Parliament's resolution on subsidiarity and proportionality reaffirms these principles and calls for stronger involvement of national parliaments in EU law-making. It urges the Commission to improve impact assessments, justify legal bases, and engage national parliaments earlier, including via a single subsidiarity hub. It proposes extending deadlines for reasoned opinions, creating a green card, and strengthening the role of regional parliaments. It calls for better judicial enforcement by the CJEU and for closing loopholes in legislative transparency.

Key points

  1. Reaffirms the fundamental importance of subsidiarity and proportionality for the EU's legal and institutional framework.
  2. Calls on the Commission to revise the legal basis of the ReArm Europe Plan/Readiness 2030 instrument, which uses Article 122 TFEU.
  3. Demands rigorous ex ante impact assessments and justification for harmonisation, and regrets that the subsidiarity grid is not yet used.
  4. Urges the Commission to conduct more systematic subsidiarity analysis and provide detailed justifications in each proposal.
  5. Calls for extending the deadline for yellow card procedures to 12 weeks and creating a 'green card' with lower thresholds.
  6. Encourages national parliaments to include reasoned opinions from regional parliaments with legislative powers.
  7. Stresses the CJEU's crucial role but notes its reluctance to enforce subsidiarity, and calls for impact assessments without exception.
  8. Proposes opening a discussion on creating a 'subsidiarity court' for future Treaty revision.
  9. Demands closing loopholes for greater transparency in legislative preparation, including earlier engagement with national parliaments.
  10. Endorses the Draghi report's conclusion to focus EU action where it has greater added value and adopt self-restraint in policymaking.
  11. Suggests using artificial intelligence to find legal inconsistencies or disproportionate effects in legislation.
  12. Commits to using the right of initiative under Article 225 TFEU to propose repealing legislation to reduce regulatory burden.

Who is affected

  • National parliaments: encouraged to enhance scrutiny and use yellow/orange cards; may get extended deadlines and a green card.
  • Regional parliaments with legislative powers: their reasoned opinions should be included by national parliaments; right to be informed suggested.
  • Municipalities: need sufficient financial resources to implement EU law, especially in remote areas.
  • Commission: must improve impact assessments, engage earlier with national parliaments, and consider subsidiarity more rigorously.
  • CJEU: urged to enforce subsidiarity more robustly and consider Member State particularities.

Figures and deadlines

  • EUR 800 billion for the ReArm Europe Plan/Readiness 2030 instrument.
  • Eight-week deadline for national parliaments to submit reasoned opinions; proposed extension to 12 weeks.
  • Period between 20 December and 10 January excluded from deadlines.
