checks and balances
- A system in which the three branches of government - legislative, executive, and judicial - can restrain each other from becoming too powerful, with techniques such as judicial reviews, presidential vetoes, and congressional overrides
- The concept of checks and balances is a foundational idea in the U.S. Constitution to avoid the concentration of power in one single branch of government.
- The president's use of a veto is an example of checks and balances at work, as they can deny a bill that Congress has passed.
- Judicial review, a part of the checks and balances system, enables the courts to determine the constitutionality of laws passed by Congress.
