What is an appeal?

A judgment may be appealed, but an error of law must be proven to have a successful appeal and most appeals do not succeed. Appellate courts are loath to overturn lower courts. Unless a bond is posted, the party winning can normally enforce a judgment even during an appeal and since appeals often take years, the party appealing often posts a bond to save itself from enforcement of judgment during the period of waiting for a final decision from the appellate court.
