What it's about
The Court refused to hear the case (denied review) and did not decide those questions.
The petition raised questions about Fifth Amendment protections and Congress’s power to criminalize drug conduct at sea.
Question presented
1. Whether the prosecution of a foreign citizen on a foreign- registered boat for drug activity outside of and having no connection to the United States violates the Fifth Amendment’s Due Process Clause— a question that divides the Circuits? 2. Whether Congress’s authority “[t]o define and punish Piracies and Felonies committed on the high Seas,” U.S. Const. Art. I, § 8, cl. 10, permits it to criminalize drug conduct, having no connection to the United States, by a foreign citizen on a foreign-registered boat? 3. Whether Congress’s authority “[t]o define and punish Piracies and Felonies committed on the high Seas,” U.S. Const. Art. I, § 8, cl. 10, permits it to criminalize drug conduct committed within a foreign nation’s exclusive economic zone?
