The role of the judicial branch in the U.S. government is to explain laws of the country, determine if laws are constitutional and regulate the federal court system, according to WhiteHouse.gov. Members of the judicial branch are appointed by the president with confirmation from the Senate.
As stipulated in Article III of the Constitution, which provides for the legal establishment of the judicial branch, Congress has discretion to establish and modify the structure and shape of the federal judicial system with power to establish the number of supreme court justices who serve, according to WhiteHouse.gov. The role of the judicial branch also provides Congress with the power to create lower courts under the umbrella of the Supreme Court, such as district courts that can try federal cases, and the United States Courts of Appeals to review federal court cases. An additional role of the judicial branch is to ensure that each individual has the right to a fair trial, as outlined in Article III of the Constitution. The judicial branch evaluates the protections outlined in the fourth, fifth and sixth amendments of the Constitution that provide individuals with the right to a speedy trial, legal representation, protection from excessive fines and bail, and the guarantee that an individual is not deprived of property, life or liberty without due process, according to WhiteHouse.gov.
