My hon. Friend is exactly right. These common-sense measures could have a dramatic impact on the way our mental health units work, and for the well-being of both staff and those who are there receiving treatment.
Another important aspect of the Bill is the proposal that justice for a potential victim would now become possible. Our country and our values are based on the rule of law, but for justice to be done we need a new and open approach which would allow our public services to learn from past mistakes and ensure that no family or individual has to suffer the tragedy of loss or injustice that has too often been experienced by patients and their families. I have a constituency case in which a young girl had been put in restraint, not within a mental health unit, but within a special school environment, and, as a result of the fits from which she suffered, she hit her head and lost her sight. That is truly tragic, and the family has fought and fought to find a way to get redress and a better educational framework for this child to learn, having developed this entirely avoidable blindness. There is a great challenge in ensuring that we have a system that is open and transparent, and that families can be heard and do not have to fight for years.
