If my hon. Friend reads the judgment, he will see that the Court upheld the principle of retention of data as contemplated in the Bill. A number of frameworks on the purpose for which data are retained were referred to, but we are clear that the regime the House is contemplating this evening, in the context of the Bill and how it sits alongside the existing regime of the Regulation of Investigatory Powers Act 2000, does provide a legally robust approach to enable our police, law enforcement and security agencies to combat organised criminality and to provide the national security that is needed. The powers we already use are intrinsic to delivering on that. The Bill makes clear that regulations cannot specify a retention period longer than 12 months. We reflected on the judgment of the Court. As the Home Secretary said in her opening statement on Second Reading, different time periods could be allowed in relation to specific types of data.
We are maintaining that focus on proportionality and necessity not simply in terms of giving a notice, but in keeping it under review. The European Court considered that the period of retention should be based on objective criteria to ensure that it is limited to what is strictly necessary. On the basis of law enforcement surveys in 2005, 2010 and 2012, we consider that a maximum period of 12 months strikes the right balance between the ability of law enforcement and intelligence agencies to investigate crimes and an individual’s rights to privacy. Unlike the current regime, under which all relevant communications data is retained for 12 months, this approach will mean that data could be retained for a shorter period than 12 months if considered appropriate, and that different types of data could be retained for different periods.
