The enhanced cooperation authorised by this Decision is open at any time to all Member States that want to participate in it under the terms set out in this Decision. Any newly participating Member State in the enhanced cooperation should contribute to the financing of the expenditure of the enhanced cooperation from the date on which the participation of that Member State becomes effective pursuant to Article 331(1) TFEU.
