1. Member States shall, where two or more controllers jointly determine the purposes and means of processing, provide for them to be joint controllers. They shall, in a transparent manner, determine their respective responsibilities for compliance with this Directive, in particular as regards the exercise of the rights of the data subject and their respective duties to provide the information referred to in Article 13, by means of an arrangement between them unless, and in so far as, the respective responsibilities of the controllers are determined by Union or Member State law to which the controllers are subject. The arrangement shall designate the contact point for data subjects. Member States may designate which of the joint controllers can act as a single contact point for data subjects to exercise their rights.

2. Irrespective of the terms of the arrangement referred to in paragraph 1, Member States may provide for the data subject to exercise his or her rights under the provisions adopted pursuant to this Directive in respect of and against each of the controllers.
