Artists' resale right schemes, often also called droit de suite, have been a part of the law of a number of European countries since the 1920s. However, the disparity between those national systems that did recognize a resale right and the lack of a resale right in other member states prompted the European Commission to adopt harmonizing measures in the form of EU Directive 2001/84/EC on the resale rights of authors of original works of art. The object of the Directive is to confer the same benefits on authors/creators of graphic or plastic art, such as pictures, collages, paintings, sculptures and engravings, as other creators of artistic works who benefit from successive exploitations of their works. The Directive was passed on September 27 2001 and member states had until January 1 2006 to transpose it into domestic law.
