Where Part III provides for the Council to act by unanimity in a given area or case, the European Council may adopt a European decision authorising the Council to act by a qualified majority in that area or in that case.

This paragraph shall not apply to decisions with military implications or those in the area of defence.

Any initiative taken by the European Council on the basis of paragraphs 1 or 2 shall be notified to the national Parliaments. If a national Parliament makes known its opposition within six months of the date of such notification, the European decision referred to in paragraphs 1 or 2 shall not be adopted. In the absence of opposition, the European Council may adopt the decision.

For the adoption of the European decisions referred to in paragraphs 1 and 2, the European Council shall act by unanimity after obtaining the consent of the European Parliament, which shall be given by a majority of its component members.
