The judicial branch helps to set and clarify rules to maintain a balance in power and control between the executive branch and legislative branch, which are the other two branches of United States government. The federal government contains three main branches of government, which perform separate but complementary and equally important roles. The U.S. Constitution lays out the specific duties and obligations held by the three branches of government and within the judicial branch lies the power to use judicial review to interpret rules, particularly in the areas of criminal and civil law.
The judicial branch functions as a single, cohesive unit that contains several units. Among the most well known and most important of those units is the Supreme Court. The Supreme Court is the primary operational body of the judicial branch. Nine justices sit on the bench of the Supreme Court at any given time. The justices accept and hear cases assigned to the Supreme Court. The Supreme Court contains nine justices to help expedite hearings and reduce the number of cases received by the Court. . In addition to having the Supreme Court, the judicial branch is involved in cases involving civil law and criminal law, primarily at the federal level. The judicial branch sets rules and regulations regarding other areas of law, too, and has the ability to review and comment on legal cases involving affairs that affect the public.
