What is the court's permanent order that forbids an action called?

The correct choice is the term that refers to a judicial order requiring a party to do or refrain from doing specific acts. An injunction is a powerful legal tool used in various types of cases. It is typically issued by a court to prevent harm or preserve the status quo until a final decision is reached. Injunctions can be temporary or permanent, but a permanent injunction specifically enforces a court's decision that bans certain actions indefinitely.

In contrast, a mandate generally refers to an authoritative command or instruction, and while it can relate to legal frameworks, it doesn't specifically describe a court order forbidding an action. A writ is a formal written order issued by a body with administrative or judicial jurisdiction, but again, it does not specifically refer to the prohibition of actions in the way an injunction does. A subpoena is a document that orders an individual to appear in court or produce evidence, which is unrelated to forbidding actions. Therefore, the term that accurately reflects a court's permanent order that prohibits certain actions is an injunction.
