## Facts

- Gilbert P. Hyatt earned substantial patent-related income and claimed he changed domicile from California to Nevada in 1991.
- The California Franchise Tax Board (FTB) concluded Hyatt remained a California resident until April 1992 and assessed over \$10 million in back taxes, interest, and penalties.
- During the audit, FTB personnel conducted investigative activities in Nevada; Hyatt alleged intentional torts and bad-faith conduct, including harassment and improper disclosure of personal information.
- In 1998, Hyatt sued the FTB in Nevada state court seeking tort damages arising from the audit.
- Prior Supreme Court decisions in the same dispute addressed: (1) whether Nevada had to apply California’s statutory immunity (it did not), and (2) whether Nevada could impose greater damages liability on California than Nevada would face under similar Nevada-law limits (it could not).
- After remand from the second decision, the case returned to the Supreme Court on whether to overrule precedent permitting one state to be sued in another state’s courts without consent.

## Issues

1. Whether the Constitution permits a state to be sued by a private party, without the state’s consent, in the courts of another state.
2. Whether precedent allowing such suits (Nevada v. Hall) should be overruled.

## Decision

- The Court reversed the Nevada Supreme Court and remanded.
- The Court held that states retain sovereign immunity from private suits brought in other states’ courts absent consent.
- The Court overruled Nevada v. Hall, which had allowed such suits.
- A four-Justice dissent would have retained Hall based on stare decisis and disagreement with the majority’s historical and structural analysis.

## Legal Principles

- State sovereign immunity is a constitutional principle rooted in the federal structure; states did not surrender immunity to private suits in other states’ courts in the “plan of the Convention.”
- A state may not, without the defendant state’s consent, exercise jurisdiction over that state in a private damages action in its own courts.
- Stare decisis does not require retention of a precedent deemed inconsistent with constitutional structure and history where reliance interests are limited and subsequent practice shows minimal dependence on the rule.
- Full Faith and Credit constraints on discriminatory treatment of sister states do not substitute for a categorical immunity rule where the Constitution is understood to preserve inter-state sovereign immunity.

## Conclusion

The Court held that the Constitution bars private suits against a nonconsenting state in another state’s courts and overruled Nevada v. Hall, eliminating that forum for plaintiffs seeking damages from sister states.
