Answer:
- Dividing the government into branches.
- Having a constitutional court.
Explanation:
It helps in setting boundaries for the judiciary, legislature, and the executive by separating powers in the three branches of government, this way each different branch will make sure the other branches act correctly according to the constitution. Also, there's a constitutional court that makes sure the interpretation of the constitution is correct and that laws passed are aligned with its mandates, in the United States this is the job of the Supreme Court.
