which waives the immunity over claims arising out of contracts to which the federal government is a party. The United States as a sovereign is immune from suit unless it unequivocally consents to being sued. The United States Supreme Court in Price v. United States observed: "It is an axiom of our jurisprudence. The government is not liable to suit unless it consents thereto, and its liability in suit cannot be extended beyond the plain language of the statute authorizing it." Price v. United States, 174 U.S. 373, 375-76 (1899). State sovereign immunity In Hans v. Louisiana (1890), the Supreme Court of the United States held that the Eleventh Amendment (1795) re-affirms that states possess sovereign immunity and are therefore generally immune from being sued in federal court without their consent.
