Chavez v. Arte Publico Press
204 F.3d 601 (5th Cir. 2000) - full text opinion
The Eleventh Amendment to the Constitution reads:
The Judicial power of the United States shall not be construed to extend to 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.
It was passed in 1795 in response to the Supreme Court's ruling in Chisholm v. Georgia, which held that states did not enjoy sovereign immunity from suits made by citizens of other states in federal courts. Eleventh Amendment jurisprudence is often confusing, so a good annotated guide to the basics of state sovereign immunity is useful.
