Separation of Powers: Separation of powers refers to the division of government responsibilities among different branches (legislative, executive, judicial) in order to prevent any one branch from becoming too powerful.
Checks and Balances: Checks and balances are mechanisms built into the U.S. government system that ensure no single branch becomes too dominant by providing each branch with ways to limit or control the actions of other branches.
Legislation: Legislation refers to laws passed by a legislative body such as Congress. It includes statutes enacted by Congress as well as regulations established by government agencies based on those statutes.
