Parliament’s exceeded its authority a number of times recently in the name of leftism and attacks on society, and the Crown didn’t stop it but rather gave assent. Some on here defended that with some nonsense about the people revolting against the monarchy if those moves toward libertinism were not given blessing, which shows them to be libertines themselves.
No, unfortunately it hasn't. It's done nothing it doesn't have the constitutional power to do. Just because we don't like it, doesn't make it unconstitutional or beyond its powers. The Parliament has the power.
