Petition of the day

The petition of the day is:

Issues: (1) Whether, as Justices Ginsburg and Thomas suggested last term, this court should conduct a “fresh examination” of the “separate sovereigns” exception to the double jeopardy clause, Puerto Rico v. Sanchez Valle (Ginsburg, J., concurring); and (2) whether, as this court has previously suggested, the “separate sovereigns” exception at least should be inapplicable when state and federal prosecutors have worked so closely together that they are “in essential fact” one entity, Bartkus v. Illinois.
