Non-Indians and Tribal Criminal Jurisdiction
According to current U.S. legal interpretations, non-Indian U.S. citizens are not subject to tribal criminal jurisdiction. A critical well-known case is where the U.S. Supreme Court ruled that the non-Indian defendant Mark Oliphant could not be prosecuted under tribal court jurisdiction. The tribal court assumed jurisdiction of Oliphant because his crimes were committed within the territorial limits of the reservation. Oliphant was charged with drunken disorderly conduct during an annual ceremonial gathering of the Suquamish Tribe.
