Final answer:
Congress has the power to create new courts in the United States, including the District Courts, Circuit courts of appeal, and the Supreme Court. The frequency of using this power varies depending on the needs and circumstances of the country.
Step-by-step explanation:
Congress has the power to create new courts in the United States. The Judicial Power of the United States was intended to be placed solely in the hands of the Supreme Court, with Congress being allowed to establish a system of lower courts as it deemed necessary. In 1789, Congress created the United States Court System, which includes District Courts, Circuit courts of appeal, and the Supreme Court as the highest court in the land.
As for how often Congress uses this power, it can vary. Over time, Congress has established twelve Circuit Courts of Appeals and 94 federal District Courts, along with other special courts. The creation of new courts depends on the needs and circumstances of the country at different times, so there is no fixed frequency for using this power.
