The purpose of checks and balances in government is to prevent any one branch from exercising unchecked power, ensuring a balance of authority among the legislative, executive, and judicial branches. This system is rooted in the principle of accountability, as each branch has specific powers that can limit the others. For example, the legislative branch can pass laws, but the executive can veto them. The judicial branch can review laws for constitutionality. This interdependence is designed to safeguard democratic governance and protect the rights of citizens by preventing the abuse of power.
