Criminal Justice and Courts Bill

I was unfortunate enough to practise at the Bar when the previous Government had 13 years and dozens of criminal justice Acts, most of which were highly inefficient and a great bar to proper justice. In relation to judicial review, what was the situation compared with Magna Carta 800 years ago and prior to 1971? We still have a judicial review system, however imperfect the right hon. Gentleman may think it is, and to criticise it as something that Magna Carta would lose by is laughable.
