Normative justifications of EU criminal law : European public goods and transnational interests

EU policy-making in criminal law is a matter of significant public concern for EU citizens and the Member States. The exercise of EU public powers in the fields of criminal law and law enforcement have tangible and adverse consequences for the liberties and well-being of individuals.
