U.S. Sovereign Immunity Map
OVERVIEW
In the United States, U.S. states and certain of their instrumentalities, including state government investment and pension funds, enjoy sovereign rights and protections. This survey provides a high-level summary of the sovereign immunity applicable to each of the 50 United States derived from their respective state laws with respect to contract claims. In addition, U.S. states are also entitled to immunity under the Eleventh Amendment to the U.S. Constitution, which provides that a state cannot be sued outside of its home state courts without its consent.
Within each state, specific investment and pension funds may also be subject to more specific laws or policies that are not reflected here. For example, state governments often enjoy greater immunity than municipal governments; but a pension system established to invest funds on behalf of municipal government employees could be constituted as a state agency and entitled to the same level of immunity as the state government. State laws may also include requirements on procedure, time periods, and venues for bringing claims that are not summarized below.
