A more thorough explanation:

In a legal context, the Court of Appeal(s) refers to:

• An intermediate appellate court that hears appeals from rulings and judgments of lower trial and appeals courts. This court has the power to penalize lawyers for any duty violation, willful neglect, or disobedience of any lawful court order. An attorney’s refusal or neglect to obey a court order from a court of appeal(s) is considered an act of contempt.
• The highest court in some states, equivalent to the State Supreme Court. For example, in New York, Maryland, and Virginia, the highest state court is called the Court of Appeals.

For instance, if a person is unhappy with the decision made by a lower court, they can appeal to the Court of Appeal(s) to review the case and make a new decision. The Court of Appeal(s) has the power to uphold the lower court's decision, reverse it, or send it back to the lower court for further review.

Another example is if a lawyer disobeys a court order from the Court of Appeal(s), they can be held in contempt and face penalties such as fines or even imprisonment.
