In April 2014, however, the CJEU struck down the Data Retention Directive. PTS, Sweden's telecommunications regulator, told Swedish ISPs and telcos that they would no longer have to retain call records and internet metadata.[37] But after two government investigations found that Sweden's data retention law did not break its obligations to the European Convention on Human Rights, the PTS reversed course.[38] Most of Sweden's major telecommunications companies complied immediately, though Tele2 lodged an unsuccessful appeal.
