Whether accurate or not (I do not know English law), the original article made the distinction:
Injunction - binding on a party to a suit
Superinjunction - binding on not only the parties, but on everyone else
Hyperinjuction - binding on everyone and equipped with a gag order.
The third is Kafkaesque - because people who are not parties to the suit and discover the facts independently can be held in contempt for publishing them - but are not on notice that publishing them is forbidden. You are not allowed to find out what you cannot say, but you still cannot say it.
