Checks and balances exist to keep the executive, legislative, and judicial branches equal. Some examples of checks and balances in the Constitution include:
- The president's power to veto a bill (executive check on the legislative branch)
- The House's power to impeach (legislative check on both the executive branch and the judicial branch)
- Both houses of Congress must pass each bill (legislative self-check since this branch is bicameral with both the House and the Senate)
- Judicial review (judicial check on both the legislative branch and the executive branch)
- The president's pardon power (executive check on the judicial branch)
These are just a few. Let me know if you have any questions.
