In the first criminal piracy decision by a United States court in nearly a century, the U.S. Court of Appeals for the Fourth Circuit ruled that the federal piracy statute’s reference to the “law of nations” explicitly ties the scope of the offense to evolving customary international law definitions of the crime. The court went on to find that under current customary and treaty law, attempted piracy falls within the scope of the international crime. In doing so, it joined several courts in nations around the world that have confronted the issue as a result of the outbreak of Somali piracy that began in 2008.
