Union law consists of so-called primary and secondary law. The concept of primary law relates to law made by the Member States via their international law treaty-making powers. Therefore, it comprises the initial 1957 Treaty of Rome plus various treaty amendments, such as the SEA, the Maastricht, Amsterdam, Nice and Lisbon Treaties, the Charter of Fundamental Rights as well as the accession treaties. Secondary law, on the other hand, refers to law made by the Union’s institutions based on the authorisation contained in the Treaties (the primary law). Articles 288 to 292 TFEU outline the different categories of legal acts of the Union. Whereas Article 288 TFEU refers to the instruments to be used by the Union, Articles 289–292 TFEU establish a hierarchy of norms between legislative and non-legislative acts. Article 294 TFEU specifies the most important form of law-making, the ordinary legislative procedure, whereas various special legislative procedures are found throughout the Treaty.
