Last year, the Supreme Court heard arguments, and requested extensive supplemental briefing, in Royal v. Murphy (now called Sharp v. Murphy) a complicated murder case involving federal Indian law. The Court was unable to decide the case last year and so it remains on the docket this year and for that reason alone seems poised to be complicated and quite intricate.
My colleague Todd Henderson teaches Indian Law here at Chicago and we've repeatedly discussed this case, so I wanted to pass along his thoughts about this case, and the problem that the Supreme Court's precedents in this area have created for itself.
Is half of Oklahoma—home to nearly 2 million people, many in the city of Tulsa—an Indian reservation?
