I too support this amendment. I was really surprised that there is not already a standard and that this is not consistent across the criminal justice system. When the noble Baroness, Lady Coussins, explained that the Metropolitan Police had already taken the lead on this, I was hoping that that was during my time, but it was not. However, I think this is a good idea. This is about not only high and consistent standards but experience—experience within the criminal justice system will be relevant at various times—and integrity. These people will have access to private and confidential information. For all those reasons, it is important that there is a consistent, high standard.
Each part of the system, whether the police, prosecutors, defence, courts, judge or jury, requires this to happen consistently. It seems amazing that at the moment they are not able to rely on the same interpretation or translation of the same material. That seems odd. At least in the case of the police, you can go back and check some of the original evidence. Body-worn video, CCTV or audio recordings of the interview might be available, so someone can go back and check. However, as far as I am aware, that is not the case in court. There is a written record, but that in itself is open to interpretation and is not always entirely accurate.
There are things that feed into the criminal justice system which are also important and rely on the contribution of the individual and what they say, for example psychiatric assessments. These can be vital in determining whether someone is guilty or so psychiatrically ill that they should not be held guilty for their actions and in determining what actions will follow a sentence.
This is not a minority issue, particularly in London. The last time I saw the figures, around 27% of the 250,000 arrests carried out by the Metropolitan Police every year are of foreign nationals. There is then at least a risk that they are speaking a second language, not their first, which imposes certain challenges on the whole system. It is vital that they, as well as witnesses and all the other people who play a vital role in the criminal justice system, are able to be heard.
Finally, it seems to me that this is particularly pertinent in an adversarial system which relies an awful lot on cross-examination. Are mistakes made in court? Is consistency observed between the original account and those given by various witnesses? Language is very important. We would all say so, but I would say it is even more important in an adversarial system, which sometimes seeks to cause inconsistency in the account that is given. This creates an even bigger burden for the system to make sure that the account of the language is of the highest standard available. It is important that the Government create such a system, so I support this amendment.
