Web Blocking Policy made behind closed doors?

Is it appropriate for web-blocking proposals to be agreed behind closed doors? Earlier this week, documents from a closed-door meeting between Minister Ed Vaizey and a rightsholders group that included the Premier League, the Publishers Association, BPI, Motion Picture Association and others were leaked to blogger James Frith. The leaked papers from the meeting imply that the rightsholders would like to bring in a voluntary web-blocking scheme that would act as a ‘self-regulation’ system allowing rightsholders to quickly block websites without thorough legal intervention.
