This Directive shall be without prejudice to the fulfilment of any obligation to provide wider assistance ensuing from bilateral or multilateral agreements or arrangements, including for the notification of legal or extra-legal acts.

Where the Member States conclude such bilateral or multilateral agreements or arrangements on matters covered by this Directive other than to deal with individual cases, they shall inform the Commission thereof without delay. The Commission shall in turn inform the other Member States.

When providing such greater measure of mutual assistance under a bilateral or multilateral agreement or arrangement, Member States may make use of the electronic communication network and the standard forms adopted for the implementation of this Directive.
