Article 50
From ACT Wiki
European Union.
'Article 50' refers to Article 50 of the Lisbon Treaty of 2007, which updated the constitutional arrangements of the European Union (EU).
Article 50 outlines a procedure and two-year timetable for negotiation for member states which decide to withdraw from the EU.
It is generally considered that the two-year period will start when the member withdrawing - for example the UK - serves a formal notification of its decision and intention to withdraw.
The notification is often described as 'triggering' Article 50.
