Injunction

n.
  1. The act of enjoining; the act of directing, commanding, or prohibiting.
  2. That which is enjoined; an order; a mandate; a decree; a command; a precept; a direction.
  3. (Law) A writ or process, granted by a court of equity, and, in some cases, under statutes, by a court of law, whereby a party is required to do or to refrain from doing certain acts, according to the exigency of the writ.

It is more generally used as a preventive than as a restorative process, although by no means confined to the former.
