An appeal is different from a trial because an appeal is
an opportunity

An appeal is a legal proceeding by which a case is brought before a higher court for review of the decision of a lower court, for example, if e verdict has been made and the lawyer is not satisfied with it, he can appeal.

A trial is a formal examination before a competent tribunal of the matter in issue in a civil or criminal cause in order to determine such issue.
