Custodial violence directly violates the right to life and personal liberty guaranteed under Article 21 of the Indian Constitution. When law enforcement agencies use torture or brutality against detainees, it undermines the dignity and safety that Article 21 protects. Such violence leads to physical and mental harm, sometimes causing death, which is a grave infringement of this fundamental right. It also erodes public trust in the justice system and violates the principle of humane treatment. Therefore, custodial violence is a serious abuse that compromises the constitutional guarantee of life and liberty.
