European Union (Withdrawal) Bill

Lord Mackay of Clashfern Excerpts

Committee: 4th sitting (Hansard - continued): House of Lords
Monday 5th March 2018 Lords Chamber

[Lord Pannick]

I do not think that the courts have accepted that proportionality can be a challenge by way of judicial review where you are not raising an issue of EU law or convention law—but we have come a very long way towards recognising proportionality as a principle of the common law. That is one reason why I am asking this very important question. I simply do not know whether you can challenge retained EU law after exit day by reference to traditional common law principles.

One reason why this matters is that the Supreme Court, in the HS2 case, suggested that this might be possible under existing law. As was raised in the debate last Monday, we should also bear in mind that, under Clause 2, retained EU law includes statutory instruments that do not owe their legal basis to the European Communities Act. They include statutory instruments enacted through other mechanisms, albeit that they are linked to EU law. At present, one can challenge those instruments by reference to traditional common law principles. Therefore, if Clause 1(1) were intended to prevent such a challenge after exit day, it would be a significant change in the law.

[Lord Mackay of Clashfern (Con)]

Are these questions affected by the proposal to make this particular branch of law statutory? In that case, certain principles of our constitution might cause some difficulty.

[Lord Pannick]

The noble and learned Lord is absolutely right. If retained EU law were to be categorised as primary legislation, such challenges could not be brought. But the Minister resisted that suggestion in our earlier debate. I am concerned with the Bill as it is at the moment. What is the Government’s intention in this respect?
