What mechanism prevents one branch of government from becoming too powerful?

The mechanism that prevents one branch of government from becoming too powerful is the system of checks and balances. This principle is fundamental to the structure of the United States government, established by the Constitution. It ensures that each of the three branches of government—executive, legislative, and judicial—has the ability to regulate and limit the powers of the others.

For example, the legislative branch makes laws, but the executive branch has the power to veto those laws. Conversely, the judicial branch can review laws and declare them unconstitutional if they violate the Constitution. This interplay creates a balance of power, preventing any single branch from overstepping its authority or dominating the others.

This system is crucial for maintaining a democratic government where power is not concentrated in any one group or individual, thereby protecting the rights and liberties of the citizens. Without checks and balances, there would be a risk of tyranny or abuse of power, undermining the principles of freedom and justice.
