In October 2006, Köhler made a far-reaching decision by vetoing the bill which would transfer Germany's Air Safety Administration Deutsche Flugsicherung into private ownership. The Bundestag passed this legislation but as President, Köhler was authorized not to sign it into law if, in his opinion, it contravened the constitution. In December 2006 he did not sign the Consumer Information Law (which intended to make information collected by public food safety agencies available to consumers), because the constitution does not allow the federal government to instruct municipal authorities. This can only be done by the German states. There had only been six previous occasions when Germany's president had chosen to reject bills, in most instances less important legislation had been involved. His vetoes were the first notable examples in recent German history.
