Tort immunity is a legal doctrine that blocks certain defendants from being sued for civil wrongs, even when their conduct caused real harm. It applies mostly to governments, their employees, judges, and lawmakers, and it exists so that public functions can be carried out without constant threat of personal lawsuits. Some versions are absolute and almost nothing overcomes them. Others are qualified, and they fall away when specific conditions are met. Whether you can sue someone who claims immunity depends on which type they hold, what they were doing when the injury happened, and whether you followed the procedural rules that attach to claims against protected defendants.
The Main Types of Tort Immunity
There are a handful of distinct immunities, and they protect different actors for different reasons.
Sovereign immunity protects governments themselves. Neither the federal government nor any state government can be sued without its consent. The Eleventh Amendment reinforces this for states, and the Supreme Court has interpreted that protection broadly enough to block lawsuits brought by a state’s own residents, not just citizens of other states. Governments can waive this immunity by statute, and all of them have, but always on narrower terms than you’d face suing a private party.
Qualified immunity protects individual government officials, most visibly police officers, from personal liability for constitutional violations committed in the course of their duties. It is a defense raised in response to civil rights suits brought under 42 U.S.C. § 1983.1Office of the Law Revision Counsel. 42 US Code 1983 – Civil Action for Deprivation of Rights
Absolute immunity protects judges acting in their judicial capacity and legislators engaged in core legislative work. It does not depend on good faith or correctness.
Local government immunity protects cities, counties, and school districts, but only when they perform governmental functions. Proprietary activities that resemble private business usually fall outside the shield.
Charitable, volunteer, and family-based immunities are the narrowest category. Most have been abolished or sharply limited by the states, though parental immunity and the federal Volunteer Protection Act still carry weight in specific situations.
Suing the Federal Government Under the FTCA
The Federal Tort Claims Act is the primary route for a tort claim against the United States. It gives federal district courts jurisdiction over suits for money damages when a federal employee, acting within the scope of their job, causes injury through negligence or other wrongful conduct.2Office of the Law Revision Counsel. 28 US Code 1346 – United States as Defendant The government’s liability is measured under the law of the state where the injury happened, so the same accident can produce different legal standards in different places.
You cannot file suit first. Before going to court, you must submit an administrative claim, which is a formal written demand for a specific dollar amount, to the agency whose employee caused the harm. You have two years from the date of injury to file it. The agency then has six months to respond. If it denies the claim, or if six months pass with no answer, you can treat the silence as a denial and proceed to federal court.3Office of the Law Revision Counsel. 28 US Code 2675 – Disposition by Federal Agency as Prerequisite
The dollar amount on that administrative claim becomes a ceiling. Your lawsuit cannot seek more than what you demanded at the agency stage, unless you later uncover evidence that was not reasonably available when you filed.3Office of the Law Revision Counsel. 28 US Code 2675 – Disposition by Federal Agency as Prerequisite Underestimating damages at the start can permanently cap what you recover.
Even a successful FTCA case has built-in limits. Punitive damages are off the table, and so is prejudgment interest.4GovInfo. 28 US Code 2674 – Liability of United States You can recover compensatory damages for medical bills, lost wages, and pain and suffering where state law allows, but you cannot punish the government.
Several categories of claim remain fully immune. The biggest is the discretionary function exception: if the injury resulted from a federal employee exercising judgment or making a policy decision rather than carrying out a clear-cut duty, immunity holds. Claims arising from military combat, postal delivery, tax collection, and most intentional torts are also excluded. A narrow carve-out lets you sue federal law enforcement officers for assault, false arrest, and similar misconduct, but the default rule for intentional wrongdoing by other federal employees is immunity.
Suing a State or Local Government
Every state has passed legislation partially waiving its own immunity, but the terms vary widely. Many states impose a notice-of-claim requirement, which is a formal written notice to the government entity within a set period after the injury. The window can be as short as 30 days. Missing it can permanently bar your case, and courts rarely grant extensions for simple ignorance of the rule.
For local governments — cities, counties, school districts — the key question is whether the entity was performing a governmental or proprietary function at the time of the injury. Policing, firefighting, running courts, and maintaining public roads are governmental functions and are usually immune. Running a parking garage, operating a public utility, or maintaining a municipal golf course looks more like private business, and immunity typically drops away. Courts in different jurisdictions draw this line differently, and activities like street maintenance have been classified both ways.
In some jurisdictions, a local government that purchases liability insurance is treated as having waived immunity up to the policy limits, even without a specific statute authorizing the suit.
Suing an Individual Official: Qualified Immunity
Even when you can get past sovereign immunity, suing the official personally runs into qualified immunity. The Supreme Court set the modern standard in 1982: government officials performing discretionary duties are shielded from personal liability unless their conduct violated a “clearly established” constitutional or statutory right that a reasonable person would have known about.5Library of Congress. Harlow v Fitzgerald, 457 US 800 (1982)
In practice, “clearly established” sets a high bar. Courts typically require a prior case with closely similar facts in which a court found the same type of conduct unconstitutional. If no close-enough precedent exists, the official gets immunity, even if a court later decides the conduct was unlawful. The question shifts from whether the official did something wrong to whether a court had previously said this specific type of wrong was illegal. Those are very different questions, and the second one favors officials far more often than plaintiffs expect.
Qualified immunity covers virtually all executive branch officials exercising judgment in their roles. It does not protect officials performing purely ministerial tasks — routine duties with no room for discretion. An officer following a mandatory protocol who deviates from it cannot claim the deviation was a discretionary choice shielded by the doctrine.
Judges and Lawmakers: Absolute Immunity
Judges have absolute immunity for actions taken in their judicial capacity. Unlike qualified immunity, it does not depend on whether the judge followed the law or acted in good faith. Courts have recognized since at least 1872 that judges must be free to rule on their convictions without worrying about personal lawsuits, even when those rulings are wrong.6GovInfo. Lawrence Moore v Harold F Closz III
The only recognized exception is when a judge acts in the complete absence of all jurisdiction. Not merely exceeding authority within a case properly before them, but doing something with no connection to any judicial function. A judge who issues a terrible ruling in a properly filed case is immune. A judge who orders someone arrested as a personal favor, outside any legal proceeding, may not be. Judicial immunity also does not extend to administrative tasks like hiring and firing staff.
Members of Congress receive a parallel absolute protection under the Speech or Debate Clause of the Constitution. It covers debating bills, voting, drafting legislation, and preparing committee reports. It does not cover a lawmaker’s actions outside the legislative process, like press conferences or intervening in executive branch decisions. State legislatures provide comparable protections, with scope varying by state.
Charitable, Volunteer, and Family Immunities
Charitable immunity once shielded nonprofits from nearly all tort claims. Most states have abolished the doctrine or limited it to specific circumstances, such as capping the damages a charity has to pay. Where some version survives, its scope is usually much narrower than the original blanket protection.
The Volunteer Protection Act of 1997 offers a more targeted federal shield. It protects unpaid volunteers at nonprofits from personal liability for injuries caused by ordinary negligence. It does not cover gross negligence, reckless behavior, or intentional wrongdoing, and some states require the nonprofit to carry liability insurance before its volunteers qualify.
Interspousal tort immunity, which once barred one spouse from suing the other for civil wrongs, has been abolished in most states, with a few retaining limited versions. Parental immunity, which prevents minor children from suing parents for negligent supervision or parenting decisions, has proven more durable. Most states still recognize some form of it, though many carve out exceptions for intentional harm, motor vehicle accidents, and situations where the parent was acting in a business capacity.
When Immunity Does Not Apply
Immunity is broad, but it has consistent weak points.
- Statutory waivers under the FTCA and state tort claims acts open the door to many suits that would otherwise be barred.
- Local governments lose immunity when performing proprietary rather than governmental functions.
- In some jurisdictions, buying liability insurance operates as an implicit waiver up to the policy limits.
- Qualified immunity fails when an official violates a clearly established right, and it does not apply to ministerial tasks.
- Judicial immunity disappears when a judge acts in the complete absence of jurisdiction, and does not cover administrative duties.
- The Volunteer Protection Act does not cover gross negligence, recklessness, or intentional conduct.
- Most intentional torts fall outside the FTCA, but federal law enforcement officers can still be sued for assault, false arrest, and similar misconduct.
What to Do First If You Think Immunity May Apply
Defendants raise immunity early, usually in a motion to dismiss, arguing the court has no authority to hear the case. Courts have held that immunity protects not just against liability but against the burden of standing trial, which is why these questions get resolved before discovery.6GovInfo. Lawrence Moore v Harold F Closz III If the court agrees, the case ends before you present evidence.
Procedural steps come before the merits. For an FTCA claim, you cannot file suit until you have submitted your administrative claim and either received a denial or waited six months.3Office of the Law Revision Counsel. 28 US Code 2675 – Disposition by Federal Agency as Prerequisite Skipping this step is fatal regardless of the strength of your underlying claim. For state and local claims, the notice-of-claim deadline is the first thing to confirm, because missing it is often final.
If you have any reason to think a government entity or official is responsible for your injury, treat the applicable notice and filing deadlines as the controlling fact. The substantive strength of your case does not matter if the procedural door closes first.
