Definition - What does Appellant mean?
An appellant is a person that takes an appeal case to a higher court in order to seek a reversal of judgment of a case ruling that has been ruled against them. Any party that is involved in a court case can appeal the decision of the court if they do not agree with it. This means that it would be reviewed by a higher court. There is no legal requirement for the higher court to hear the appeal; the appeals court will judge the merit of the capase and determine whether cause exists to review the decision of the lower court.
