With respect to the hon. Lady, it is seldom persons in that category who are the interveners; they are much more likely to be the bringers of the review. I will come to the role of interveners in a moment, but let me finish the point about the way in which there has been mission creep in judicial review and the sometimes damaging effect that that has on the decision-making process.
The situation is a little like what we found with local government finance at one time, when officials tended to play tick the box so that someone qualified for the right number of grants. There is an element of that sometimes in the decision-making process, where decisions are always taken with an eye over the shoulder at the risk of judicial review rather than getting to the merits of the matter. If these clauses help, as I think they will, to move away from that culture, that is a good thing, as it will then encourage imaginative and radical, but always fact-based, decision making. It will always have to be fact-based because, after all, the Wednesbury reasonableness test is unchanged; it remains in any event. There will always be scope for challenge of irrational decisions, or of decisions that are genuinely not based on evidence. But removing the threat of judicial review to the extent that it now hangs over decision makers is sensible and proportionate.
