"If Joran van der Sloot is convicted, he will have to serve his term in Peru, Professor Knoops says. There is no judicial treaty between Peru and the Netherlands which would allow the sentence to be served in a Dutch jail. An ad hoc transfer of the verdict to the Dutch legal system would be possible only after Joran had exhausted all appeal options in Peru. "That could take quite a long time," according to the International Law professor."
