What does the judicial branch primarily do?

The judicial branch primarily interprets laws, which involves evaluating and determining the constitutionality of laws and their applications in specific cases. This function is essential to ensure that laws align with the Constitution and protect individual rights. Courts, judges, and justices play a critical role in this process by reviewing cases brought before them and making rulings based on existing statutes and legal precedents.

Through interpretations, the judicial branch resolves disputes and provides clarity on how laws should be understood and applied, thereby maintaining the rule of law. This function is foundational to the checks and balances system within the U.S. government, ensuring that the legislative and executive branches operate within the limits set by the Constitution.
