What does Chief Justice Marshall assert is the role of the judicial department?

Chief Justice John Marshall emphasized the role of the judicial department as one of interpretation rather than enactment or enforcement of the law. This principle is particularly evident in the landmark case of Marbury v. Madison, where he clarified the judiciary's responsibility to determine the meaning and implications of laws passed by the legislature. By interpreting laws, the judiciary ensures that they align with the Constitution and uphold legal principles. This role is crucial in maintaining checks and balances within the government, as it empowers the courts to review legislation and executive actions, providing a safeguard against potential overreach by the other branches. The ability to interpret laws also establishes the judiciary's authority in interpreting constitutional provisions, thereby reinforcing the rule of law in the United States.
