The concept of "checks and balances" in government refers to the mechanisms built into a political system to ensure that no single branch—executive, legislative, or judicial—gains excessive power. Each branch has defined powers and the ability to limit the actions of the others, promoting accountability and preventing abuse of power. This framework upholds democratic principles and protects citizens' rights by ensuring fair governance. For instance, the legislature may create laws, but the executive can veto them, and the judiciary can declare them unconstitutional if they violate the constitution.
