Reasonable belief for customs seizure must rest on reliable scientific material; unsupported botanical reports cannot sustain confiscation.

Customs seizure and confiscation proceedings require a bona fide reasonable belief, founded on reliable material, that the export consignment contains prohibited goods. Here, conflicting botanical opinions were assessed, and the later scientific report using macroscopic, microscopic, and chromatographic examination was preferred. On that evidence, the consignment was found to contain Vinca rosea roots and stems and stems of Rauwolfia canescens, not Rauwolfia serpentina. As the alleged prohibited substance was not established, the seizure, show-cause notice, adjudication, and penalty proceedings were quashed and the goods ordered to be released.

Issues: Whether the customs authorities had a reasonable belief that the export consignment contained prohibited goods so as to justify seizure, issuance of notice, and initiation of confiscation and penalty proceedings.

Analysis: The consignment was subjected to conflicting botanical opinions. The later report from the Central Research Institute for Siddha was preferred because it disclosed the scientific basis of identification through macroscopic, microscopic, and chromatographic examination, whereas the earlier departmental opinions were unsupported by disclosed scientific methodology and were internally inconsistent. On that material, the consignment was found to consist of Vinca rosea roots and stems and stems of Rauwolfia canescens, not Rauwolfia serpentina. Since the material actually found did not fall within the prohibited category, the premise for action under the Customs Act and the export control provisions failed. In those circumstances, the officers could not reasonably have formed the belief required at the time of seizure or notice, and the proceedings lacked the necessary jurisdictional basis.

Conclusion: The seizure, show-cause notice, and consequential adjudication proceedings were unsustainable and were quashed; the goods were ordered to be released.

Final Conclusion: The writ petition succeeded because the alleged banned substance was not established in the export consignment, and the customs action was held to be without jurisdiction.

Ratio Decidendi: Customs confiscation and penalty proceedings based on prohibited export goods require a bona fide reasonable belief founded on reliable material; where the seized consignment is shown, on preferable scientific evidence, not to contain the alleged prohibited item, the action cannot be sustained.
