The Legal Immunity Shielding USPS

Last updated 5 days ago. Our resources are updated regularly but please keep in mind that links, programs, policies, and contact information do change.

A check never shows up. A birthday package arrives looking like it lost a fight with a garbage truck. A legal notice lands a week after the deadline it was warning you about.

The natural next thought, once the frustration cools, is a question: can I sue the Postal Service for this?

Under current federal law, the answer is usually no.

When the harm flows from how the mail itself was carried, delivered, or not delivered, a single statutory rule blocks ordinary lawsuits and pushes your dispute into insurance claims and complaint forms instead. That rule is the Federal Tort Claims Act’s postal exception, tucked into 28 U.S.C. § 2680(b). It says the government’s general consent to be sued does not cover “any claim arising out of the loss, miscarriage, or negligent transmission of letters or postal matter.”

Two Supreme Court cases draw the line that matters to you.

In 2006, Dolan v. United States Postal Service said the shield does not cover every accident that happens near your mail. In 2026, Postal Service v. Konan stretched it to cover mail a carrier withholds on purpose.

Why the Government Has to Say “Yes” Before You Can Sue

Start with a rule most people never think about. You cannot sue the United States unless the United States has agreed to let you.

That is sovereign immunity, and it is old. The government is shielded from lawsuits by default, and only Congress can lift the shield. We walk through the broader doctrine in our piece on when you can sue the government, but the short version is this: no consent, no case.

The main piece of consent is the Federal Tort Claims Act. Under 28 U.S.C. § 1346(b)(1), federal courts can hear claims against the United States for injury or property damage caused by a government employee’s negligent or wrongful act. The standard is the same state law that would apply to a private person in the same spot.

So if a private delivery driver could be sued for it, the government can often be sued too. That is the door.

But the door has locks. Section 1346 is expressly limited by a list of exceptions in § 2680, and the list is long: discretionary policy decisions, tax and customs collection, quarantine, combatant activities, certain claims arising abroad. One of those locks is the postal exception in subsection (b).

Here is the part that trips people up. The exception applies even when a postal worker was plainly negligent and even when state law would let you sue a private carrier for the identical failure. If the claim fits inside § 2680(b), the court never considers whether you’re right. It throws the case out because the court has no power to hear it: Congress never handed over the keys for that category.

The Postal Service, remember, is an arm of the federal government. That public status is exactly what makes the FTCA and its postal exception apply. UPS and FedEx have no such shield.

The Line Barbara Dolan Drew

The clearest way to see where the shield ends is to watch someone walk right up to its edge.

Barbara Dolan, a Pennsylvania resident, tripped over packages a carrier had left on her porch and hurt herself. She sued under the FTCA, arguing the carrier created a tripping hazard, the same way you might sue any delivery driver who left a box in a dangerous spot.

The government moved to dismiss. Her injury, it argued, arose out of the “negligent transmission” of mail, because placing packages on a porch is part of delivering them. Both the district court and the appeals court accepted that reading and threw her claim out.

The Supreme Court disagreed.

The Justices read “negligent transmission” narrowly. It means negligence that causes mail to be lost, or to arrive late, damaged, or at the wrong address. It does not mean every careless act a carrier commits while mail happens to be in their hands. The exception, the Court said, targets harms “primarily identified with the Postal Service’s function of transporting mail.”

Dolan’s fall was not about her mail failing to arrive. Her mail arrived fine. It was about a hazard on her steps, so her claim could proceed.

The Court leaned on an earlier decision, Kosak v. United States, to explain the point. One purpose of the FTCA was to let people sue over crashes involving postal trucks.

Read “negligent transmission” too broadly and you would immunize the very collisions Congress most wanted to allow lawsuits over. The drafters, the Court noted, had carefully delineated the types of misconduct for which the Government was not assuming financial responsibility.

Dolan gave lower courts a workable rule.

Konan and the Mail That Was Withheld on Purpose

Dolan settled what “negligent transmission” means. It left a different question open: what about mail a postal worker deliberately refuses to deliver? That is not negligence at all. It is a choice.

Lebene Konan, a Texas landlord, said that is exactly what happened to her. She alleged that Postal Service employees intentionally and wrongfully withheld mail addressed to her and her tenants, and she brought state-law tort claims over the financial and personal harm that followed.

As the court framed it, Konan concedes that USPS is the appropriate defendant in this FTCA action but disputes whether sovereign immunity shields it from liability.

The Fifth Circuit answered that the terms “loss,” “miscarriage,” and “negligent transmission” do not encompass the intentional act of not delivering the mail at all. It affirmed the dismissal of her constitutional claims and reversed on the FTCA claim.

That created a disagreement among the appeals courts. The First and Second Circuits had applied the exception even to intentional misconduct. The Supreme Court took the case to sort it out.

The question presented was precise: “Whether a plaintiff’s claim that she and her tenants did not receive mail because Postal Service employees intentionally did not deliver it to a designated address arises out of ‘the loss’ or ‘miscarriage’ of letters or postal matter.”

On February 24, 2026, the Court said yes. Both “loss” and “miscarriage,” it held, can happen through intentional acts as easily as careless ones.

The reasoning turned on a small but decisive word choice. Writing for the majority, Justice Thomas noted that § 2680(b) describes harms, not actions. Congress barred any “claim[s] arising out of the loss, miscarriage, or negligent transmission” of mail without ever distinguishing between a worker who was sloppy and one who was malicious. The statute cares about what happened to the mail, not what was in the employee’s head.

The bottom line is that the postal exception bars suits against the federal government over the intentional nondelivery of mail.

Justice Sonia Sotomayor, joined by Justices Kagan, Gorsuch, and Jackson, dissented. She criticized the majority for shielding nondelivery even when driven by malice, warning that it hands USPS more protection than Congress meant to give.

Put Dolan and Konan together and you get a shield that is narrow in one direction and wide in another. Narrow because it only covers harms tied to the fate of the mail. Wide because within that zone it covers both the careless and the deliberate.

What You Can and Cannot Sue USPS For

Here is the practical map most people need.

Source: 28 U.S.C. § 2680(b), as interpreted in Dolan and Konan. Vehicle and premises claims must still satisfy the FTCA’s other requirements.

Two examples show the barred side. A sender whose Priority Mail package of valuables never arrives cannot go to court for the replacement value, even alleging the parcel was negligently misdirected. A small business that loses a contract because its mailed proposal shows up after the deadline cannot recover the lost profits. Both harms trace straight back to the mail’s failure to arrive on time, and § 2680(b) closes the door.

Andrea McNairy, an attorney at the firm Brown & Crouppen, discussed the topic for viewers on a local “Legal Lens” TV segment. Asked whether you can sue the post office over undelivered mail, the segment gave the answer as no. That bar does not apply to private carriers like UPS, which are not government entities. You can still sue over a crash caused by a USPS vehicle, subject to specific rules.

That distinction between public and private carriers is worth dwelling on. It is not that FedEx and UPS are generous. Their liability is capped too, but by contract rather than statute.

FedEx says a package’s declared value sets its maximum exposure for loss, damage, delay, or misdelivery, and you must prove both your actual damages and FedEx’s fault. UPS caps liability per package through its tariff.

The difference is that with a private carrier, you can at least walk into court. With USPS, for mail-content harms, you often cannot.

The Recourse That Actually Exists

If the courthouse is closed for lost or damaged mail, where do you go? The system Congress built points you somewhere else: insurance and administrative claims.

For a lost or damaged item, the path runs through USPS’s own claims process. It works only if the service you used carried insurance or you bought it. Priority Mail claims, for instance, must be filed after 15 days and before 60 days. We walk through the mechanics in our guide to claiming USPS insurance.

Coverage limits are modest. Notice what that buys: the insured value, not the knock-on losses that follow. It will not cover the contract your late proposal cost you.

Which is the whole logic of the exception in one sentence. Congress traded the open-ended risk of tort suits for a capped, administered insurance system, and told you to buy coverage up front for anything that matters.

Now the other branch. If a postal truck hits you, or you are hurt by conduct that is not about the fate of your mail, the FTCA door is open. The key that unlocks it is Standard Form 95.

SF-95 is the government-wide administrative tort claim form, though using it isn’t mandatory as long as a written claim states a sum certain and meets the other basic requirements. You fill in your information, the date and time of the incident, a narrative of what happened, the nature and extent of your injury or property damage, and a specific dollar amount claimed. A blank or vague damages figure can sink the claim.

Timing is unforgiving. Under 28 U.S.C. § 2401(b), you must present a written claim to the agency within two years of when it accrues, then wait. Only after the agency denies your claim, or lets six months pass without resolving it, can you sue in federal court.

One more rule catches people. When you finally sue, the defendant is the United States, not the Postal Service. Name the agency and courts throw the case out because they have no power to hear it. The FTCA treats every covered claim as a claim against the federal government itself.

The Accountability Debate After Konan

Dolan drew a line the public could mostly live with. Konan is the one that set off alarms, because it reached intentional, even malicious, misconduct.

Sue the agency and sovereign immunity blocks you; sue the individual carrier for the tort and the Westfall Act (28 U.S.C. § 2679(b)(1)) swaps in the United States as the defendant, dropping the claim right back into the FTCA — where the postal exception bars it again. A constitutional claim against the carrier, like Konan’s discrimination claim, runs into qualified immunity and the near-closure of Bivens instead.

The decision “narrows the availability of damages remedies,” and people harmed by intentional withholding “will now face obstacles in seeking monetary damages under the FTCA.”

The reaction traveled fast outside legal circles. One social-media post distilled it to a single shareable line: Americans can’t sue the U.S. Postal Service, even if the post office maliciously held back your mail, the Supreme Court ruled this week. One blog post by an ordinary citizen granted that immunity for routine lost mail is not unreasonable, but criticized the ruling extending immunity to the intentional withholding of mail.

The strongest argument on the other side is not hard to state. USPS moves a staggering volume of mail, and case-by-case tort trials over every lost letter would swamp both the agency and the courts. The insurance system spreads that risk instead, using receipts, declared values, and deadlines rather than juries. Justice Thomas’s majority framed the exception as Congress’s deliberate choice to keep redress for mail-transport harms out of the tort system entirely.

USPS is not immune everywhere. Under 39 U.S.C. § 401(1), it carries a general “sue and be sued” clause. When it competes in areas open to private companies, it’s treated like any business, with no sovereign-immunity defense against lawsuits over monopoly abuse and unfair competition. The broad shield exists precisely where the agency performs its core monopoly function: carrying the mail.

Two Silences That Shape the Whole Debate

Here is what makes this argument oddly hard to resolve: two things nobody has.

The first is data. No comprehensive public tally is regularly published for how many tort claims against USPS get dismissed under § 2680(b), or how many insurance claims are filed, paid, or denied in aggregate. The doctrine is precise; its real-world impact is a mystery.

Whether the exception mostly blocks frivolous suits or quietly denies real victims, no one can say from the record. The debate runs on cases and anecdotes because the numbers do not exist.

The second silence is legislative. Because this immunity is a statute, not a constitutional command, Congress could rewrite it tomorrow. It has not.

The Postal Service Reform Act of 2022, signed April 6, 2022, was the big recent overhaul. It repealed the retiree health prefunding mandate, created a Postal Service Health Benefits Program, and codified that the Postal Service shall deliver mail 6 days per week. What it never touched was § 2680(b). Later measures, including Representative Zoe Lofgren’s effort to protect the Postal Service and the bipartisan Postal Processing Protection Act, focused on finances, facilities, and service standards. The liability shield stayed off the table.

That silence cuts both ways, depending on where you sit. Read it as consensus that the exception works, or as a shield too politically settled to touch. Either way, the machinery that decides whether you can sue over your mail was built by Congress, and only Congress can rebuild it.

For now, the rule for anyone staring at a lost check or a withheld letter is the one the courts have handed down. If your harm is about whether the mail arrived, your remedy is insurance and a complaint, not a lawsuit. When your harm is about how USPS conduct injured you or your property, off the page of mail delivery, SF-95 is your route in.

Whether Konan proves durable, or whether a future Congress decides malicious nondelivery deserves a day in court, is the open question the ruling leaves behind.
