty calculation.
3. Timeliness and validity of the refund claim.
4. Application of the principle of unjust enrichment.

Issue-Wise Detailed Analysis:

1. Calculation of Duty Payable:
The appellant, engaged in manufacturing Gutkha, Pan Masala, and Scented Zarda, was required to calculate duty under Rule 7 and 8 of the Pan Masala Packing Machines (Capacity Determination and Collection of Duty) Rules, 2008. The Department alleged short payment of duty amounting to Rs. 59,45,966/- and issued a Show Cause Notice (SCN) on 26.12.2012. The initial adjudication confirmed the proposed demand, but upon appeal, the Tribunal remanded the matter for recalculating the duty based on the actual working period of the machines. The Department was directed to refund any excess duty paid within four months.

2. Compliance with Tribunal's Remand Orders:
Despite the Tribunal's clear directions in its orders dated 11.10.2017 and 18.02.2020, the Department failed to accurately compute the duty for the period when the second machine was not operational. The Tribunal reiterated that the appellant was not liable to pay duty for the period when the machine was sealed. The Department's subsequent orders continued to include periods of machine closure in the duty calculation, violating the Tribunal's remand instructions.

3. Timeliness and Validity of the Refund Claim:
The appellant filed a refund claim on 30.07.2018, which was initially returned as premature. A fresh SCN issued on 19.06.2019 proposed rejecting the refund claim as time-barred. The Original Adjudicating Authority confirmed this rejection, which was upheld by the Commissioner (Appeals). However, the Tribunal found that the refund claim was filed within one year of the relevant date, as per Section 11B(1) of the Central Excise Act, 1944. The relevant date was identified as the date of the Tribunal's orders (11.10.2017 and 03.11.2017), making the refund claim timely and valid.

4. Application of the Principle of Unjust Enrichment:
The Department's argument that the refund claim was hit by the principle of 'unjust enrichment' was dismissed by the Tribunal. It was noted that this ground was not raised in the impugned SCN, making the findings on unjust enrichment outside the scope of the SCN and liable to be set aside.

Conclusion:
The Tribunal set aside the orders under challenge, directing the Department to recalculate the duty based on the actual working days of the machines and to refund the excess amount paid by the appellant. The Department was instructed to comply with the Tribunal's directions within fifteen days, ensuring the appellant receives the consequential benefits. The appeal was allowed, and the Tribunal emphasized the need for judicial discipline and adherence to higher forum orders to prevent litigation and maintain order.
