Furthermore, while the interests of public security could justify the measure, the system for collecting and accessing the data is not sufficiently circumscribed to ensure that the interference with personal rights is limited to what is strictly necessary. In particular, the directive does not differentiate who is affected by the data collection or allow for exceptions, it does not set the terms for access to the collected data or in what circumstances it may be used, and it does not provide enough protection against possible abuse or unlawful access to the data. In addition, it does not require the data to be stored in the EU, meaning the data cannot be sufficiently protected.
The case against the directive was brought to the EU Court by the Irish group Digital Rights as well as several public and private parties in Austria. The court's advocate general issued an initial opinion in December 2013 that the directive violated individual rights. As a result of the court's final ruling, the directive is invalid rectro-actively from the date it entered into force.
