Relationship between the European Court of Justice and European Court of Human Rights
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.
Position of the European Union
The European Union (EU) has decided not to be bound by the rulings of the European Court of Human Rights.
The European Court of Justice (ECJ) gives the European Convention on Human Rights "special significance" as a "guiding principle" in its case law. The European Court of Justice uses a set of general principles of law to guide its decision-making process. One such principle is respect for fundamental rights, seen in Article 6(2) of the Treaty Establishing the European Union (Maastricht Treaty): "The Union shall respect fundamental rights, as guaranteed by the European Convention for the Protection of Human Rights and Fundamental Freedoms signed in Rome on 4 November 1950 and as they result from the constitutional traditions common to the Member States, as general principles of Community law." Within this framework, the European Court of Justice uses all treaties that the Member States of the European Union have signed or participated in as interpretive tools for the content and scope of "fundamental rights", while holding the European Convention on Human Rights as a document with "special significance."
As seen in Article 6(2) of the Maastricht Treaty, quoted above, the European Union is bound to respect fundamental rights principles. This means that the institutions of the European Union must not violate human rights, as defined by European Union law, and also that the Member States of the European Union must not violate European Union human rights principles when they implement Union legislation or act pursuant to Union law. This obligation is in addition to the Member States' pre-existing obligations to follow the rulings of the European Court of Human Rights in everything they do.
In practice, this means that the Court of Justice weaves the Convention principles throughout its reasoning. For example, in the Baumbast case, the Court held that when a child has a right of residence in a Member State according to Union law, this also means that his parent(s) should also have a right of residence due to the principle of respect for family life enshrined in Article 8 of the European Convention on Human Rights.
Position of the European Court of Human Rights
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 cases 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.
EU accession to ECHR
Protocol No. 14 of the ECHR entered into force on 1 June 2010. It allows the European Union to accede to the European Convention on Human Rights.
The EU's Treaty of Lisbon, in force since 1 December 2009, requires the EU to accede to the convention in Article 6 of the consolidated Treaty on European Union: "The Union shall accede to the European Convention for the Protection of Human Rights and Fundamental Freedoms. Such accession shall not affect the Union's competences as defined in the Treaties." The EU would thus be subject to its human rights law and external monitoring as its member states currently are. It is further proposed that the EU join as a member of the Council of Europe now that it has attained a single legal personality in the Lisbon Treaty.
On 5 April 2013, negotiators from the European Union and the Council of Europe finalised a draft agreement for the accession of the EU to the European Convention on Human Rights. As next steps, it is required that the European Court of Justice provides an opinion, subsequently that the EU member states provide unanimous support, that the European Parliament provides two-thirds majority support, and that the agreement is ratified by the parliaments of the Council of Europe's member states.
On 18 December 2014, the Court of Justice issued a negative opinion on the European Union's accession to the ECHR as it would give an external body the power to review the application of EU law, thus bringing the accession to a halt. After this deadlock, some Italian senators have put forward a new proposal, based on the partial merger of the two Courts.
