International Criminal Law in Swedish Courts : The Principle of Legality in the Arklöv Case

The district court of Stockholm convicted on 18 December 2006 Jackie Arklöv for a crime against international law. It was the first and, until the present date, the only time liability for an international crime has been tried before a Swedish court. This comment presents the law applied by the Court, draws attention to the principles of legality, ne bis in idem, and discusses whether a national court in a dualistic legal system can impose criminal responsibility with reference to customary international law
