<P> The relationship between the European Court of Justice (ECJ) and European Court of Human Rights (ECtHR) is an issue in European Union law and human rights law . The ECJ rules on European Union (EU) law while the ECtHR rules on the European Convention on Human Rights (ECHR), which covers the 47 member states of the Council of Europe . Cases cannot be brought in the ECtHR against the European Union, but the Court has ruled that states cannot escape their human rights obligations by saying that they were implementing EU law . </P> <P> The European Union (EU) has decided not to be bound by the rulings of the European Court of Human Rights . </P>

What difference if any is there between the cjeu and the european court of human rights
