The Fourth Circuit Court of Appeals affirmed a Somali pirates' conviction for various federal offenses including piracy and violence against maritime navigation. The case is USA v. Shibin and the opinion can be found here.
This case arose out of several piracies off the Somali coast in 2010 and 2011. The defendant had various roles in the piracies, including negotiator and "regular" pirate.
The FBI, in conjunction with Somali "Host Nation Defense Forces", arrested Shibin in Somalia.
Among the issues on appeal are the argument that Shibin did not actually venture into the high seas, but was only charged with aiding and abetting piracies that occurred on the high seas and was not personally on the high seas. Interpreting the United Nations Convention on the Law of the Sea, the court found that the geographic element of piracy did not apply to those that are charged with facilitating piracy. Sl ong as the non-high seas conduct incited or facilitated acts committed on the high seas, the Article was violated.
Shibin also argued that he was forcibly removed from Somalia and had not opportunity to challenge his removal in Somalia, noting that there was no extradition treaty between Somalia and the United States. This argument has failed before in U.S. courts, under the Ker-Frisbie Doctrine, and it failed here.
Shibin also argued that the prosecution was based on statutes that could not apply extraterritorially. The court found constitutional authority for the extraterritorial crimes:
Congress’ power to enact statutes that extend extraterritorially is derived generally from the Define and Punish Clause, U.S. Const. art. I, § 8, cl. 10; the Treaty Power, U.S. Const. art. II, § 2, cl. 2; and the Necessary and Proper Clause, U.S. Const. art. I, § 8, cl. 18.
Thus far, there are no circuit splits, so it seems that piracy cases won't be making it to the Supreme Court any time soon.
