My Lords, I suppose I should declare a professional interest in the possibility of Miller 3.
I support the amendments in the names of the noble Lords, Lord Norton and Lord Butler. I do not suggest that the courts would today never entertain a judicial review in relation to Dissolution. The noble Lord, Lord Norton, mentioned the words of Lord Roskill in the GCHQ case in 1984—the law has moved on a long way in the nearly 40 years since then. Like other noble Lords, I find it very difficult to envisage a case in which the courts would entertain a challenge to the Dissolution of Parliament and the calling of a general election. However, I support the amendments because I think it would be wise, in this context, to proceed on the basis of never say never.
One of the vices of a provision such as Clause 3 is that it seeks to remove the possibility of the court exercising jurisdiction, however exceptional the circumstances may be or however grave the abuse of power by a future Prime Minister. I would much prefer to leave it to the judgment of a future Supreme Court whether the circumstances then existing justify exceptional judicial involvement and whether there is an abuse of power, rather than confirm a blanket immunity from legal challenge whatever the circumstances.
I also agree with the noble Lords, Lord Butler and Lord Norton, that there is a point of principle here: the Prime Minister would be exercising a very important power. It is wrong in principle that there should be an immunity from the rule of law—it is a very basic principle. That principle does not depend on whether the noble Lord, Lord Faulks, is correct in saying that, as a matter of description, this is or is not an ouster clause. What it purports to do is prevent the court saying, “What you have done is unlawful”. We should not be allowing the exercise of public powers to enjoy such immunity as a matter of principle.
We then have the argument the noble Lord, Lord Faulks, deployed, and which was raised in Committee, that the mere existence of this possible jurisdiction to entertain a judicial review may cause delay, expense or inconvenience. That seems to me to be entirely unrealistic. I looked to see whether there have been any cases analogous to the possible cases we are talking about. There is one. The Press Association reported on 8 April 1992, the day before the 1992 general election— won by John Major—that on 7 April, the day before, Mr Justice Macpherson had considered and rejected a judicial review application which was made by a Mr George Barnes, who was seeking to stop the 1992 general election going ahead. Mr Barnes was aggrieved by the manner, as he put it, in which the main political parties had chosen their candidates.
