Whether a treaty or federal statute affirmatively authorized the Suquamish Tribe to exercise criminal jurisdiction over non-Indians.
Holding
No. Neither the Treaty of Point Elliott nor the federal statutes invoked by the Tribe authorized or confirmed tribal criminal jurisdiction over non-Indians.
Reasoning
The Tribe did not identify any treaty provision or Act of Congress expressly granting it criminal authority over non-Indians. The Indian Reorganization Act allowed tribes to organize and adopt governing documents, but it did not enlarge the powers tribes possessed under existing law. Likewise, the Indian Civil Rights Act supplied specified procedural protections to persons subject to tribal authority; it did not create or confirm criminal jurisdiction over non-Indians.
The Treaty of Point Elliott was not explicit on this question, but its historical setting pointed away from tribal authority. By acknowledging dependence on the United States and agreeing to deliver offenders against federal law to federal authorities, the Suquamish recognized the federal government's protective and criminal-law role with respect to non-Indian intruders. Those provisions alone might not have eliminated otherwise existing power, but they did not supply an affirmative grant of it.
Congress's longstanding treatment of criminal jurisdiction in Indian country reflected the same understanding. Federal law extended federal criminal jurisdiction to non-Indian offenses in Indian country, while preserving tribal authority in matters involving Indians. Congress repeatedly legislated on reservation criminal jurisdiction without providing a parallel rule allowing tribes to prosecute non-Indians, and historical statements by Congress, Executive officials, and lower courts consistently treated non-Indians as outside tribal criminal jurisdiction.
