Prior to the entry into force on 1 June 2010 of Protocol No. 14 to the Convention for the Protection of Human Rights and Fundamental Freedoms, the EU could not accede to the Convention, and the European Court of Human Rights did not have jurisdiction to rule on case brought against the EU. However, the ECHR has been prepared to hold EU member states liable for human rights' violations committed within their jurisdictions, even when they were just complying with a mandatory provision of EU law.
