4. Need for sufficient documents to establish non-passing on of duty incidence.

6. Applicability of limitation in case of tax payment made under mistake.

Analysis:
1. The appellants filed a refund claim for service tax paid mistakenly under "Survey and Exploration of Minerals Services." The original authority deemed the activities taxable under section 65(105)(zzzy) of the Finance Act, 1994. The Commissioner (Appeals) rejected the refund claim as time-barred and due to unjust enrichment. The appellants appealed to the Tribunal.

2. The appellant argued that the service tax was paid based on incorrect advice. The refund claim rejection was based on unjust enrichment. The appellant requested a chance to prove non-collection of tax from customers with documentary evidence.

3. The main ground for refund claim rejection was the lack of documents to prove non-passing on of duty incidence. The Tribunal noted the necessity to consider the issue of unjust enrichment while adjudicating a refund application. The matter was remanded to the original authority for further review.

4. The appellants contended that the refund claim was not time-barred as the tax was paid mistakenly. Citing legal precedents, including a decision by the Bombay High Court, the Tribunal discussed the applicability of limitation in cases of tax payment made under a mistake of law.

5. The Tribunal referenced a decision by the Madras High Court to support the rejection of the claim as time-barred. However, regarding the issue of unjust enrichment, the Tribunal set aside the finding and remanded it for further consideration by the adjudicating authority.

6. After thorough analysis and discussion, the Tribunal allowed the appeal by way of remand, emphasizing the need to provide the appellant with an opportunity to establish that the duty incidence was not passed on. The judgment was dictated and pronounced in open court.
