My Lords, I begin by very quickly thanking the noble Lord, Lord Foulkes, for his comments—with which I agree entirely—and the noble Lord, Lord Pannick, for his very comprehensive explanation.
In general, Clause 5 is very problematic as drafted. I am grateful for the suggestions that have been made so far. Other colleagues who have spoken on other occasions about this danger in Clause 5 have expressed real concern about it suggesting leaving out the main subsections. Even if Section 1 is not separately debated today, they all come together in a cohesive generality.
The Bill converts existing EU direct law—as has been said, mainly regulations but also directives and sometimes decisions—into UK law as it applies on the actual exit date. I fear that Her Majesty’s Government, who have already shown massive incompetence in handling the whole wretched process of Brexit, underestimate the huge volume of SIs that would need to cascade through the system if enacted as they stand. I feel very strongly that it would not be seemly and proper to incorporate the words of the so-called supremacy of EU law as is written down now, even if there was a laid-down definitional basis. Even the qualified tone in subsections (2) and (3) does not reassure me. Unless the text is improved appropriately, I envisage endless scenes of parties arguing in UK courts over the underlying meanings—arguments for some length of time and at notable expense, of course.
Many outside expert observers of these matters—including, I recall, the Law Society—have flagged up these possible consequences. There have also been suggestions of them in various quarters, not least in our House’s Constitution Committee. The principle of the famous Clause 2 in the original 1972 EU membership Bill should be invoked to decide on the solutions—albeit for the reverse objective and in the reverse direction—to mitigate these dangers and provide the cover-all effect needed to avoid unnecessary litigation and post-Brexit wrangling.
I conclude by emphasising that taking part in these irritating and, dare I say, excessively bureaucratic legislative procedures in no way implies my support for the Government’s foolish, relentless, drive for a nightmare Brexit that fewer and fewer people in the UK now want. That is why I support the symbolic resistance of the noble Lord, Lord Adonis, to all the clauses standing part, including Clause 5.
