Concept:
Legal terminology differentiates between parties at the trial stage and the appellate stage. When a case moves from a lower court to a higher court, the names of the parties change to reflect their role in the appeal process.
Step 1: Defining the parties in an Appeal.
When a judgment is passed by a lower court, the party dissatisfied with the outcome has the right to file an appeal in a higher court.
• Appellant: The person/party who files the appeal.
• Appellee (or Respondent): The person/party against whom the appeal is filed (usually the winner of the lower court case).
Step 2: Analyzing the other terms.
• Petitioner: A person who files a petition (often used in writ jurisdictions or original matrimonial suits).
• Contestant: A general term for someone participating in a competition or dispute, but not a standard legal designation for an appealing party.
Step 3: Conclusion.
The question asks for the specific party who is filing the appeal. By legal definition, this person is known as the Appellant.
$\text{Action: Filing Appeal} \rightarrow \text{Title: Appellant}$
Final Answer: Option B
