Federal Courts are the judicial branch of the United States government, responsible for interpreting and applying federal laws. They handle cases involving federal statutes, constitutional issues, and disputes between states or citizens from different states. The system includes various levels, such as District Courts, Courts of Appeals, and the Supreme Court of the United States, which is the highest court in the land. These courts play a crucial role in upholding the rule of law and ensuring justice is served. They also have the authority to review decisions made by lower courts, making them essential for maintaining legal consistency across the nation.
