Apart from specialized courts, the federal court system comprises the following:
The Supreme Court of the United States
Most cases are appeals from lower courts. In addition to cases from lower federal courts, cases from state supreme courts which involve a point of federal law may be heard. The court has discretion to decide which cases will be considered.
U.S. Courts of Appeals (also called Circuit Courts of Appeals)
Appellate courts which deal with appeals from the district courts in their circuit.
U.S. District Courts
Trial courts which deal with violations of federal criminal law, disputes regarding federal laws or treaties, and some cases between residents of different states.

It is the most complete and authoritative source for all of the Court’s audio since the installation of a recording system in October 1955. Oyez offers transcript-synchronized and searchable audio, plain-English case summaries, illustrated decision information, and full-text Supreme Court opinions (through Justia). Oyez also provides detailed information on every justice throughout the Court’s history and offers a panoramic tour of the Supreme Court building, including the chambers of several justices.
The decisions in this collection have all been gathered into topical groups. (Many have been listed under several headings.) Clicking on any listed topic will retrieve all opinions classified under it. Instead of or in addition to using these topical groups you can search the entire collection for decisions using particular key words or phrases.
