There has been plenty of discussion, and involving the ECHR, whether media speculation about potential proceedings or just active proceedings should be curtailed and strict liability imposed for contempt of court.
The upshot was that strict liability curtailing the publication of documents should generally be imposed in respect of active proceedings only.
I am not aware in the current case that proceedings are "active".
In the event there were to be active proceedings, I doubt very much that some of the more pejorative and uninformed posts on this forum would find themselves being used in those proceedings.
So whilst one might have the view that some posts here push the limits of decency, the law does little to deter such posts.
