Ministerio Fiscal: Holding the line on ePrivacy: Case C-207/16 Ministerio Fiscal, EU:C:2018:788.

In Ministerio Fiscal the Court of Justice of the European Union has considered once again the criteria governing access by the authorities to data retained by electronic communications service providers permitted under Article 15(1) of Directive 2002/58 (the ‘ePrivacy Directive’), in particular the principle of proportionality and the concept of ‘serious crime’ as developed in the recent Digital Rights and Tele2 rulings.
