What is used to stop an individual from performing a certain act by court order?

The correct choice is "Enjoin." When a court "enjoins" an individual, it means that the court is issuing an order to prohibit or restrain that person from performing a specific act. This legal term derives from the broader concept of injunctions, which are common in legal proceedings aimed at preventing harm or preserving the status quo.

Choosing "Enjoin" reflects a direct application of a judicial command that is often explicit in legal documents. It is about the authoritative direction issued by the court to ensure compliance. In situations where an individual is compelled or restrained from taking certain actions, the term emphasizes the power of the court to enforce obedience.

In contrast, while "restraining order" and "injunction" also serve similar purposes, those terms are often used to describe the types of orders issued. A "restraining order" usually refers to a specific type of injunction that prevents an individual from engaging in certain actions, particularly in cases involving harassment or domestic violence. An "injunction" is a broader term that encompasses any directive prohibiting an action. "Writ," on the other hand, refers to various formal orders issued by a body with administrative or judicial jurisdiction, and is not specifically focused on stopping an individual's actions.
