Question to the Department for Exiting the European Union :

To ask Her Majesty’s Government what advice they have received on whether the European Court of Justice has any jurisdiction over the manner and timing of the triggering of the use of Article 50 of the Lisbon Treaty.

Article 50 of the Treaty of the European Union states that 'any Member State may decide to withdraw from the Union in accordance with its own constitutional requirements' and 'shall notify the European Council of its intention'. It is for the Member State concerned to determine what its constitutional requirements are​. ​​T​he manner in which​ the​ notice is given - to the European Council​ - is clearly set out​ in Article 50 itself.​ On the timing, the Prime Minister has been clear that we will notify by the end of March 2017.​
