Does the CRA set fines directly or leave penalties to Member States?
Both. Article 64 requires Member States to lay down penalty rules and take the measures needed to implement them. Those penalties must be effective, proportionate, and dissuasive.
At the same time, Article 64 sets the main administrative-fine ceilings. Member States therefore design the national enforcement system, but they do so within the CRA's EU-level maximum fine structure.
Article 64(1) requires national penalty rules and Article 64(2) to (4) sets the main administrative-fine ceilings.
