Lewis v. Clarke
Does tribal sovereign immunity bar a lawsuit brought against a tribal employee in his individual capacity when the tribe has agreed to indemnify that employee for any damages?

The Supreme Court ruled in favor of the Lewises, holding unanimously (8–0, with Justice Gorsuch not participating) that tribal sovereign immunity does not bar suits against tribal employees sued in their individual capacity, even when the tribe has agreed to indemnify the employee. Justice Sonia Sotomayor wrote the majority opinion, which was joined by Chief Justice Roberts and Justices Kennedy, Breyer, Alito, and Kagan.
The Court's reasoning centered on a fundamental principle of sovereign immunity law: immunity protects the sovereign entity, not the individuals who work for it. When someone is sued in their individual capacity, the party seeking to invoke sovereign immunity bears the burden of demonstrating that the lawsuit is actually directed at the sovereign. The Court explained that the critical question is not where the money will ultimately come from, but rather who is being sued and what kind of relief is being sought.
Justice Sotomayor's opinion applied the well-established distinction between official-capacity suits and individual-capacity suits. In an official-capacity suit, the named individual is essentially a stand-in for the entity, and any judgment runs against the entity. In an individual-capacity suit, the judgment runs against the person. Clarke was sued individually — the Lewises wanted a judgment against Clarke personally. The fact that the tribe might later reimburse Clarke under its indemnification policy did not change the nature of the suit.
The Court emphasized that an indemnification agreement is simply a contractual promise between an employer and employee — it does not transform the employee into the sovereign. If indemnification could extend sovereign immunity, any entity with immunity could effectively immunize all of its workers from personal tort liability just by promising to cover their costs, a result the Court found inconsistent with the purpose and limits of sovereign immunity. The decision reversed the Connecticut Supreme Court and sent the case back for further proceedings consistent with this ruling.
Concurring Opinions
Justice Clarence Thomas, joined by Justice Ruth Bader Ginsburg, concurred in the judgment but wrote separately to express broader doubts about the foundations of tribal sovereign immunity. Thomas argued that the Court had never offered a satisfying justification for extending common-law sovereign immunity to Indian tribes and suggested the doctrine warranted reexamination in an appropriate future case, though he agreed with the result in this particular case.
Background & Facts
In October 2011, Brian Clarke was working as a limousine driver for the Mohegan Tribal Gaming Authority, which operates the Mohegan Sun casino in Uncasville, Connecticut. While driving a limousine on Interstate 95 in Connecticut, Clarke rear-ended a vehicle occupied by William and Michelle Lewis. Both of the Lewises suffered injuries in the crash.
The Lewises filed a personal injury lawsuit against Clarke in Connecticut state court, suing him individually for negligence. They did not sue the Mohegan Tribe or the Mohegan Tribal Gaming Authority — they sued Clarke personally, as the driver who caused the accident. Clarke, however, moved to dismiss the case, arguing that because he was acting within the scope of his employment at the time of the crash, he was shielded by the sovereign immunity of the Mohegan Tribe. Critically, the tribe had an agreement to indemnify its employees — meaning the tribe had promised to cover any judgment or settlement costs arising from incidents occurring during the course of employment.
The Connecticut trial court agreed with Clarke and dismissed the lawsuit. The Connecticut Appellate Court affirmed that dismissal, and the Connecticut Supreme Court also ruled in Clarke's favor. The state high court reasoned that because the Mohegan Tribe would ultimately bear the financial cost of any judgment through its indemnification agreement, the suit was effectively one against the tribe itself, and therefore tribal sovereign immunity applied.
The Lewises petitioned the U.S. Supreme Court for review. The Court agreed to hear the case because lower courts across the country had reached conflicting conclusions about whether tribal sovereign immunity extends to individual tribal employees sued in their personal capacity — particularly when the tribe has agreed to indemnify them. This split of authority made the question ripe for a definitive national ruling.
The Arguments
The Lewises argued that their lawsuit was against Brian Clarke as an individual, not against the Mohegan Tribe, and that sovereign immunity protects only the sovereign entity itself — not individual employees sued in their personal capacity. They contended that the tribe's indemnification agreement should not transform an individual-capacity suit into a suit against the tribe.
- Sovereign immunity has always been understood to protect the sovereign entity from suit, not to shield individual people from personal liability for their own tortious conduct.
- The mere fact that an employer agrees to pay for an employee's legal liabilities does not change who is being sued — Clarke, not the tribe, was the named defendant.
- If indemnification agreements could extend sovereign immunity to individuals, it would create an enormous loophole allowing tribes (or states) to immunize any person from suit simply by promising to cover their costs.
Clarke argued that because he was acting within the scope of his tribal employment at the time of the accident, and because the tribe had agreed to indemnify him, the real party in interest was the tribe itself. Therefore, the suit was functionally against the tribe and barred by sovereign immunity.
- Because the tribe's indemnification agreement meant any judgment would ultimately be paid from tribal funds, the lawsuit was effectively one against the tribe and its treasury.
- Allowing individual-capacity suits against tribal employees for on-the-job conduct would effectively gut tribal sovereign immunity by giving plaintiffs an easy workaround.
- Courts should look at the substance and practical effect of a lawsuit, not just the caption, and here the real target was tribal resources.
