Sovereign immunity is a legal doctrine that prevents you from suing a government unless that government has agreed to be sued. It protects the federal government, all 50 states, and federally recognized tribal nations from money-damages claims by default, and it covers their agencies and officials acting in official roles. The doctrine is not absolute. Congress and state legislatures have passed statutes that waive immunity for specific kinds of claims, and the Constitution itself creates a few paths around it. Winning a case against a government almost always comes down to fitting your claim into one of those openings.
Why Governments Have This Protection
The doctrine traces back to the English common law principle that “the king can do no wrong.” The American founders carried a modified version forward. The Eleventh Amendment, ratified in 1795, bars federal courts from hearing lawsuits brought against a state by citizens of another state or by foreign citizens.1Library of Congress. U.S. Constitution – Eleventh Amendment The Supreme Court later read that protection much more broadly than its text suggests. In Hans v. Louisiana (1890), the Court held that states are also immune from suits by their own citizens in federal court, and in Alden v. Maine (1999), it extended state sovereign immunity to state courts as well.2Legal Information Institute. General Scope of State Sovereign Immunity
The practical reason: if anyone could sue the government for money at any time, public treasuries would be under constant siege, and agencies would spend more time in court than doing their jobs. Immunity forces disputes into structured channels.
Who Is Protected and Who Is Not
Federal sovereign immunity shields the United States, its agencies and departments, and federal employees acting within their official duties. Without a congressional waiver, federal courts have no jurisdiction over claims for money against the Treasury.
State sovereign immunity covers the state itself, its agencies, state universities, and state officers sued in their official capacity. If a lawsuit would effectively require paying money from the state treasury to remedy past harm, courts treat it as a suit against the state no matter who is named.3Legal Information Institute. Exceptions to Eleventh Amendment Immunity – Officer Suits A state can waive the protection, but a statutory waiver is only effective 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.”4Legal Information Institute. Waiver of State Sovereign Immunity A state also waives immunity by initiating litigation or voluntarily taking part in a case.
Cities, counties, and other local government bodies do not share this constitutional immunity. They are subdivisions of the state rather than sovereigns, and the Eleventh Amendment does not shield them. Many states extend a narrower governmental immunity to municipalities that limits tort liability, but the scope varies state to state.
Federally recognized Native American tribes have their own inherent immunity as sovereign nations. It covers tribal government operations and commercial businesses, on and off reservation land. The Supreme Court reaffirmed this in Michigan v. Bay Mills Indian Community (2014). A tribe can be sued only if Congress has specifically authorized it or the tribe itself has waived immunity clearly and unequivocally.
Suing the Federal Government for Injuries: The FTCA
The Federal Tort Claims Act is the main route for suing the federal government over injuries caused by federal employees. It gives federal district courts jurisdiction over claims for personal injury, death, or property damage caused by a federal employee’s negligent or wrongful conduct within the scope of employment.5Office of the Law Revision Counsel. 28 U.S. Code 1346 – United States as Defendant The government’s liability is measured the same way a private person’s would be under the law of the state where the incident happened.
Two limits matter upfront. You cannot recover punitive damages against the federal government under the FTCA; only actual, compensatory damages are available.6Office of the Law Revision Counsel. 28 USC 2674 – Liability of United States Pre-judgment interest is also off the table.
You Have To File an Administrative Claim First
You cannot skip straight to court. Before filing an FTCA lawsuit, you must first submit an administrative claim to the federal agency responsible for the injury.7Office of the Law Revision Counsel. 28 U.S. Code 2675 – Disposition by Federal Agency as Prerequisite Courts dismiss cases that skip this step.
The claim has to include your name, a description of the injury or damage with the date, and a specific dollar amount. Money is the only remedy. Most people use Standard Form 95, though the form itself is not technically required. You have two years from the date you knew or should have known about the injury to file.
Once the agency has your claim, it has six months to respond. If it denies the claim, you have six months from the date of the denial letter to sue in federal district court.8eCFR. Administrative Claims Under the Federal Tort Claims Act and Related Claims Statutes If the agency simply doesn’t answer within six months, you can treat the silence as a denial and go to court.7Office of the Law Revision Counsel. 28 U.S. Code 2675 – Disposition by Federal Agency as Prerequisite Miss either deadline and your case is dead.
What the FTCA Does Not Cover
The waiver has a long list of carve-outs where the government stays fully immune. This is where many claims collapse. People assume the FTCA covers any negligence by any federal employee. It does not. Excluded categories include:9Office of the Law Revision Counsel. 28 U.S. Code 2680 – Exceptions
- Discretionary functions. Any claim based on a federal employee’s decision involving policy judgment is excluded, even when the judgment was wrong. This is the broadest and most frequently litigated exception. Courts ask whether the conduct involved an element of judgment or choice, and whether that judgment was the kind of policy-grounded decision the exception was designed to protect.
- Most intentional torts. Claims for assault, battery, false imprisonment, false arrest, libel, slander, misrepresentation, deceit, and interference with contract rights are excluded. One important exception: federal law enforcement officers can be sued for assault, battery, false imprisonment, false arrest, abuse of process, and malicious prosecution.
- Tax and customs disputes, including assessment, collection, and the detention of goods by law enforcement.
- Damages caused by a quarantine imposed by the United States.
- Treasury Department fiscal operations and monetary policy.
- Lost, misdirected, or negligently transmitted mail.
Suing the Federal Government for Breach of Contract: The Tucker Act
If your dispute is a broken contract rather than an injury, the Tucker Act is your route. It gives the U.S. Court of Federal Claims jurisdiction over claims against the United States based on the Constitution, federal statutes, executive regulations, or contracts with the government.10Office of the Law Revision Counsel. 28 U.S. Code 1491 – Claims Against United States Generally The claim must seek money and cannot sound in tort. Federal contractors, suppliers, and anyone with an express or implied contract with the government can use it.
Suing a State
Nearly every state has passed its own tort claims act waiving immunity for certain negligence and civil wrongs by state employees. These statutes follow the FTCA structure: they open the courthouse door but impose conditions. Most require a formal notice of claim with the responsible agency before you can sue, and the deadlines are tight, commonly from 90 days to two years. Many states cap total damages, often between $100,000 and $500,000, sometimes with separate caps for individual claims and multi-victim incidents. Virtually all state tort claims acts carry their own discretionary function exception. Your first step is identifying your state’s statute and its filing requirements.
When Congress Can Override State Immunity
The Supreme Court held in Fitzpatrick v. Bitzer (1976) that Congress can override state sovereign immunity when it legislates under Section 5 of the Fourteenth Amendment.11Library of Congress. Fitzpatrick v. Bitzer, 427 U.S. 445 (1976) Because the Fourteenth Amendment limits state authority, Congress can create private lawsuits against states to enforce it. This power is limited to enforcing the substantive provisions of the Fourteenth Amendment, including equal protection and due process. Legislation based on other constitutional powers, like the Commerce Clause, cannot abrogate state immunity.12Library of Congress. Amdt14.S5.4 Modern Doctrine on Enforcement Clause Title VII of the Civil Rights Act is the classic example of a statute that validly uses this power to let employees sue state governments for workplace discrimination.
Suing State Officials To Stop Unconstitutional Conduct
Even when the state is immune from a damages suit, you can sometimes sue a state official directly to stop them from enforcing an unconstitutional law. The Supreme Court’s 1908 decision in Ex parte Young held that a state officer enforcing an unconstitutional statute is “stripped of his official character” and can be sued as an individual.13Justia Law. Ex Parte Young, 209 U.S. 123 (1908) The catch: this doctrine only allows prospective relief, meaning a court order stopping future conduct. It does not reach money damages for past harm.
Civil Rights Claims Against Officials and Local Governments
42 U.S.C. ยง 1983 lets you sue anyone acting “under color of” state law who deprives you of a right secured by the Constitution or federal law.14Office of the Law Revision Counsel. 42 U.S. Code 1983 – Civil Action for Deprivation of Rights Police officers, prison guards, public school administrators, and other government employees all fall within reach when their conduct violates your rights.
Section 1983 does not override state sovereign immunity. You cannot use it to sue a state or a state agency for money damages. You can sue the individual official, and you can sue local governments. The Supreme Court held in Monell v. Department of Social Services (1978) that a city or county can be liable under Section 1983 when the violation resulted from an official policy or established custom.15Library of Congress. Monell v. Department of Social Services, 436 U.S. 658 (1978) A local government is not liable just because it employed the person who caused the harm. You have to show the violation flowed from a deliberate policy choice or a pattern persistent enough to amount to official custom.
Qualified Immunity Is a Separate Shield
Sovereign immunity protects the government entity. Qualified immunity protects the individual government employee from paying damages personally. Confusing the two is a common mistake.
Under Harlow v. Fitzgerald (1982), government officials performing discretionary functions are shielded from civil damages as long as their conduct did not violate “clearly established statutory or constitutional rights of which a reasonable person would have known.”16Justia Law. Harlow v. Fitzgerald, 457 U.S. 800 (1982) Courts ask two questions: did the conduct violate a constitutional right, and was that right clearly established at the time? The “clearly established” prong is demanding. It is usually not enough to show the behavior was wrong in the abstract. Plaintiffs typically have to point to a prior court decision with similar facts that put the official on notice. The defense comes up most often in Section 1983 cases against law enforcement for excessive force or unlawful arrest.
When the Government Takes Your Property
The Fifth Amendment requires the government to pay just compensation when it takes private property for public use, and that requirement applies to states through the Fourteenth Amendment. When the government takes or damages your property without formal condemnation and without paying, you can bring an inverse condemnation action to recover compensation. Because the Constitution itself commands payment, sovereign immunity does not block these claims. The obligation to pay for what the government takes exists regardless of consent to be sued.
A Note on Foreign Governments
Foreign governments are not covered by the doctrine discussed above. Their immunity in American courts runs through a separate statute, the Foreign Sovereign Immunities Act, which starts from immunity and then creates specific exceptions for commercial activity, torts occurring in the United States, and certain property disputes.17Office of the Law Revision Counsel. 28 U.S. Code 1604 – Immunity of a Foreign State From Jurisdiction18Office of the Law Revision Counsel. 28 U.S. Code 1605 – General Exceptions to the Jurisdictional Immunity of a Foreign State The FSIA is the sole basis for jurisdiction over a foreign state in American courts; if none of its exceptions apply, the foreign government cannot be sued here no matter how strong the underlying claim.
