The EU has struggled lately to respond when member states violate the bloc's fundamental values, especially the rule of law. A new policy brief from the Centre for European Reform says there is growing support for the rule of law to be included as a condition for EU funding. The paper points out that financial levers are the EU's most important, and it could respond to misbehaving states by taking a broader interpretation of existing EU laws, or proposing new conditions when the rules governing structural and investment funds are revised ahead of the next budget cycle.
