yes and no. I can see this to fail in both the European Court of Justice and in the European Court of Human Rights (for non Europeans: the first is the EU "supreme court", the other is continent wide, voluntary and treaty based.) However it will take maybe 5 but more likely 10 years before a resolution comes out of those. In my country (the Netherlands) treaties take precedence above national law, and our constitution is just a piece of paper (no constitutional court, laws can't be checked by courts against the constitution). Add to that that we always want to be the teachers favorite pupil so we will enforce ACTA for many years.
