Parole Board (Amendment) Rules 2022

My Lords, with respect, I have always understood it to be the case—I hope I have not got this wrong—that an expert should not normally give his opinion on the very issue on which the court is required to decide. The scope of the expert’s opinion is to provide the court with the factual details. It is the duty of the expert not to say whether X or Y is guilty or not guilty but to provide the court with the facts on which that decision is taken. At least, that is common practice.
