1. Content of the on-line material provided

The ILP does not guarantee for the topicality, accuracy, completeness or quality of the provided material. Claims to liability against the ILP related to damages either material or non-material, through the use or non-use of the provided information or due to the use of incorrect or incomplete material are explicitly ruled out in so far that there is no evidence of intentional or gross negligence on the part of the ILP. All material provided is non-binding and without obligation. The ILP distinctly retains the right to modify, delete or publish parts of or the entire material provided at intervals or for good without prior notice.

2. Referral and Linking

In the case of direct or indirect referral to external pages (links) which lie outside the field of responsibility of the ILP (, the ILP can only be made liable if it were aware of the illegal content of the respective page and if it were technically feasible and reasonable to prohibit viewing of the pages. The ILP explicitly declares that at the time of linking the linked pages are free of all illegal content. The ILP has no influence on the up-dated and future design and content of the linked pages. Therefore, the ILP explicitly dissociates itself from any modified or altered content of the linked pages. This is valid for all links and referrals made to in the provided material as well as for external input to the guest book, discussion boards and mailing lists established by the ILP . For illegal, faulty or incomplete contents and especially for damages through the use or non-use of the available information the provider of the page referred to is alone liable and not the supplier providing the link.

The proprietary rights for published copyrighted material remains in the possession of the copyright holder (ILP or a third party). A reproduction or use of these graphics, recordings, video sequences or texts in further electronic or printed publications is not permitted without the explicit consent of the copyright holder even if not labelled as a copyright protected document. All labels and trademarks, including those possibly copyrighted by a third party mentioned within the provided material are subject without exception to the conditions of the respectively valid trademarks and ownership rights of the respective registered owner. It cannot be concluded on the basis of the mere naming that trademarks are not protected by a third party.
