I take your point, but is it still reasonable/proportionate to enforce a Court Order against someone who it hasn't been served upon, though? Maybe it's there as a means to add further parties to the Order more readily, as circumstances dictate.
Thinking back, I remember at the time the Giggs super-injunction being widely discussed amongst the great and the good at a particular gathering I was at, including his name being repeatedly and openly used, and no-one seemed to bat an eyelid. I'm not even sure that super-injunction would be enforceable in the terms widely envisaged, otherwise someone would have been subject to proceedings, which they weren't as far as I'm aware. Proportionality is the keyword here and on that basis, it would undoubtedly apply to publications, but not someone down the pub, as that would be wholly disproportionate and surely an infringement of free speech.
My view remains is that part of the Order is practically unenforceable as it stands, although as I've already conceded, I may be wrong on that point and I am perfectly happy to be pointed in that direction by someone better qualified to comment on it than me.
