What is the main job of the head of the judicial branch?

The primary role of the head of the judicial branch is to interpret laws. This function is essential because the judicial branch, which includes courts and judges, is responsible for resolving disputes, ensuring justice, and applying the law to specific cases. When laws are ambiguous or contested, it is the judiciary's duty to clarify their meaning and ensure they align with the constitution. This interpretation can set precedents that guide future cases, thereby influencing how laws are understood and applied across the legal system.

The other functions listed, such as enforcing laws and creating laws, fall under the roles of the executive and legislative branches, respectively. The separation of powers in government ensures that each branch has distinct and limited functions to prevent any one branch from gaining too much power.
