Key Facts
- Federal level: A respondent is generally the party who answers a petition, appeal, application, or administrative charge rather than the party who initiated it.
- Federal level: Federal trial-court civil cases ordinarily use plaintiff and defendant, while respondent commonly appears in appellate review, habeas corpus, Supreme Court, and agency proceedings.
- Federal level: The identity of the respondent depends on the proceeding; an agency may be the respondent in judicial review, while a custodian is ordinarily named in a habeas petition challenging present custody.
- Jurisdiction: Respondent is a procedural role, not a finding that the party acted unlawfully or will lose.
A respondent is the person, organization, government body, or official called on to answer a petition or other request for legal relief.
The correct spelling is respondent, not “respondant,” and the title identifies a party’s position in a proceeding rather than the merits of the dispute.
Respondent differs from defendant and appellee
In an ordinary federal civil action, the Federal Rules of Civil Procedure generally call the initiating party the plaintiff and the opposing party the defendant.
Petitioner and respondent are more common when a proceeding begins with a petition, while appellant and appellee are common in an appeal from a trial-court judgment.
Federal Rule of Appellate Procedure 20 connects the terms by providing that “appellee” includes a respondent in proceedings reviewing or enforcing an agency order.
The respondent changes with the kind of proceeding
Under Appellate Rule 15, a petition seeking review of a federal agency order names the agency as a respondent, and the United States is also a respondent when a statute requires it.
In Supreme Court certiorari practice, Rule 12 treats parties interested in supporting the judgment below as respondents, even if the caption below used another designation.
For a federal habeas corpus petition challenging present physical custody, the governing habeas rule ordinarily requires the state officer who has custody to be named as respondent.
A respondent in an agency enforcement matter may instead be the person or business against whom the agency issues a complaint, illustrating why the governing statute and procedural rules control the label.
The role carries procedural rights and obligations
A respondent may answer, oppose requested relief, present arguments, and participate according to the rules for that forum, but exact deadlines and filing requirements vary by proceeding.
For example, Appellate Rule 15 gives a respondent 21 days to answer an application to enforce an agency order, while Supreme Court briefing follows a different timetable.
The word does not describe evidence strength, liability, guilt, or the likely outcome; it simply identifies the party responding to a particular procedural request.
Related terms can overlap without becoming interchangeable, so the case caption, initiating document, and governing rule provide the most reliable explanation of who the respondent is; a separate overview explains the role of a counterclaim when an opposing party asserts its own claim.
