part in its judgment of 31 January 2013. Breyer and the Federal Republic of Germany filed an appeal against the decision. On 19 October 2016, the European Court of Justice ruled on the basis of a submission by the Federal Court of Justice that dynamically assigned IP addresses represent personal data for the operator of a website if they can be traced to the subscriber in the course of criminal proceedings.
