What is the difference with a Prohibiting order?

A prohibiting order is similar to a quashing order in that it prevents a tribunal or authority from acting beyond the scope of its powers. The key difference is that a prohibiting order acts prospectively by telling an authority not to do something in contemplation. Examples of where prohibiting orders may be appropriate include stopping the implementation of a decision in breach of natural justice, or to prevent a local authority licensing indecent films, or to prevent the deportation of someone whose immigration status has been wrongly decided.
