From DMcG on another thread today:

""Lower courts can roll back EU laws after Brexit, No 10 confirms"

It will be interesting to see how this one plays out. The reason given is that the Government does not want roll back of these laws to be stuck in the Supreme Court due to it being overloaded. But surely if such a law is (or is not) repealed by a lower court, in many cases this will immediately lead to the judgement itself being appealed? Which will, ultimately, end up at the Supreme Court anyway?   The only way I can see of avoiding that is to find some way of limiting the appeal process, which is itself a substantial reduction in citizen's rights."
