歐盟法院 (The Court of Justice of the European Union) 認為公開無線網路的營運者不需要對使用者的侵權行為負責：「EU Court: Open WiFi Operator Not Liable For Pirate Users」。
不過這是有一些前提的，法院認為應該要符合這幾個要件，營運方才不要負責。基本上完全沒有 filter 限制的無線網路會符合這些條件：
The Court further notes that in order for such ‘mere conduit’ services to be exempt from third party liability, three cumulative conditions must be met:
– The provider must not have initiated the transmission
– It must not have selected the recipient of the transmission
– It must neither have selected nor modified the information contained in the transmission.
In an effort to strike a balance between protecting a service provider from third party liability and the rights of IP owners, the Court ruled that providers can be required to end infringement.
“[T]he directive does not preclude the copyright holder from seeking before a national authority or court to have such a service provider ordered to end, or prevent, any infringement of copyright committed by its customers,” the Court found.
One such measure could include the obtaining of an injunction which would force an operator to password-protect his open WiFi network in order to deter infringement.
On a more positive note, the Court rejected the notion of monitoring networks for infringement or taking more aggressive actions where unnecessary.
“[T]he directive expressly rules out the adoption of a measure to monitor information transmitted via a given network. Similarly, a measure consisting in terminating the internet connection completely without considering the adoption of measures less restrictive of the connection provider’s freedom to conduct a business would not be capable of reconciling the abovementioned conflicting rights,” the Court concludes.
