Allegations of various sorts of inappropriate behaviour were made by several employees of Philip Green. These claims were settled and the settlements included NDAs. There is no allegation that these NDAs were improperly obtained (i.e. proper legal advice was obtained by the employees).
The media were prevented from revealing Philip Green's name by an injunction. (I don't know how they found out about it, perhaps that is relevant). Lord Hain used parliamentary privilege to reveal that the stories were about Philip Green and consequently the press are now free to talk about it.
My question is: given that the NDAs were between the employees making the allegations and Philip Green on what basis did the courts prevent the media from revealing his name? They were not party to the NDAs so surely cannot be bound by their terms. Presumably I'm free to tell my friends if I think its Philip Green, what's the difference? Could he take out an injunction against me?
For the purposes of this question please ignore the rights and wrongs of the NDAs or the use of parliamentary privilege.
