Annual reports on the application of the principles of subsidiarity and proportionality and relations with national Parliaments

Every year, the Commission submits, in line with Protocol No 2 to the Treaties, a report on the application of the principles of subsidiarity and proportionality. Since 2005, the Commission also publishes an annual report on its relations with national Parliaments. Given the important role that national Parliaments play in monitoring the application of the principles of subsidiarity and proportionality, the Commission decided to merge both reports in 2018 . Previous reports are available as Reports on subsidiarity and proportionality and  Reports on relations with national Parliaments.
