Preventive detention must consider the exact contraband, all relied-upon documents, and material discrepancies to preserve representation rights.

Preventive detention orders were said to be vulnerable where the detaining authority did not address whether the seized substance was Ketamine or Ketamine Hydrochloride and did not consider the legal effect of the export notification on the substance actually identified. The orders were also found defective because a relied-upon shipping bill and complete weighment records were not supplied, impairing the detenus' effective right to make a representation. A further material discrepancy between the declared and actual number of bags in the container, left unexplained and unsupported by complete records, was treated as showing non-application of mind. The note states that such omissions vitiate detention.

Issues: (i) Whether the detention orders were vitiated for non-application of mind on the question whether the contraband was Ketamine or Ketamine Hydrochloride and on the applicability of the export notification. (ii) Whether non-supply of relied upon documents, including the shipping bill and weighment-related records, deprived the detenus of an effective opportunity to make representation. (iii) Whether the unexplained discrepancy in the number of bags found in the container and the related material defects showed non-application of mind and vitiated the detention.

Issue (i): Whether the detention orders were vitiated for non-application of mind on the question whether the contraband was Ketamine or Ketamine Hydrochloride and on the applicability of the export notification.

Analysis: The grounds of detention and the materials supplied reflected uncertainty between Ketamine and Ketamine Hydrochloride, while the chemical analysis indicated Ketamine Hydrochloride and the notification relied upon referred to Ketamine. As the respondents conceded that the two were distinct and the detaining authority did not address the legal effect of that distinction or the applicability of the notification to the substance actually identified, the subjective satisfaction was found to be based on an incomplete consideration of material facts and law.

Conclusion: The detention orders were vitiated on this ground.

Issue (ii): Whether non-supply of relied upon documents, including the shipping bill and weighment-related records, deprived the detenus of an effective opportunity to make representation.

Analysis: A vital shipping bill was not supplied, though it was relied upon in the grounds, and the detenus were also not furnished with complete and clear copies of the weighment records referred to in the detention orders. Since the right to make an effective representation requires supply of all relied upon documents, the omission caused prejudice and impaired the constitutional safeguard available to the detenus.

Conclusion: The detention orders were vitiated on this ground as well.

Issue (iii): Whether the unexplained discrepancy in the number of bags found in the container and the related material defects showed non-application of mind and vitiated the detention.

Analysis: The record disclosed a material mismatch between the declared number of bags and the bags actually found, while the authorities did not obtain clarification from the customs officials who had loaded, sealed, and supervised the container. The omission to examine this vital discrepancy and the absence of complete supporting statements demonstrated a failure to apply mind to a material circumstance bearing on the detention.

Conclusion: The detention orders were vitiated on this ground also.

Final Conclusion: The preventive detention orders could not survive judicial scrutiny and the detenus were entitled to immediate release unless required in any other case.

Ratio Decidendi: In preventive detention matters, failure to apply mind to the exact nature of the contraband and to all relied upon and material documents, especially where such omissions impair the detenus' right to make an effective representation, vitiates the detention order.
