Injunction: An order of the court prohibiting (or compelling) the performance of a specific act to prevent irreparable damage or injury.
State: when applied to different parts of the United States, may be construed to include the District of Columbia and the several territories, and the words "United States" may be construed to include the said district and territories. See Illinois Compiled Statutes 5 ILCS 70/1.14
Temporary restraining order: Prohibits a person from an action that is likely to cause irreparable harm. This differs from an injunction in that it may 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.
