As we noted in this post last week, Michigan, New York, Ohio are the only states in which the courts of claims are within the judicial branch rather than the executive or legislative branch. If you want to know more you might consult "A Review of State Sovereign Immunity Statutes and the Management of Liability Risks by States" in the Journal of Insurance Regulation. (It has a handy chart of all the states.) From the abstract:
The liability exposure in the majority of states is limited by law, specifically states’ sovereign immunity statutes. However, the sovereign immunity of states and state entities have been challenged in both federal and state courts for nearly 200 years. This article reviews the principle of sovereign immunity, the sovereign immunity statutes of the states, and how states manage risk. It also discusses relevant case law and recent legislative activity related to these statutes and how the outcome may impact the risk management decision of states.
