Ganga Ramchand Bharvani v. Under Secretary to the Government of Maharashtra and Ors. (1980) 4 SCC 624

The mere fact that the grounds of detention served on the detenu are elaborate, does not absolve the detaining authority from its constitutional responsibility to supply all the basic facts and materials relied upon in the grounds to the detenu. In the instant case, the grounds contain only the substance of the statements, while the detenu had asked for copies of the full text of those statements.
