'An intellectual contest'
By Dominic Casciani, BBC Home Affairs Correspondent
Day one of the hearing was exactly the kind of scenario that the Supreme Court was set up to answer: the biggest question of the day - if not decades.
Inside court one, we had the unprecedented scene of 11 justices and some of the beefiest legal teams in the country.
Proceedings were, like many Supreme Court hearings, an intellectual contest conducted with warmth, civility and good humour - an examination of what the UK's uncodified constitution means.
Outside it was different - protesters from both sides. Some good humoured, some not. One shouted "traitor" at Gina Miller as she left court, having exercised her legal right to challenge the government.
Who's winning? Hard to tell.
After lunch the justices gave the government team a tough time - but at this level you can't read anything into that.
That's what they are there to do: test to the limits the claims being made, define the line and uphold the rule of law that protects our democracy.
The government has said it will trigger Article 50, which begins two years of formal talks, by the end of March.
It says it can do this using ancient "prerogative" powers but campaigners argue authorisation should come from Parliament, leading to the battle in the courts.
On Monday Attorney General Jeremy Wright argued the powers the government wants to use to trigger Article 50 were not a "relic" but a "fundamental pillar of our constitution as a sovereign state".
The government's top lawyer, James Eadie QC, also argued that Parliament could have chosen to limit ministers' power to trigger Article 50 but had chosen not to.
Lord Pannick QC - a crossbench peer - will be putting forward Ms Miller's case.
A verdict from the 11 justices is expected in January.
