Legal Definitions - intergovernmental immunity

Intergovernmental immunity is a type of immunity that exists between the federal and state governments based on their independentsovereignty. It means that one government cannot be sued by the other without its consent.

For example, if a state government wants to sue the federal government for damages caused by a federal project, it cannot do so without the federal government's consent. Similarly, if the federal government wants to sue a state government for violating federal law, it cannot do so without the state government's consent.

This immunity is based on the idea that each government is a separate entity with its own powers and responsibilities, and that they should not interfere with each other's affairs.
