If a person who is arrested, is NOT produced before the Magistrate within 24 hours from the time of arrest, he will be entitled to be released on the writ of ________.

The correct answer is Habeas Corpus.

Let's understand this step by step, breaking down the legal reasoning behind this answer.

Step 1: Understanding the Constitutional Right
In India, Article 22 of the Constitution guarantees certain fundamental rights to an arrested person. One of the most critical protections is that every person who is arrested must be produced before the nearest Magistrate within 24 hours of arrest (excluding the time necessary for the journey). If this right is violated, the detention becomes illegal and unlawful.

Step 2: What Happens When the 24-Hour Rule is Violated?
When an arrested person is not produced before a Magistrate within 24 hours, the continued detention of that person becomes unconstitutional and amounts to illegal custody. The person (or someone on their behalf) then has the right to challenge this unlawful detention in court.

Step 3: The Remedy — Writ of Habeas Corpus
The appropriate legal remedy in such a situation is the Writ of Habeas Corpus. The literal Latin meaning of "Habeas Corpus" is "You shall have the body." This writ is a court order directed at the authority detaining a person, commanding them to physically produce the detained person before the court and justify the legality of the detention.

Step 4: Why Not the Other Options?

- Prohibition: This writ is issued by a higher court to a lower court or tribunal to stop it from exceeding its jurisdiction. It has nothing to do with illegal detention.

- Quo-Warranto: This writ challenges a person's right or authority to hold a public office. It is unrelated to arrests or detention.

- Mandamus: This writ commands a public authority or lower court to perform a duty that it has failed to perform. While it could theoretically compel an action, it is not the specific remedy for illegal detention.

Step 5: Conclusion
Since the detained person's liberty is at stake due to an unlawful arrest or detention beyond 24 hours without being produced before a Magistrate, the Writ of Habeas Corpus is the most direct, specific, and powerful remedy available. It safeguards personal liberty, which is one of the most fundamental rights of an individual. The court, upon receiving such a petition, can order the immediate release of the person if the detention is found to be illegal.
