1. A decision to admit new members shall be taken unanimously by the members of the grouping.

2. Every new member shall be liable, in accordance with the conditions laid down in Article 24, for the grouping's debts and other liabilities, including those arising out of the grouping's activities before his admission.

He may, however, be exempted by a clause in the contract for the formation of the grouping or in the instrument of admission from the payment of debts and other liabilities which originated before his admission. Such a clause may be relied on as against third parties, under the conditions referred to in Article 9(1), only if it is published in accordance with Article 8.
