The Court of Justice of the European Union (CJEU) is not institutionally related to the European Court of Human Rights: the two courts are related to distinct organizations. However, since all EU states are members of the Council of Europe and so are parties of the Convention on Human Rights, there are concerns about consistency in case law between the two courts. The CJEU refers to the case law of the European Court of Human Rights and treats the Convention on Human Rights as if it were part of the EU's legal system since it forms part of the legal principles of the EU member states.
