The concept of "checks and balances" is designed to prevent the abuse of power within a government by ensuring that separate branches can limit each other's functions. In a typical system, the executive, legislative, and judicial branches maintain autonomy while having the authority to oversee and challenge one another. This interdependency safeguards against tyranny and promotes accountability. For instance, legislatures can block executive actions, while courts can review laws’ constitutionality. By distributing power, checks and balances foster a stable government that protects individual rights and encourages responsible governance.
