This very complicated and high-profile case involved international conventions and contract law in the context of a large insurance claim. Following a serious and high-profile fatal train crash, a series of cases arose around the insurance liabilities of the train operators. The accident happened in one country, but was deemed to have been the fault of employees of the train company of another country. There is a convention in such cases that when a train accident happens, the (insurance company of the) train operator in the country in which the accident takes place takes responsibility for the resulting costs. In this case, the operator in the country where the accident took place argued that it was not a convention, but a contract and that the clear fault of the employees of the other country caused the contract to be overruled.
