DocketX / Glossary / writ of mandamus
A writ of mandamus is a court order that commands a government official or lower court to perform a specific duty they are legally required to do.
It is an extraordinary remedy used when a party has no other adequate legal means to compel a public official or judge to act. In a case, it typically appears as a petition asking a higher court to order a lower court to take a particular action, such as ruling on a pending motion or exercising jurisdiction.
If you are in a case and a judge or official is refusing or unreasonably delaying a required act, a writ of mandamus can force them to act. However, courts grant it only sparingly, usually when you have no other way to get relief and the duty is clear.
A common mistake is thinking mandamus can force a judge to decide a case a certain way; it only compels them to perform a ministerial duty, not to exercise discretion in your favor. It is not an appeal or a substitute for an ordinary legal remedy.
