The system of checks and balances affects how the law is made in the U.S. There are three main branches of the government:
- Executive - the president
- Legislative - the congress
- Judicial - the court system
Under this system, no one branch of government can make laws without the guidance and approval of the other.
- The president, for example, has to get the votes and approval from the congress to pass a bill or law.
- The congress can pass a bill or law; but, the president can veto a law that either the House of Representatives or Senate tries to pass.
- If the legislature doesn't like the way a court interpreted something or doesn't like a "rule" a court created in case law, the legislature can then pass a new law changing the rules (provided they get the support from the president and the legislative branch).
- If a law is passed and someone sues to challenge whether that law is constitutional, the Supreme Court gets to take a look and make sure the law doesn't tread on constitutional rights.
