An appeals court in Sweden has overturned a landmark anti-piracy ruling that forced an internet service provider to identify a subscriber to five publishers.
In June, a lower court issued the order under a Swedish anti-piracy law introduced in April that enables copyright holders to ask ISPs to identify users suspected of illegal file sharing.
The law was passed in line with the European Union's Intellectual Property Rights Enforcement Directive (IPRED).
The five publishers had sued Sweden's Ephone ISP to obtain the IP address of a server containing 27 audio books to which they held the rights.
But the Stockholm court of appeals overturned the ruling because the publishers had not proved that the server was accessible to the public at large, reported the Telegraph.
Sweden's IPRED law, which has been praised by copyright holders in various industries, is believed to have reduced illegal downloading in the country by up to 40% in the past six months.
