The United States Supreme Court has determined that the U.S. Postal Service cannot be held liable for damages if it purposefully fails to deliver mail. This ruling, revealed on Tuesday, resulted from a narrow 5-4 decision.

Justice Clarence Thomas penned the majority opinion, which underscored the concept of the government’s sovereign immunity, effectively barring legal claims related to undelivered mail.

Thomas elaborated, saying, “The United States benefits from sovereign immunity and cannot be sued without its consent.” He referenced the Federal Tort Claims Act (FTCA), which maintains sovereign immunity for numerous claims related to mail services.

He further clarified, “The FTCA’s postal exception maintains sovereign immunity for any claims involving the loss, miscarriage, or negligent handling of letters or postal items.” He continued, “This case challenges whether this exception applies when postal employees intentionally fail to deliver mail. We have concluded that it does.”

Meanwhile, former President Donald Trump has commented on a separate Supreme Court matter, suggesting that a ruling against birthright citizenship could advantage China.

The case, U.S. Postal Service v. Konan, stemmed from a dispute between Texas landlord Lebene Konan and her local post office. Konan alleged that postal workers in Euless, Texas, intentionally withheld and returned mail addressed to her and her tenants at two rental properties she owned, causing financial harm and emotional distress.

After her administrative complaints failed, Konan sued the United States in federal court, asserting state law claims including nuisance, tortious interference and conversion. A federal district court dismissed her claims, citing the FTCA’s postal exception, which preserves immunity for “any claim arising out of the loss, miscarriage, or negligent transmission of letters or postal matter.”

The U.S. Court of Appeals for the Fifth Circuit revived the lawsuit, ruling the exception did not apply to intentional acts of nondelivery. The Supreme Court agreed to hear the case to resolve a split among federal appeals courts.

Reversing the Fifth Circuit, the high court held that the ordinary meaning of “loss” and “miscarriage” at the time Congress enacted the FTCA in 1946 encompassed mail that fails to arrive at its destination, regardless of whether the failure was negligent or intentional.

“A ‘miscarriage of mail’ includes failure of the mail to arrive at its intended destination, regardless of the carrier’s intent or where the mail goes instead,” Thomas wrote.

The decision vacates the Fifth Circuit’s ruling and sends the case back for further proceedings, though the justices did not decide whether all of Konan’s claims are barred.

“We hold that the postal exception covers suits against the United States for the intentional nondelivery of mail,” Thomas concluded. “We do not decide whether all of Konan’s claims are barred by the postal exception, or which arguments Konan adequately preserved.

Sotomayor wrote the dissenting opinion, arguing that the postal exception was meant to cover negligent mistakes, not intentional misconduct.

“Today, the majority concludes that the postal exception captures, and therefore protects, the intentional nondelivery of mail, even when that nondelivery was driven by malicious reasons,” she dissented.

Justice Neil Gorsuch joined the three liberal justices – Sotomayor, Elena Kagan and Ketanji Brown Jackson – in the dissent.

The ruling underscores the limits of the FTCA’s waiver of sovereign immunity and narrows the circumstances in which individuals can seek damages for mail-related harms, even when they allege deliberate wrongdoing by postal employees.
