A court in The Hague ruled earlier this month that it is legal to break WiFi security to use the internet connection. The court also decided that piggybacking on open WiFi networks in bars and hotels can not be prosecuted. In many countries both actions are illegal and often can be fined. The ruling is linked to a case of a student who threatened to shoot down everyone at the Maerlant College in The Hague, a high school. He posted a threat on the internet message board 4chan.org using a WiFi connection that he broke into. The student was convicted for posting the message and sentenced to 20 hours of community service, but he was acquitted of the WiFi hacking charges.
The Judge reasoned that the student didn't gain access to the computer connected to the router, but only used the routers internet connection. Under Dutch law breaking in to a computer is forbidden. (more)
