A Spanish colleague sent me this “net neutrality” definition from a Spanish law:
Citizens have the right to not suffer in their digital sent or received data any kind of manipulation, distortion, prevention, diversion, priorization or delay. The exercise of this right must be independent from the source or target of the communication, from the protocol or application used, from the type of data content, or from any other consideration external to the wish of the citizen. This data traffic will be treated as a private communication and it will only be possible to spy, trace or analyse its content under a judicial order (exactly like in the case of any other current private mail).
