I was placed under preventive detention in Lucknow; what rights do I have?

Preventive detention is permitted under Article 22(4) only on grounds specified in law and for a limited period, with a right to be informed of the grounds and to make a representation to an advisory board. The detention order must be reviewed by the advisory board within the prescribed period, and the detainee can be represented by a lawyer of choice in some statutes. File a habeas corpus petition under Article 226 in the Allahabad High Court challenging the detention and seeking release if the safeguards were not observed. The court will examine the grounds, the advisory board report and the compliance with the procedural safeguards. Uttar Pradesh Rent Control Act 1972 on preventive detention must specify the grounds and the procedure, and any vagueness in the grounds vitiates the detention. Preserve the detention order, the grounds communicated and any representation filed in Lucknow. The court can quash the detention and award compensation for the illegal custody.
