The European Commission has decided to reject a request from Austria to introduce national measures banning the use of genetically modified organisms in the region of Upper Austria for a three-year period. The request was made in March 2003, under Article 95(5) of the EC Treaty, which allows Member States to derogate from European Union harmonisation measures, under certain strict conditions. These include the emergence of new scientific evidence as well as the existence of particular country-specific conditions.
