Part III of the Indian Constitution deals with Fundamental Rights. Among these, the right to freedom includes protection against arbitrary arrest and detention. - Article 15 prohibits discrimination on grounds of religion, race, caste, sex, or place of birth. - Article 17 abolishes Untouchability. - Article 21 guarantees protection of life and personal liberty. It states that no person shall be deprived of his life or personal liberty except according to procedure established by law. This is a broad right. - Article 22 specifically provides protection against arbitrary arrest and detention. It grants several rights to a person who is arrested: 1. Right to be informed of the grounds of arrest. 2. Right to consult and be defended by a legal practitioner of one's choice. 3. Right to be produced before the nearest Magistrate within 24 hours of arrest, excluding the time taken for the journey. 4. Right not to be detained in custody beyond 24 hours without the authority of a Magistrate. These safeguards aim to prevent illegal detention and provide legal assistance to the arrested person.
