Preventive detention disclosure rules require clear notice of additional material's purpose to preserve an effective representation.

Additional material may be supplied in support of preventive detention grounds, but Article 22(5) requires that the detenu be informed in a clear and effective manner of its purpose and intended use. Where documents are furnished casually, without a covering explanation showing who sent them, why they were supplied, and that they would be considered by the Advisory Board and the Government, the constitutional safeguard of an effective representation is impaired. The Court held that such disclosure can violate Article 22(5), and the detention order was quashed because the detenu's right to make a timely and meaningful representation was not properly preserved.

Issues: Whether the supply of additional documents to the detenu, without informing him of their purpose or intended use in the confirmation process, violated Article 22(5) of the Constitution of India and invalidated the detention order.

Analysis: The documents furnished to the detenu were not treated as additional grounds of detention, but as additional material supporting the existing grounds. However, the manner in which they were supplied was found to be casual and confusing, as no covering letter explained who furnished them, why they were sent, or that they would be placed before the Advisory Board and the Government for confirmation. In preventive detention matters, strict compliance with the constitutional safeguard of affording the earliest opportunity to make an effective representation is required. Where the detenu is left unaware of the purpose and consequence of the supplied material, the safeguard under Article 22(5) is impaired.

Conclusion: The supply of the documents in the manner adopted infringed the detenu's right under Article 22(5), and the detention order was rightly quashed.

Final Conclusion: The detention could not be sustained because the constitutional right to an effective and timely representation was not properly preserved.

Ratio Decidendi: Additional material in support of detention grounds may be furnished, but it must be supplied in a manner that preserves the detenu's effective opportunity to represent; casual disclosure that obscures its purpose can amount to infringement of Article 22(5).
