Checks and balances is a system in which each of the three branches of government—the legislative, executive, and judicial—has the ability to limit and control the powers of the other branches. This system helps prevent any one branch from becoming too powerful or abusing its authority. For example, the legislative branch can create laws, but the executive branch can veto them. The judicial branch can interpret laws and determine their constitutionality. By having these checks and balances in place, it ensures a balance of power and helps protect the rights and interests of the people.
