From the official press release[1]:
"The Court finds that, in adopting the injunction requiring Scarlet to install such a filtering system, the national court would not be respecting the requirement that a fair balance be struck between the right to intellectual property, on the one hand, and the freedom to conduct business, the right to protection of personal data and the right to receive or impart information, on the other."
I understand this isn't exactly revolutionary but amidst ACTA, SOPA, bailouts, and similar lunacy, this is a breath of fresh air and a glimmer of hope.
