A more thorough explanation:

Definition: Great Writ is another term for Habeas Corpus, which is a legal term that means "that you have the body." It is a writ used to bring a person before a court to ensure that their imprisonment or detention is not illegal. It can also be used to test the legality of an arrest or commitment, obtain review of the regularity of the extradition process, the right to or amount of bail, or the jurisdiction of a court that has imposed a criminal sentence.

Example: If someone is arrested and detained without a proper reason, they can file a petition for a writ of habeas corpus to challenge their detention and bring them before a court. For example, if someone is arrested for a crime they did not commit, they can use the writ of habeas corpus to prove their innocence and be released from detention.

Explanation: The example illustrates how the writ of habeas corpus can be used to challenge the legality of an arrest or detention. It ensures that a person's rights are protected and that they are not held in custody without a proper reason. The writ of habeas corpus is an important legal tool that helps to safeguard individual liberties and prevent abuses of power by the government.
