The Eleventh Amendment means that a private person generally cannot sue a state in federal court unless the state agrees to be sued or Congress has specifically authorized the suit under the Fourteenth Amendment. Ratified in 1795, it is the constitutional source of what courts now call state sovereign immunity. The text is narrow, but the doctrine built on it is broad, and that gap between what the amendment says and what it does is the whole story.
What the Text Says
The amendment is a single sentence: “The Judicial power of the United States shall not be construed to extend to any suit in law or equity, commenced or prosecuted against one of the United States by Citizens of another State, or by Citizens or Subjects of any Foreign State.”1LII / Legal Information Institute. Amendment XI – Suits Against States
Read literally, it blocks two groups from suing a state in federal court: citizens of a different state and citizens of a foreign country. That is all the words do. Everything else the amendment is understood to mean today comes from how the Supreme Court has interpreted it.
Why It Was Added
The amendment was a direct response to Chisholm v. Georgia (1793), where the Supreme Court ruled 4–1 that a South Carolina executor could sue Georgia in federal court over an unpaid Revolutionary War debt.2Federal Judicial Center. Chisholm v Georgia (1793) States reacted with alarm. Congress proposed a fix within a year, and ratification followed by 1795.3National Park Service. The Supreme Court Decides in Chisholm v Georgia The purpose was straightforward: stop private citizens from dragging states into federal court against their will.
How the Doctrine Grew Beyond the Words
The text says nothing about a state’s own residents suing it. The Supreme Court closed that gap in Hans v. Louisiana (1890), holding that a citizen cannot sue his own state in federal court without consent. Allowing in-staters to sue while blocking out-of-staters, the Court reasoned, would be absurd.4Justia U.S. Supreme Court Center. Hans v Louisiana
The expansion continued into state courts. In Alden v. Maine (1999), the Court held that states also keep sovereign immunity in their own courts against private suits based on federal law, and that Congress cannot use its ordinary legislative powers to strip that immunity away. The Court treated this as a structural principle built into the Constitution itself, rooted in the idea that states entered the union with their sovereignty intact.5LII / Cornell Law School. John H Alden, et al., Petitioners v Maine
So the working meaning of the Eleventh Amendment today is wider than its text. A private person generally cannot force a state into any court, state or federal, without the state’s permission or a specific constitutional exception.
Who Counts as “the State”
Sovereign immunity covers the state itself and entities that function as “arms of the state.” State universities usually qualify. Courts look at how state law defines the entity, how much control the state exercises, where the funding comes from, and whether a judgment would be paid out of the state treasury.1LII / Legal Information Institute. Amendment XI – Suits Against States
Cities, counties, and towns are not covered. The Supreme Court has consistently refused to extend Eleventh Amendment immunity to local governments, and states cannot confer it on them.1LII / Legal Information Institute. Amendment XI – Suits Against States Local school boards often fall outside the shield too, depending on how much fiscal independence they have from the state. If your dispute is with a city or county rather than the state itself, the Eleventh Amendment is not the obstacle.
When a State Can Still Be Sued
Three exceptions do most of the work.
The State Consents
A state can waive its immunity, but the waiver must be unmistakable. A statutory waiver counts “only where stated in the most express language or by such overwhelming implication from the text as [will] leave no room for any other reasonable construction.”6LII / Legal Information Institute. U.S. Constitution Annotated – Amendment XI – Waiver of State Sovereign Immunity A state that voluntarily removes a case to federal court cannot then claim immunity, but vague statutory language does not count as consent.
Congress Overrides Immunity Under the Fourteenth Amendment
Congress can strip state immunity when it acts under Section 5 of the Fourteenth Amendment, which lets Congress enforce due process and equal protection. In Fitzpatrick v. Bitzer (1976), the Supreme Court held that the Fourteenth Amendment “operated to alter the pre-existing balance between state and federal power” and let Congress authorize private suits against states to enforce civil rights.7LII / Legal Information Institute. Abrogation of State Sovereign Immunity That is why state employees can sue a state employer for workplace discrimination under Title VII.
Congress cannot use its ordinary Article I powers, like the commerce power, to override state immunity. The Court drew that line in Seminole Tribe v. Florida (1996).8Library of Congress. Fourteenth Amendment, Section 5 – Modern Doctrine on Enforcement Clause The consequences are concrete. When Congress tried to open states to copyright and patent suits using its intellectual property powers, the Court struck those laws down. After Allen v. Cooper (2020), states are generally immune from damages for copyright infringement, and after Florida Prepaid v. College Savings Bank, the same goes for patent infringement.
Suing a State Official Under Ex parte Young
The most useful exception in day-to-day litigation comes from Ex parte Young (1908). You cannot sue the state, but you can sue a state official in federal court to stop an ongoing violation of federal law. The legal fiction is that an official who acts unconstitutionally is “stripped of official character” and is no longer acting for the state, so the Eleventh Amendment does not apply.9Federal Judicial Center. Ex parte Young (1908) The limit is important: you can only get prospective relief, meaning a court order telling the official to stop the illegal conduct going forward. You generally cannot get money damages paid from the state treasury this way.
Money Damages Versus Court Orders
This is where the amendment bites hardest. In Edelman v. Jordan (1974), the Supreme Court held that a federal court could order a state official to comply with federal law going forward, but could not order the state to pay benefits it should have paid in the past. Retroactive money relief, even dressed up as equitable restitution and aimed at an official, was really a damages award against the state treasury, and the Eleventh Amendment barred it.
One workaround exists. Under 42 U.S.C. § 1983, you can sue a state official in their personal capacity for money damages for violating your constitutional rights. Because the judgment comes from the official’s own pocket rather than the state treasury, sovereign immunity does not apply. Qualified immunity is a separate hurdle: the official is protected unless the right they violated was “clearly established” at the time.
What the Amendment Does Not Reach
The Eleventh Amendment restricts only suits brought by private parties. The federal government can sue any state in federal court. One state can sue another state, and those disputes go directly to the Supreme Court under its original jurisdiction.1LII / Legal Information Institute. Amendment XI – Suits Against States
Bankruptcy and admiralty carve out further space. In bankruptcy, a discharge proceeding is treated as an action against the debt itself rather than against the state. The Supreme Court has held that exercising federal jurisdiction over property in a bankruptcy case is no more threatening to state sovereignty than doing so in admiralty, since both target the property, not the state.10Cornell Law School.

What It Means in Practice
State sovereign immunity sounds abstract until you are the person it blocks. A state employee denied overtime may find the Fair Labor Standards Act unenforceable against the state in federal court. A photographer whose work is copied by a state university likely cannot sue for damages. A person injured by a negligent state agency may have no federal remedy and must use the state’s own tort claims process, often with strict caps and short deadlines.
The amendment does not make states untouchable. It funnels you into specific channels. If a state is violating your constitutional rights, the usual route is a suit against the responsible official for an injunction under Ex parte Young, or a personal-capacity suit under § 1983 if you need damages. Where Congress has authorized suits against states through its Fourteenth Amendment enforcement power, as it did with Title VII, you can proceed directly. Outside those channels, a state can be sued only if it agrees to it.
