Why?
Because it's total BS and a unilateral decision by that commissioner.
The Lisbon Treaty full text (I've just downloaded from the EU site), reads:
The following new Article 49 A shall be inserted:
‘Article 49 A
1. Any Member State may decide to withdraw from the Union in accordance with its own
constitutional requirements.
2. A Member State which decides to withdraw shall notify the European Council of its
intention. In the light of the guidelines provided by the European Council, the Union shall
negotiate and conclude an agreement with that State, setting out the arrangements for its
withdrawal, taking account of the framework for its future relationship with the Union. That
agreement shall be negotiated in accordance with Article 188 N(3) of the Treaty on the
Functioning of the European Union. It shall be concluded on behalf of the Union by the
Council, acting by a qualified majority, after obtaining the consent of the European Parliament.
3. The Treaties shall cease to apply to the State in question from the date of entry into force
of the withdrawal agreement or, failing that, two years after the notification referred to in
paragraph 2, unless the European Council, in agreement with the Member State concerned,
unanimously decides to extend this period.
C 306/40 EN Official Journal of the European Union 17.12.2007
4. For the purposes of paragraphs 2 and 3, the member of the European Council or of the
Council representing the withdrawing Member State shall not participate in the discussions of
the European Council or Council or in decisions concerning it.
A qualified majority shall be defined in accordance with Article 205(3)(b) of the Treaty on the
Functioning of the European Union.
5. If a State which has withdrawn from the Union asks to rejoin, its request shall be subject
to the procedure referred to in Article 49.’.
The Constitution says
Article I-60
Voluntary withdrawal from the Union
1. Any Member State may decide to withdraw from the Union in accordance with its own
constitutional requirements.
2. A Member State which decides to withdraw shall notify the European Council of its intention. In
the light of the guidelines provided by the European Council, the Union shall negotiate and conclude
an agreement with that State, setting out the arrangements for its withdrawal, taking account of the
framework for its future relationship with the Union. That agreement shall be negotiated in
accordance with Article III-325(3). It shall be concluded by the Council, acting by a qualified
majority, after obtaining the consent of the European Parliament.
3. The Constitution shall cease to apply to the State in question from the date of entry into force of
the withdrawal agreement or, failing that, two years after the notification referred to in paragraph 2,
unless the European Council, in agreement with the Member State concerned, unanimously decides
to extend this period.
4. For the purposes of paragraphs 2 and 3, the member of the European Council or of the Council
representing the withdrawing Member State shall not participate in the discussions of the European
Council or Council or in European decisions concerning it.
A qualified majority shall be defined as at least 72 % of the members of the Council, representing the
participating Member States, comprising at least 65 % of the population of these States.
5. If a State which has withdrawn from the Union asks to rejoin, its request shall be subject to the
procedure referred to in Article I-58.
It is impossible for the EU to negotiate an agreement for exit,
taking account of the
framework for its future relationship with the Union, without negotiating its trade relationship.
So she's lying and that's why nobody mentioned it.
And this is why I AM TOTALLY AGAINST THE EU IN IT'S CURRENT FORMAT.
Because these commissioners can come away with this kind of drivel and expect it to be taken at face value.
EU; one lie after another after another.
