Problem: Text: The USPS is often mistaken for a government-owned corporation (e.g., Amtrak) because it operates much like a business. It is, however, an ''establishment of the executive branch of the Government of the United States'', (39 U.S.C. 201) as it is controlled by Presidential appointees and the Postmaster General. As a government agency, it has many special privileges, including sovereign immunity, eminent domain powers, powers to negotiate postal treaties with foreign nations, and an exclusive legal right to deliver first-class and third-class mail. Indeed, in 2004, the U.S. Supreme Court ruled in a unanimous decision that the USPS was not a government-owned corporation, and therefore could not be sued under the Sherman Antitrust Act.
