European court rules that ISPs can't filter web content

Although it is not known how the ruling will affect the UK, the ECJ said about the verdict: "EU law precludes an injunction made against an internet service provider requiring it to install a system for filtering all electronic communications passing via its services which applies uninterruptedly to all its clients, as a preventive measure, exclusively at its expense and for an unlimited period."

"Such an injunction could potentially undermine freedom of information since that system might not distinguish adequately between unlawful content and lawful content with the result that its introduction could lead to the blocking of lawful communications."
