Re: School Teacher
Per the High Court, there is exactly one law that is special, in that it devolves power to an organization that is not subject to Parliament's sovereignty.
It is the European Communities Act (1972).
It doesn't take much thought to recognize that the Brexiteers (nee Eurosceptics) are in no small part motivated by the power grab aspect: if/when the UK leaves the EU, they'll have unfettered power... even more so if they can drag us out of the ECHR too.
Personally, my level of confidence in the wisdom and moral courage of Westminster is such that I think this is a suboptimal idea.
