Since 2003, the Belgian Court of Arbitration, which is known now as the Constitutional Court, can examine whether laws, decrees or ordinances are in compliance with Title II and with Articles 170, 172 and 191 (on the equality of Belgians and foreigners and the prohibition of tax discrimination) of the Constitution. When interpreting the rights enumerated in Title II of the Constitution, the Constitutional Court also applies the European Convention on Human Rights in order to prevent different interpretations of the same principles.
