The Interpretaton of the Charter of Fundamental Rights of the EU in Data Retention Cases: national implementation and possible changes of policy

Tomáš Ochodek

announced: 04. 01. 2019


The Court of Justice of the EU has, on several occasions, ruled on the compatibility of so-called data retention measures with the Charter of Fundamental Rights of the EU. In particular, it has ruled that general and indiscriminate retention of certain electronic communications data is incompatible with Articles 7 and 8 of the Charter, be it in the form of EU secondary law or national legislation. Many Member States, however, still keep in place data retention measures contrary to these rulings, and progress in implementing the rulings is slow. At the same time, the rulings of the Court of Justice can also be interpreted as requiring a fundamental change in how these measures are used and how effective they can be.
