Temporary Restraining Order
Akin to a preliminary injunction, it is a judge's short-term order forbidding certain actions until a full hearing can be conducted. Often referred to as a TRO.

A court order, sometimes called a "TRO," that says a person must not do certain things that are likely to cause harm that can't be fixed. Unlike an injunction , it can be granted immediately, without notice to the opposing party and without a hearing. It is intended to last only until a hearing can be held. TROs are often used in domestic violence cases to protect a person from violence or the threat of violence.
