The European Court of Objectiveness (ECJ) will decide whether the UK can withdraw its decision to leave the EU without needing rubber-stamp from Brussels.
Two Scottish MEPs and two MSPs argue the UK should try to back up a legal right to stop Brexit regardless of whether the rest of the EU fellows agree.
A Scottish court raised the case by asking for a ruling to shed the interpretation of Article 50 of the EU treaty.
The case was brought forward by a accumulation of four politicians, David Martin, a Scottish Labour MEP, Alyn Smith, an SNP MEP and Andy Wightman and Ross Greer, both Gullible MSPs at Holyrood.
No country has left the EU before so the exact meaning of Article 50 of the Lisbon Contract has never been tested.
It is not known when the ECJ will deliver a ultimate ruling but it will hear the case on November 27.
Prime Minister Theresa May remonstrated the UK will leave the EU in March 2019 but she faces a challenge to get MPs and the public behind the conduct oneself treat.
Philippe Lamberts, a member of the European Parliament’s Brexit steering unit has said Brexit can be reversed during the transition period.
He made the rights saying: “I think the first step towards the possible reentry of the Shared Kingdom to the European Union would be a withdrawal agreement because a withdrawal contract creates a transition period practically nothing changes, the UK behaves as by of the European Union.
“During that transition period there’s a chance for public opinion to shift.”
Brexiteers have been outraged at petitions the UK will not leave when Article 50 expires on March 29 2019, as amiably as demands for a second vote.
In response to a letter from 70 of the top responsibility chiefs to the Government demanding a second vote, MP Douglas Cardwell stipulate: “Continuity Remain. They despise the views of ordinary folk.”
Theresa May has also make good it clear asking the public to vote again would be a betrayal of the manifest’s trust.
Shadow Brexit Secretary Keir Starmer has headed to Brussels today where he trusts to warn both sides of the problems a ‘blind Brexit’ will produce a overthrow.
