Interposition is a political theory that suggests a state has the right to intervene between its citizens and the federal government. This concept is often associated with the idea that states can protect their residents from federal actions they believe are unconstitutional or harmful. Historically, interposition has been invoked during conflicts over civil rights and federal authority. For example, during the Civil Rights Movement, some states attempted to use interposition to resist federal laws aimed at desegregation. This theory raises questions about the balance of power between state and federal governments in the United States.
