Lords ChamberThe noble Lord may be right that the vetting process was not sufficient. However, as the regulator said, no reasonable set of quality standards could be guaranteed to prevent this determined malpractice. We are talking about two corrupt people—perhaps there may be more—and the regulator herself said that it would have been very difficult to prevent it.
My Lords, anyone who has practised in the criminal courts, whether prosecuting or defending, will know that confidently given forensic evidence is enormously persuasive when it comes to the issue of guilt or innocence, which is the responsibility of juries. Is not the terrible feature of this that some may have been wrongly convicted or offered pleas of guilty when the evidence put to them simply did not amount to sufficient evidence to justify conviction? This is a serious breach of the civil rights of those who have had to appear in the criminal courts.
The noble Lord is right to point out that confidence in the system is absolutely crucial, and that to date, great confidence has been put in this area of science. He makes the point about somebody being wrongly convicted. It is rare, but not impossible, for someone to be wrongly convicted—but someone is rarely convicted on one piece of evidence, although it is not impossible. That is why the high-priority cases are being looked at and why, in the course of retesting, those sorts of issues will be established. However, the noble Lord is right to point it out.
