§ 7804.Procedure.
Article 78. Proceeding Against Body or Officer · Last amended 1993 · Last verified July 21, 2026
Full Text of CPLR 7804
Plain-English Summary
Subdivisions (a) and (b) frame the basic structure: an Article 78 proceeding is a special proceeding, and it's brought in supreme court in the county fixed by CPLR 506(b), unless that provision says otherwise. Subdivision (c) then lays out the timetable: notice of petition, the petition itself, and supporting affidavits go out at least twenty days before the hearing date unless the court sets a different schedule through an order to show cause; the answer and its affidavits follow at least five days before the hearing; a reply follows at least one day before. Proceedings against a state body or officer, or against officials whose terms have expired, require separate service on the attorney general, and proceedings against members of a governmental subdivision's body whose terms have expired require service on that subdivision under CPLR 311.
Subdivision (d) requires a verified petition, permits accompanying affidavits or other written proof, and, where there's an adverse party, requires a verified answer stating the facts behind the respondent's challenged action. Subdivision (e) requires the respondent to file a certified transcript of the record along with the answer, unless already filed, and lets the court order the respondent to fix any defect or omission; if the respondent defaults by failing to answer or move to dismiss, the court can enter judgment for the petitioner or order an answer submitted. Subdivision (f) lets a respondent raise objections in point of law either in the answer or by a motion to dismiss, with a structured process for what happens if that motion is denied.
Subdivision (g) is where the substantial-evidence question from CPLR 7803(4) becomes procedurally distinct: if that issue isn't raised, the court hearing the proceeding decides everything itself, but if it is raised, the court first resolves every other objection that could end the case, jurisdiction, statute of limitations, res judicata, without touching substantial evidence, and only if the case survives does it get transferred to the Appellate Division for disposition of the substantial-evidence question. Subdivision (h) covers trial of any triable issue of fact, whether before the original court or, after transfer, before a referee or supreme court justice reporting back to the Appellate Division. Subdivision (i) adds special protections when a proceeding targets a judge, justice, referee, or judicial hearing officer over an act performed in a case still pending: the petitioner must serve all other parties to that pending case, the respondent judicial officer isn't required to appear, and if the officer chooses not to, no allegation is deemed admitted or denied, though any ruling still binds that respondent.
Frequently Asked Questions
Where do you file an Article 78 proceeding in New York?
In the supreme court, in the county specified by CPLR 506(b), except as that subdivision otherwise provides.
How much notice do you need to give before an Article 78 hearing?
At least twenty days for the notice of petition, petition, and affidavits, unless the court sets a different schedule by order to show cause; the answer is due at least five days before the hearing, and a reply at least one day before.
What has to be filed with the answer in an Article 78 proceeding?
A certified transcript of the record of the proceedings under review, unless already on file, plus affidavits or other written proof of the evidentiary facts entitling the respondent to a trial of any factual issue.
What happens if the substantial evidence question is raised in an Article 78 case?
The court first decides every other objection that could end the case, like jurisdiction, the statute of limitations, or res judicata, and only if the case survives does it transfer to the Appellate Division to resolve the substantial-evidence issue.
What happens if a government respondent doesn't answer an Article 78 petition?
The court can enter judgment for the petitioner or order that an answer be submitted, since a default doesn't automatically end the case in the petitioner's favor without court action.
Do you have to serve the attorney general in an Article 78 proceeding against a state agency?
Yes. In addition to serving the state body or officer, the order to show cause or notice of petition must be delivered to an assistant attorney general in the county where venue is designated.
What special rules apply to an Article 78 proceeding against a judge?
If the proceeding challenges an act the judge performed in a still-pending case and the judge isn't a named party there, the petitioner must serve all other parties to that pending case, and the judge need not appear unless the court orders it.
Advisory Committee Notes
Subd (a) of this section makes article 4, which governs matters of procedure in special proceedings generally, applicable to a proceeding under this article. It eliminates the need to repeat here a number of provisions in CPA, article 78. Thus, the first two sentences of CPA § 1289, which required eight days’ notice of the application unless a shorter time was prescribed by an order to show cause, and which required that the petition and supporting papers be served with such notice or order, are covered by subdivisions (b) and (d) of § 403. The authorization of a reply in CPA § 1292 is covered by §§ 403(b) and 402. See also § 3011. Objections in point of law in special proceedings are governed by § 404, which was patterned after § 1293 in CPA article 78; and motions to supply defects in the record or to correct the pleadings are covered by § 405, which was patterned after § 1294 in CPA article 78. The remaining subdivisions of this section deal with matters of procedure that are unique to a proceeding under this article. Matters of procedure not regulated by either this article or article 4 or special statute will be governed by the same rules that govern procedure in actions, by virtue of § 103(b), which eliminates the need for CPA § 1306.
Subd (b) of this section is derived from part of CPA § 1287. The remainder of § 1287, which dealt with venue, is treated in § 506.
Subd (c) of this section parallels the language of subd (b) of § 403, dealing with special proceedings generally. A basic time period of twenty days has been provided. It seems to be the consensus of those concerned with CPA article 78 proceedings that the former period almost invariably required an adjournment and that the new period is more realistic.
Subd (d) of this section is based upon § 402, in the special proceeding article modified to incorporate the language of CPA § 1292 concerning replies.
The first sentence of subd (e) of this section is derived from part of CPA § 1291. Other parts of § 1291 are covered in the provisions on answering affidavits in the title on special proceedings. The latter article permits a “counterclaim” (i.e., a demand for relief by the body or officer) formerly prohibited by § 1291. Since the proceeding is before the court, determination of the propriety of cross-relief can easily be made. Moreover, the counterclaim may be severed if it will delay decision of the issues raised in the petition. See § 603. The second sentence of this subdivision covers the situation envisaged by CPA § 112. That section was a holdover from the pre-article 78 proceedings to review the determination of a body or officer. In the Throop Code it appeared, together with the other provisions relating to those proceedings, as § 2124; at that time it authorized an appellate court reviewing the determination of a body or officer to issue a writ of certiorari requiring the body or officer to supply any “diminution, variance, or other defect, in the record or other papers.” The authors of the civil practice act substituted the use of an ordinary order for the same purpose and removed the section to its position in the article governing “Mistakes, Defects and Irregularities,” while the rest of the provisions governing certiorari, mandamus and prohibition were placed in former articles 78–80. See Report of the Joint Legislative Committee on the Simplification of Civil Practice 111 (1919). The 1937 revision which produced CPA article 78 took no account of § 112. See 3 NY Jud Council Rep 129–98 (1937). According to Throop’s note the section served a purpose analogous to that of the provision permitting a respondent in an ordinary appeal to transmit the papers to the appellate court, if the appellant failed to do so, and tax the expense thereof as disbursements. See Code Civ Proc § 2124, note (Throop ed 1880); id. § 1315; cf. CPA § 607-d. Apart from the question of costs, there is no problem of “diminution, variance, or other defect” under former appeals practice or article 55, since both parties have equal access to the papers and there is ample provision for settlement of a transcript of the proceedings below. See rules 5525, 5527 and 5530. But to the extent that this may not be true where the proceeding was before a body or officer, there may be a need for a procedure to compel the body or officer to supply defects in the record. In former article 78, § 1294, allowing either party to “apply to the court to correct any omissions or defects in the papers,” would take care of this problem and therefore CPA § 112 is unnecessary. But CPA § 1294 has been omitted from this article and consequently this subd requires this sentence. The third sentence of the subdivision is derived from part of CPA § 1296. While it seems to state the obvious, it is included to avoid the result reached before its adoption when statements of fact in the return were held binding on a petitioner in certiorari. See 3 NY Jud Council Rep 164–67 (1937).
Subd (f) of this section is based upon subd (a) of § 404 in the special proceeding article, modified by requiring that the respondent be given an opportunity to answer if the motion is denied. Under § 404, the court may deny such an opportunity if the objection in point of law is overruled.
Subd (g) of this section follows former practice as provided for in the paragraph following subd 7 of CPA § 1296.
Subd (h) of this section is derived from CPA § 1295. Procedure on the trial is governed by the applicable provisions of articles 40 through 45. The statement that trial is to be had “forthwith,” includes a jury trial where one is required. Article 4, applicable to special proceedings generally, so indicates. Cf. § 2218, applicable to motions. There is a right to trial by jury in proceedings in the nature of mandamus (3 NY Jud Council Rep 138, 168–69 (1937); 1 Benjamin, Administrative Adjudication in New York 358–59 (1942)) and on certain issues in proceedings in the nature of certiorari (3 NY Jud Council Rep 188 (1937)) but not in proceedings in the nature of prohibition. Id. at 167. The subdivision does not state in what actions jury trial is available, or what questions are to be submitted to the jury since these are matters which are governed by historical rights under the writs. The proper scope of a jury, however, is still not wholly resolved by case law. See 1 Benjamin, op cit supra at 355–58. The second sentence of this subdivision is required because a proceeding against a justice of the Supreme Court, which may raise a question of fact, must be brought in the Appellate Division. See § 506; CPA § 1287.
