The genetically modified maize line 1507 was approved for feed and industrial uses under EU-directive 2001/18/EC by Commission decision 8 August 2005. No authorisation is required in Norway for the deliberate release of genetically modified organisms (GMOs) that have been authorised in another EEA state in accordance with the EU’s GMO Directive (2001/18/EC). The use of such GMOs is also authorised in Norway unless a national decision to prohibit them is made under the Gene Technology Act. The Norwegian authorities may prohibit or restrict placing on the market if in their view it involves a risk to health or the environment, or if placing on the market is otherwise in conflict with the purpose of the Gene Technology Act, provided that their decision is otherwise in accordance with the EEA Agreement, see section 10, sixth paragraph, of the Gene Technology Act and the adaptations set out in Annex XX, item 25 d, to the EEA Agreement. According to the objects clause of the Gene Technology Act, the purpose of the Act is to ensure that the use of genetically modified organisms takes place in an ethically justifiable and socially acceptable manner, in accordance with the principle of sustainable development and without adverse effects on health and the environment. In legal terms, all production and use of genetically modified organisms apart from contained use in closed laboratory facilities is considered to be deliberate release.

The prohibition of placing on the market as feed and for industrial uses is found in the regulations FOR-2000-12-15-1268, on the prohibition of marketing in Norway of specific genetically modified products.
