He told The Telegraph: “It talks about the use of psychological or emotional pressure. The problem with that is, when you’re having very sensitive discussions between, for example, parents and their children, or clinicians and their patients, it’s very difficult to understand what that means.”There’s a basic principle called legal certainty, which is a very important part of the rule of law, which means that people need to understand when they are breaking the law and when they’re not breaking the law.”He added: “But I think those concepts of psychological or emotional pressure mean that it would be very difficult for parents to know when they’re talking to their children or for clinicians to know when they’re talking to their patients, whether they’re breaking the law or not.”And that is obviously an unacceptable situation. It’s completely contrary to the rule of law.”
