What stops one branch of government from becoming too powerful?

Why This Matters

The USCIS interviewer asks this question to see if you understand how the government prevents the abuse of power. The answer is checks and balances, also called separation of powers. You can use either term. This system is one of the most important features of American democracy.

Checks and balances means that each of the three branches of government has ways to limit the power of the other two. For example, Congress passes laws, but the President can veto (reject) a law. If the President vetoes a law, Congress can override that veto with a two-thirds vote. The Supreme Court can declare a law unconstitutional, which stops it from being enforced. And the President appoints Supreme Court justices, but the Senate must approve them.

This design was intentional. The Founders studied history and saw that governments with unchecked power often became tyrannies. They wanted a system where power was balanced, so that no branch could dominate the others. The result is a government that sometimes moves slowly, but that protects the rights and freedoms of the people by making sure power is always shared.

Key Facts

• Checks and balances means each branch of government can limit the actions of the other branches
• The President can veto laws passed by Congress, and Congress can override a veto with a two-thirds vote
• The Supreme Court can declare laws or executive actions unconstitutional through judicial review
• The Senate must confirm the President's appointments to the Supreme Court and other federal positions
• Congress has the power to impeach and remove the President or federal judges for misconduct

Common Mistakes

• Saying "the Constitution" stops one branch from becoming too powerful, while the Constitution created the system, the specific answer USCIS wants is "checks and balances" or "separation of powers"
• Confusing "separation of powers" with "states' rights", separation of powers refers to the three branches, while states' rights refers to the division between federal and state governments
• Thinking checks and balances means the branches compete against each other, they actually work together while keeping each other accountable

Study Tip

Imagine three friends sharing a pizza. No one friend can take the whole pizza because the other two will stop them. Each friend checks the others and balances the portions. That is exactly how the three branches work, they share power and watch each other to keep things fair.
