Protection of Freedoms Bill

My Lords, as we have previously discussed, the Bill creates a general rule that all individual samples will be destroyed within six months of being taken. This represents a significant step in protecting the civil liberties of those whose DNA is taken in the course of a criminal investigation, as it ensures that the particularly sensitive genetic material, which is generally not needed for identification purposes, is destroyed at the earliest opportunity. However, as we have proceeded with our consideration of how to implement the provisions of the Bill, prosecutors at the Crown Prosecution Service have made representations to us that, in a limited number of cases each year, it would in fact be necessary to retain the individual samples in order to deal with any subsequent challenge by the defence to the comparison made between the DNA of the individual and that found at the crime scene. Prosecutors are concerned that, if they are not able to retain samples in these cases, they might be unable to withstand such a challenge and acquittals on technical grounds might result. An example of the type of case where such an issue might arise could be where the crime scene stain contained a mixture of, for example, the blood of both a murder victim and their attacker, and possibly a third person, such as an innocent housemate of the victim. In such a sample, the quantity of material from the victim is likely far to exceed that from the attacker and the innocent third party but, without retaining the reference samples from all three individuals, the chemistry and analysis used to derive the three individual profiles, and thus to make a match to the suspect, might be open to challenge in court. Amendment 7 would therefore insert into Clause 14 a mechanism to enable the police, very early in a case before any samples had been destroyed, to make an application to the local magistrates’ court to retain all the individual samples in a case for a period of 12 months. That should be long enough in the majority of cases to identify a suspect and complete the pre-trial disclosure process, as part of which it would be established whether the defence intended to mount a challenge to the derivation of DNA profiles and/or matches. If not, the material would be destroyed at that point. If a suspect had not been identified at the 12-month point, or if the derivation of the profiles and/or matches was still in dispute, the police would be able to apply to the courts to retain the material for a further 12 months, with further such applications available until either the case was concluded or there was no need to retain it any longer. If at that stage a suspect had been identified and criminal proceedings were under way, Section 66 of the Courts Act 2003 would allow the trial judge to deal with the application to continue to retain the samples. I emphasise to your Lordships that we anticipate this procedure being used in only a handful of cases each year, all of which must be serious crimes on the qualifying offences list. While biological samples will be retained following a successful application, those samples will be able to be used only in the case for which they are taken and no extra profiles will be retained on the National DNA Database. Given that the concerns of prosecutors would also apply in respect of the prosecution of those arrested under the Terrorism Act 2000, we are making similar provision in Part 1 of Schedule 1. I turn briefly to the other amendments in this group. Amendment 8 to Clause 17 is technical and confirms that material taken under the regimes in the International Criminal Court Act and the Terrorism Prevention and Investigation Measures Act is not subject to the rules in the Police and Criminal Evidence Act but to the rules in those Acts. The amendments to Clause 18 make it clear that, in respect of a DNA profile, the responsible chief officer is the one whose force took the original sample rather than the one in whose force area the forensic science laboratory is located, while Amendment 14 to Clause 21 removes the definition of the phrase ““law enforcement authority””, which is not used elsewhere in that clause. Finally, I take this opportunity to give notice to the House that we are considering whether it would be helpful to clarify further the scope of the regime for the retention and destruction of material under Section 18 of the Counter-Terrorism Act 2008. If we conclude that further clarification would be helpful, I propose to bring forward further amendments to Schedule 1 to the Bill at Third Reading. Naturally, I will give noble Lords proper notice of any such amendments, should they prove to be necessary. I should have said at the beginning that, in moving Amendment 7, I was speaking also to Amendments 8, 9, 10, 11, 12, 13 and 14.
