(Bloomberg) -- The European Union’s highest court will say next week whether the U.K. should be allowed to reverse Brexit, in a landmark ruling that could offer hope to those who want the country to stay in the bloc.

The EU Court of Justice will issue a ruling on Dec. 10 at 9 a.m. in a case to clarify whether Article 50 can be unilaterally reversed and if not, what the U.K. must do.

Advocate General Manuel Campos Sanchez-Bordona of the Luxembourg-based court said in a non-binding opinion this week that the U.K. can reverse its notice, without conditions attached. A ruling following the advice will embolden those who are fighting to reverse Brexit -- a campaign that’s gathering momentum.

The U.K. Parliament is scheduled to hold a so-called meaningful vote on Prime Minister Theresa May’s withdrawal agreement with the EU on Dec. 11.
