Bericht der Kommission: Jahresbericht 2017 über die Anwendung der Grundsätze der Subsidiarität und der Verhältnismäßigkeit KOM(2018) 490 endg.; Ratsdok. 13537/18

This report examines how the European Commission applied the principles of subsidiarity and proportionality in its legislative proposals during 2017. These principles ensure that the EU only acts when it is more effective than national, regional, or local action, and that its actions do not exceed what is necessary to achieve the objective. This procedure affects EU member states and national parliaments, as it provides a mechanism for monitoring whether the EU is overstepping its authority or interfering unnecessarily in national competencies.
