Court declares customs duty on imported coal unlawful, grants refund with interest. Limitation Act not applicable.

The court declared the levy and collection of additional duty of customs on imported coal as unlawful. The petitioners were granted a refund of the duty paid within three years preceding the filing of the petition, with 9% interest per annum, provided the duty burden was not passed on. The court dismissed the argument for a longer refund period based on the Limitation Act, emphasizing the need to examine unjust enrichment before granting refunds. The petition was partially allowed, directing authorities to assess unjust enrichment based on evidence presented by the petitioners.

Issues Involved:
1. Legality of the levy and collection of cess on the import of coking and non-coking coal.
2. Entitlement to a refund of the cess paid.
3. Applicability of the Limitation Act for the refund claim.
4. Examination of unjust enrichment before granting the refund.

Detailed Analysis:

1. Legality of the Levy and Collection of Cess:
The petitioners argued that the levy and collection of cess on the import of coking and non-coking coal by the respondents were unauthorized, illegal, and unconstitutional. They contended that under Section 6 of the Coal Mines (Conservation and Development) Act, 1974, the authorities had the power to collect only additional duty over and above excise duty on excisable goods, not on imported goods. The Supreme Court's decision in Commissioner of Central Excise & Customs, Bhubaneswar-I v. Tata Iron & Steel Co. Ltd. held that in the absence of a notification under Section 7 of the Coal Mines Act, no additional duty could be levied on imported coal. The court concurred, stating that the collection of additional duty as customs duty was wholly unauthorized and without authority of law.

2. Entitlement to a Refund of the Cess Paid:
The petitioners sought a refund of Rs. 67.17 lakhs paid towards the cess from January 1997 to December 2005. The court held that the collection of the duty was illegal and unauthorized, thus entitling the petitioners to a refund. However, the refund would be limited to the amount paid within three years immediately preceding the date of filing the petition (18-8-2006). The court directed that the refund be granted with simple interest at 9% per annum from the date of payment till the actual refund, subject to the condition that the burden of such duty was not passed on to the consumer or any other person.

3. Applicability of the Limitation Act for the Refund Claim:
The petitioners argued that the refund claim could be made within three years from the detection of the mistake, relying on Section 17(1) of the Limitation Act, 1963. The court rejected this contention, citing the Constitution Bench judgment in State of Madhya Pradesh & Anr. v. Bhailal Bhai & Ors., which held that the maximum period fixed by the Legislature for a suit in a civil court could be a reasonable standard for delay in seeking remedy under Article 226. The court also referred to the decision in Mafatlal Industries & Ors. v. Union of India & Ors., which stated that a refund claim on the ground of unconstitutionality must be made within the period of limitation prescribed under the Limitation Act.

4. Examination of Unjust Enrichment Before Granting the Refund:
The court emphasized that the principles of unjust enrichment must be examined before granting any refund. It referred to the decision in Mafatlal Industries & Ors. v. Union of India & Ors., which held that a refund claim could succeed only if the claimant established that the burden of duty had not been passed on to another person. The court directed that the issue of unjust enrichment be examined by the authorities based on the material produced by the petitioners.

Conclusion:
The court allowed the petition in part, declaring the collection of additional duty of customs as unlawful. The petitioners were entitled to a refund of the duty paid within three years preceding the filing of the petition, with interest, subject to the condition that the burden of such duty was not passed on to the consumer or any other person. The petition was disposed of with these directions, and the rule was made absolute to the aforesaid extent.
