Liability: Austropa Interconvention acts as agent only and cannot be held responsible for any loss, injury or damage to any person or property whatever the cause may be. The liability of persons or enterprises providing means of transportation or other services, however, remains unaffected. Austropa Interconvention cannot be held liable for the partial or entire cancellation or the change of date of the congress. In the event of cancellation or change of date of the congress by the congress organiser, Austropa Interconvention shall not be held liable for any costs incurred or disadvantages suffered, including consequential losses, resulting from the cancellation or change of date. “Force majeure” shall free both parties from their contractual obligations arising out of this Agreement. The following events are deemed to be force majeure: war, occupation, riot, strike, complete collapse of the public utilities, complete suspension of air traffic (except for reasons of weather conditions or strike), but only if the hotel and its operation are directly concerned by these events. In the event of cancellation or change of date of the congress, as well as in the event of force majeure, all prior expenses incurred, in particular processing expenses, shall be charged to the company/contractor. The accommodation provider may provide the guests with adequate substitute accommodation (of the same quality) provided that this is reasonable for the guests, particularly if the difference is insignificant and objectively justified. An objective justification shall, for example, be deemed given if the rooms have become unusable, guests that have already been accommodated prolong their stay, the establishment is overbooked or this becomes necessary due to other important operational activities. Any extra expenses arising from such substitute accommodation shall be paid by the hotel. For all disputes arising out of this agreement, both parties to the agreement explicitly submit to the court having subject matter jurisdiction. Vienna shall be the exclusive venue for all disputes out of this Agreement. The laws of Austria shall apply.
