A check on other branches of government refers to the mechanisms and processes established to ensure that no single branch of government becomes too powerful or abuses its authority. This concept is rooted in the principle of separation of powers, where each branch—executive, legislative, and judicial—has distinct responsibilities and the ability to limit the powers of the others. This creates a system of accountability and balance within the government structure, ensuring that legislation is reviewed, executive actions are scrutinized, and judicial decisions can be contested.
