Other forms: appellants
An appellant is someone who has filed a request asking a judge to change an earlier legal decision.
When someone who's been convicted of a crime files an appeal, hoping for a different outcome in a new courtroom, they become an appellant. Usually with the help of an attorney, the appellant submits written arguments in favor of an appeal to a judge. The opposing side does the same, and the judge decides whether or not the case warrants another trial. Appellant is from the French appeller, "make an appeal," and a Latin root meaning "appeal to."
