Describe the term "courts of appeals."

Courts of appeals are specifically designed federal courts that focus on hearing appeals from lower district courts. Their primary role is to review the decisions made by these lower courts to determine if the law was applied correctly and if proper procedures were followed. In this context, these courts do not conduct trials or hear new evidence; instead, they evaluate the legal arguments presented by the parties involved, ensuring that the judicial process was fair and just.

The function of courts of appeals is crucial because it provides a mechanism for oversight of lower courts, helping to maintain uniformity and consistency in the interpretation of the law. When appeals are made, the courts assess whether legal errors were made that would necessitate a reversal or modification of the originally rendered decision. This system allows for a check on judicial power and helps safeguard against potential injustices that may arise from district court rulings.
