🔡 Root

Medieval Latin habeas corpus = you shall have the body; habēre = to have; corpus = body

📜 Etymology

From Medieval Latin habeas corpus ad subjiciendum, meaning "you shall have the body to be subjected to examination"; habeas from Latin habēre ("to have") and corpus ("body").

🧠 Memory Hook

"Habeas" sounds like "have us" + "corpus" = "body": the court orders the jailer to "have us the body" — produce the prisoner in person to prove the detention is lawful.

🎯 How This Word Works in UPSC Writing

The writ requiring that a detained person be produced before a court so the legality of the detention can be tested. It is the oldest and most fundamental of the writs because it goes to the fact of detention itself rather than to any procedural defect, and it places the burden on the state to justify depriving a person of liberty. The Indian case that defines it is ADM Jabalpur v Shivkant Shukla in 1976, where the Supreme Court held by four to one that once the President had suspended the right to move courts for enforcement of Article 21, a detenu had no standing to seek the writ at all, which left no remedy even against unlawful detention. Justice H.R. Khanna dissented alone, holding that the right to life and liberty does not owe its existence to the Constitution, and he was passed over for the Chief Justiceship. The nine-judge bench in Puttaswamy expressly overruled the decision in 2017.

⚖️ Don’t Confuse It With

Habeas corpus tests the legality of a detention and may be sought against the state or a private person. Mandamus commands a public authority to perform its duty, certiorari quashes the order of a lower body, prohibition forbids it from exceeding its jurisdiction, and quo warranto questions a person's title to a public office, the five together being the writs available under Articles 32 and 226. Preventive detention is detention without trial to forestall an apprehended act, and is what habeas corpus is most often used to challenge.
