The European Union has written its first Directive in 1986. The last revision dates from 2010 (2010/63/EU). Based on this Directive, the Belgian government has written law texts. These were implemented and translated to practices by means of Royal Decrees. The most recent Royal Decree (KB 2013-05-29) was revised in 2017 in the Decree of the Flemish government (BVR 2017-02-17).
