What is the primary function of the judiciary as established by the Constitution?

The primary function of the judiciary, as established by the Constitution, is to interpret laws. This role is crucial because it ensures that the laws enacted by the legislative branch are applied fairly and consistently under the rule of law. The judiciary reviews and resolves disputes regarding the meaning and application of laws, which helps to uphold justice and protect individual rights.

The judicial branch acts as a check on the powers of the other branches of government—executive and legislative—by interpreting statutes and determining their constitutionality. This function supports the framework of checks and balances that is fundamental to the Constitution, ensuring that no branch becomes too powerful and that laws are aligned with constitutional principles.
