In Hans v. Louisiana (1890), the Supreme Court held that a state cannot be sued in federal court by one of its own citizens without the state’s consent, even when the lawsuit claims the state violated the U.S. Constitution. The ruling read state sovereign immunity as a principle embedded in the constitutional structure itself, not confined to the narrow words of the Eleventh Amendment. More than a century later, it is still the case every sovereign immunity dispute traces back to.
The Bond Dispute Behind the Case
Bernard Hans, a Louisiana citizen, held state bonds issued under an 1874 legislative act and a matching state constitutional amendment. That amendment declared the bonds “a valid contract between the state and each and every holder.”1Justia. Hans v. Louisiana, 134 U.S. 1 (1890) The bonds carried coupons entitling holders to regular interest payments.
In 1879, Louisiana adopted a new constitution that walked away from the deal. It cancelled the coupons falling due in January 1880 and rerouted the tax revenue that had been dedicated to interest payments into general state expenses.2Legal Information Institute. Hans v. Louisiana
Hans sued the state in United States Circuit Court, arguing that the repudiation violated the Contracts Clause of the U.S. Constitution, which bars states from passing laws that impair the obligation of contracts. Because his claim arose under the Constitution, he believed federal court was the right forum. The circuit court dismissed the case, and he appealed.
The Textual Gap the Court Had to Fill
The case turned on a mismatch between two parts of the Constitution. Article III extends federal judicial power to “all cases, in law and equity, arising under this Constitution, the laws of the United States, and treaties.”3Legal Information Institute. Article III Hans’s Contracts Clause claim fit that description.
The Eleventh Amendment, ratified in 1795, provides that federal judicial power “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.”4National Archives. The Constitution: Amendments 11-27 Read literally, it only blocks suits by out-of-state or foreign citizens. Hans was a Louisianan suing Louisiana, so the amendment’s text did not reach him.
Could he proceed anyway? That was the question.
What the Supreme Court Held
The Court, in an opinion by Justice Bradley, said no. It framed the issue directly: whether “a state can be sued in a circuit court of the United States by one of its own citizens upon a suggestion that the case is one that arises under the constitution or laws of the United States.” The answer was no.1Justia. Hans v. Louisiana, 134 U.S. 1 (1890)
The reasoning reached past the Eleventh Amendment’s text. Bradley wrote that sovereign immunity was “inherent in the nature of sovereignty” and that the idea of suing a state without its consent “was a thing unknown to the law.” On this view, the Eleventh Amendment was not the source of state immunity but one expression of a broader principle woven into the constitutional design. Article III’s grant of federal judicial power was never meant to override the traditional immunity of sovereign states.2Legal Information Institute. Hans v. Louisiana
The Court read the history around Chisholm v. Georgia (1793), which had allowed a South Carolina citizen to sue Georgia and provoked the Eleventh Amendment in response,5Justia. Chisholm v. Georgia6Congress.gov. Early Amendments (Eleventh and Twelfth Amendments) as proof that Chisholm had been wrong from the start. The amendment, in the majority’s telling, restored an understanding that should have prevailed all along. If the framers never meant to allow suits by out-of-state citizens, they equally never meant to allow suits by a state’s own citizens.
Justice Harlan’s Separate View
Justice Harlan agreed with the outcome but broke with the reasoning. He concurred “upon this ground alone” that a suit against a state by its own citizen was not within federal judicial power, and he objected to the majority’s swipe at Chisholm, which he thought “was based upon a sound interpretation of the Constitution as that instrument then was.”1Justia. Hans v. Louisiana, 134 U.S. 1 (1890) The disagreement matters. Harlan saw the Eleventh Amendment as an actual change in the law; the majority saw it as a correction. That split is still the fault line in modern debate over whether Hans was rightly decided.
When a State Can Still Be Sued
Hans did not put states beyond the reach of federal law. It set the default, but the default has significant exceptions, and understanding them is what turns the case from history into a working doctrine.
Consent and Waiver
A state can lower the shield. But courts require a waiver to be unmistakable. A statutory waiver counts only when stated “in the most express language or by such overwhelming implication from the text as [will] leave no room for any other reasonable construction.”7Constitution Annotated. Waiver of State Sovereign Immunity
Several patterns look like waivers and are not. A general “sue and be sued” clause in a state charter is usually not enough. Broad language consenting to suits “of any form or nature” can be read as consenting only to suits in the state’s own courts. Accepting money under a federal spending program does not, by itself, count as consent.7Constitution Annotated. Waiver of State Sovereign Immunity Claims against states routinely collapse here because plaintiffs read a provision that looks broad and discover the courts read the same language narrowly.
Suing the Official Instead: Ex Parte Young
If a state law violates the Constitution but immunity blocks a direct suit against the state, someone still has to be able to enforce constitutional limits. The Court’s answer arrived in Ex parte Young (1908). A plaintiff may sue a state official in federal court to stop that official from enforcing an unconstitutional state law. An officer who enforces such a law “is in that case stripped of his official or representative character and is subjected in his person to the consequences of his individual conduct.”8Legal Information Institute. Ex Parte Young Because the officer is treated as acting on his own, the state’s immunity does not protect him.9Justia. Ex Parte Young, 209 U.S. 123 (1908)
The doctrine has a hard limit. It reaches forward-looking relief only. A court can order a state official to stop doing something unconstitutional, but it cannot award money damages that would effectively be paid by the state treasury. That is what keeps the fiction workable: the suit is against the officer, and the remedy cannot touch the state’s wallet.
Congress Overriding Immunity Under the Fourteenth Amendment
Congress has one well-established route to strip state immunity outright: Section 5 of the Fourteenth Amendment, which lets it “enforce, by appropriate legislation,” the amendment’s guarantees of due process and equal protection.10Congress.gov. Modern Doctrine on Enforcement Clause In Fitzpatrick v. Bitzer (1976), the Court held that when Congress acts under Section 5, it can authorize private lawsuits against states that “are constitutionally impermissible in other contexts,” because the Eleventh Amendment and sovereign immunity “are necessarily limited by the enforcement provisions of § 5.”11Justia. Fitzpatrick v. Bitzer, 427 U.S. 445 (1976) This is how federal civil rights statutes like Title VII allow employees to sue state agencies for discrimination.
The Article I Wall
Congress’s other legislative powers do not carry the same override. In Seminole Tribe of Florida v. Florida (1996), the Court held that “Article I cannot be used to circumvent the constitutional limitations placed upon federal jurisdiction,” striking down a law that had tried to authorize suits against states under the Indian Commerce Clause and overturning an earlier precedent that had allowed abrogation under the Interstate Commerce Clause.12Justia. Seminole Tribe of Florida v. Florida, 517 U.S. 44 (1996)
The Court reinforced the wall in Allen v. Cooper (2020), holding that Congress “lacked authority to abrogate the States’ immunity from copyright infringement suits” in the Copyright Remedy Clarification Act.13Justia. Allen v. Cooper, 589 U.S. ___ (2020) The practical result is stark. A state that infringes a copyright can, in many circumstances, avoid being sued for it.
Immunity in State Courts, Too
Plaintiffs blocked from federal court once tried the obvious workaround: file the same claim in state court, on the theory that the Eleventh Amendment only limits federal judicial power. Alden v. Maine (1999) closed that door. State probation officers had sued Maine in state court under the federal Fair Labor Standards Act. The Court held that “the States retain immunity from private suit in their own courts, an immunity beyond the congressional power to abrogate by Article I legislation.”14Justia. Alden v. Maine, 527 U.S. 706 (1999) Sovereign immunity, in other words, is not about which courthouse you pick. Many states have voluntarily waived immunity for certain claims in their own courts, but that is the state’s choice, not something Congress can force.
Structural Waivers: What the States Gave Up at the Founding
The Article I wall has a growing exception. For certain federal powers so central to the constitutional plan that the states are understood to have surrendered their immunity when they ratified, sovereign immunity does not apply. The Court calls these “structural waivers,” triggered when a federal power is “complete in itself, and the States consented to the exercise of that power—in its entirety—in the plan of the Convention.”15Justia. Torres v. Texas Department of Public Safety, 597 U.S. ___ (2022)
The clearest example is bankruptcy. In Central Virginia Community College v. Katz (2006), the Court held that the states agreed at the founding not to assert immunity in bankruptcy proceedings, concluding that the bankruptcy power “was understood to carry with it the power to subordinate state sovereignty, albeit within a limited sphere.”16Justia. Central Virginia Community College v. Katz, 546 U.S. 356 (2006) The Court extended the logic to federal eminent domain in PennEast Pipeline Co. v. New Jersey (2021),17Justia. PennEast Pipeline Co. v. New Jersey, 594 U.S. ___ (2021) and to the war powers in Torres v. Texas Department of Public Safety (2022), which allowed a suit under the Uniformed Services Employment and Reemployment Rights Act.15Justia. Torres v. Texas Department of Public Safety, 597 U.S. ___ (2022)
There is no fixed list of which Article I powers qualify. The line the Court is drawing is that certain federal powers were so essential to the constitutional bargain that immunity was surrendered as part of ratification itself.
Why Hans Still Runs the Doctrine
Hans converted the Eleventh Amendment from a narrow textual rule into the surface expression of a much wider constitutional principle. When Alden extended immunity into state courts, it leaned on Hans‘s premise that sovereign states cannot be hauled into court without agreeing to it. When Seminole Tribe blocked Congress from using Article I to override immunity, it cited Hans for the proposition that immunity is embedded in the structure of the Constitution.
The case has never lacked critics. Harlan’s 1890 concurrence identified the core tension that persists today. Justices who favor a narrower reading argue that Hans read into the Constitution a shield the text does not grant. Justices who defend it argue that sovereignty predates the Constitution and that the document’s structure confirms the states never surrendered it. Whether Hans was right as a matter of original meaning is one of the longest-running disagreements in constitutional law, and it is unresolved. What is settled is the doctrine’s shape: unless a state has clearly consented, unless the suit fits Ex parte Young, unless Congress acted under the Fourteenth Amendment, or unless the claim falls within a structural waiver like bankruptcy, eminent domain, or the war powers, a state cannot be sued.
