Article 3
1. The Commission shall continuously monitor the application of the legal framework that is the object of this Decision, including the conditions under which onward transfers are carried out, individual rights are exercised and U.S. public authorities have access to data transferred on the basis of this Decision, with a view to assessing whether the United States continues to ensure an adequate level of protection as referred to in Article 1. 2. The Member States and the Commission shall inform each other of cases where it appears that the bodies in the United States with the statutory power to enforce compliance with the Principles set out in Annex I fail to provide effective detection and supervision mechanisms enabling infringements of the Principles set out in Annex I to be identified and punished in practice. 3. The Member States and the Commission shall inform each other of any indications that the interferences by U.S. public authorities responsible for the pursuit of national security, law enforcement or other public interests with the right of individuals to the protection of their personal data go beyond what is necessary and proportionate, and/or that there is no effective legal protection against such interferences. 4. After one year from the date of the notification of this Decision to the Member States and subsequently at a periodicity that will be decided in close consultation with the Committee established under Article 93(1) of Regulation (EU) 2016/679 and the European Data Protection Board, the Commission shall evaluate the finding referred to in Article 1(1) on the basis of all available information, including information obtained through the review carried out together with the competent authorities of the United States. 5. Where the Commission has indications that an adequate level of protection is no longer ensured, the Commission shall inform the competent U.S. authorities. If necessary, it will decide to suspend, amend or repeal this Decision, or limit its scope, in accordance with Article 45(5) of Regulation (EU) 2016/679. The Commission may also adopt such a decision if the lack of cooperation of the U.S. government prevents the Commission from determining whether the United States continues to ensure an adequate level of protection.
