The Eleventh Amendment’s sovereign immunity doctrine bars private individuals from suing a state or a state agency in federal court for damages, and the Supreme Court has extended that protection to federal-law suits filed in state court as well. The rule reaches further than the amendment’s text: it covers suits by a state’s own residents, by other states’ residents, by foreign citizens, and by Indian tribes. It does not cover suits against cities and counties, suits against state officials in their personal capacity, suits for forward-looking injunctions against officials, suits brought by the United States itself, or bankruptcy proceedings. Whether you can sue a state usually turns on which of those categories your claim falls into.
What the Rule Actually Blocks
The amendment’s text withdraws federal judicial power over suits against a state by citizens of another state or by foreign citizens.1Congress.gov. U.S. Constitution – Eleventh Amendment But the Supreme Court has read the amendment as a confirmation of a broader sovereign immunity principle, not a narrow fix. In Hans v. Louisiana, the Court held that a state’s own citizens also cannot sue it in federal court, closing the most obvious textual gap.2Justia U.S. Supreme Court Center. Hans v. Louisiana, 134 U.S. 1 (1890)
State court is not a workaround. In Alden v. Maine, a group of probation officers sued Maine in its own courts for violating federal overtime law. The Supreme Court held 5-4 that states keep sovereign immunity from private suits in state court too, and that Congress cannot use its ordinary legislative powers to strip it.3Justia U.S. Supreme Court Center. Alden v. Maine, 527 U.S. 706 (1999) For most federal-law claims against a state, the courthouse door is closed regardless of which courthouse you pick.
Who Counts as the State
Immunity extends to entities that function as part of the state government. The most reliable test is financial: if a judgment would be paid from the state treasury, the entity is treated as an arm of the state.4Congress.gov. Constitution Annotated – Amdt11.6.3 State agencies, state universities, and state law enforcement agencies typically qualify.
Cities, counties, and towns do not. The Supreme Court has consistently refused to extend Eleventh Amendment immunity to political subdivisions, treating them as separate legal entities. State-law immunity a municipality enjoys at home does not travel with it into federal court, and a state cannot confer that protection.5Justia. U.S. Constitution Annotated – Suits Against States That is a meaningful difference for a civil rights plaintiff: suing a county sheriff’s department for a constitutional violation is jurisdictionally straightforward in a way that suing a state police agency is not.
Entities created by interstate compacts fall in between. In Hess v. Port Authority Trans-Hudson Corporation, the Court held that a bi-state entity is presumed not to have immunity unless the compact clearly gives it that protection and Congress agrees. Because the Port Authority raised its own revenue and paid its own debts without either state on the hook, a judgment against it would not touch a state treasury, and immunity did not apply.6Justia. Hess v. Port Authority Trans-Hudson Corporation
Suing a State Official for an Injunction
The most common way around the amendment is Ex parte Young. Decided in 1909, it lets a plaintiff sue a state official in their official capacity for an injunction ordering them to stop violating federal law.7Justia. Ex parte Young, 209 U.S. 123 The theory is that an official enforcing an unconstitutional statute acts outside their lawful authority and cannot claim the state’s immunity as a shield.
The relief has to be prospective. A federal court can order an official to change a policy going forward but cannot order the state to pay for past harm. Edelman v. Jordan drew the line: a retroactive award paid from state funds is, in practical effect, damages against the state and is barred.8Justia. Edelman v. Jordan Courts look at where the money would actually come from. If it would be drawn from general state revenues, the claim is retroactive relief in disguise, no matter how it’s styled.
Suing a State Official Personally
Sovereign immunity protects the state, not the individual holding the office. Under 42 U.S.C. ยง 1983, a plaintiff can sue any person who deprives them of federal rights while acting under state authority, and any resulting damages come from the individual defendant rather than the state.9Office of the Law Revision Counsel. 42 U.S. Code 1983 – Civil Action for Deprivation of Rights
Capacity is what matters. An official-capacity suit treats the state as the real defendant and can only produce forward-looking relief under Ex parte Young. A personal-capacity suit targets the individual, and the state’s immunity does not shield them.4Congress.gov. Constitution Annotated – Amdt11.6.3 The Supreme Court confirmed in Hafer v. Melo that state officials can be held personally liable under Section 1983 for conduct performed in their governmental role.
A separate obstacle applies here: qualified immunity. An official can defeat a personal-capacity claim by showing their conduct did not violate clearly established law a reasonable person would have known. That defense belongs to the individual, not the state, and it lives alongside sovereign immunity rather than replacing it.
When Congress Can Strip a State’s Immunity
Congress has one reliable tool for authorizing private suits against states: Section 5 of the Fourteenth Amendment. In Fitzpatrick v. Bitzer, the Court held that the Fourteenth Amendment’s enforcement power overrides Eleventh Amendment immunity, which is how Title VII of the Civil Rights Act opened state employers to employment discrimination suits.10Congress.gov. Amdt11.6.2 Abrogation of State Sovereign Immunity
Article I powers do not work. In Seminole Tribe of Florida v. Florida, the Court ruled that Congress cannot use the Commerce Clause or other Article I authorities to abrogate sovereign immunity, even when its regulatory power over the subject is exclusive.11Legal Information Institute. Seminole Tribe of Florida v. Florida
Section 5 itself has conditions. The statute must contain unmistakably clear language of abrogation, and Congress must have compiled evidence of a pattern of state constitutional violations that justifies the intrusion. In Board of Trustees of the University of Alabama v. Garrett, the Court struck down the abrogation in Title I of the Americans with Disabilities Act because Congress had not documented a sufficient pattern of unconstitutional disability discrimination by state employers.12Legal Information Institute. Board of Trustees of University of Alabama v. Garrett State employees lost the ability to sue their state employers for damages under that provision.
When a State Consents
A state can waive its immunity, but only clearly. In Atascadero State Hospital v. Scanlon, the Court held that a broad state-law waiver is not enough on its own. The waiver must specifically address suit in federal court.13Justia. Atascadero State Hosp. v. Scanlon, 473 U.S. 234 (1985) Generic “sue and be sued” language in a state statute typically falls short.14Congress.gov. Amdt11.6.1 Waiver of State Sovereign Immunity
A state can also consent by its conduct. If a state voluntarily removes a case from state court to federal court, it cannot then invoke immunity to escape the forum it chose. That was the holding in Lapides v. Board of Regents.15Legal Information Institute. Exceptions to Eleventh Amendment Immunity: Waiver
The Bankruptcy Exception
Federal bankruptcy proceedings sit outside the doctrine. In Central Virginia Community College v. Katz, the Court held that when the states ratified the Constitution, they agreed to subordinate their sovereign immunity in the bankruptcy system.16Justia. Central Va. Community College v. Katz, 546 U.S. 356 (2006) Unlike the Commerce Clause situation in Seminole Tribe, the Bankruptcy Clause carries a built-in surrender of immunity. A trustee can pursue a state agency to recover preferential transfers without running into an Eleventh Amendment defense.
Who Else Is Barred, and Who Is Not
The amendment’s protection runs against more plaintiffs than the text names. In Blatchford v. Native Village of Noatak, the Court held that Indian tribes cannot sue states in federal court without consent, reasoning that tribes were not parties to the constitutional convention and never mutually surrendered immunity with the states.17Legal Information Institute. Blatchford v. Native Village of Noatak, 501 U.S. 775 (1991) The federal statute giving district courts jurisdiction over tribal civil actions does not override immunity because it lacks the unmistakably clear language the Court requires. Foreign nations are barred as well: Principality of Monaco v. Mississippi held that a foreign country cannot sue a U.S. state without its consent.
The federal government is the one plaintiff that can. The United States is not a “citizen” under the amendment, and its authority to enforce federal law against states is treated as inherent in the constitutional structure. When the federal government sues, the Eleventh Amendment does not apply.
