Alarmed by the increase in piracy, the United Nations has proposed the establishment - for a transitional period - of a Somali extra-territorial jurisdiction court in the Tanzanian city of Arusha to deal just with piracy cases. Jack Lang, the Special Adviser on Legal Issues related to Piracy, told reporters the estimated costs of setting up a court would be around 25 million dollars. This, he pointed out, was 'a relatively modest expense compared to the estimated seven billion dollars' that is the current cost of piracy, including the multi-million-dollar ransoms extracted by pirates in the high seas.
