My take on it is, we have an unelected Prime Minister, who, quite rightly doesn't want to let the EU know what form the Brexit strategy will take.
She failed when she made out that the whole issue would be kept away from public scrutiny, (MP's/Europe), until the exit plan is finalised.
The problem with this is there would appear to be a hidden tier of government, who don't trust the rest of the elected parliament or their opinions.
The "3 Judges" were only pointing out, that this is not the way a democracy rolls, I doubt they would be stupid enough to try and overturn the decision made by the country, via a referendum.
That would be tantamount to lighting the revolution touchpaper...!
Much like America tomorrow, either way.
