The UK Government faces a wait until next year to find out whether it has won its Brexit challenge at the UK's highest court.
At the completion of four days of detailed legal argument, 11 Supreme Court justices reserved their ruling until the new year.
Downing Street has accused opponents of Brexit of trying to "frustrate" the will of the British people while tying the hands of those who will negotiate the UK's EU departure.
Prime Minister Theresa May's spokeswoman said the Government was "getting on with the job" when asked about the Labour Party's pledge to amend any Article 50 bill.
The spokeswoman said the Government was "confident" of the appeal case being heard at the Supreme Court over its right to trigger Article 50 as it seeks to provide "certainty" over Brexit.
She added the Government was clear that the Supreme Court would decide the issue, as in all cases concerned with UK constitutional law.
Gripping TV it may not have been but the televised four-day hearing was a box office event for fans of legal argument.
The UK's highest court has been told that a motion in Parliament does not have any bearing on the legal issue it is having to decide.
The Supreme Court is hearing an appeal to overturn a High Court ruling that said the prime minister could not trigger Article 50.
