Fifteen years after its proclamation, it is possible to make an impact assessment of EU Charter of fundamental rights in the European system (both in the EU and in every single member state) in order to evaluate its tragic failures and unfulfilled opportunities, in particular as an instrument enforcing the rule of law in social and immigration fields. The Charter provides a valuable instrument in specific areas for European law, above all in the protection of rights for Internet users and in traditional civil matters, but it has failed in defending the social rights affected by the austerity measures adopted in the framework of «rescue plans» and recommended in the EU economical governance. In social matters, the role of the Charter is modest or inexistent. The socio-economic rights have not been strengthened by the Charter, because they have been subordinated to the defense of the euro. The Court of Justice has played an ambiguous role, declaring it self incompetent to judge if the austerity measures are contrary to the Charter of Nice. Certainly if we want to save the Charter of Fundamental Rights from its trivialization we must start from its current judicial difficulties and think of a strong revival on the political-institutional level that values the Bill of Rights as orientation and policy text, in analogy with national constitutions. So there is still much to do to make concrete the idea of a supranational demos that can recognize in the leading value of its Charter of Rights and in its effectiveness, but the battle is not yet definitely lost.
