European Union – Rules on competition. The Court of Justice of the European Union dismissed the appeal by Hansa Metallwerke AG (Hansa) and other companies against the decision of the General Court of the European Union in Hansa Metallwerke AG and others v European Commission: T-375/10, by which that court had dismissed the action by Hansa and the other companies for annulment of Commission Decision C(2010) in which the European Commission had found that those companies had infringed EU competition rules under art 101 of the Treaty on the Functioning of the European Union and art 53 of the Agreement on the European Economic Area in so far as that decision related to them, or, in the alternative, to reduce the amount of the fine imposed on them in that decision.
