My Lords, this is another amendment that comes from the Constitution Committee. It suggests that we should exclude from the scope of Clause 4 any EU law rights derived from the 1972 Act which are already the subject of an enactment—in other words, where Parliament has already dealt with the subject. The Constitution Committee explained its concern at paragraph 35 of its report.
The concern is this. Clause 4 as drafted would include, within retained EU law, rights and obligations under EU law irrespective of whether they have already been implemented in domestic law by primary or secondary legislation. The problem to which this gives rise is that, as a result of Clause 4, there may be, as part of our law after exit day, two conflicting sets of legal rights on the same subject: the ones already implemented by Parliament and the greater rights which a litigant will say are derived from retained EU law. The question is: how is the court supposed to deal with that conflict? It has two retained EU law rights on the same subject. The Constitution Committee heard evidence from the noble and learned Lord, Lord Neuberger of Abbotsbury, the former President of the Supreme Court. As set out in the report, he told the committee that this problem needs to be addressed by the Bill.
Paragraph 36 of the report mentions that the committee heard evidence from the Department for Exiting the European Union that suggested that the problem that I have sought to explain is no different from the situation under the current law where there may be a statute which has sought to implement an EU law obligation that is found by a court judgment not fully to have implemented the EU law obligation, so the EU law obligation takes priority over the inadequate domestic implementation. The problem is that under the Bill, both the domestic enactment and the EU law obligation —see Clauses 2 and 4 respectively—are treated as
retained EU law, so the supremacy principle under Clause 5, to which we will come, applies to both of them, and the question remains: which of them takes priority? I look forward to hearing the answer from the Minister to this difficulty. I beg to move.
