can you sue the united states postal service
Dolan v. United States Postal Service, 546 U.S. 481 (2006), was a case decided by the Supreme Court of the United States, involving the extent to which the United States Postal Service has sovereign immunity from lawsuits brought by private individuals under the Federal Tort Claims Act. The Court ruled that an exception to the FTCA that barred liability for the ``negligent transmission of mail'' did not apply to a claim for injuries caused when someone tripped over mail left by a USPS employee. Instead, the exception only applied to damage caused to the mail itself or that resulted from its loss or delay.
