Today the landmark hearing over whether the Government can use the royal prerogative or requires Parliamentary approval to trigger Article 50 began in the Supreme Court.
On occasion, the press can be accused of exaggerating the significance of a particular story, but in this instance the constitutional importance of the case cannot be overstated. This was evidenced by the world's press gathered outside the Supreme Court this morning and all 11 Supreme Court Justices hearing the case together.
Allowing ministers to trigger Brexit was Parliament's "clear expectation" when it agreed to an EU referendum, the Supreme Court has been told. Attorney General Jeremy Wright said the government would be making "lawful" use of "fundamental" powers by triggering Article 50 of the Lisbon Treaty. He was speaking at a legal hearing into whether Parliament's consent was needed before Brexit negotiations begin. The High Court ruled in October that MPs did need to give the go ahead.
