What is a requirement for a preliminary injunction to be issued against a party in a legal dispute?

A preliminary injunction is a legal remedy that can be issued by a court to maintain the status quo and prevent harm to one party while a legal dispute is being resolved. A critical requirement for a court to issue a preliminary injunction is that the opposing party must receive adequate notice. This ensures that the party against whom the injunction is sought has the opportunity to respond and present their case before any restrictions are placed upon them.

The requirement for adequate notice is rooted in principles of due process, which require that all parties be informed of legal actions that could affect their rights or interests. Without proper notice, issuing an injunction could lead to unfairness or prejudice against the party who was not informed.

The other options do not reflect necessary criteria for issuing a preliminary injunction. Filing in federal court, mutual agreement, or a request by a federal judge are not prerequisites for obtaining a preliminary injunction. The main focus is on ensuring that all parties involved have the opportunity to engage in the legal process fairly.
