Ireland’s President Mary McAleese recently signed into law the Communications (Retention of Data) Act 2009, which implements the EU Data Retention Directive (EEC/24/06). The law requires providers of fixed line and mobile telephone services or Internet communications services to retain data on certain types of communications. The law specifically does not apply to the “content of communications." The Irish legislation goes beyond the minimum 6-month retention period mandated by the EU Directive by requiring that fixed line and mobile telephone providers save call data for two years, and Internet communications service providers retain traffic data for one year. Our readers will recall that Ireland had challenged the legality of the Data Retention Directive, but that challenge was rejected by the European Court of Justice two years ago. With enactment of this new law, Ireland is now fully on board the data retention train.
