Protection of Freedoms Bill

My Lords, my noble friend is again right when she says that there are some technical problems with this issue. I shall say a little about that in a moment once I have set out the position. It might help if I set out a little of the background in this area. Because of the way in which DNA samples have historically been processed in batches—typically of 96, I am told—it is impractical to delete all processing records held within a forensic science laboratory, as batches will inevitably contain a mixture of profiles from convicted and unconvicted individuals, and records must be retained for evidential purposes of convicted individuals, not least in the event of a subsequent appeal or referral to the Court of Appeal by the Criminal Cases Review Commission. Action is already under way, led by the National DNA Database Strategy Board and the Protection of Freedoms Bill Implementation Project Board, chaired by Chief Constable Chris Sims on behalf of ACPO, to address the potential for relinking records by removing any link between police barcode numbers and laboratory processing records. One forensic science provider already does this. The strategy board is already working with the laboratories to make this change by the middle of next year. This will break the link between the police and laboratory records and prevent any illicit relinking of names to profiles. The revised procedures will apply to both new and existing samples. From mid-2012, it will be impossible to carry out this relinking. Once the forensic science provider is informed that an individual’s DNA profile has been removed from the database, the link between the police barcode and the laboratory reference will be broken and restoration will not be possible. None the less, we understand the concerns that have been expressed in this area, and my honourable friend the Minister for Crime and Security recently met representatives of the company which supplies the DNA profiling machines which produce these interim records. They are working on a proposal to enable the deletion of these records rather than merely breaking the links as I have described. If the cost of doing so is not wholly excessive, we will require the destruction of these records. I hope that my noble friend will bear with me for a while until those discussions have been completed and the company can tell us what will be physically possible and what will not be possible. In the mean time, I hope that she will be satisfied by the fact that we feel that we can break the link between the police barcode and the laboratory reference. Once we have broken that link, it will not be restored. Therefore, Amendment 21 will not be necessary.
