The appeals were allowed, granting consequential relief. The court determined that coal samples were correctly tested according to IS 1350, using the GAD method for ash content determination. The respondents were estopped from contesting the sampling method, as they did not object during provisional assessment. Consequently, they were not entitled to exemption benefits.

Issues Involved:
1. Validity of the method used for drawing and testing coal samples.
2. Entitlement to the benefit of exemption notifications based on ash content.
3. Applicability of estoppel against the respondents for not objecting to the sampling method at the time of provisional assessment.

Issue-wise Summary:

1. Validity of the method used for drawing and testing coal samples:

The judgment discusses the procedural standards for drawing and testing coal samples as per IS 436 and IS 1350. The department did not follow IS 436 for drawing samples, and the respondents argued that non-representative samples render the test results unreliable. Despite this, the court noted that the respondents were present during sampling and did not object to the method at the time. The court held that the samples were tested in accordance with IS 1350, and the gross air-dried (GAD) method is universally recognized for testing ash content.

2. Entitlement to the benefit of exemption notifications based on ash content:

Notification 35/90 and Notification 23/91 exempt coking coal with ash content below 12% from certain duties. The imported coal was tested by CFRI and CRCL, both indicating ash content above 12%. The respondents contested the results, arguing the coal should be tested on an 'as received' basis rather than the GAD method. The court disagreed, stating that the GAD method was correctly used and binding on both parties. Consequently, the respondents were not entitled to the benefit of the exemption notifications.

3. Applicability of estoppel against the respondents for not objecting to the sampling method at the time of provisional assessment:

The court emphasized that the respondents, being aware of the sampling method used at Okha Port, did not object during the provisional assessment and accepted the samples without protest. The doctrine of estoppel was applied, preventing the respondents from later contesting the sampling method after benefiting from the provisional clearance. The court held that the respondents are estopped from claiming that samples should have been drawn as per IS 436.

Conclusion:

The appeals were allowed with consequential relief, if any, as the court found that the coal samples were tested correctly in accordance with IS 1350, and the GAD method was appropriate for determining ash content.
