Here is a judgment on Custodial Deaths.
The Supreme Court has consistently reiterated the importance of Article 21 Of our cherished Constitution.
“Fundamental rights occupy a place of pride in the India Constitution. Article 21 provides “no person shall be deprived of his life or personal liberty expect according to procedure established by law”. Personal liberty, thus, is a sacred and cherished right under the Constitution. The expression “life of personal liberty” has been held to include the right to live with human dignity and thus it would also include within itself a guarantee against torture and assault by the State or its functionaries. ”
Each time a person is arrested under 498A without any investigation, the arresting officer is breaking the law of the land.
