Today Advocate General Campos Sánchez-Bordona has given an opinion[1] that Article 50 TEU allows the unilateral revocation of the notification of the intention to withdraw from the EU, until such time as the withdrawal agreement is formally concluded, provided that the revocation has been decided upon in accordance with the Member State’s constitutional requirements, is formally notified to the European Council and does not involve an abusive practice. Revocation is only possible within the two year period that starts when the intention to withdraw is notified.
The decision of the Court of Justice on this matter is expected later this month.
