A writ is a formal legal order issued by a court or a legal authority. It commands an individual or entity to perform a specific act or to refrain from doing something. Writs are often used to ensure compliance with the law and can address various legal matters, such as the protection of rights or the enforcement of judgments. There are different types of writs, including habeas corpus, which protects against unlawful detention, and mandamus, which compels a government official to perform a duty. Writs play a crucial role in the judicial system, helping to uphold justice and maintain order.
