The question

Whether the Federal Tort Claims Act's postal exception, which preserves federal sovereign immunity for claims arising out of the loss, miscarriage, or negligent transmission of mail, bars claims arising from the Postal Service's intentional failure to deliver mail.

Postal Service v. Konan

What the Court decided

Reversed. The United States keeps its sovereign immunity from tort claims arising out of the intentional nondelivery of mail. The Court held that both "miscarriage" and "loss" of mail under the FTCA's postal exception can occur when the Postal Service intentionally fails to deliver mail, reading those 1946 statutory terms by their ordinary meaning. Konan's state-law tort claims that Postal Service employees intentionally withheld her mail therefore fall within the exception and cannot proceed.

The Court's opinion

Thomas, joined by Roberts, Alito, Kavanaugh, Barrett

The postal exception reflects Congress's judgment that redress for harms tied to the Postal Service's function of transporting mail should not come from tort suits. Read by their ordinary 1946 meanings, both 'miscarriage' and 'loss' of mail reach intentional conduct. 'Miscarriage' covered any failure of mail to arrive at its intended destination and was used for intentional misconduct like stolen or burned mail, with no dictionary limiting it to negligence or to misdelivery. 'Loss' meant a deprivation of mail regardless of how it came about, including when someone intentionally keeps the mail. Because Konan alleged the Postal Service converted mail she was entitled to possess, her claims arise out of the loss and miscarriage of mail and are barred.

Dissenting

Sotomayor, joined by Kagan, Gorsuch, Jackson

The dissent would hold that the postal exception does not preserve immunity for the intentional nondelivery of mail alleged here. The syllabus does not set out the dissent's full reasoning.
