Introduction to Preliminary Injunction in American

Interlocutory injunction is an important provisional equity relief in American law. Its sole purpose is to prevent the irreparable harm from happening to the petitioner by holding the status quo before the decision of the merits. Strictures are placed on its process by the necessity for speed and balance among the parties' and public interests. First, the four substantive requirements must be met; then bond is needed; and last there are two review procedures, i.e. appellate procedure and moving procedure, to assure its correctness. In order to accommodate the time urgency and secure the due process, two steps (TRO and preliminary injunction) are devised. All these features of the interlocutory injunction should be studied in and introduced to China.
