List of landmark court decisions in the United States
In the United States, landmark court decisions come most frequently from the Supreme Court. Sometimes United States courts of appeals make such decisions, particularly if the Supreme Court chooses not to review the case or if it adopts the holding of the lower court. Although many cases from state supreme courts are significant in developing the law of that state, only a few are so radically different that they announce standards that many other state courts then choose to follow.
