The concept of checks and balances refers to the system where different branches of government have the authority to limit each other’s powers, preventing any one branch from becoming too powerful. This mechanism is integral to democratic governance, as it fosters accountability and transparency. For instance, the legislature can pass laws, but the executive can veto them. Meanwhile, the judiciary reviews laws for constitutionality. This interplay between branches ensures that they work collaboratively while also holding each other accountable, safeguarding against tyranny.
