The Judicial Branch interprets the meaning of the laws, applies laws in lawsuits or criminal cases, and decides whether laws or governmental actions violate the constitution.
Supreme Court
The United States Supreme Court
The US Supreme Court, located in Washington, DC, currently has nine members, although the number of justices has changed over the country’s history. It is the “court of last resort” for judicial issues in the US.
Justices are nominated by the President and confirmed by the Senate.
The court does not hear every case filed with it. The justices determine which cases to hear through a process called the writ of certiorari. If the court declines to hear a case, or reaches a tie, the lower court decision stands. This does not mean the US Supreme Court agrees with the lower court.
Justices serve for life, unless impeached.

From Lumen Learning.
Cases may come to the US Supreme Court from the state court system if a federal issue is involved. They also may be appealed from the intermediate federal appellate courts, called Circuit Courts. The court only accepts a tiny fraction of the cases it is asked to hear each year.

Lower Courts
The Circuit Courts
The Constitution gave Congress the ability to establish other lower courts to help the US Supreme Court handle the judicial case load. The intermediate appellate courts, below the US Supreme Court, are known as Circuit Courts.

From USCourts.gov
Cases may be appealed to a Circuit Court after a District Court has made a final decision. Some cases are first heard by a panel consisting of three judges. In rare cases, the case may then be reviewed by all the judges in the Circuit, called an en banc hearing.
If the losing party is unsatisfied with the Circuit Court’s decision, they can appeal to the US Supreme Court, although the US Supreme Court has discretion regarding whether to hear the case.
There are some specialized federal courts that only hear certain types of cases.
The Constitution gave Congress the ability to establish other lower courts to help the US Supreme Court handle the judicial case load. The trial courts of the federal court system are known as District Courts.
Judicial Confirmations
The President nominates potential justices when a vacancy arises on a federal court. The Senate Judiciary Committee reviews the record of the nominee and holds hearings, then votes whether to forward the nominee to the full Senate.
The full Senate then debates the nomination, then votes whether to end the debate. If the debate is successfully ended, the Senate votes to confirm. A simple majority is required to confirm.
