Answer: AN INJUNCTION.
Explanation: Injunction means an act of directing with authority, commanding, or prohibiting.
An injunction, legally means a process, granted by a court of justice, and, in some cases, under statutes, by a court of law, whereby an individual is required to do or to refrain from doing certain acts, according to the requirements of the situation of the written order.
From these definitions above, an injunction can simply be defined as an order directing someone to do something or to refrain from doing something.
A cour of justice or a court of law is responsible for granting injunctions and does so with all its backing powers.
