Consistency Mechanism*

¹In order to ensure the consistent application of this Regulation throughout the Union, a consistency mechanism for cooperation between the supervisory authorities should be established. ²That mechanism should in particular apply where a supervisory authority intends to adopt a measure intended to produce legal effects as regards processing operations which substantially affect a significant number of data subjects in several Member States. ³It should also apply where any supervisory authority concerned or the Commission requests that such matter should be handled in the consistency mechanism. ⁴That mechanism should be without prejudice to any measures that the Commission may take in the exercise of its powers under the Treaties.
