According to Spiegel online, the ruling made by the highest appeal court in the land, makes it harder for anti-piracy organisations to trace an infringing IP-address back to a customer. However the case was started by Holger Voss, a 33 year old man from Münster who was sued for making a sarcastic comment in an Internet forum back in 2002.
A district court and the regional court, now the federal appeal court decided that T-Online had no right to store the IP-logs without a legal reason. Under the ruling, ISPs will have to delete IP logs if the customer asks them to do so.
