Appellate law is the practice of asking a higher court to review a decision made by a lower court. An appeal is not a new trial; it is a focused review of whether the lower court applied the law correctly and followed proper procedures.
Appeals can arise from many kinds of cases, including civil disputes and other matters decided by a trial court or, in some situations, an agency. The appealing party argues that an error affected the outcome, while the other side defends the decision. Appellate work centers heavily on written briefs and the record from the lower court, sometimes followed by oral argument before a panel of judges.
Key concepts a non-lawyer should understand include the idea that appellate courts generally do not hear new evidence or new witnesses; that they review the existing record for legal error; and that they tend to give some deference to a trial court's factual findings while reviewing legal questions more closely. Appeals are also governed by strict deadlines and procedural rules, and possible outcomes include affirming, reversing, or sending a case back for further proceedings.
People typically consult an appellate lawyer when they believe a significant legal error affected the result of their case, or when they must defend a favorable decision that the other side is appealing. Appellate work often calls for skills distinct from trial practice.
