State sovereign immunity recognizes the “residuary and inviolable sovereignty” that states retain under the Constitution. Alden v. Maine, 527 U.S. 706, 715 716 17, 119 S. Ct. 2240, 2247, 2248 (1999) (quoting The Federalist Papers No. 39 at 245 (James Madison) and No. 81 at 487-88 (Alexander Hamilton) for a similar proposition, “It is inherent in the nature of sovereignty not to be amenable to the suit of an individual
without its consent” and “is now enjoyed by the government of every State in the Union” (emphasis in
Alden)). The Second Circuit has recognized two “species” of state sovereign immunity. Initially, the Eleventh Amendment identifies an immunity of a state's treasury from claims for damages brought by private entities. Beaulieu v. Vermont, 807 F.3d 478, 483 (2d Cir. 2015) (citing Seminole Tribe of Fla v. Florida, 517 U.S. 44, 54, 116 S. Ct. 1114, 1122 (1996)). This immunity protects a state's “dignity and fiscal integrity from federal judgments” and operates as a limit on the federal courts’ Article III powers.
Id. (citing Alden, 527 U.S. at 716-21, 119 S. Ct. at 2248-50; Woods v. Rondout Valley Cent. Sch. Dist. Bd. of Educ., 466 F.3d 232, 240 (2d Cir. 2006); In re Charter Oak Assocs., 361 F.3d 760, 765 (2d Cir. 2004)). States, however, also have a broader sovereign immunity, beyond that addressed in the Eleventh Amendment, applying to all private suits—in state or federal court. Beaulieu, 807 F.3d at 483. This broader immunity is a “fundamental aspect” of state sovereignty that predates the Constitution and is not limited by the Eleventh Amendment. Alden, 527 U.S. at 713, 119 S. Ct. at 2246-47. Sovereign immunity applies both to the states and their agencies. Regents of the Univ. of Cal. v. Doe, 519 U.S. 425, 429, 117 S. Ct. 900, 903 (1997).
