 Hay-based corpus, it is one of the five RITs issued by Supreme Court under Article 32 and the High Court under Article 226. Supreme Court can issue RITs only in violation of Fundamental Rates, whereas High Court can issue RITs in violation of both Fundamental Rates and Legal Rates. So, the RIT jurisdiction of High Court is wider than that of Supreme Court. Now, if you take Hay-based corpus, Hay-based corpus literally means to have the body off. It is issued by the courts to produce a person before the court who has been detained in prison or in private custody. It means Hay-based corpus can be issued against both public authorities and private individuals. Hay-based corpus is issued in order to know on what ground the person has been detained. If the court finds the detention is unlawful, then the court directs concerned authority to release the detained person. Hay-based corpus RIT can be filed by the detained person himself or by the relatives or friends of the detained person or by any other person. So, the principle of local standee is not necessary to issue Hay-based corpus.
