Exemption from liability

On 12 May 1998 the provincial court in Hamburg ruled that provision of a link meant taking joint responsibility for the content of the linked pages.  This can – according to the Hamburg provincial court – only be prevented, by expressly distancing yourself from these contents.  The following therefore applies to all links on this website and its sub-pages: It is expressly stated that the company FDM Service GmbH has no influence on the layout and the contents of the linked pages.  We therefore expressly distance ourselves herewith from all content on all linked pages on this website.
