Re: The Sooner...
"Brexit has nothing to do with this."
Not specifically with this case, but the principals are involved in Brexit.
Assuming we leave the jurisdiction of both the ECJ and the ECHR, the final arbiters of our rights will be the UK courts, and the ones who decide which rights we have will be the UK government. Given their record on such matters (both parties), I find it worrying that there will be no external body to oversee this. I expect that our rights will be whittled away, one by one, with noone able to stop it*.
* Yes, I know we can vote in a different government. However, looking at the records of MPs, as soon as they get into power they abandon anything but the vaguest pretence at maintaining rights and start removing them. Even so, a lot of damage can be done in the 5 years between General Elections...
