Britain’s Supreme Court has begun a hearing in a case to decide whether parliament should give the government authorization to start the negotiation process to leave the European Union.
The government of Prime Minister Theresa May has asked the Supreme Court judges to overturn a ruling that the government must obtain parliamentary approval before triggering Brexit.
The four-day hearing began on December 5.
Last month, the High Court ruled that the government did not have the executive power alone to invoke Article 50 of the European Union’s Lisbon Treaty to formally start the exit process.
In the appeal hearing, government lawyers argue that the British people have spoken by voting in a June 23 referendum to leave the EU.
The lawyers say that a parliamentary vote would mean getting lawmakers "to answer precisely the same question which was put by parliament to the electorate and has been answered in the referendum."
A verdict is expected in January.
May has said that a parliamentary vote on the legislation would not disrupt her plans to trigger Article 50 by the end of March 2017.
Britons voted by 52 percent to 48 percent to leave the EU.
