There is a pretty comprehensive summary of the recent Policy Exchange conference on Libel Tourism over at Harry’s Place.
I’d forgotten about this imaginative suggestion from Anthony Julius of Mischon de Reya: “Julius added mischievously that occasionally he is consulted by predatory fabulously wealthy clients, and he advises them: If you want the truth, but don’t want to use your wealth in a coercive system, then why not invite the alleged defamer to a tribunal at no financial risk, where you will pay the costs, thus ensuring the truth is reached in a level playing field. Oddly, no-one has taken up the proposal.”
