Difference Between Appellant and Petitioner

Key Differences

An appellant is specifically someone who appeals a lower court's decision, seeking a review from a higher court due to perceived errors in the application of law. In contrast, a petitioner refers to any party who presents a petition to a court, which could be for purposes of initiating a lawsuit, requesting a legal remedy, or even appealing in some contexts.
Appellants are always involved in appellate processes, reflecting a reactive legal stance to an earlier ruling. On the other hand, petitioners cover a broader spectrum, including initiating actions, which might not necessarily relate to a prior judgment.
While an appellant’s role activates only after a decision they wish to challenge, a petitioner’s role can be proactive, setting a legal process in motion.
This means the term "petitioner" is used in a variety of legal contexts, from family law to bankruptcy, whereas "appellant" is strictly used within the framework of appeals.
