By law, communications data in Austria have had to be saved for six months since 1 Apr 2012. The EU rule was passed in 2006. The Irish High Court asked the European Court of Justice to examine the rule in mid-July 2012, and it may happen in 2013.
Update on 12 Dec 2013: The European Court of Justice is examining the E.U. guideline requiring telecommunications companies to save customers’ data for “up to two years” in case they are suspected of committing crimes in the future.

ARD tagesschau.de moderator Jan Hofer said the court usually follows such expert opinions.
