I am going to make a little bit more progress. I have given way to my hon. Friend. The singling out of these areas of law appears somewhat arbitrary, given other fields the amendment might equally apply to. It would lead to a splintered approach to interpretation of the law and a fragmented UK jurisprudence-more uncertainty, not less. In any case, it is totally unnecessary. The UK has a proud history of ensuring the rights and protections of individuals in this country. The UK has high standards of protection domestically in relation to workers' rights and human rights. We are recognised as a world leader in delivering robust, rigorous health and safety protections. That record and that commitment is not dependent on our membership of the EU; it is dependent on hon. Members in this House and their eternal vigilance. It will continue to be dependent on that after we leave. I hope that the right hon. Member for Islington North (Jeremy Corbyn) and his colleagues in the Labour party will not press amendment 306. Finally, I turn to amendment 358 tabled by the Chair of the Justice Committee, my hon. Friend the Member for Bromley and Chislehurst (Robert Neill), which sets out the ability of UK courts to have regard to material used in the preparation of retained EU law. I hope that this is the point at which I give some reassurance to my right hon. and learned Friend the Member for Beaconsfield (Mr Grieve) and my right hon. Friend the Member for West Dorset (Sir Oliver Letwin). Currently, when interpreting EU law domestically, our courts will look at the language used, as well as considering the legislation's recitals, legal basis and other language versions to inform their interpretation. We do not want to change how this law is interpreted or to create any fresh uncertainty about its meaning, so the Bill provides for the courts to continue that approach. Clause 6 provides that questions on the validity, meaning or effect of retained EU law will be decided in accordance with retained case law and general principles of EU law. This requires taking a purposive approach to interpretation where the meaning of the provision is unclear, considering relevant documents such as the legislation's treaty legal base, working papers that may have led to the adoption of the measure and the general principles of EU law. I hope that reassures my hon. Friend the Chair of the Select Committee and that he will not press his amendment.
