The Eleventh Amendment is the direct result of Chisholm v. Georgia (1793). In that case, the Supreme Court ruled 4–1 that a South Carolina citizen could sue Georgia in federal court under the Article III citizen-state diversity clause. Congress and the states responded within five years with the Eleventh Amendment, ratified in 1795, which bars federal suits against a state by citizens of another state or of a foreign country.

The mechanism: how five Justices gave states a shock

Chisholm arose from a simple debt. During the Revolutionary War, Georgia had purchased supplies from a South Carolina merchant named Robert Farquhar. Georgia never paid. Farquhar's executor, Alexander Chisholm, sued the state in the Circuit Court for the District of Georgia in 1792, seeking roughly 70,000 dollars in modern purchasing power.

Georgia refused to appear. Its lawyers argued that a sovereign state could not be dragged into court by a private citizen without consent. The circuit court split, and the case went to the Supreme Court.

The Court's reasoning rested on the text of Article III, Section 2. That clause extends federal judicial power to controversies "between a State and Citizens of another State." Writing for the majority, Chief Justice John Jay read the clause literally. If a state could sue a citizen of another state, the same language meant a citizen could sue a state.

Four Justices agreed, though they split on rationale. Justice James Wilson grounded the holding in popular sovereignty. Justice James Iredell dissented alone. He argued that Article III's grant of jurisdiction did not by itself override the common-law immunity that sovereign states retained.

The majority treated state sovereignty as a presumption the Constitution had displaced by plain text. Iredell treated it as a background rule courts could not discard without a clearer statement. The legal mechanism matters because it explains the amendment's target. The Court did not invent jurisdiction. It read a jurisprudential clause in an expansive, textualist way that stripped states of an immunity they believed they had kept.

One plain-language version: the Justices said the Constitution's words let citizens haul states into federal court, and the states disagreed so strongly they rewrote the Constitution rather than live with it.

The timeline: a five-year reversal

The amendment's speed is the story. It is one of only a handful of constitutional amendments ratified in under a decade.

Year Event Significance
1777 Georgia buys supplies from Robert Farquhar The unpaid debt seeds the dispute
1792 Chisholm sues Georgia in circuit court Georgia refuses to appear
February 1793 Supreme Court decides Chisholm v. Georgia 4–1 holding that a state can be sued by an out-of-state citizen
February–March 1793 Georgia legislature passes a resolution denouncing the decision States signal constitutional backlash
1794 Congress proposes the Eleventh Amendment Passes the Senate 23–2 and the House 81–9
1795 Ratification reached Twelve states approve; South Carolina and New Jersey reject
1798 Amendment declared in force Proclamation follows the 1798 ratification by New Jersey

The gap between decision and ratification—about two years—understates the intensity. Georgia's legislature threatened to punish anyone who enforced the ruling and urged other states to join a constitutional convention. Several states actively resisted the decision's application.

The counterintuitive detail: the amendment passed with lopsided majorities, but two states voted against it. Some opponents thought the amendment was too narrow, worried it might be read to permit suits against states on federal-question grounds. History proved their worry partly right. The Supreme Court later held in Hans v. Louisiana (1890) that the amendment also barred federal-question suits against states, an interpretation the text does not plainly state.

Quantified context: the amendment reached ratification with only 12 of 14 states voting. That is roughly 86 percent of the states then in the Union. The margin by which it cleared Congress—81–9 in the House—is the kind of supermajority that signals near-consensus.

Edge cases: where the amendment stops

The Eleventh Amendment is narrower than its popular reputation. Its text bars only suits "in law or equity" against a state "by Citizens of another State, or by Citizens or Subjects of any Foreign State."

Three edges matter:

Sovereign immunity doctrine went further than the text. In Hans v. Louisiana (1890), the Court held that a citizen could not sue their own state either, despite the Eleventh Amendment mentioning only out-of-state citizens. The Court inferred a broader structural immunity from the amendment's existence.

Federal law can still reach states, sometimes. In Fitzpatrick v. Bitzer (1976), the Court held that Congress can abrogate state immunity when acting under Section 5 of the Fourteenth Amendment. The carve-out means a statute like Title VII can authorize damages suits against states. That is how the amendment and federal civil-rights law coexist.

The Ex parte Young exception. In 1908 the Court permitted suits for prospective injunctive relief against state officials, as opposed to retroactive money damages against the state treasury. The exception is the workhorse of federal litigation against state policies.

A professional caveat: the term "Eleventh Amendment immunity" is often a misnomer. Modern doctrine rests on a mix of the amendment's text, pre-ratification common law, and implied structural sovereignty. Courts sometimes describe it as constitutional, sometimes as common-law. That dual character produces doctrinal surprises.

Consider one example of an edge case that cuts hard. A state can consent to suit. If a state waives immunity by litigation conduct—say, filing a counterclaim in a suit it could not otherwise face—courts treat the immunity as waived. The waiver mechanism is a doctrine of its own.

Misconceptions: what the amendment is not

The single most common mistake is treating the Eleventh Amendment as a blanket "states cannot be sued" rule. The amendment is both broader and narrower than that.

It cannot be sued at all is false. States can be sued in their own courts under their own law. They can be sued in federal court when they consent. They can be sued for prospective relief against officers. And Congress can erase immunity where it acts under the Fourteenth Amendment.

It is the only constitutional amendment about suing governments is false. Article III, Section 2 also governs jurisdiction over states, and the Fourteenth Amendment's Section 5 gives Congress enforcement power that courts have used to override state immunity in defined contexts.

It settled the question of state sovereign immunity once and for all is false. The amendment's relationship to federal-question suits was not resolved until Hans in 1890, and the doctrine has continued to evolve.

Red flags for anyone relying on the amendment:

Do not assume a claim against a state is barred merely because the plaintiff is from another state—federal statutory abrogation may apply. Do not assume a claim against a state is barred when the defendant is a state agency rather than the state itself; agency status is litigated, not assumed. Do not conflate immunity from suit in federal court with immunity from suit in state court. Do not treat consent as rare; many states waive immunity by statute, contract, or litigation conduct. Do not forget the Ex parte Young injunctive exception if you are seeking policy change rather than damages.

What the amendment delivered and what it left unresolved

The amendment corrected the specific problem Chisholm created: suits by citizens of one state against another state in federal court. It did not, on its face, address suits between a state and its own citizens. It also did not address suits by the United States against a state, a category the Court later treated as surviving immunity in United States v. Texas (2023).

The practical action list for anyone reasoning about this amendment:

Identify the plaintiff's citizenship and the defendant's status first, since the amendment's text turns on both. Check whether the plaintiff seeks damages or prospective relief; the distinction often decides the case. Check whether a federal statute authorizes suit against the state and whether Congress acted under the Fourteenth Amendment. Check state law and state constitutional provisions, which can be more plaintiff-friendly than federal immunity. Document any state conduct that could constitute waiver, such as a counterclaim in a suit the state could not have faced.

Thresholds are often reconciled in two places. In statutory abrogation cases, courts ask whether the statute unambiguously creates a private damages remedy against states. In waiver cases, courts ask whether state conduct in litigation was voluntary and deliberate enough to show an intent to waive. The two tests are different legal tests, and they can produce different outcomes on nearly identical facts. Avoid applying a single threshold across both.

Limitations: what a deep dive cannot resolve

The historical record is not complete. The Court's reasoning in Chisholm is known from the report, but political pressure on ratifying states is documented unevenly. The amendment's ratification by 12 of 14 states does not tell us how many citizens opposed it. Scholars disagree about how much the amendment reshaped the law versus codified an existing understanding.

Modern doctrine is also unstable. The Supreme Court has revisited state sovereign immunity in decisions involving bankruptcy, patent law, and federal administrative adjudication. Any statement about the amendment's scope is a snapshot of current doctrine rather than a fixed rule. That is a general educational point, not legal advice.

A final limitation worth stating plainly: the case is often taught as a story of judicial arrogance corrected by amendment. That framing is too neat. The Court's textual reading was defensible on Article III's words, and the amendment's narrow text later required judicial expansion to achieve the outcome its backers wanted. The episode illustrates how constitutional text, political backlash, and judicial doctrine interact across decades, not a single correction.

The Eleventh Amendment answers the question with unusual clarity: Chisholm v. Georgia is the case, 1793 is the year, and the amendment is the direct result. The deeper lesson is that a single clause reading, applied literally, can trigger a constitutional response faster than almost any other kind of decision.
