It is a two-pronged attack. I do not believe that the judges should have the power to make lawful what they have already found is unlawful with retrospective effect. That means that prospective-only orders are, in principle, wrong. However, if there were a case for changing regulations or for altering government action so as to bring it within the limits that Parliament wanted, that is for Parliament; that is for legislation, as the noble and learned Lord, Lord Falconer, argued. It is not for the courts to say, “We find the act unlawful, but it is only going to take effect as unlawful for the future.” It is, in the example of the noble and learned Lord, Lord Brown of Eaton-under-Heywood, an ex tunc approach; but an ex tunc approach, frankly, is right, whereas the removal of flexibility by ruling out the Part A power—the power to delay—would be a removal of flexibility, which would be unnecessary, and we support that. We do not support the presumption, but that is a different point.
The real important point, about retrospective charges and the points in Amendment 6, in the name of the noble Lord, Lord Ponsonby, is that they accept the unlawfulness—if that was the only amendment that was passed—but would go on to say, “You can rely on the unlawfulness as a defence in criminal proceedings and you can still apply for other financial remedies for judicial review, but the quashing order will only take effect prospectively.” That, in my respectful view, is to fudge the whole point of unlawfulness, and the universality and the universal application of judicial review, which lies at its heart.
