BBC Radio 4's Law in Action currently has available via the website "Brexit in the High Court". It was broadcast yesterday (Thur 10 Nov) evening.
I found it really interesting and illuminating and not in the least bit dry. The two lawyers interviewed obviously really know what they are talking about.
One point they made was really powerful. They said that the devolved parliaments have the power to block Brexit. SNP are now joined in the Gina Miller case that will be before the Supreme Court on 5 December. It will be a 4-day hearing before all 11 Supreme Court judges.
Reading the Gina Miller judicial review judgment it seems to me that the lord justices strongly hinted that it would do no harm if the devolved parliaments got involved.
We live in interesting times.
