Article Three of the United States Constitution
Eleventh Amendment and state sovereign immunity

In Chisholm v. Georgia, 2 U.S. 419 (1793), the Supreme Court ruled that Article III, Section 2 abrogated the States' sovereign immunity and authorized federal courts to hear disputes between private citizens and States. This decision was overturned by the Eleventh Amendment, which was passed by the Congress on March 4, 1794, 1 Stat. 402 and ratified by the states on February 7, 1795. It prohibits the federal courts from hearing "any suit in law or equity, commenced or prosecuted against one of the United States by Citizens of another State, or by Citizens or Subjects of any Foreign State".
