All eleven judges of the Supreme Court will meet today to hear the governments case that the High Court ruling on Article 50 should be overturned. If the Court upholds the High Court's previous verdict, it means Prime Minister Theresa May will be required to pass an act of parliament before triggering Article 50, the legal mechanism to leave the EU. Will the judges side with Prime Minister Theresa May? Or with the investment manager Gina Miller who began all this? She's backed by expertise from lawyers Mishcon de Reya and David Pannick QC, a cross-bencher in the Lords, and co-author of Human Rights Law and Practice. Michael Bowsher QC of Monckton Chambers joined Share Radio to discuss.
