For crimes committed on Indian country with non-Indian offenders and victims, which entity has exclusive jurisdiction?

In cases involving crimes committed on Indian country between non-Indian offenders and victims, the correct entity with exclusive jurisdiction is indeed the Federal Government. This is due to the legal framework established by the Major Crimes Act and subsequent federal statutes that grant federal authorities jurisdiction over certain crimes occurring within Indian country, particularly when neither party is a tribal member.

Federal jurisdiction is necessary because Indian country is considered to have its own unique legal status; the tribes hold sovereignty, but when it comes to non-Indians committing crimes, federal law takes precedence to ensure a uniform application of justice in cases that do not involve tribal members.

This is crucial for maintaining order and justice in areas where tribal sovereignty and federal authority intersect, particularly when neither party has tribal affiliation. Understanding the delineation of jurisdiction in these cases is essential for law enforcement and legal professionals operating in or around Indian country.
