The U.S. system of checks and balances is designed to prevent any one branch of government—executive, legislative, or judicial—from becoming too powerful. Each branch has specific powers and responsibilities, allowing them to limit and oversee one another. For instance, Congress can pass legislation, but the President can veto it, while courts can review laws for constitutionality. This framework promotes accountability and encourages collaboration among branches, ensuring that governance reflects a balance of interests and protects the rights of citizens.
