What does the judicial branch do?

The judicial branch of government is primarily responsible for interpreting laws and ensuring that they align with the Constitution. This involves reviewing laws, evaluating their implications, and determining whether they adhere to constitutional principles. When the judicial branch decides if laws are constitutional, it serves as a check on the legislative and executive branches of government, ensuring that no law violates the rights and freedoms guaranteed by the Constitution. This function is vital for maintaining the rule of law and protecting individual rights within a democracy. Through court cases and judicial reviews, judges play an essential role in the system of checks and balances that underpins the United States government.
