An appeal is a request for a higher court to review a lower court's decision. An appeals lawyer handles cases on appeal when a party loses or wants to challenge a part of a decision made by the lower court. The appeals court reviews the record made in the trial court.
In appealing a case, no new facts or evidence can be added to the record. Based on written briefs, the appeals court decides whether to affirm or reverse the trial court's decision. Appeals cases are typically handled by an experienced lawyer skilled at research and writing.
