DocketX / Glossary / writ of prohibition
A writ of prohibition is a court order that tells a lower court or government agency to stop doing something it has no legal authority to do.
It is a formal request to a higher court to halt proceedings in a lower court or tribunal that is acting outside its jurisdiction or exceeding its legal power. This writ typically arises when a party believes the lower court is about to make a ruling it has no right to make, and it is filed before that ruling is finalized.
If you are in a case and the court appears to be overstepping its authority, a writ of prohibition can stop the proceedings immediately, saving you time and expense. It matters because it prevents an invalid ruling from being issued, rather than forcing you to appeal after the fact.
People often confuse a writ of prohibition with a restraining order or an appeal. Unlike an appeal, which challenges a decision already made, a writ of prohibition stops the court from acting in the first place.
