American constitutional law

American constitutional law is the body of legal principles that define the structure, powers, and rights established by the U.S. Constitution. It guides how government branches—legislative, executive, and judicial—interact and maintain checks and balances. It also protects individual rights, such as free speech and due process, ensuring government actions align with constitutional limits. Courts interpret and apply these principles in cases, shaping the law and maintaining the country's democratic foundation. In essence, it balances governmental authority with individual freedoms to preserve democracy and justice.
