April 9, 1O, and 11 the Fifteenth Telders International Law Moot Court Competition will take place. For this Anniversary twelve European countries will be sending teams to the Peace Palace in The Hague. The case put before the teams this year, entitled ‘the Case of the Expropriated Toxin Business’, combines topics of general international law such as arbitration and state responsibility with legal problems concerning transnational corporations. Furthermore, production of toxin materials, investment and expropriation are important aspects of the case. The case involves three countries and an international group of companies (a transnational corporation or TNC) which has been engaged in unlawful activities.
