While the EU doesn't have a "constitution" per se, it does have several documents and treaties that serve a similar purpose. From the article: >one crucial question in the upcoming policy debate will be whether this latter measure, or its implementation, is compatible with the rights of privacy and data protection under the EU Charter of Fundamental Rights (the Charter). The Charter of Fundamental Rights serves as the EU Bill of Rights (the American version of which accounts for a huge portion of "constitutional" jurisprudence), and the Treaty of Lisbon makes that charter legally binding. Of note is that a previous iteration of said Treaty was explicitly called "Treaty establishing a Constitution for Europe" and was ratified by most of the member states.
