In that case, the procedure referred to in Article III-396 shall be suspended. After discussion, the European Council shall, within four months of this suspension, either:

If, by the end of the period referred to in paragraph 3, either no action has been taken by the European Council or if, within 12 months from the submission of a new draft under paragraph 3(b), the European framework law has not been adopted, and at least one third of the Member States wish to establish enhanced cooperation on the basis of the draft framework law concerned, they shall notify the European Parliament, the Council and the Commission accordingly.

In such a case, the authorisation to proceed with enhanced cooperation referred to in Articles I-44(2) and III-419(1) shall be deemed to be granted and the provisions on enhanced cooperation shall apply.
