I don't know how many people have heard about this recently, but it has genuinely shocked me to the point that I'm actually going to try contacting my MP about it. A quick summary is that there are (and have been for 6 years though we couldn't be told) powers that the court can grant to have a person all but literally gagged.
The basic case: http://www.thedrum.co.uk/news/2011/03/21/19854-hyper-injunctions-in-the-dock-for-undermining-freedom-of-speech/

An interesting legal thought on the issue: http://www.halsburyslawexchange.co.uk/hyper-injunctions-%E2%80%93-should-the-courts-have-the-power/
I really feel the pressure needs to be kept on Parliament to act on this. When the courts can rule that we cannot speak, then things have got very bad. Furthermore, the only people with sufficient legal clout to actually get such a ruling, are the rich and powerful.
I'm writing to my MP. I'd ask that others do the same, it's as simple as emailing them. They are already aware of it, but we need to keep it high profile.
