Sea Customs Act procedure and revenue jurisdiction limits shaped the challenge to customs assessment and detention.

The Sea Customs Act scheme was treated as creating a special machinery under Sections 30, 31 and 32 for ad valorem and tariff value goods, and if Section 32 applied the Customs Authorities were bound to follow that procedure; a 50 per cent increase in declared value and a penal assessment were said to be unauthorised under the Act. The matter was also treated as falling within the constitutional bar on original jurisdiction in revenue disputes, and the applicant's failure to exhaust the statutory appellate remedies under the Act meant the High Court would not intervene.

Issues: (i) Whether the Customs Authorities were bound to proceed under Section 32 of the Sea Customs Act and whether the impugned assessment and detention were unauthorised; (ii) Whether the High Court could entertain the application in view of the bar on jurisdiction in matters concerning revenue and the applicant's failure to exhaust statutory remedies.

Issue (i): Whether the Customs Authorities were bound to proceed under Section 32 of the Sea Customs Act and whether the impugned assessment and detention were unauthorised.

Analysis: The scheme of the Sea Customs Act was treated as distinguishing between classes of goods, particularly ad valorem goods and tariff value goods, with Sections 30, 31 and 32 operating as the special machinery where Section 32 applied. The assessment adopted by the Customs Authorities, which increased the declared value by 50 per cent and treated the matter as a penal assessment, was held not to be warranted by the Act. If Section 32 applied, the Customs Authorities were bound to follow that procedure and could not treat the provision as optional.

Conclusion: The Customs Authorities could not justify the impugned action as a lawful assessment under the Act on the footing that Section 32 was merely optional.

Issue (ii): Whether the High Court could entertain the application in view of the bar on jurisdiction in matters concerning revenue and the applicant's failure to exhaust statutory remedies.

Analysis: The relief sought was held to concern revenue within the meaning of the constitutional bar on original jurisdiction. The Court further held that the applicant had not exhausted the appellate remedies provided by the Sea Customs Act before seeking mandamus. On that ground, interference by the Court was not permissible.

Conclusion: The application was not maintainable in the High Court.

Final Conclusion: The application failed because the dispute concerned revenue and the available statutory remedies had not been exhausted, so no writ-like relief could be granted against the Customs Authorities.
