External links
Cross references marked as ‘links’ to websites of third parties are always living (dynamic) referrals. When first referencing the hyperlink, the DWA carefully verifies the external contents for possible infringement of civil or criminal law. However, the DWA does not continually check these third party sites for possible modifications which could constitute new grounds for liability. Hence, the DWA cannot be held responsible for the contents of websites to which it makes reference. In case damages are caused by the use of such information, the author of the respective external website pages is likely to be liable, but not the DWA having merely referred to the website concerned. Whenever the DWA notices or is informed by third parties about any changes of content on any referenced or linked website that might infringe upon civil or criminal law, it will promptly remove the link in question.
