My Lords, as I was saying, as my noble friend Lord Hailsham, whose father I greatly respected as a colleague of mine in government, has reminded us, the reason we are debating this proposed new clause today is that the noble Lord,
Lord Pannick, who moved this amendment, convinced first the High Court and subsequently a majority of the Supreme Court that a Bill is needed and that the Government’s intention to rely on the prerogative will not do. His argument was clear, and I think it will be helpful if I remind the House of it by quoting his words before the High Court:
“my case is very simple. My case is that notification is the pulling of the trigger and once you have pulled the trigger, the consequence follows. The bullet hits the target. It hits the target on the date specified in Article 50(3). The triggering leads to the consequence, inevitably leads to the consequence, as a matter of law, that the treaties cease to apply”.
In short, the very act of invoking Article 50 inexorably leads to Brexit two years later. This was the principal basis on which the courts decided that the Government were wrong to rely on the prerogative, yet the proposed new clause appears to say exactly the opposite. It says that there is no inevitability at all. Triggering Article 50 does not “inevitably”—in the own word of the noble Lord, Lord Pannick—lead to Brexit, for the explicit purpose of the proposed new clause is to ensure that even when Article 50 has been invoked, if Parliament disapproves of the outcome of the negotiations it can stop Brexit happening. Indeed, as a number of speakers have pointed out, on the strict interpretation of the proposed new clause, your Lordships’ House alone can prevent Brexit since the approval of both Houses is required. I do not want to go down that avenue because I have not time.
I have the greatest respect for the noble Lord, Lord Pannick, as an exceedingly clever lawyer who deploys his cleverness with considerable charm. However, is it possible for even him to have his cake and eat it? Might this not be too clever by half? The real mischief—
