My Lords, I take this opportunity to further reassure noble Lords that proportionality is a concept that has a continuing role in the Bill. Not only will the obligations in the GDPR carry over to domestic law but they will continue to apply to the Government. If Ministers are minded to use the powers in Clauses 10 or 16, for example, that allow new processing conditions or exemptions to be created in the future, they will need to continue to be proportionate. Further, the courts will continue to apply a proportionality test where appropriate. The Human Rights Act ensures that any public body must act compatibly with the convention, and as data protection is within Article 8 —the right to privacy—the public authority must act proportionately.
Clause 6 of the EU withdrawal Bill has the effect that any question as to the validity, meaning or effect of any retained EU law, including the GDPR, is to be decided, where relevant, in accordance with any retained case law and any retained general principles of EU law. Proportionality is one of those retained principles, so it will live on for as long as this legislation is in force.
Indeed, leaving the EU will not shake proportionality out of our legal system—it has worked its way into public law. Any public body acting disproportionately must be at risk of being challenged. Whenever any public body acts, it must act compatibly with the convention rights. Where qualified rights are concerned, such as Article 8 of the convention, which has been held to encompass personal data protection, there exists a requirement for that action to be a proportionate means of achieving a legitimate aim. So to that extent it is implicit that the Executive as well as data controllers must act in a proportionate manner. With that explanation, I invite the noble Lord, Lord Stevenson, not to press his Amendment 3.
