Even broader is the one in the drafted repeal of the Fixed-Term Parliaments Act, the scope of (b) being particularly worrying - what exactly counts a related purported decision? 'A court of law may not question— (a) the exercise or purported exercise of the powers referred to in section 2,(b) any decision or purported decision relating to those powers, or (c) the limits or extent of those powers.'

My take is that this means the courts may not question any legal exercise of those powers sure, but if the exercise of the powers is found to be contrary to law then it is void and subject to judicial review. And that’s fine, there shouldn’t be any way to bypass judicial review.
