Article 21 of the Constitution of India proscribes deprivation, of the life and liberty of every Indian citizen, save and except by "procedure established by law". The law, in this country, permits deprivation of the liberty of the citizen, by her, or his, incarceration, during trial, as well as after its conclusion, but for different reasons, and to achieve different purposes. Incarceration, after trial and consequent on the accused being found guilty, is punitive in nature. Punishment, by plain logic, has necessarily to follow a determination of guilt, accompanying conviction, and can never be anterior thereto. Incarceration during trial, therefore, can never be punitive in nature and is never intended to operate as a punishment, as was rightly held in H. B. Chaturvedi vs C.B.I., 171 (2010) DLT 223 .
