In this case, the Supreme Court held that the Indian tribes cannot sue states under the Indian Gaming Regulatory Act in federal courts without state permission. In other words the tribes cannot force states to negotiate gaming compacts. The decision was based on the 11th Amendment to the constitution which provides that a state can only be sued in its own courts or if it consents to the suit. Basically, states have a sovereign immunity from lawsuits filed in federal courts and Congress cannot abridge that immunity through passage of the Indian Gaming Regulatory Act.
