European Union law

European Union law is a set of treaties and laws, such as regulations and directives, which have direct effect or indirect effect on the laws of the member states of the European Union. The three sources of European Union law are primary law, secondary law and supplementary law. The main sources of primary law are the Treaties establishing the European Union. Secondary sources include regulations and directives based on the Treaties. The European Union legislature is composed mainly by the European Parliament and the Council of the European Union, which under the Treaties can set the secondary law to the objective set out in the Treaties.
European Union law is applied by the courts of the Member States and the European Court of Justice. Where the law of the Member States provide fewer rights European Union law can be applied by the courts of the Member States. In case of European Union law, which should have been transposed to the legislation of the Member States, such as Directives, the European Commission may appeal against the Member State under the Treaty on the Functioning of the European Union. The European Court of Justice (part of the European Court of Justice is the highest court capable of interpreting the European Union law. Additional Sources of European Union law include the Court of Justice, international law and the general principles of EU law.
