The ground norm of our criminal justice system is that an accused is innocent until proven guilty. It has been held by the apex court, that, presumption of innocence preserves confidence in the enduring integrity and security of a legal system. Article 21 of the Constitution is explicit. Entitled ‘Protection of life and personal liberty’, it states: “No person shall be deprived of his life or personal liberty except according to procedure established by law.” This is also called the due process clause. It is supplemented by Article 22 that lays down the safeguards when a person is arrested or preventively detained.
