A person who makes an appeal, especially someone who appeals a court decision to a higher court.
From 'appeal' plus the agent suffix '-er,' creating a noun for someone who performs the action. This is standard modern English terminology in legal contexts.
In law, the appealer has power even in defeat—losing at trial doesn't end the case if you can appeal. This word marks the person who refuses to accept an initial judgment and drags the case forward, sometimes for years.
