By publication in the Federal Law Gazette (Bundesgesetzblatt), the new German law on data retention has entered into force. The law provides that telecommunication providers must retain data such  as phone numbers, the time and place of communication (except for emails), and the IP addresses for either four or 10 weeks. Business associations had criticised the law, saying that companies would  be burdened by the requirements. Data protection authorities also suggested that the law did not meet the standards set by the European Court of Justice and the German Federal Constitutional Court and that it interfered with citizens’ fundamental rights.
