The decision on how many federal courts we have is made by the United States Congress. The Constitution authorizes the creation of the Supreme Court and gives Congress the power to establish other federal courts as needed. Congress determines the number of federal judges and courts, their locations, and the types of cases these courts can hear. This legislative control over the federal judiciary includes deciding the number of federal courts, the number of judgeships in each court, and appropriating their budgets. The judiciary itself does not decide the number of courts; it is a matter for Congress to ordain and establish inferior courts as it sees fit based on the Constitution.
