the decision two years later in Fitzpatrick." Althouse, Vanguard States, supra, at 1791 n.216 The 42 U.S.C. § 1983 allows state officials to be sued in their individual or official capacities, a principle which was demonstrated again in Brandon v. Holt. Suits as to which Congress has abrogated the states' Eleventh Amendment immunity The federal government and nearly every state have passed tort claims acts allowing them to be sued for the negligence, but not intentional wrongs, of government employees. The common-law tort doctrine of respondeat superior makes employers generally responsible for the torts of their employees. In the absence of this waiver of sovereign immunity, injured parties would generally have been left without an effective remedy. See Brandon v. Holt.

Flores. But "[t]he ultimate interpretation and determination of the Fourteenth Amendment's substantive meaning remains the province of the Judicial Branch." Kimel v. Florida Board of Regents. Simply put: "Under the City of Boerne doctrine, courts must ask whether a statutory remedy has 'congruence and proportionality' to violations of Section 1 rights, as those rights are defined by courts." Althouse, Vanguard States, Laggard States: Federalism & Constitutional Rights, 152 U. Pa. L. Rev. 1745, 1780 (2004) States can expressly waive sovereign immunity, but do not do so implicitly simply by participating in a commercial enterprise where Congress subjects market participants to lawsuits. College Savings Bank v. Florida Prepaid Postsecondary Education Expense Board. The Court has found that somewhat different rules may apply to Congressional efforts to subject the states to
