Habeas corpus is a legal order that requires a person who is holding someone in custody to bring the detainee before a court or judge. This writ is typically issued to protect individuals from unlawful detention or imprisonment. Therefore, it is issued in situations where there is a faulty or improper police detention, ensuring that individuals are not held without proper legal justification or due process.
