Impact of CoR opinions on EU legislation
What is the impact of CoR opinions on EU legislation and how is it measured? What follow-up does the CoR give to its opinions and resolutions, and how does it measure success ?  Increasing the CoR's political impact means increasing the influence of regions and local authorities in Europe.

Lisbon Treaty: a new role for the CoR

The Lisbon Treaty has strengthened the role of the CoR. It must be consulted during all phases of the EU legislative process and can bring EU legislation before the Court of Justice whenever it deems that its institutional rights or the principle of subsidiarity have been neglected. Consequently, the Committee's relations with the European Commission, the European Parliament and the Council have been intensified.


Impact measurement: a combination of time and reporting tools

The impact of many opinions can only be measured in the years following their adoption, once the legislative process has sufficiently advanced.
During this time, impact reports are established using the following resources:
  • Reports from the European Commission on the Commission's follow-up to CoR's opinions
  • CoR impact assessment sheets summarizing the political impact of the opinions on documents of the European Commission, the European Parliament and the Council
  • Media impact monitoring of opinions by the CoR press office
  • An average of 150 opinion related events  organised by the CoR contribute to enhance the impact of the CoR opinions and resolutions in the EU legislative process.
