The High Court has decided that Prime Minister Theresa May cannot trigger Brexit without an Act of Parliament - but what are the legal ramifications of this ruling?
This week, Joshua Rozenberg explores this latest chapter in Britain's exit from the EU - the fallout from which has seen highly personal attacks on England's most senior judges, as the ideological divisions seen in the run up to the referendum vote were exposed once more.
Following our previous edition of Law in Action, which aired straight after the referendum vote, the programme has gone back to the same leading legal minds to seek some clarity amid the conflicting and confusing media coverage.
Has the high court's decision really stalled Brexit as leave voters fear - and some remainers hope? Just how will the so-called 'Great Repeal Bill' work in practice? And will the UK still have to comply with EU laws if it wants to continue to trade with the continent?
