The levels of the court system are district, state, and then federal. Even if someone's case reaches the supreme court (federal) level the court does not have to take the case. An example of someone's case making it to the supreme court level and the court reviewing the case in Dred Scott v. Sandford. Dred Scott was a slave who to a free state with the consent of his slave master at the time Emerson. Emerson eventually died and when he died Scott tried to purchase his freedom along with his family's, but the state would not allow him to. According to Dred Scott v. Sandford - Case Summary and Case Brief (legaldictionary.net), "When Emerson died, Scott tried to purchase both the freedom of himself and his family, but the estate refused." After reaching a verdict on a case the supreme court judges have to complete opinion writing which can take weeks or months to complete.
This case led to the 14th amendment which states "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside." This allowed for citizens who were once categorized as property to be liberal which means to feel free. This case is also an example of judicial activism when the court is willing to make fast sweeping change in the law. This case was the opposite of judicial restraint when the court makes slow or no change within the law.
