Export obligation extension bars premature customs duty and penalty enforcement until the extended period expires.

Where the competent authority extends the export obligation period, customs duty demand and penal consequences for alleged non-fulfilment of that obligation cannot be enforced before expiry of the extended term. The extension keeps the compliance period open, and liability cannot be fastened prematurely while the assessee remains within that period. The clause preserving action under other laws was treated as preserving proceedings for violations other than the very obligation for which extension had been granted, avoiding inconsistent action by different authorities. On that reasoning, premature enforcement was held impermissible and the assessee succeeded.

Issues: Whether customs duty demand and penal consequences could be enforced before expiry of the extended LOP period when the Development Commissioner had granted extension for fulfilment of export obligation and achievement of positive NFE.

Analysis: The extension granted by the Development Commissioner kept the export obligation period open for compliance during the extended term. The reasoning adopted was that, so long as the extended period had not expired, neither the Development Commissioner nor the customs authorities could treat the unit as having failed finally to fulfil its obligation for the first block period and fasten penal liability prematurely. The clause preserving action under other laws was read as preserving action for violations other than the non-fulfilment of export obligation for which extension had been granted. This avoided an anomalous situation where one authority grants time for compliance while another enforces liability before that time expires.

Conclusion: The demand was not sustainable before expiry of the extended period and the appeal was allowed in favour of the assessee.

Final Conclusion: Premature enforcement of customs duty liability was held impermissible where the competent authority had extended the export obligation period, and the assessee's appeal succeeded.

Ratio Decidendi: Where the competent authority grants extension of the export obligation period, penal or fiscal liability for non-fulfilment of that obligation cannot be fastened before expiry of the extended period.
