GDPR provisions impose on supervisory authorities obligations related to cooperation and consistency mechanism prescribed in Chapter VII. The introduction of a cooperation mechanism was one of the key elements of the data protection reform as it seeks to ensure the consistent application and enforcement of GDPR in the internal market.
Thus, Articles from 60 to 63 of GDPR entail obligations to cooperate with other authorities established in Member States, especially in situations referred to in Article 56 of GDPR when one-stop-shop mechanism may be applied, provide each other with relevant information and mutual assistance, conduct joint operations including joint investigations and joint enforcement measures and cooperate through the consistency mechanism.
